If you are calculating ondulin for a roof, then it is very important to do everything correctly. You don’t need extra material, just as you don’t want a situation where a couple of sheets are missing and because of them you need to stop work and go to the store. Therefore, carefully study all the recommendations from the review to eliminate any inaccuracies and implement calculation work quickly and correctly.
What you need to know
First, we will deal with the main material, and then we will move on to additional elements, since without them it is impossible to build a strong and durable roof. In fact, there is nothing complicated about this issue, and you will figure it out in literally 10 minutes; this is the great advantage of this roofing over other options.
Before you start calculating, you should know several important indicators:
- Roof area. You need to measure the length and width of each slope. The work is carried out using a long tape measure, all data must be recorded so as not to confuse anything and ensure the accuracy of all indicators;
- Ridge joint length. If there are several of them, measure each section separately;
- Roof end dimensions. You must determine the exact size of each edge of the slope;
- Length of valley joints if available;
- Additional items- chimney pipes, ventilation outlets, etc.
Ondulin sizes
Not bad specifications ondulin are determined by its structure. The sheets consist of cellulose fibers impregnated with modified bitumen, which contains special additives that provide high strength and color retention over a long period of time.
Let's figure out the sizes. Ondulin (its second name is Euroslate) is sold in sheets that have the following parameters:
| Illustration | Description |
 |
The length of the sheet is 2 meters. This is a complete indicator; if you need to calculate the useful length, then it is worth remembering the following:
Based on this, effective area will be 1.29, 1.54 and 1.56 square meters. m. respectively. |
 |
Sheet width is 950 mm. It is also standard, which significantly simplifies the calculation work. Naturally, there is also an overlap at the side joints, so if you need working width, then remember two simple nuances:
|
 |
Wave height 36 mm. This is exactly the indicator that the original ondulin should have. If you are offered another option, then most likely it is some kind of analogue with low quality. |
 |
Thickness is 3mm. This indicator does not affect the calculations, but the strength of the roof directly depends on it. Therefore, be sure to make sure that the thickness corresponds to the regulatory indicator. Another indicator of the quality of the product is its weight, it should be approximately 6 kg.
|
 |
Actual figures may vary slightly from those stated..
To make it easier for you to understand the size of the tolerances, there is a table on the left. It contains all possible deviations that may occur and comply with the manufacturer’s regulations. Exceeding these indicators is not allowed. |
Additional elements
| Illustration | Description |
 |
Ridge elements. They have a special profile that provides reliable protection joints from moisture. The elements are flexible, so they can be easily bent to any roof slope. The standard length of the ridge element is 1000 mm, the useful length is 150 mm less, this is exactly the overlap that the manufacturer recommends to make on joints. Thickness, same as the main one roofing material, is 3 mm. |
 |
Endovy. Necessary for additional protection of slope joints, if there are any on your roof. If there are no such connections on the roof, then these elements will not be needed. As for the dimensions, the length is 1 meter and the thickness is 3 mm. But taking into account the minimum overlap of 150 mm, the useful length is reduced to 850 mm. |
 |
Wind bars, they are also called tong elements. They are placed on the edges of the slopes and close the joint between the ondulin and the rafter structure. The standard length of products is 1100 mm, a standard overlap of 150 mm is made at the joints, so the useful indicator is 950 mm, which is used in calculations. |
 |
Ridge and cornice filler. Special elements are made of foam rubber and have the same profile as ondulin. They are placed under the ridge and along the lower eaves of the roof and serve to protect against moisture and insects. The length of one piece is 85 cm, thickness 25 mm.
|
 |
Nails for ondulin. When installing sheets and additional elements, special fasteners are used. Its difference is that the cap is made to match the color of the roofing; it can be either in the shape of a pyramid, as in the photo, or in the form of a closing lid. The bottom part of the nails has a ribbed surface for better fixation, and a zinc coating of the metal is used to protect against corrosion. |
Conclusion
Now you can calculate it yourself required amount ondulin for the roof and accessories for it. Additionally, watch the video to understand the topic even better. If you still have any questions, write them in the comments under the review.

It is best to correctly calculate the required amount of ondulin for the roof with the help of experienced and qualified roofers. You can do this yourself. To do this, you will need to take into account the dimensions of the material, as well as the parameters of the roof. Also, during installation work you will need a certain amount of fastening material.
Technical characteristics of ondulin
The dimensions of ondulin are regulated by existing GOSTs, which manufacturers adhere to. Maximum deviation from established sizes is no more than 3 mm. Used in production traditional technology, in which cellulose fiber is impregnated with bitumen and pressed at high temperatures.
- Be sure to secure the sheets well. They may not withstand the wind load, and they will simply be torn off the building
- Maximum permissible temperature installation about 30 degrees. Conduct installation work If this temperature range is exceeded, it is prohibited
- The sheet must be laid loosely and fixed without stretching, otherwise waves will appear as a result
- It is worth purchasing products from time-tested companies. The price of ondulin (standard sheet size) will be about 400 rubles. per sheet, nails package (100 pcs.) - 120 rub.
Important! Ondulin can withstand about 100 freeze-thaw cycles. The dimensions of the sheets are specially selected in such a way as to facilitate installation of the product.
Factory products are guaranteed to withstand about 15 years of operation. But high-quality roofing material can last much longer. Therefore, be stingy when choosing soft roof not worth it, relatively small overpayments can increase the service life by 5 or more years.
And one last thing. Well-known manufacturer values its reputation and therefore carefully controls the quality of products for compliance with standards and GOSTs. As a result, all declared sheet sizes must strictly correspond to actual ones. One of the ways to check the quality of the product is to simply take a tape measure and measure the length and width of the sheet; deviations can be 1-2 mm.
Video about installation of ondulin
A master class on installing ondulin and accessories will help you correctly lay this material on the roof.
Ondulin, or Euroslate, is one of the most reliable roofing materials. Let's take a closer look at Euro slate - what it is, what are the advantages of this material. When carrying out calculations, you will need to know the standard size of ondulin: this will make it possible to avoid shortages or surpluses during roofing.
Features of ondulin manufacturing
Let's find out what ondulin consists of, what materials are used in production. Ondulin sheets got their name from the French company Onduline, which owns a patent for these products. Ondulin material consists exclusively of safe and environmentally friendly components, differing favorably in this respect from traditional asbestos-cement slate.
Pure cellulose is used to make the material: petroleum bitumen and ether resins are used to impregnate it. Not so long ago, the Italian-French development “onduville” appeared. Having a composition similar to ondulin, this new material imitates ceramic tiles.
The following operations are used for the production of ondulin:
- Pulp cleaning. Garbage and impurities are removed from its composition. Then the substance is soaked in water with pigments and modifiers diluted in it. The resulting raw material is called “pulp”.
- Pulp processing. The technical characteristics of ondulin provide for processing on a special conveyor, where the material is pressed to a thickness of 3 mm. Having dried and hardened, the pulp acquires a specific waviness.
- Bitumen impregnation. A cellulose base with an area of 1.9 m2 is impregnated with petroleum bitumen.
- Stacking finished material . Shrink film, equipped with a label and accompanying information, is used as packaging.
Sheet size including overlap - useful width
It is very convenient that ondulin is always available in standard sizes. If deviations in the width or length of the corrugated sheets are detected, we can conclude that most likely we are talking about a fake of interrogative quality. Having in hand information about usable size sheet of ondulin, it is quite simple to calculate the final amount of coating.
Standard size of ondulin sheet:
- The working width of the ondulin is 950 mm. A very convenient size for decorating small and medium-sized roofs.
- Length – 2000 mm. The round number makes material calculation very simple.
- Thickness – 3 mm. Small deviations in this parameter are allowed.
- The height of the profile wave is 36 mm.
- The weight of one sheet is 6 kg. One square meter – 4 kg.
- Sheet area – 1.9 m2.
- The useful area of ondulin smart is 1.6 m2. In this case, vertical and horizontal overlaps are taken into account.
Armed with information about total area roof slopes, counting the number of ondulin sheets does not require significant effort. All you need to do is divide the roof area by the usable area of one sheet (1.6). To compensate for circumcision, 15% is added to the amount received. Also, one should not forget about adjusting the size of the ondulin sheet taking into account the overlap: this is affected by the slope angle of the slopes. In this case, the useful width of the ondulin will differ from the working one. When calculating the useful width of an ondulin sheet, the size of the side overlap is subtracted from the standard indicator.
Strengths of ondulin
Initially, the function of ondulin sheets was reduced solely to the implementation quick repair and sealing leaks on slate, tile and metal roofs. In the course of application, practice has shown that Euro slate is quite suitable as an independent roofing material.
The following qualities contributed to this:
- Light weight. Without exaggeration, we can say that ondulin is the most lightweight material for the roof. This allows it to be laid directly on old slate or profiled sheets without dismantling.
- Duration of service. Ondulin roofing can safely withstand up to 100 frosts and defrosts, which allows the manufacturer to provide a 25-year warranty. As practice shows, Euro slate lasts at least 50 years.
- Good strength. The presence of a wavy profile allows the material to have bearing capacity at 650 kg/m2. He's not afraid snow loads up to 300 kg/m2.
- Hydrophobicity. Ondulin does not allow water to pass through and almost does not absorb water, which ensures reliable protection truss structure from getting wet.
- Soundproofing. The surface of Euroslate has noise-absorbing characteristics. On such a roof, rain, hail or strong winds are almost inaudible.
When choosing ondulin as a roofing covering, it is important to take into account the fact that this material is flammable. The manufacturer does not recommend exceeding temperature regime at + 110 degrees, otherwise the sheets will begin to deform. Based on this, Euro slate should not be used in bathhouses, gazebos with barbecues, homes with fireplaces and solid fuel stoves.
Sheet material developed by the French company ONDULINE has been one of the popular materials for roofing for more than half a century. Today, ondulin is produced in many countries of the world, including Russia. Due to the nature of the material manufacturing technology, the color shades of different batches may vary slightly. To ensure an aesthetic appearance of the roof, it is recommended to use roofing material from one batch, having previously accurately calculated the required number of sheets.
Characteristics of ondulin
Ondulin is actively used in construction capital facilities– residential, commercial and industrial buildings, during the construction of light structures – pavilions, kiosks, canopies, gazebos. Due to its light weight, this sheet material is ideal for repairing old roofs: it can be mounted on top of flat, old roof coverings without fear of excess load on the foundation of the structure. The approximate load of the new flooring will be about 3 kg per 1 m2.
The technology for manufacturing the material is quite simple: cellulose fiber is pressed into corrugated sheets, reminiscent of traditional slate in shape. Then the base is impregnated with bitumen, upper layer The material is coated with a layer of mineral pigment and curable resins. The small thickness of ondulin makes it easy to install - the sheets are easy to lift onto the roof, cut, and use for laying on curved surfaces, since the material bends both in the longitudinal and transverse directions. The total area of the standard sheet is 1.9 m2.
The advantages of ondulin include:
- long service life (15 year warranty, real time service – 50 years);
- attractive appearance;
- resistance to moisture and atmospheric influences (squally winds up to 200 km/h, temperatures from -40 to +80°C);
- high noise absorption coefficient;
- simple installation;
- resistance to biological destruction, acids, alkalis, oils;
- ability to withstand loads up to 300 kg/m2.
Ondulin, unlike standard slate, does not contain harmful substances and does not provide negative influence to your health.
Ondulin sizes
On Russian market Ondulin, manufactured under license from a French company, usually goes on sale. The length of a standard sheet is 2000 mm, width – 950 mm, ondulin thickness is 3 mm, wave height – 36 mm. The permissible error may be +10/-3 mm in length, +5/-5 mm in width, +2/-2 mm in wave height.
Each sheet of ondulin has 10 waves with a width of about 95 mm, which must be taken into account when calculating the material for roofing. When installing a horizontal row, it is necessary to overlap one wave wide to ensure the strength and tightness of the flooring. The vertical overlap when laying ondulin on a roof whose slope slope exceeds 15 degrees should be at least 100–150 mm. As a result, the useful area of one sheet element reaches 1.60–1.64 m2.
If ondulin is laid on a roof with a small slope, the lateral overlap of the sheet should be 2 waves, and the vertical overlap should be about 200 mm, which requires a special calculation of the usable area sheet material.
Before purchasing ondulin, it is important to calculate the roof, taking into account the usable area of the sheet material, so that in the future you do not have to purchase additional products from another batch.
Principles for calculating roof coverings
The easiest to calculate are gable roofs with an inclination angle of 15 degrees, each slope of which is a rectangle, and the overlap parameters are standard. In this case, it is necessary to calculate the roof area and divide it by the usable area of one sheet of ondulin - 1.6 m2.
If you need to calculate a complex roof, then you need to divide it into separate planes - rectangles and triangles, calculate the coverage area for each plane separately and sum it up, adding 5% for installation waste.
When calculating roof materials, you should also take into account the presence of windows in the roof plane, the use of elements such as a valley, ridge, covering aprons, eaves gutter, roof ventilation elements and other components roofing system. Their presence and quantity affects the calculation of ondulin sheets.
The need for accurate calculations
Obviously, in comparison with the total area of a standard sheet element, a difference of approximately 0.3 m2 is gained from each sheet of ondulin, and if this is not taken into account, the purchased material may not be enough to install the entire coating.
A competent approach to calculating an ondulin roof, taking into account the dimensions of the sheet elements, will allow you to avoid problems associated with the acquisition and delivery of missing material, which entails not only additional expenses for transport, but also disrupts the work schedule. In addition, a new batch of ondulin may differ in shade from the existing one, which will worsen the overall appearance of the roof.

Ondulin roofing price per sheet dimensions and photos
Roofing Ondulin is in stable demand in more than 100 countries around the world. The reasons for this popularity are: affordable price And universal sizes sheets.
Ondulin “SMART” - reliable waterproofing and quick installation
Price per sheet: from 392 rubles.
On forums on the Internet there are often discussions of “andulin roofing” or “andulin”. This spelling is not entirely correct: the name comes from French word“Onduline”, accordingly, in Russian “ondulin” also begins with the letter “o”.
The first plant for the production of corrugated sheets opened in the suburbs of Paris in 1944, since then the name trademark hasn't changed.
Ondulin SMART is equipped with a special Smart Lock hydraulic lock made of two strips extruded along the edges of the sheet. Guide grooves regulate the end overlap and form tight joints. Factory marked mounting points make installation easy.
Ondulin “DIY” - resistance to stress and easy transportation
Price per sheet: from 412 rubles.
DIY corrugated sheets fall under the DIY category. The small width simplifies transportation - the material easily fits in the trunk of a car. The higher price per square meter of roofing (compared to Ondulin Smart) is explained by the increased number of overlaps. The finished coating is more durable and can withstand high wind and snow loads. Ondulin DIY is recommended for areas with harsh climates.
Ondulin "Tile" - long-term operation and bright color
Price per sheet: from 467 rubles.
By appearance Ondulin tiles resemble classic analogues made of ceramics and metal. Graduated tinting of individual areas creates a volume effect, and innovative technology dyeing ensures color fastness.
The price of Ondulin does not include the cost of branded nails. They are purchased separately, at the rate of 18 fasteners per sheet. When calculating the number of sheets, it is necessary to take into account the roof slope angle: the smaller it is, the more overlaps will have to be made. The approximate usable area of Ondulin is 1.56 m2 at a slope of more than 15 degrees, 1.52 m2 at 10-15 degrees and 1.29 m2 on a flat roof.
Roofing solutions from Ondulin
In appearance, ondulin roofing resembles slate roof. The materials are united by a wavy profile, color scheme and almost identical size, but that’s where the similarities end. For the production of Ondulin they are used environmentally clean materials: cellulose fibers, bitumen, polymer resin impregnations, mineral dyes and natural pigments. The brand's line includes three types of roofing sheets - SMART, DIY and Tile. They differ in size, price and color range.
Ondulin roof colors
The tint range of DIY and Ondulin tiles is presented in red, brown and green. There is another option for Smart sheets - black (slate).
Green tiles Ondulin
Brown tile Ondulin
Red tile Ondulin
Ondulin's colors are distinguished by restraint and unobtrusiveness. Matte roofing sheets go well with wooden and brick facades, harmoniously complement the cladding made of plastic and metal siding. Most often, Ondulin is matched to the main color of the house, but there are more original ways- play on contrast and combination of several shades. The unified profile of the sheets allows you to combine them in any variations.
Advantages of roofing coating Ondulin
- Long service life. The waterproofness guarantee reaches 15 years, but in reality Ondulin lasts 2-3 times longer.
- Affordable price. In addition to the low cost of the material itself, savings on installation are added. You can handle laying corrugated sheets yourself.
- Light weight. Another saving point is that to transport Ondulin you do not need to hire transport and pay for the services of loaders. Sheets are placed in passenger car and weigh no more than 6.3 kg each.
- Chemical and biological stability. The material is not afraid of exposure to alkalis and acids, and fungus does not appear on it.
- High-quality waterproofing. Smart Lock technology is responsible for the absence of leaks, additional protection provide branded nail heads.
- Silence and comfort. Unlike metal tiles, Ondulin hides the sounds of rain and snowfall. In the attics you can’t hear the sound of rain, the steps of birds on the roof and the sound of falling leaves.
- Ecological cleanliness. When heated, the roof does not emit harmful fumes.
Unfortunately, in Lately Low-quality counterfeits have appeared on the market, and along with them, complaints about deterioration in the performance characteristics of products. When purchasing Onduline, pay attention to the factory markings of the sheets - each of them is marked with the name of the Onduline brand, the code of the country of origin, the batch number and the date of manufacture. Avoid establishments selling “andulin roofing” and contact official dealers.

Dimensions of Ondulin sheet and its overall characteristics
No one goes for building materials at random - this is, at least, unreasonable. Before purchasing, we always calculate how much of something we will need. So, for example, when choosing ondulin for a roof, the dimensions of the sheet should be clarified in advance. After all, having taken an insufficient amount material, you can, while purchasing more, be quite upset when you see that the shade from the new batch is not at all the same, well, but you also don’t want to overpay. Therefore, in this article we propose to understand what sizes Ondulin and its additional elements are, as well as how to calculate the required amount of this material for the roof of a house.
Measuring a sheet of ondulin
French three-millimeter roof covering with the name ondulin (or euroslate) is based on organic cellulose fibers. For strength and color preservation, the material is impregnated with bitumen with special additives.
During the manufacturing process of standard ten-wave sheets, the following deviations are allowed:
- across sheet width: from -5 to +5 millimeters;
- along the length of the sheet: from -3 to +10 millimeters;
- by wave height: from -2 to +2 millimeters.
And now the parameters of the Euroslate sheet themselves:
- Sheet width – 0.95 meters;
- sheet length – 2 meters;
- wave crest height – 3.6 centimeters
- sheet thickness - 0.3 centimeters;
- leaf weight – 6 kilograms.
During installation you will also need fasteners and accessories. In addition to specialty nails, eaves, valleys, gables, gutters and eaves cores, windows, and roof vents will be needed. You should definitely take them all into account.
Dimensions of additional Ondulin elements
Determining the required amount of roofing covering
Typically, these calculations are undertaken by the company that will install the ondulin roof. Usually she sells it. However, if you want to cover the roof with Euro-slate yourself, then to calculate its amount, the size of ondulin and school knowledge in mathematics will be quite enough. You just need to imagine the entire surface of the roof in the form of simple geometric shapes– triangles, rectangles, squares. Having easily calculated the area of each, add them all up - this is the roof area.
And now the most important thing is to avoid making the main mistake of choosing “dirty” sizes instead of “clean” ones. Otherwise, without taking into account the margin required to overlap the ondulin sheets. It is necessary, otherwise the quality of the roof will suffer. Therefore, simply multiplying the length and width, giving a sheet area of 1.92 square meters, is not suitable for determining material consumption. After all, about 0.3 square meters from this sheet will be spent on overlap.
Now more accurate calculations. When the roof is laid, the ondulin sheets overlap not only in the longitudinal, but also in the transverse direction. The overlap in length will be from 10 to 15 centimeters, and in width - one wave (9.6 centimeters). We get the “clean” dimensions:
With these dimensions of the ondulin sheet, its useful area will be smaller - from 1.6 to 1.64 square meters. And one more thing: do not forget that the roof will have to be trimmed along the edge, and 10 percent more material will be needed. Base yourself on these numbers when purchasing roofing.
Dimensions of ondulin sheet and its price
The roofing material ondulin (euro slate) belongs to the category of soft roofing. Sheets of this material are made from organic fibers impregnated with bitumen at high blood pressure and temperature.
The outer side of ondulin is covered dyes and special resin.
Thanks to this, the material acquires attractive appearance and additional strength.
Benefits of ondulin
This roofing material has the following advantages:
- good sound absorption;
- high strength;
- simplicity and ease of installation;
- does not contain asbestos;
- ease of care;
- low price;
- condensation is almost completely absent.
How much does one sheet weigh?
One of the main advantages of ondulin is its low weight. One sheet of ondulin, having 10 waves, weighs 6.5 kg. For comparison, one square meter ceramic tiles is approximately 40 kg. Due to this, the process of laying the material is greatly simplified. Even one worker without a partner can lift the sheets and install them. Ondulin sheets are light in weight and do not create significant pressure on the roof frame. Therefore, it does not need to be strengthened.
Ondulin sheet dimensions
A standard size sheet of ondulin has a length of 200 centimeters and a width of 96 centimeters. The thickness of the roofing material is three millimeters. However, ondulin is not inferior in its rigidity to metal tiles.
photo of ondulin sheets
The wave height of the sheet is 36 millimeters. Also very recently on the market building materials Ondulin SMART appeared, the length of which is five centimeters less.
Ondulin can withstand loads of up to 960 kg/s per 1 sq. m of roofing. Most often in such cases, only the rafter system and roof sheathing are destroyed.
Material strength
Wave ondulin has enough high strength. A standard sheet can withstand pressures of more than 1800 kPa. This is enough to withstand a layer of snow during the winter months, as well as the weight of several workers.
Heat resistance of the material
According to the manufacturers, Euro slate does not lose its shape and characteristics at temperatures up to 110 degrees Celsius. But not all consumers agree with this. Many people claim that the edges of the roofing material melt in extreme heat. This also produces a special smell.
Sound insulation of Euro slate
The ondulin coating absorbs noise quite well, the value of which does not exceed 40 dB. When it rains, the noise will not be heard. It should be noted that the parameters of this material may vary depending on the country of origin.
Price per sheet
The cost of one roofing sheet is 200-400 rubles. Ridge elements cost 230 rubles, valleys - approximately 200 rubles, gable profile - from 230 to 250 rubles, cornice filler - from 30 to 50 rubles. The cost of the Ondufshesh lining carpet is in the range from 800 to 900 rubles.
Calculation of the amount of ondulin on the roof
The main mistake when calculating the amount of ondulin per roof is taking into account real area roofing sheets instead of useful ones. The actual area of the ondulin sheet is 1.9 square meters. m. However, the useful area of the sheet when the roof is tilted from 15 degrees is 1.6 sq.m. This difference arises due to the fact that ondulin is laid with an overlap in width and length.
Calculation of ondulin for a roof of complex shape
If the roof has a complex configuration, the calculation of the material is carried out differently. To do this, you need to divide the roofing surface into sections, calculate their areas separately, and then add up the areas.
The resulting value will be the total roof area. Next, you need to calculate the number of sheets using the above formula. It is better to buy roofing material with a small margin. The number of nails per sheet of ondulin for the roof is 20 pieces, per gable - 5 pieces, per roof ridge - 20 pieces.
Installation features
When choosing the pitch of the sheathing for ondulin, you should focus on the angle of inclination of the roof. If the slope does not exceed 10 degrees, then the ondulin sheets should be attached to a continuous sheathing made of OSB boards or plywood.
The overlap in width is 2 waves, and in length - 30 centimeters. If the roof slope is 10-15 degrees, then the sheathing is made from boards or timber.
The sheathing pitch should be from 40 to 50 centimeters. The overlap in width is made in one wave, and in length - 20 centimeters. If the slope of the roof slopes is more than 15 degrees, then the sheathing pitch should be 60 centimeters. The overlap of roofing sheets is made in one wave in width and 17 centimeters in length.
Installation of sheets
First of all, install cornice strip. Next, the first row of ondulin sheets is laid along the eaves overhang. The installation of the first sheet is carried out flush with the gable overhang. Also, the sheet must extend beyond the roof eaves by at least 5 cm.
Each sheet of ondulin should be secured with 20 nails. First of all, fix the corners of the sheet. Next, fix the lower edge of the ondulin in each wave. The top and middle of the roofing sheet are fastened in a checkerboard pattern through one wave.
After laying the first row with the required overlap, proceed to install the second strip of material in the same way. It should be noted that even rows (second, fourth, sixth, etc.) must be started from half a sheet.
Installation of the valley and ridge element
At the next stage, the roof ridge is installed. It is mounted at the junction of two roof slopes. The ridge element is fastened using nails (in each wave of Euro slate).
Valleys are an element of roofs of complex shape. They are installed at the junction of two roof slopes in inner corner. Before installing the valley, it is necessary to lay a waterproofing carpet. Laying the valley begins from bottom to top. In this case, it is necessary to maintain an overlap of 10-15 centimeters between the elements. The amount of overlap should be selected depending on the slope of the roof slopes.
To fix the valleys, I use special clamps nailed to the roof sheathing. It is not recommended to nail valleys through and through.
Ondulin sheets are laid overlapping on the grooves and cut off. This is done in such a way that the distance from the center of the valley to the edges is 5 cm on both sides. Filler is placed in advance under the ondulin sheets. Euro slate should be fixed in each wave.
When performing installation work, certain rules must be observed:
- laying of the material should be carried out at temperatures from -5 to +30 degrees Celsius;
- it is necessary to control the horizontal installation of roofing sheets;
- to cut ondulin you should use a hacksaw or an electric jigsaw;
- Ondulin should not be stretched, as its structure may be damaged.
Ondulin: sheet sizes and other characteristics
The roofing material ondulin (Euro slate) is “gaining momentum” in Russia and is increasingly being used on roofs of any type with a slope angle of 5 degrees or more.
It is easy to install, transport and operate, and has unique technical characteristics that you need to become familiar with before installation.
Sheet sizes
The standard dimensions of an ondulin sheet (L*W) are 2 meters by 96 centimeters.
The thickness of the material is 3 millimeters, but its rigidity is not inferior to, for example, metal tiles.
The height of the wave is 3 centimeters 6 millimeters. Not long ago, SMART ondulin appeared on sale.
Its length is 5 centimeters shorter.
The weight of an ondulin sheet with ten waves is 6.5 kilograms, its installation is greatly simplified.
One person can lift Euro-slate onto the roof and work with it there, without the help of a partner.
A roof covered with ondulin will not exert strong pressure on rafter system, so there is no need to strengthen it.
The strength of a standard sheet of roofing material is more than 1800 kilopascals.
This is enough to withstand significant snow loads and the weight of several people.
Euroslate can withstand loads of up to 960 kg/s per 1 square meter of coverage.
Often, only the sheathing and rafter system are destroyed.
Thermal resistance
However, not all consumers agree with them. You can often hear complaints that the edges of the material begin to melt in extreme heat, and a specific smell arises.
Noise insulation
Euroslate absorbs noise well, up to forty decibels.
The sound of rain on the roof will not be heard.
Material characteristics may vary depending on the country in which it is produced.
Check them out in the table.
The cost of roofing material ranges from 200 to 400 rubles.
Valleys cost approximately 200 rubles, ridge elements - 230 rubles, cornice filler - 30-50 rubles, gable profile - 230-250 rubles, underlay carpet onduflesh - 800-900 rubles.
Calculation of ondulin on the roof
The main mistake that is made when calculating the material for a roof is taking into account the actual area of the sheets, and not the useful one.
The actual area covered by one sheet is 1.9 meters (2m x 0.95m).
But the useful value for a slope slope of 15 degrees will be 1.6 meters. This scatter occurs because the ondulin is mounted with an overlap in length and width.
To determine the number of sheets, use the formula: K = roof S/S useful sheet(coefficient).
The formula makes sense if the calculation is made for a gable roof, on which there are no complex geometric transitions and junctions.
The useful area of the sheet varies depending on the slope of the slopes.
If the slope is in the range from 5 to 10 degrees, then the coefficient is 1.29 (m2).
With a slope of 10 to 15 degrees, it will already be equal to 1.54.
Calculation example
Let's imagine that the total area of the gable roof of your house is 100 square meters.
The useful area that one sheet will cover with a slope slope of 15 degrees is 1.6 meters.
Now let's divide 100 by 1.6. We get the number 62.5. Round it up to a whole number. As a result, you need to purchase 63 sheets to cover the entire roof.
If the slopes were located at an angle of 10 to 15 degrees, then the value of 100 would have to be divided by a coefficient of 1.54, etc.
Roofs of complex shapes
When the roof has many slopes connecting to each other, other architectural excesses, the calculation must be carried out differently.
One of the options is this: the entire surface of the roof must be divided into equal sections, and then sum up their area, obtaining the total.
Installation features
The pitch of the sheathing for Euro slate depends on the slope of the roof.
So, with a slope slope of up to 10 degrees, a continuous sheathing of plywood or OSB board must be made under the roofing material.
The sheets are laid with an overlap in length - 0.3 meters, in width - 2 waves.
When the roof slope is from 10 to 15 degrees, timber or boards are used for sheathing, which are mounted at intervals of 40-50 centimeters.
The overlap in length is 0.2 meters, in width – 1 wave.
When the slope of the roof slopes is over 15 degrees, the sheathing is installed in increments of 60 centimeters with an overlap of 17 centimeters in length and 1 wave in width.
Laying order of sheets
First, the cornice strip is installed.
Then the first row of sheets is installed along the eaves overhang.
Laying begins on the side of the roof opposite to the prevailing winds.
If the wind blows more often from the left, then installation is carried out from the right.
The first sheet is laid flush with the gable overhang, and its “exit” beyond the cornice must be at least 5 centimeters.
To fasten one sheet you need 20 nails.
First, it is fixed at the corners, then its lower edge is attached to each wave.
The center and top of the sheet are “sewn” through the wave in a checkerboard pattern.
The photo clearly shows the process.
After all the sheets of the first row are laid with the necessary overlap, lay the second strip in the same way.
The only condition is that the first sheet must be half.
The process is repeated in the fourth, sixth row and so on.
Installation of ridge and valleys
The next stage is the installation of the ridge element.
The ridge is placed at the junction of two slopes and fixed with nails into each wave of ondulin.
Valleys (valleys) – element complex roofs. They are mounted at the junction of two slopes in the inner corner.
A waterproofing carpet is first placed under them. Laying begins from the bottom up.
The overlap of the elements with each other is 10-15 centimeters, depending on the slope of the slopes.
The grooves are fixed using special clamps that are nailed to the sheathing.
Sheets of ondulin are laid overlapping the grooves and cut off so that the distance from the edges to the center of the valley is 5 centimeters on both sides.
Filler is pre-laid under the sheets. Ondulin is nailed into every wave.
A few tips to make your work easier
When installing ondulin, observe the following rules:
- Work is carried out at temperatures from -5 ° to +30 °;
- Always check that the sheets are stacked horizontally;
- Cut the sheets with a knife, hacksaw or electric jigsaw;
- Do not stretch ondulin so as not to damage the structure of the material.

It is these parameters that attract the attention of numerous consumers.
Ondulin: roof calculation and dimensions, price per sheet
Roofing material ondulin (Euro slate): characteristics, sheet size and prices - installation features and order of laying sheets.
Bitumen sheets"Onduline" have high performance characteristics and are able to withstand heavy loads and climatic conditions. The price of ondulin is distinguished by its affordability, and the material can last up to 50 years. Manufacturers offer several types of this material. They have certain differences and the same performance characteristics. This article will look at the dimensions of the ondulin sheet for the roof, average prices for the material and additional elements.
Types of “Onduline” coating
Today you can buy several types of ondulin. The most common type is “Ondulin Smart”. It is the most common and is considered a practical roofing option. The material is lightweight and easy to install.
The main advantages of such a roof are resistance to strong temperature fluctuations and noiselessness during precipitation; the sheets have convenient sizes for installation and low cost. The warranty for this roofing is 15 years. Available in several color ranges. The cost of the material is about 250 rubles. per m².
The second option is tiles made of the same material. The peculiarity of this roofing material is that the coating has classic look tiles At the same time, all the characteristics and advantages are the same as the previous version. The shingles also come with a 25-year warranty and come in several colors. Such material can be purchased at a price of approximately 480 rubles. per sheet.
Ondulin Smart has some differences from the classic ones - it is a lock that helps to install them faster and easier. There are special strips along the edges that protect against water penetration; the size of the overlap has been reduced, which allows you to save on material when covering large areas.
The locks have strips that can be used as guides, helping to make the roof as level as possible. All sheets have markings for nails. Such sheets have standard sizes 1.95x0.96 m. The thickness is similar to ordinary sheets - 3 mm, and the wave width is 9.5 cm. However, they weigh a little more - 6.3 kg.
Installation of sheets
The price per sheet of andulin roofing makes this material one of the most popular. It also has the advantage of fast and extremely simple installation thanks to special elements. The technology is reminiscent of laying classic flooring, where sheets are laid on lathing or old carpet. The material can be used for roofs with different slopes, and the greater the angle, the smaller the pitch of the sheathing.
While working, you must adhere to some rules:
sheathing can be done from boards, OSB or plywood, a solid base is made if the angle of inclination is less than 10 degrees;
styling we need to start downwind, the overlap is done on one wave, thanks to the locks the rows are even;
Ondulin is a modern alternative to slate. It is based on cellulose impregnated with bitumen, minerals and pigments. The material is safe and environmentally friendly. And thanks to the size of the sheet, installation does not take much time. The sheets overlap comfortably and are adjusted to the required dimensions.
Benefits of ondulin
One of the main advantages of such coverage is its cost. You can buy ondulin for the roof, the price per sheet of which is 450-550 rubles, in different colors, which will complement the design of the house. Another significant advantage is the ease of installation of the roof due to the light weight of the sheets. This is an additional saving on delivery and the ability to carry out all installation work faster compared to, for example, slate. The material simply adapts to all sizes as a result of the fact that it is very easy to cut.
The light weight of the material guarantees minimal load on the roofing system, which allows you to save on rafters. This type roofing material can be laid on top of the old one, this way you can save on dismantling. The material is environmentally friendly and safe for people and environment. It is resistant to the development of mold and mildew thanks to special fillers. The material has high noise insulation properties.

Characteristics of ondulin
The cost of ondulin is determined by its certain features and performance characteristics. The roofing itself is similar to regular slate, but includes other components that were mentioned above. This material can be used for arranging roofs of buildings for various purposes, both houses and social facilities and other buildings. It is absorbed due to the fact that ondulin does not contain asbestos, and therefore it is safe and environmentally friendly.
Sheets are available in the market in four colors - green, red, brown, and slate. The width of each sheet is 0.96 m and the length is 1.95 m. It should be noted that each sheet of ondulin is 4 kg lighter than slate, its weight is slightly more than 6 kg, and its thickness is only 3 mm. But the material itself is very durable, so it can withstand quite heavy loads.
The material is widely used in the construction of various facilities, industrial, commercial, residential or light structures. It is lightweight and can be mounted on flat old roof coverings. The load of the new coating is on average 3 kg per square meter.
Ondulin sheets produced under a French license are sold on the domestic market. The standard sheet is 95 cm wide, 2 m long, only 3 mm thick, and the wave height is 36 mm. There may be a slight error of +/- 2mm wave height, +/- 5mm width and +10/-3mm length.
For the production of sheets, compressed cellulose fiber is used, which as a result resembles ordinary slate. It is impregnated with bitumen, with resins and mineral pigments on top. Thanks to the materials used, the sheet can bend transversely and longitudinally, and is lightweight with a total area of 1.9 square meters.
The sheets have 10 waves, the width of which is 95 mm. During installation, an overlap is made in one wave for horizontal laying, and for vertical laying - 10-15 cm when the slope is inclined more than 15 degrees. When laying sheets, the useful area of each in this case is approximately 1.6 square meters. With a slight slope, the vertical overlap is 20 cm, and the sides are two waves. Taking these facts into account, it is necessary to carry out careful calculations with a specialist so that you do not need to purchase additional material.
