Of course, no owner will refuse to have a reliable and at the same time quite affordable roof on his home. A well-planned manual installation will not only protect all structures from bad weather and possible damage, but also save a significant amount of financial resources. So, all of these qualities are possessed by an innovative soft roof made of flexible tiles, the basis of which is bitumen. Therefore, it is important to understand how to properly install a roof made of flexible tiles.

It is necessary to study in detail how flexible tiles are laid, the installation technology of which has some of its own characteristics. Only strict adherence to each stage of its installation will allow you to create a reliable and durable roof. Exactly about technical specifications soft tiles, as well as the method of their installation will be discussed further.

What are flexible tiles made of?

Roofing made from this material also has some other names, such as shingles, shingles or roofing tiles. The main advantages of such a roof are its light weight (the weight of one sheet is on average 8 kilograms) and its not too high cost compared to metal tiles. Thanks to the first indicator, the structure of the house is not so massive, which allows you to save on construction materials and labor costs, and the second characteristic allows the roof to seriously compete with other, heavier roofing types.


The basis of such tiles is usually fiberglass or fiberglass (less commonly, organic cellulose) impregnated with bitumen. These materials perform the functions of so-called reinforcement, which holds two layers of SBS modifier together, which directly affects the flexibility and elasticity of the coating. Outside, the material is sprinkled with slate, mineral chips and basalt granulate. They are able not only to protect the material from damage, but also to give it a variety of shades of color.

Preparatory work for laying soft tiles

The basis for soft tiles is particle board, moisture-resistant plywood or boards. When choosing boards, you need to carefully select high-quality material. The best option will be the use of planed tongue and groove boards. If its thickness is 2 centimeters, then the rafter pitch should be 6 meters. With a thickness of 2.5 - 3 centimeters, the step can be 1.2 meters. Minimum thickness plywood is a distance of 1.2 centimeters (rafter pitch is 6 meters), with a thickness of 2 centimeters, the rafter pitch is 1.2 meters. One way or another, the joints of the material must correspond to the rafter legs. When working with a material such as flexible tiles, it is recommended to treat the installation of the base with an antiseptic. It is important that the boards used during installation are dry. The base coating should be hard and even.


In addition to the coating itself and the base material, during installation you cannot do without the following elements:

  • underlay carpet, which can be represented by any bitumen roll material provided that the shingle roof is new. For an old roof, you can also use roofing felt that has already been used;
  • valley carpet, the role of which is played by bituminous material using polymers, necessary to protect connections to walls and ventilation pipes from moisture.

When laying carpet, you must use following materials:

  • roofing sealant or mastic;
  • construction hot air gun;
  • knife for cutting material;
  • three types of nails: regular, roofing and galvanized;
  • construction strips required for processing junctions, cornice and front.


When all the parts have already been assembled and the installation of flexible tiles is carried out, the instructions require compliance with the following set of rules when working:

  1. Initially with inside the roof must be secured with a vapor barrier film. The material is attached to the rafter legs using nails, and to the ends - wooden planks. The film strips are connected using tape.
  2. After this, you need to lay insulation on the outside, to fix which it is customary to use wooden blocks.
  3. A film is placed on the insulation to protect the roof from the wind. To fasten it, a counter beam is used, to which the sheathing will need to be nailed.
  4. After this, boards, strand board or plywood are laid. The material is secured with nails equipped with a wide head or self-tapping screws.

Laying flexible tiles

When arranging a roof with soft tiles, you should first of all take into account temperature conditions, since the structure of the material requires a special approach. The greatest strength of connection between shingle elements will be ensured only by heat, sun and absence of any precipitation, and installation of flexible tiles in winter is not recommended, since this may lead to the falling off of the slightly previously glued tiles (read: ""). Sometimes in cold weather it is permissible to use a hot air gun to heat the coating sheets. You can also heat the adjacent attic (attic) space.


  1. Initially, the installation of the lining carpet is carried out. It must be spread and nailed over the following areas of the roof:- cornice;
    - ;
    - valleys;
    - skate;
    - places where the roof slope is broken.

    Provided that the roof slope is more than 20 degrees, the lining carpet must cover the entire roof area. You need to start work from the bottom, and the carpet should be perpendicular to the sheathing. It is nailed with an overlap (width - 15 centimeters) with a fixing step of 20 centimeters. It is important that each of the joints is carefully treated using bitumen mastic or a special roofing sealant. A cornice strip is nailed onto the spread carpet, designed to protect the sheathing from moisture. If it is not possible to do this, then the cornice strip is simply wrapped under the sheathing base. They nail it down using galvanized nails in 5-centimeter increments.


  2. Then work on the construction of the pediment is carried out. It also needs to be nailed end strips, which are designed to provide wooden sheathing protection and remove moisture down from the ridge. After installing them, you can begin installing the ridge-eaves covering strips, which can simply be represented by soft tiles with cut off edges. Nail them joint to joint, retreating 2.5 centimeters from the edge. It is recommended to treat these areas with bitumen-based mastic; it is also used to secure the free edges. At this stage of the work, it is also worthwhile to fix the drainage elements - brackets that are used under the gutter.
  3. Flexible roofing, the installation of which has certain features, requires the laying of a valley carpet. It needs to be laid on top of the main one, that is, as a second layer. This carpet should be located in areas of junctions, recesses and other places that are optimal for the accumulation of excess moisture. It is fastened using galvanized nails in increments of 10 centimeters, and the edges are treated with bitumen mastic. If possible, it is better to use special glue - waterproof.
  4. It is after completing all these procedures that you should proceed directly to. The material must be from different packages, since the sheets in them have different shades. After graduation installation work Under the influence of the sun, the material will gradually acquire a uniform color. You need to start laying from the bottom of the central section of the slope. The adhesive part of the material must be stripped of the protective film, and the coating must be pressed tightly to the base. It must be nailed on top using 4 nails, departing 4 - 5 centimeters from the ridge-eaves strip. The petals of the material should completely cover the perforation of the strip located below. From the edges of the gable line, the coating should be cut to the required length and treated with mastic.


  5. Extremely important point is also the intersection with the chimney and ventilation systems. The underlayment carpet should be installed initially in this area. The ventilation base should be treated with bitumen mastic. Next, you need to select one of the fragments of flexible tiles and make a hole in it corresponding to the ventilation device (read: ""). After finishing laying the coating, the base must be treated with mastic again.

Working with a chimney is more difficult. At the point where it contacts the roof, three triangular slats should be nailed, located at right angles to the pipe. Then a lining carpet is laid around the chimney, which is overlapped and treated with the same mastic (read also: "

The main elements for ensuring normal temperature and humidity conditions of the roof are vapor barrier and insulation required thickness(depending on the region), windproofing material, ventilated under-roof space.

Shingles with the same color codes and manufacturing dates should be used on the same roof. The shades of bituminous shingles from different batches may vary slightly. To avoid color imbalance, Euromet specialists recommend mixing tiles from several packages before starting installation. To make it easier to separate the shingles from each other, the packaging can be slightly bent and shaken before opening.

If the roofing installation is carried out at temperatures below +5° C, the packages with tiles must be kept in a warm room before installation. The self-adhesive layer of material must be heated using a heat (construction) hair dryer.

When cutting a soft roof, a special board should be placed under it so as not to damage the bottom covering.

During storage, Shinglas bitumen shingles must be protected from direct sunlight, since under their influence the adhesive layer can sinter with the protective film. Pallets of material cannot be stacked on top of each other.

You should not walk on the roofing in sunny and hot weather; marks and stains from shoes may remain on it. It is recommended to move on the roof using special manholes.

Materials used

Shinglas

SHINGLAS flexible tiles differ from similar products of others Russian manufacturers a wide range of colors and cutting shapes. Currently, there are about 50 different models of Shinglas flexible tiles on the domestic market.

Underlay carpet TechnoNIKOL

Self-adhesive backing materials:

  • ANDEREP ULTRA is a self-adhesive underlay carpet with increased strength. High reliability of the material is achieved due to a durable polyester base and high-quality bitumen-polymer binder. The top protective layer of the lining carpet is made of fine-grained sand.
  • ANDEREP BARRIER – baseless self-adhesive material. A thick reinforcing film is used as the top protective layer. The absence of a base allows you to maintain the integrity of the waterproofing material in the event of deformation of the base.

Lining materials with mechanical fixation:

  • ANDEREP PROF – has a durable polyester base and a non-slip polypropylene top coating. Thanks to a special bitumen-polymer mixture, the material can “self-heal”, that is, it maintains tightness in places where nails enter.
  • ANDEREP GL is a lining material with double-sided protection of the polymer mixture by layers of fine-grained sand.

TechnoNIKOL valley carpet

The TechnoNIKOL valley carpet is a rolled bitumen-polymer material. It is made on the basis of polyester, has a protective coating of coarse-grained basalt granulate. Used as a waterproofing layer in valleys and places that are subject to the greatest loads.

Junction strips, cornice and gable overhangs

Metal elements with a special protective (anti-corrosion) coating.

Roofing nails

Special galvanized nails are used. The diameter of the nail stem is from 3 mm, the head is from 9 mm, length is 25-30 mm.

TechnoNIKOL mastic No. 23 (FIXER)

Bitumen-polymer mastic for gluing flexible tiles and other bitumen-based materials to various surfaces.

Ventilation elements TechnoNIKOL

Elements for equipping the required number of supply and exhaust openings to provide under-roof ventilation.

Roofing material consumption

Roof tiles. Each package of Shinglas soft roofing series "Country" and "Jazz" contains a quantity of tiles sufficient to cover 2 m 2 of roofing (including overlaps). In packages of Shinglas flexible tiles - for 3 m 2 of roofing. Calculation of the amount of material should be made taking into account the coefficient, the value of which depends on the complexity of the roof. The waste of bituminous shingles with cutting shapes "Accord", "Sonata", "Dragon Tooth" together with ridge-eaves tiles is up to 5%. For the rest of the tiles, when calculating the amount of material, waste should be taken into account at the level of 10-15% (including consumption for the starting strip, ridges and roof ribs).

Roofing nails. The required number of roofing nails is determined at the rate of approximately 80 g per 1 m 2 of roofing.

TechnoNIKOL mastic No. 23 (FIXER). For the valley carpet, 400 g of mastic per 1 line of space is consumed, for the end parts - 100 g per 1 line of space, for sealing the junctions - about 750 g per 1 line of space. Do not dilute the mastic with solvents and apply it in a thicker layer 1 mm, this can lead to leaks and swelling of the material.

Preparing the roofing base for installation

1. Installation of flooring under flexible tiles

Quite strict requirements are imposed on the base for soft tiles. It must be rigid, continuous and even (differences in height of no more than 1-2 mm are allowed). The large-panel flooring is laid with staggered seams; self-tapping screws or rough nails are used to secure it. During installation wooden flooring you need to pay attention to the fragments of the annual rings and lay the material so that their bulges face down. If the installation of a base made of OSB-3 or plywood is carried out in the cold season, a gap of 3 mm wide should be left between the sheets. This will avoid deformation of the flooring during thermal expansion of the material in the summer.

Before installing the boardwalk, you must first sort the boards by thickness. They are laid so that the thickness of the base changes gradually. In this case, thicker boards are laid closer to the eaves, and thinner ones are laid near the ridge. The joints of the boards must be located on supports; in these places the boards are fixed with at least 4 nails. If damp wood is used, the boards are secured with 2 screws on each side.

To strengthen the eaves overhang, metal eaves strips are used. These elements protect the roofing material in the eaves area from the effects of precipitation. The eaves strips are attached to the edge of the solid base with roofing nails. The nails are driven in a checkerboard pattern at a distance of 12-15 cm from each other. The planks are laid overlapping, the width of the overlaps should be 3-5 cm. In places where there are overlaps, nails are driven in increments of 2-3 cm.

The underlayment carpet is installed over its entire area for any roof slope. In the area of ​​eaves overhangs and valleys, self-adhesive lining material ANDEREP or other similar material is laid. It serves as an additional protective coating in areas of the most likely leaks.

On eaves overhangs, the width of the self-adhesive underlayment should be 60 cm greater than the width of the eaves overhang. The width of the cornice overhang is measured from the plane of the inner side of the outer wall of the building, as shown in the figure. The bottom edge of the carpet should be 2-3 cm above the edge of the cornice strip.

A self-adhesive lining carpet 1 m wide is laid in the valleys (each slope is covered by 50 cm). It is desirable that the carpet be continuous along the entire length of the valley. If two or more sheets are used, they are laid overlapping. The width of the overlaps should be 30 cm, the seams should be carefully taped.

Underlay material with mechanical fixation ANDEREP or other similar material is installed on the remaining surface of the roof. The canvases are laid parallel to the eaves overhang. Installation of the underlayment begins from the bottom of the roof slope and gradually moves up to the ridge. The width of the overlaps in the longitudinal direction should be 10 cm. An exception is organic-based lining materials (for example, BiCARD). For them, when laying on a roof slope with a slope of up to 30°, the width of the overlaps should be 60 cm, and with a slope slope of more than 30° - 10 cm. The overlaps of the sheets in the transverse direction are made 15 cm wide.

The underlay carpet is secured with galvanized nails with wide heads; the nails are driven in at a distance of 20-25 cm from each other. Overlapping areas 8-10 cm wide are coated with TechnoNIKOL No. 23 mastic.

Note. When installing with cutting shapes “Accord”, “Sonata”, “Trio”, “Beavertail”, it is allowed to install the lining material only in places where leaks are most likely. It is laid in strips 50 cm wide along the perimeter of the roof (and along eaves overhangs up to 60 cm above the plane of the inner surface of the walls, see figure), 1 m wide in the valleys, 50 cm around the perimeter skylights and 1x1 m around the passage elements. The terms and conditions of the warranty change and become similar to those for products from other manufacturers. The climate in different regions of Russia is significantly different, so this note does not apply to all regions, but only to the Central Federal District, Southern Federal District, Volga Federal District, Northwestern Federal District and Northwestern Federal District.

4. Strengthening gable overhangs

To strengthen the gable overhangs, metal end strips are used. They are fixed on top of the lining material with roofing nails in increments of 12-15 cm, the nails are driven in a checkerboard pattern. The end strips are laid with an overlap, the width of the overlaps should be 3-5 cm, in these places the nails are driven in every 2-3 cm. When installing a Shinglas soft roof, the gable strips are coated with mastic and the upper corners of the outer shingles are cut off.

5. Preparing the valley

There are two ways to install Shinglas soft roofing in valleys – open and the “undercut” method. The preparation of the valley depends on which method will be used.

Along the axis of the valley (1) on top of the self-adhesive lining material (2) a TechnoNIKOL valley carpet (3) is laid with a horizontal offset of 2-3 cm. On the bottom side, the valley carpet along the perimeter 10 cm from the edge is coated with TechnoNIKOL bitumen mastic. When using open method valley devices, the valley carpet can be replaced with a metal strip with anti-corrosion coating. This replacement is appropriate for regions with hot climates. The valley carpet (or metal strip) is secured with roofing nails; they are driven in at a distance of 2-3 cm from the edge of the material in increments of 20-25 cm. It is advisable to lay a continuous (without overlaps) valley carpet along the entire length of the valley. If this is not possible, parts of the carpet are laid overlapping. The overlaps are made 30 cm wide; the material in these places must be carefully glued.

Undercut method

When installing a valley using the “cutting” method, there is no need to install a valley carpet.

6. Marking the roof slope

The markings are guide lines that, when laying soft tiles, help to align them vertically and horizontally. This is especially true in the case of incorrect geometry of the roof slope and the presence of any structures embedded in the roof. Vertical lines are applied in increments equal to the width of the shingles of ordinary tiles. 5 rows of material should be placed between the horizontal lines, so they are applied approximately 80 cm from one another. It should be remembered that the markings only serve as a guide and are not a guide for fixing the bitumen roof.

Before installation, shingles from several packages are mixed or sheets are taken from them one by one.

If Shinglas will be installed at low temperatures (below +5°C), the packages must be placed in the oven for at least 24 hours in advance. warm room(+20°C). From there, several packages are served immediately before work begins. The self-adhesive strip on the tiles should be heated using a heat (construction) hair dryer.

When working on the roof, the material should be cut on a supported board so as not to damage the underlying roof covering.

In sunny and hot weather, you should not walk on the laid roofing, as marks and stains may remain on it. You need to move along the roof using special manholes.

2. Rules for fixing ordinary tiles

Each shingle is secured to the base with galvanized nails with wide heads. The number of fasteners depends on the angle of inclination of the roof slope. For a slope of up to 45°, each shingle is nailed with four nails; for slopes greater than 45°, with six nails. The nails should be positioned evenly and driven in so that the heads do not cut into the surface of the soft roof, but are in the same plane with it (see figure).

The location of fasteners for all forms of Shinglas cutting is shown in the figure. On both sides, shingles are nailed at a distance of 2-3 cm from the edge.

3. Starting line

For the starting strip, use universal ridge-eaves tiles or shingles of ordinary soft tiles with cut petals.

Ridge-eaves bitumen shingles are used as a starting strip when laying Shinglas with “Accord” and “Sonata” cutting shapes. It is laid on top of the cornice strips 1-2 cm above their bend (see figure). The width of the indentation from the bend of the eaves strips depends on the slope angle and the length of the roof slope. The longer and steeper the slope, the wider the indentation should be.

When installing flexible Shinglas tiles with cutting shapes “Beaver Tail”, “Trio”, “Accord”, “Sonata”, shingles with cut petals are used for the starting strip. Before laying, their lower side in places where there is no adhesive layer must be coated with TechnoNIKOL mastic. Patterns from ordinary tiles are mounted in the same way as ridge-eaves tiles.

The starting strip for sheets with the “Dragon Tooth” cutting shape is made from ordinary tile shingles; there is no need to cut them. Their installation is carried out similarly to ridge-eaves tiles.

4. Laying the first, second and subsequent rows of tiles

On long roof slopes, it is recommended to start laying the material from the middle of the slope, this will make it easier to level it horizontally. 1-2 cm are retreated from the initial (central) strip and the first shingle is installed (see figure). In this case, you should pay attention to the fact that the joint of the shingles of the first row does not coincide with the joint of the elements of the starting strip.

Installation must be done in diagonal stripes (see figure).

Depending on the cutting shape, the soft roof can be laid in diagonal strips, in the form of a pyramid or a vertical strip (see pictures). The shingles of the second row begin to be laid from the middle of the slope, with a horizontal shift in any direction by half a blade relative to the shingles of the first row. In this case, the lower edge of the tabs of the second row of shingles should be located at the level of the upper edge of the cutouts on the shingles of the first row.

The sheets of the third row are mounted offset by half a blade relative to the shingles of the second row in the same direction as when laying the previous row.

It is recommended to coat the outer shingles of ordinary tiles in places where there is no adhesive layer with TechnoNIKOL bitumen mastic to a width of 10 cm from the edge of the roof. Their upper corners are cut by 2-3 cm for more efficient water removal.

Note: laid with an offset of 15-85 cm relative to the previous row. In this case, there is no need to adhere to a special order, the overall pattern should turn out to be abstract (see figure).

In the valley area, ordinary tiles are mounted on top of the valley carpet on two roof slopes (see figure). Each shingle suitable for the valley is additionally secured in the upper part with roofing nails (2) at a distance of at least 30 cm from the axis of the valley (1). Then, using laces, beat off two lines (3). The ordinary tiles are cut along these lines, having first placed a board under them so as not to damage the valley carpet. The upper corners of the shingles approaching line 3 are trimmed to remove water (4). On the lower side, in places where there is no adhesive layer, the bitumen roof is coated 10 cm from the cutting line with TechnoNIKOL mastic (5).

The width of the valley gutter depends on the location of the building and the size of the water flow from the roof slopes; it can range from 5 to 15 cm. If the building is located among trees (for example, in a forest), then the gutter is made wider to facilitate the removal of leaves. When the water flow from the slopes is significantly different, to prevent water from washing away the roofing material, the valley gutter is shifted towards a smaller water flow.

Undercut method

When installing a valley using the “cutting” method, first the shingles and levels are laid on a slope that has a smaller slope angle (see figure). In this case, sheets of ordinary tiles must extend onto the steeper slope by at least 30 cm. In the upper part, each shingle is additionally secured with roofing nails (2) at a distance of at least 30 cm from the axis of the valley (1). When the slope with a smaller slope is completely covered, tiles are laid on the second slope. On a steeper roof slope, at a distance of 7-8 cm from the valley axis, mark a line (3). Along this line, sheets approaching the valley from a steeper slope are cut (it is recommended to adjust a board under it so as not to damage the underlying material). Top corners the outermost shingles are trimmed to remove water (4). On the bottom side, in places where there is no adhesive layer, these shingles are coated to a width of 10 cm with TechnoNIKOL bitumen mastic (5).

6. Arrangement of ribs of slopes and skates

Method No. 1

When using this method ridge-eaves tiles are used. It is first divided into three parts by perforation. Ridge-eaves tiles are used when installing “Accord”, “Sonata”, “Dragon Tooth”.

Edge. The shingles facing the edge are cut so that there is a gap of 0.5 cm wide between the tiles from adjacent slopes. Using laces, two approximate lines are beaten along the edge. Lay flexible tiles on the edge in the direction from bottom to top. The elements are mounted with an overlap, the overlaps should be 3-5 cm wide. The Euromet company recommends securing each shingle with four nails (2 on each side) so that the top one covers the fasteners of the underlying one.

Horse. The soft roofing on the ridge begins to be laid on the side opposite to the direction of the prevailing winds in the area. Its installation is carried out similarly to the installation of tiles on the edges of the roof.

Method No. 2

When using Shinglas flexible tiles with cutting shapes “Trio”, “Sonata”, “Dragon Tooth”, “Beaver Tail”, elements for covering the ridge and ribs can be cut from shingles of ordinary tiles. For the "Sonata" cut shape, it will be visible top part, and the one being closed is the lower one (see fig.)

On the underside, in places where there is no adhesive layer, the elements are coated with TechnoNIKOL mastic before installation. Covering the ridges and ribs with patterns from ordinary tiles is carried out in the same way as with ridge-eaves tiles.

Important: When installing soft roofing Shinglas series " ", " ", " ", " " in conditions of low (up to +5°C) temperatures, it is recommended to bend the elements to warm pipe about 10 cm in diameter. This will prevent them from cracking.

7. Installation of SHINGLAS flexible tiles on curved surfaces (domes, cones)

On the roofs non-standard shape Shinglas flexible tiles can be laid in two ways - segmental and seamless. When using any of them, an underlayment must first be laid.

Installation of Shinglas on a dome or cone surface using a segmental method involves dividing it into segments. The size of the segments depends on the size and shape of the surface to be covered. The lines are broken off using laces. Row tiles are mounted on each segment, and ridge tiles are installed at the joints between them (similar to the ridge and ribs of the roof). The width of the ridge tiles must also correspond to the dimensions of the surface to be covered.

1) Metal tip (installed after installing the shingles);
2) vertical trim lines (slope marking);
3) a whole petal of tiles;
4) 1/2 petal of tile;
5) ANDEREP underlay carpet.

When laying tiles using the seamless method, special attention must be paid to marking the surface (see figure). First, marks are made with chalk on its base in increments, equal to half petal of the tile used. From these marks on the backing carpet (5), lines are drawn to the top of the surface to be covered (the lines are connected at the top). Ordinary tiles cut into separate petals, from which the first row is assembled. The next row is shifted by half a petal relative to the previous row. The material for it is cut in accordance with the marked marking lines (2). When the width of the trimmed elements becomes half the original (4), whole tile petals (3) begin to be used again for the next row. In this order, the roof is laid to the top of the surface. The top is decorated with a metal tip (1).

8. Connection device

To bend the materials more smoothly, a triangular shaped strip is nailed at the junction of the wall and the roof slope (see figure). It can be made from a wooden beam cut diagonally with a cross-section of 50x50 mm or use an ordinary wooden plinth. If the wall adjacent to the roof is brick, it is pre-plastered and primed. The shingles of ordinary tiles suitable for the abutment are placed on a nailed strip. Strips with a width of at least 50 cm are cut out of the TechnoNIKOL valley carpet. On the bottom side, they are treated with TechnoNIKOL bitumen mastic over the entire surface and laid on top of the tiles. The valley carpet strips are positioned so that they extend onto the wall by at least 30 cm (and in regions with large snow loads higher). The upper edge of the junction material is inserted into the groove and pressed with a metal apron. The structure is fixed mechanically and sealed using polyurethane, thiokol or silicone sealant.

The method of sealing the junction of the roofing with ventilation pipes and chimneys is shown in the figure. From a valley carpet or metal sheet Patterns are made with an anti-corrosion coating, they are cut and bent in the indicated places. First, install the face pattern on top of the regular shingles that fit the pipe. Then the side and lastly the back patterns are laid. They are placed under shingles of material. A gutter 80 mm wide is made on the back and sides. The upper corners of the soft roof shingles that fit the pipe are cut to allow water to drain away. The underside of these shingles, in places where there is no adhesive layer, is coated with TechnoNIKOL bitumen mastic to a width of 10 cm.

If the cross-section of the pipe is larger than 50x50 cm, and it is located across the roof slope, a groove is made behind the pipe (see figure). This will prevent excessive snow accumulation behind the pipe.

If the bottom of the roof slope is adjacent to the wall, a metal storm barrier is installed at the end of it (see figure).

9. Pass-through elements

For sealing places where communication pipes, antennas, etc. pass through the roof. use special passage elements (see figure). The passage element is secured mechanically (with nail connections). The shingles of ordinary bitumen tiles are laid on it, they are cut and fixed to the flange with TechnoNIKOL No. 23 FIXER mastic. A suitable roof outlet is then installed on the penetration element.

TechnoNIKOL roof ventilation elements are available in non-insulated and insulated types (see figure). They are part of room ventilation and sewerage systems. The use of polyurethane-insulated ventilation outlets is advisable in areas with long, frosty winters, since condensation does not freeze inside them. It is not recommended to install caps on sewer roof outlets, as condensation accumulates in them. If it freezes, it will prevent normal ventilation.

For a more aesthetically pleasing appearance of the roof outlet, you can install a cap on it without internal cuts (see figure). In addition to its decorative function, it helps prevent precipitation and leaves from entering the pipe.

Roof care

  1. In spring and autumn, it is necessary to inspect the roof to check its condition and timely identify defects.
  2. It is recommended to remove leaves and small debris from the roofing with a soft-bristled brush. Do not use sharp tools, as this may damage the tiles.
  3. Objects with sharp edges are removed from the roof by hand.
  4. Drains, gutters and pipes should be checked periodically and, if necessary, cleared of debris.
  5. If a large amount of snow accumulates on the roof, it is removed layer by layer with a non-sharp shovel. At the same time, a layer of snow approximately 10 cm thick is left to protect the roofing.
  6. From time to time, Euromet specialists recommend checking the condition (and, if necessary, repairing) metal parts, mounting holes, openings and other elements located on the roof.

Roof repair from flexible Shinglas tiles

SHINGLAS bituminous shingles are a repairable roofing material. If there are minor defects in the roofing covering, local repairs can be carried out independently. It is important to identify and, if possible, eliminate the causes of material damage. This could be, for example, installation errors, abrasions from nearby tree branches, the presence of depressions in which water stagnates, etc.

Repair procedure:

  1. Eliminating the cause of damage to the roofing.
  2. Dismantling damaged material.
  3. Laying new roofing material. The joints between the new upholstery and the main coating are heated using a heat (construction) hair dryer.

Installation work is carried out in stages, in several steps, each of which is fundamentally important for the quality of the entire roofing system.

Preparatory work

No matter how reliable the soft roof covering is, the roof can “move” or leak if the fastening is done without competent preparation. Therefore, preliminary work before laying the roof is very important and should be carried out by professionals in several stages.

Creating a rafter system

The rafters bear the main load from flexible tiles, so you need to make the correct calculation taking into account the weight roofing pie, wind and snow exposure.

Advice. Securely fasten the rafter legs, process wooden elements special protective equipment to improve the reliability of the design.

Vapor barrier device

After installing the rafters, it is necessary to lay a vapor barrier film that will protect the roofing pie and insulation from condensation. The film is laid overlapping, and the resulting seams are taped.

Insulation

In order for the thermal insulation to hold securely, between rafter legs you need to nail a block that will hold the insulation boards. Thermal engineering calculations will help you choose the correct insulation thickness. Thermal insulation boards are laid staggered and covered with a wind and moisture protective film, which is secured with a counter beam.

Advice. The counter beam must be nailed parallel to the rafters to create a free ventilation channel to remove excess moisture from the under-roof space.

Installation of bituminous shingles should only be carried out on a flat, solid base, for which it is preferable to use sheathing and solid flooring made of moisture-resistant plywood or OSB. The boards are fixed with special galvanized nails.

After laying the base, preparation for the installation of a soft roof is completed - you can begin the main work.

Installation of bitumen roofing: materials used

When installing flexible bituminous shingles, we recommend using high-quality materials of the IKOPAL brand, which are produced in accordance with European standards and certified according to Russian standards. To install a soft roof, you will need the following materials.

Roof covering includes:

  • SBS-modified with a fiberglass base with colored slate coating on the top side;
  • ridge-cornice strip of similar composition for arranging cornices, ridges, ribs;
  • valley carpet - roll protective material, which is used to strengthen soft fused roofing in valleys and other vulnerable places;
  • underlayment carpet is a roll of waterproofing, the installation of which is an obligatory step in the roofing installation work.

Advice. The underlayment carpet is laid over the entire surface of the roof from bottom to top, parallel to the eaves overhang. Avoid wrinkles!

Additional components/materials

  • Metal abutment strips, gable strips, and drip edges are needed to remove moisture from the edges of the roof and give it a complete appearance.
  • Fastening bitumen shingles is impossible without special galvanized nails with a head size of 8 mm or more.
  • IKOPAL mastic and adhesive-sealant are used to seal joints, overlaps, and other joints and seams.
  • Elements such as deflectors, under-roof fans or pipe flanges ensure that ventilation systems are brought to the roof.
  • The IKOPAL drainage system, including gutters, brackets, funnels, elbows, and fastenings, allows you to effectively drain external water.

Vapor barrier

The instructions for installing the roof indicate the need to create a reliable vapor barrier layer. As a vapor barrier, it is worth using a durable four-layer reinforced IKOPAL Polycraft membrane, which not only protects against condensation, but also effectively reflects heat, reducing energy costs.

Advice. Lay the vapor barrier with an overlap of 100-150 mm and seal with double-sided tape.

Thermal insulation

Installation of bitumen shingles involves the use of such thermal insulation material as non-flammable mineral wool density from 30 kg/m3.

Windproof membranes

ICOPAL Monarperm hydro-windproof membranes, which are laid on top of the thermal insulation without a ventilated gap, help protect the insulation from wind and water.

Do not try to save on materials for bitumen roofing, as this will lead to deterioration in quality and a reduction in the service life of the roofing covering.

Laying roofing material: installation instructions

The preparatory measures have been carried out, the base for the roof is ready - which means you can proceed directly to the installation of flexible tiles.

1. Install the underlay carpet

First, we lay a special waterproofing layer on the finished, level base - IKOPAL K-EL or Felix underlay carpet. We unfold it from bottom to top parallel to the eaves overhang, fix it to the base along the top edge every 40 cm, along the bottom every 10 cm. We seal the overlaps with mastic.

2. Install the planks

We nail the cornice and end strips onto the underlayment using roofing nails in a zigzag pattern. The overlap is 3-5 cm, the pitch between nails is 10 cm.

3. Install the cornice strip

We remove the strip from the ridge-eaves protective film, we retreat from the bend of the cornice strip 10-20 mm, fix the strip joint to joint. In places of perforations and along the edges we nail.

4. Install the valley carpet

The carpet to protect the valley is installed in two layers: the top one matches the color of the main covering, and an additional layer of lining carpet is used as the bottom one. It is fastened with nails in increments of 20 cm. The valley carpet is laid in the direction of the valley axis with the edges fixed every 10 cm.

Advice. To avoid damaging the valley carpet when cutting flexible tiles, a plywood sheet should be placed under it.

5. Installing ordinary bitumen shingles

To avoid visual defects when installing a soft roof, it is recommended to mix the shingles from four or six packs to balance the shade before installation. After this, you can proceed directly to covering the roof with bitumen shingles.

The installation of the roof begins from the middle of the eaves overhang and moves towards the ends. To lay the first row, we retreat 1 cm from the lower edge of the eaves flexible tiles and on this line we fasten the lower edge of the row petals, having first removed the lower protective film from the shingles. Fastening is done with four or six (at a large slope) nails per shingle.

Advice. When using rectangular shingles, the number of nails should be increased to 5 on flat roofs and to 7 on slopes greater than 45 degrees.

During further installation of row tiles, we make sure that the petals of each subsequent row coincide with the cutouts of the previous one. In the area of ​​the ends, we cut the shingles along the edges, glue them to the end strip with mastic, and seal the seams with the appropriate adhesive.

Installation of tiles in hard-to-reach places

The installation of soft roofing in areas adjacent to a wall or chimney, in the area of ​​openings for laying pipes, communications, and on the roof ridge requires special attention and control. Failure to comply with installation technology in these places can damage the tightness and appearance coverings.

The main rule when constructing installation passages or installing a soft roof on lifting strips when installing chimneys is to fix the shingles with bitumen mastic and be sure to seal the seams with IKOPAL adhesive-sealant.

To install ridge tiles, use ICOPAL Combi ridge-eaves strip tiles measuring 25 by 33 cm. The instructions require that ordinary shingles be brought to the level where their fastening points will be covered by ridge tiles. The latter is laid parallel to the ridge, bending over the slope, then fixed with two nails on each side.

The overlap when laying ridge tiles should be 5-10 cm and cover the fastenings of each previous element. The final tile is fixed with mastic.

Advice. It is not difficult to divide the IKOPAL ridge-cornice strip into separate tiles: just break it into three parts in places with perforations.

Summary

Step-by-step instructions for installing flexible tiles will allow you to create a reliable, durable, beautiful roofing covering that will protect the building from leaks and atmospheric influences for a long time.

The correct installation technology, together with the use of high-quality materials from the manufacturer ICOPAL, will ensure long-term preservation of the operational and aesthetic characteristics of the roof.

Soft roofing is a term that combines a number of flexible roofing materials with excellent consumer qualities. Its piece and roll varieties perfectly protect the house from atmospheric “misfortunes” and effectively decorate the exterior. They weigh little, do not require effort in cutting and fastening. Among the advantages is the ability to lay the coating yourself.

For an ideal result, it is not necessary to have the skills of a roofer. You need skill, patience, tools and information about how the technology of laying a soft roof differs from other methods and how to properly install a roof.

Materials from the group of soft roofing coverings are modified versions of the good old roofing felt. The new developments borrow from their predecessor flexibility and lightness, which rightfully top the list of advantages. They have retained unshakable water-repellent properties, thanks to which the wooden base and rafter system last longer. The composition has been improved, due to which the period of flawless operation of the materials has increased threefold.

Based on the installation method, the class of soft roofing coverings is divided into three types:

  • Roll materials, supplied in the format corresponding to the name. These include bituminous descendants of roofing felt and new representatives, such as polymer membranes. Roll coverings are laid in strips. Bituminous materials are attached by fusing, polymer materials by partial or complete gluing. With their help, they are mainly used to equip flat and gently sloping roofs with slopes up to 3º, permissible up to 9º. Rolls are in demand for the most part in industrial construction;
  • Roofing mastics, supplied ready-made or cold to be reheated. Sprayed or applied in a thick layer on flat roofs, resulting in a monolithic coating without seams. Reinforcing mesh is used for strengthening. The scope of application is limited to flat roofs.
  • Bituminous shingles, supplied in flexible shingle tiles. Essentially, it is an improved roofing felt material, cut into relatively small sheets. The edge of the shingles is decorated with figured petals to imitate the ceramic prototype. The back side is equipped with an adhesive strip for attaching to wooden base. Glued individually. Additionally, roofing nails or self-tapping screws are driven into each shingle. When a bitumen roof is heated by the sun's rays, the tiles are sintered and transformed into a continuous roofing shell.

In private low-rise construction, the piece variety is actively in demand, because Flat and low-pitched roofs over one- or two-story residential buildings are constructed extremely rarely. Domestic buildings have a “flat” fate, but not every owner will decide to buy membranes and mastics for the roof of a barn. This means that we will pay attention to the installation of the most popular bitumen shingles.

Step-by-step installation of bitumen shingles

Roofs with any slope and degree of architectural complexity are covered with piece flexible material. True, bitumen shingles are not recommended for roofing if the slope angle is less than 11.3º. The material is produced by numerous manufacturers. Each of them strives to provide their own products with unique qualities and properties beneficial to the installer.

Despite some differences, the technology for installing a soft roof follows the same scheme. There are small nuances, but they are not important.


Rules for preparing the base

Flexibility is an advantage and disadvantage of bitumen coating. On the one hand, it allows you to significantly speed up the process. After all, it takes a little time and a minimum of effort to form junctions, drill pipes, and arrange valleys and cornices. On the other hand, due to the flexibility of the material, a continuous sheathing is required so that the bending shingles rest entirely on a solid, level base.

You can build a continuous sheathing before installing a soft roof:

  • from OSB-3 boards, recommended based on budget cost and sufficient strength;
  • from sheets of moisture-resistant plywood marked FSF;
  • from tongue-and-groove or edged boards, the humidity of which should not be less than 20%.

Sheet material is laid in a staggered pattern brickwork. It is important that there are no cross-shaped joints. It is necessary that the weak areas where the slabs join are evenly distributed over the counter-lattice. Gaps of 2-3 mm should be left in the seams, which are required for the free movement of the rafter system during temperature fluctuations.

The boardwalk is installed parallel to the roof overhangs. Also take a running start if the length of the board is not enough for the slope. The place where two boards meet on the slope should be supported by a counter-lattice beam, and four nails should be driven into it. Ordinary boards are secured with two nails on both sides. They must be laid so that there is a gap of 3-5mm between the longitudinal elements. Before work, edged boards are sorted. Those that are thicker should be distributed at the base of the slope, those that are lighter should be sent upstairs.

Ventilation is the key to impeccable service

The excellent water-repellent properties of the bitumen coating are due to the tiny number of pores that can allow moisture and air to pass through. A reliable hydro-barrier works in both directions. Inside roofing structure Raindrops do not penetrate, but steam does not escape. If vapors do not have a clear path, condensation will accumulate on wooden roof trusses and sheathing. Those. a fungus will develop, because of which you will have to say goodbye to a durable roof.

For the sake of long-term, impeccable service, it is necessary to establish a system roof ventilation, including:

  • vents designed for air flow in the eaves area. In addition to the influx, they must ensure the free movement of air from bottom to top along the planes of the slopes. The products are open channels, formed by lathing and counter-lattice;
  • ventilation gap between bitumen roofing and insulation laid on top of the vapor barrier. Designed for washing the insulation with air flow;
  • holes in the upper zone of the roofing pie. These can be either the ends of the slopes that are not closed at the top, or specially designed vents with a plastic trunk that resembles a miniature chimney pipe.

Ventilation must be arranged in such a way as to prevent the formation of air pockets in the under-roof space.

Laying insulating carpet

Without exception, all manufacturers of asphalt shingles strongly recommend laying an additional waterproofing carpet before installing shingles. The list of materials suitable for carpet is usually indicated in the instructions. The products specified or similar in characteristics are approved for use.

Replacement is highly undesirable, because a composition incompatible with the coating will prevent the bitumen layers from joining into a monolith and will contribute to swelling. Polyethylene excluded. Ruberoid too, because the service life of a flexible roof is longer. It is unreasonable to lay less durable material under a coating designed for 15-30 years of operation.

The technology for laying an insulating carpet under flexible tiles includes two options, depending on the steepness of the roof:

  • Installation of a continuous carpet on pitched roofs with an angle of inclination from 11.3º/12º to 18º. Roll waterproofing laid in strips, starting from the overhang, moving towards the ridge. Each strip laid on top must overlap the previous strip with its own ten cm. If it is necessary to join two sections in one row, they are laid with an overlap of 15 cm. The overlap is carefully, but without fanaticism, coated with bitumen mastic. The insulation strips are attached to the base with roofing nails every 20-25cm. Strips of barrier water-repellent protection are laid on top of the continuous carpet in valleys and overhangs, as well as around roof junctions. Then the ridge and convex corners of the roof are equipped with the original insulating material;
  • Laying partial insulation on pitched roofs with a slope of 18º or more. In this case, the valleys and overhangs are protected with bitumen-polymer material, and only the edges of the gables, ridge and other convex corners are covered with strips of insulating carpet. Insulation, as in the previous case, is used to border the intersections of the roof with communication pipes and roof junctions. The width of the bitumen-polymer barrier along the overhangs is 50 cm, in the valleys it is 1 m, so that each of the protected slopes has 50 cm. When laying around junctions and pipes, the insulating strip is partially placed on the walls so that the material covers 20-30 cm of the vertical surface.

The installation of a flexible roof with partial waterproofing is allowed by manufacturers, but there are no ardent supporters of this method among them. Naturally, on steep slopes less precipitation is retained, but the circumstances are different: ice, slanting rain, etc. It's better to play it safe.


The bitumen-polymer carpet for valleys is selected to match the tiles. A slight deviation from the color of the coating is allowed if there is a desire to emphasize the lines of open grooves. It is advisable that the valleys be covered with a continuous strip of barrier insulation. But if joining of two pieces cannot be avoided, it is better to arrange it in the upper part of the roof with an overlap of 15-20 cm. There is the least load. The overlap must be coated with bitumen mastic.

Protection of gables and eaves

The perimeter of the roof is equipped with metal strips. They are needed to protect weakened areas of the sheathing from moisture and as roof design elements. The planks are laid edgewise on the edge of gables and overhangs. The edge line should coincide with the roof outline line. Fasten with roofing nails in a zigzag pattern every 10-15 cm.

If there is a need to join two planks, they are laid with an overlap of 3-5 cm, at least 2 cm. The pediment planks overlap the eaves at the corners of the roof. In places of end and joining overlaps, fasteners are hammered in after 2-3 cm.

Most flexible roofing manufacturers recommend installing both types metal protection over the underlay carpet. However, the developers of the Shinglas brand recommend placing cornice strips under the carpet, and pediment strips on top of it. Before installing gable and cornice strips on the plank sheathing, they also advise first nailing the block and then attaching metal protection to it.

Formation of passages through the roof

Chimneys crossing the roof, communication risers, antennas, own ventilation holes need special arrangement. They create a potential hazard in the form of an open path for water leaks. Therefore, before installing the covering, the roof penetration areas are covered with sealing devices or systems. Among them:

  • Rubber seals designed to cover small diameter points. Holes for antenna, for example;
  • Polymer passage elements used to equip roof intersections with sewer and ventilation risers. They are produced specifically for arranging roofs. The passages are simply attached with nails to the continuous sheathing. Bitumen shingles are laid on top, which are actually trimmed around the passage and fixed with bitumen mastic;
  • Plastic adapters for your own roof ventilation. The holes are closed with vents, a ridge element with channels for removing fumes, and perforated devices for cornices.

Rules for arranging large passages chimneys worth considering separately. In addition to the threat of leaks, they are also a fire hazard. Chimneys are sealed in several stages:

  • the walls of the pipe are protected with parts cut from asbestos-cement slabs according to its actual dimensions;
  • A triangular strip treated with a fire retardant is installed around the perimeter of the pipe. To make it, you can split the block diagonally. A baseboard is suitable for replacement. The chimney plank is not attached to the sheathing! It must be fixed on the walls of the pipe;
  • lay flexible tiles, placing the shingles on the strip;
  • parts are cut out from the valley carpet according to the dimensions of the pipe with set bar. The width of the parts is at least 50 cm. The patterns are attached with a 30-centimeter overlap to the pipe walls using glue or bitumen mastic. First, glue the front part, then the sides, and finally the back. The lower edge is placed on top of the laid tiles, the upper edge is inserted into a groove on the pipe wall;
  • Finally, the multilayer insulation system is secured by installing a metal apron and treating the joints with silicone sealant.

There is a simpler and cheap way: the parts of the insulating lining of the pipe are cut not from carpet, but directly from galvanized metal. Then half of the work steps will disappear by themselves.


Wall connections sealed using a similar method. Only there is no need to install asbestos-cement protection, and the protected surfaces must be plastered and treated with a primer before installation.


Rules for laying eaves shingles

In order to create guidelines for the installer, it is better to first mark the roof with coated construction lace. Horizontal lines are applied in increments equal to five rows of flexible tiles. Verticals are struck in increments of one shingle.

After preparing and marking the roofing surface, you can safely begin laying flexible tiles, following the algorithm:

  • The first to be installed is the cornice row of tiles on the overhang. You can take a special ridge-eaves tile or cut out the starting element yourself by trimming the petals of ordinary ordinary tiles. You need to step back 0.8-1 cm from the edge of the metal cornice strip and glue the cornice shingles. For gluing, you need to remove the protective tape from the adhesive layer and coat the remaining areas with mastic;
  • the laid eaves tiles are secured with roofing nails in increments equal to the width of the petal. When driving in, the wide head of the hardware must be strictly parallel to the surface of the continuous sheathing. Distortions are unacceptable. Hammer the nails at a distance of 2-3cm from the top edge of the shingles. The fixation points must overlap the next row of roofing;
  • The first row of flexible tiles is laid. It’s better to start from the center of the slope to make it easier to align horizontally. You should retreat 1-2cm from the bottom line of the starting row and glue it using the already proven method. Nail with four nails at a distance of 2-3cm from the groove between the petals;
  • It’s also more convenient to start installing the second row from the middle. But the shingles must be moved so that the tab is above the groove of the first row of shingles and the attachment points are completely covered;
  • The upper corner of the tiles laid next to the pediment is cut in the form of an equilateral triangle with sides of 1.5-2 cm. pruning is needed to remove water.

You can continue laying shingles according to the linear principle, i.e. laying down a whole row, one after another. You can use the pyramidal method with “building up” from the middle of the slope to the edges or diagonally.

Two ways to construct a valley

Two methods have been developed to form a valley:

  • Open gutter device. Row tiles are laid to the valley axis on both adjacent slopes. Only the nails stop driving at a distance of 30cm from the axis. After laying the coated cord, valley lines are marked on the slopes, along which the coating is carefully trimmed. The width of the valley is from 5 to 15 cm. To prevent damage to the soft roof during cutting, a board is placed under the tiles. The corners of the tiles located near the valley are trimmed to remove water, then the back side of the covering elements is coated with mastic and glued.
  • Closed gutter device. The tiles are laid first on the slope with the smallest slope so that approximately 30 cm of material is located on the adjacent slope. The shingles are secured at the top with nails. Afterwards, the second slope is covered, then a line is beaten on it, 3-5 cm away from the axis, along which cutting is carried out. The corners of the tiles are cut to remove water, and then the cut loose elements are glued to the mastic.

The nuances of laying tiles on a ridge

Upon completion of the installation of the tiles on the slopes, they begin to arrange the ridge. Ventilation ducts the body of the sheathing must be left open, so a gap of 0.5-2 cm is left between the tops of the slopes. To ensure ventilation, the ridge is equipped with a plastic aerator. It is not very attractive, so for the sake of aesthetics it is decorated with universal ridge-eaves tiles or shingles cut from shingles.

Nail the tiles with 4 nails. Each subsequent element must cover the fasteners of the previous one. The tiles are mounted on the ridges from bottom to top. The ridge is arranged in the direction of the prevailing winds so that open areas turned to leeward.

In detail the process of installing a soft roof with explanations step-by-step technology The video will demonstrate the styling:


No particular difficulties were found in the construction of a soft roof. There are technological features. If you strictly follow them, you can easily do the installation yourself with excellent results.

The service life of a house largely depends on the strength and reliability of the roof, and this is achieved by using high-quality roofing materials. One of these materials is bituminous shingles, and today I will tell you how to install flexible tiles with your own hands, in accordance with the technology, and I will introduce you to some of the nuances of this process.

Preparatory stage: calculation of materials

  • Calculation of flexible tiles is made based on the roof surface area, plus a margin of 10%, since during operation, material waste ranges from 3 to 7%.
  • Mastic is purchased based on use:
    • valleys – 200 g/m;
    • ends – 100 g/m;
    • junction nodes – 750g/m.
  • Roofing nails with galvanic coating - 80 grams per 1 sq. m. (9 mm cap, length 3 cm, 3 mm diameter of the rod).

To install a roof made of bitumen shingles you will also need:

  • Steam and waterproofing membranes;
  • thermal insulation material (mineral wool, extruded polystyrene foam or other type of insulation);
  • Double-sided tape;
  • material for constructing a base for bitumen shingles (chipboard, OSB-3, FSF, board);
  • wooden beams for counter-lattice.
  • lining carpet.

Material consumption is calculated based on the roof area, plus a 10% margin.

Important! Rafter system must be strong, since the weight of the soft roof pie is quite large.

Having prepared everything you need, you can proceed to the stage of installing the base and actually installing the roof from bitumen tiles.

Preparing the base

The technology for installing flexible bitumen shingles involves several stages, which are performed in a certain sequence.


Important! Before starting work, all wooden structural elements must be treated with an antiseptic to prevent damage, fungus or mold, and insects.

After the base for the flexible tiles is ready, you can proceed to laying the lining carpet under the bituminous shingles.

The nuances of working with underlay carpet

At this step, it is important to take into account the angle of inclination of the roof - the installation technique and required amount lining carpet:

  • When the slope of the roof slopes is 12–18 degrees, the lining carpet is installed as a continuous sheet.
  • If the roof slope is over 18 degrees, only the overhangs of the eaves, valleys, and slope junctions can be covered with lining material, but it is still recommended to make a continuous carpet over the entire roof.

First, the valleys are covered, then the strips of material are laid in two ways:

  • horizontally, starting from the bottom and rising to the ridge of the roof - by blocking the bottom strip, the top one prevents moisture from flowing in;
  • vertically - the carpet is rolled out from top to bottom. Fastening is done with nails on the ridge, then the material is stretched and fastened in the overhang area.

The overlap of the hydrobarrier strips should be 15 cm to the sides and 10 cm in length. The joints are additionally coated with bitumen mastic (if there is no special adhesive layer on the roll), and also fixed with nails in increments of 25 cm.

Important! The mastic must be applied thin layer, no more than 1 mm. If it is necessary to dilute the bitumen mastic, you must not overdo it with the solvent - neglecting this requirement risks causing the bitumen coating to swell.

Installation of cornice strips

Laying of cornice and end strips is carried out to prevent deformation of the material under the influence of temperature changes and protection wooden structures from unfavorable environmental factors.

Metal cornice strips are installed with an overlap of 5 cm, and fastened with nails or screws in a checkerboard pattern in increments of 10–15 cm. The joints are fixed with two screws or nails.

At the ends, the planks are fastened in the same way.

Since shingles have small sizes, during installation, the rows of tiles may be laid unevenly. To eliminate this possibility, preliminary markings are made on the roof surface.

  • Along the edges of the roof from top to bottom, using a level, two vertical straight lines are drawn with chalk or a marker;
  • then, perpendicular to them, longitudinal straight lines are drawn in increments of 25 cm.

Arrangement of the valley

When the lining carpet is ready and the end strips are installed, the valleys are covered with a special valley carpet, which is selected in accordance with the color of the tiles. The carpet is fixed using bitumen mastic, which is distributed along the perimeter of the carpet. The width of the mastic layer is 10-15 cm. Additionally, the valley carpet is fixed with roofing nails in increments of 15 cm. This process is covered in detail in the video below:

Finishing the valley should begin with the slope that has the shallowest angle, or with a slope with a shorter length. On the carpet, parallel to the valley axis, it is necessary to draw or mark two lines:

  • the first at a distance of 5-7cm - this will be the so-called gutter line along which the shingles will be cut;
  • The second is at a distance of 30 cm from the axis - the last nail will be driven along this line, that is, you cannot mechanically fasten the tiles closer than 30 cm to the axis of the valley.

The shingles that extend to the first line are trimmed, and their top edges are trimmed at a 45-degree angle. Mastic is applied to the tiles and valley, after which they are pressed against each other. The second line is used for fastening with nails.

For roofs with a pitch of less than 45 degrees, one shingle is nailed with five nails. When the slope angle is more than 45 degrees, fastening should be done with at least 8 nails.

Technology for laying eaves and row tiles

According to the technology of laying flexible tiles, it is necessary to start the installation process from the bottom of the slope (with a distance of 2-3 cm from it). The first row can be laid in two ways:

  • using special eaves tiles;
  • in the absence of one, the petals are cut off from ordinary shingles, and the resulting strips are used as cornice elements.

The strip is fastened with nails (the distance from the edge must be at least 25 mm, as in the photo above), or, if installation is carried out in cold weather, the shingles are heated construction hairdryer and glued to the cornice strip.

Arrangement of junctions to pipes

For connecting the soft roof to brick pipe There are several ways. The first is to install a metal apron that matches the material and color of the shingles. Special kits are available for sale that include everything needed for installation.

The second is to use pieces of valley carpet, from which the lower, side and upper elements connecting to the pipe are cut out.

First, a plinth or triangular block is placed at the base of the pipe, on top of which a lining carpet is laid. The pipe itself is plastered and treated with a bitumen primer.

The connection device occurs parallel to the installation of ordinary flexible tiles:

  • The shingle adjacent to the bottom of the pipe is cut along a triangular strip and attached to the base;
  • Next, first the lower abutment element, cut from the valley carpet, is installed, then the side and upper elements. They are coated with mastic and glued to the pipe (to a height of at least 30 cm) and the lining carpet (with an overlap of at least 20 cm);
  • a groove is cut out of the brick into which a metal junction strip (apron) is inserted. Its fastening to the pipe is carried out mechanically, using nails, dowels or screws, and the joint is sealed with polyurethane sealant;
  • the remaining ordinary shingles of flexible tiles are laid on top of the abutment element, glued to it with mastic, and additionally secured with nails.

This whole process is illustrated in detail in the video:

If it is necessary to install ventilation or aerators, seal round holes performed according to the illustration below:

Laying ridge elements

The roof ridge made of flexible tiles is made using ridge elements. The sequence of actions is as follows:


If additional ventilation is needed, a plastic ridge aerator can be installed on the ridge. It is attached to the roof with long nails, and covered with tiles on top.

In conclusion, I suggest you watch a video where absolutely all the steps in the installation technology of flexible tiles are discussed in detail:
