How to work with a gas burner for roofing. Roof burner: review, types, characteristics and reviews

For carrying out repairs and other roofing works, which involve melting mastics and laying roofing materials, you will need a special gas burner. The device is primarily used to perform the following tasks:

Heating and drying of roofing materials;

Metal cutting and soldering;

Layer firing old paint.

Approximate structure of a gas burner

The gas burner has enough simple design. It is a glass made of metal and equipped with a nozzle and a handle, which is attached to the body. Heat-resistant plastic or wood can be used to make the handle. Gas enters the housing passing through the gas pipeline. In most cases, propane under pressure is used to operate the burner.

The burner glass should have a shape that protects the flame from being blown out by the wind.

There is a valve on the burner body that allows you to adjust the flame length and intensity of the supplied gas. It’s good if the burner has a reducer, which allows you to use gas economically.

Roof burner components

During the assembly process of the device, mechanical processing is practically not used. The burner is assembled from ready-made spare parts. To make it we will need:

A steel valve that can be taken from a storage cylinder liquefied gas.
A plug used for transporting gas cylinders.
A nozzle from a blowtorch with a nozzle diameter of 0.8 mm.
A piece of pipe one meter long with an internal diameter of 10 mm. and steel thickness 2 mm.
Wooden handle.

You can use the handle from a burnt-out soldering iron as a handle.

Step-by-step burner manufacturing process

The process of manufacturing a gas burner begins with the fact that we insert the supply tube, for which we will use a steel pipe, into the handle and secure it with glue. The divider and body must be machined from a brass rod, the diameter of which should be 20 mm. In the finished body, two radial holes are drilled (each diameter is 5 mm) and four holes are drilled in the divider rod (each diameter is 1 mm).

When assembling, it is necessary to press the divider into the body with a slight tension. At the same time, the flange must be installed inside the housing with a gap, that is, the internal diameter of the manufactured housing must be 0.6 mm larger. diameter machined The resulting gap is responsible for inhibiting the gas flow, which is supplied to the drilled holes in the igniter.

Such nozzles are found in purchased models

To make a thin hole in our nozzle, you need to take a drill with a diameter of 2 mm. and use it to make a blind hole, which is 1.5 mm. doesn't reach the exit. Drill with a diameter of 0.4 mm. used for jumper. The resulting hole must be completely caulked with gentle hammer blows. Then you need to sharpen the end. To do this, take sanding paper and sharpen it until the desired cross-section of the outlet hole is found, that is, until the nozzle can be placed on the tip of the threaded burner tube.

A supply hose made of fabric-rubber material must be attached to the end of the gas supply tube. Secure the hose to the tube with a clamp. We exhibit operating pressure, after which we supply gas. Wait until all the air is forced out of the hose, and only then insert the nozzle into the flame of the gas burner.

Attention! The nozzle is introduced into the flame without a housing or a divider.

Next you need to sand the end. The length of the burner flame should ultimately be 5 cm. We put the body together with the divider on external thread injectors. Make sure that the burner produces an even flame with no signs of soot.

In order to achieve desired effect, slowly turn the body on the injector thread.

If you have a loose threaded connection, seal it with FUM tape.

Video. How does a roofing gas burner work?

Hello! My name is Viktor Kaploukhoy. I am an engineer by training, graduated Technical University. Hobbies: IT, engineering and technology.

In just two decades, construction technologies have been updated, new building materials and tools have appeared. For example, the old faithful roofing felt has given way to new fused roofing materials, which are better in all respects. No one will argue with this anymore. And accordingly, the bucket with hot bitumen and a brush for coating has gone into oblivion, instead of which builders today use a gas burner for roofing work.

What is a gas burner

This hand tool connected to a gas cylinder. It includes:

An injector with a nozzle installed inside through hole small diameter. Through it, gas in the form of a flame is supplied to the place of surfacing or drying.
Cup. This is a device within which flammable gas is mixed with air (oxygen). The glass has many holes through which air is sucked into the flame zone. In addition, this device protects the fire flame from the effects of wind.
A valve that opens the gas supply and regulates its pressure, and accordingly the length of the torch.
The main pipe that separates the torch from the handle that the welder holds.
Handle made of plastic or wood.

Of course, to operate a gas burner, you need a hose connected to the cylinder and a reducer that reduces the gas pressure in the line. The gas pressure at the burner outlet is 0.1-0.15 MPa. A propane gas burner for roofing weighs a little, in the range of 1.0-1.5 kg. So it is convenient and easy to work with it.

How to make a burner with your own hands

In principle, the design of a propane gas burner is simple. The main thing is to assemble the nozzle and glass. The remaining elements and parts are ready-made units and parts that are sold in any hardware store. Therefore, it will not be difficult to make it yourself.

So, what is required to assemble a burner with your own hands?

Gas burner assembly

First of all you need at one end copper tube cut the internal thread using a tap of the appropriate diameter. Copper is not a very hard metal, so it will not be difficult to carry out this operation with your own hands. It will also be easy to screw in the jet.

With a glass everything is more complicated. To do this, you will have to cut one side of the pipe into several longitudinal petals (6-8 pieces), and then bend them towards the center. You will get a cone, but there is no need to bring the petals to the end; you need to leave room for the main tube, onto which the glass is placed. After which the petals are pressed against the tube, where they are sealed. There are slots between the petals that will serve as air supply inside the nozzle. The length of the petals is approximately one third of the entire length of the glass.

Important! The jet should be located at a distance equal to the length of the petals. That is, a flame of propane and oxygen should form at the level of the slots.

The gas burner for roofing work, or rather, its front part in the form of a nozzle is ready. All that remains is to assemble the back part. To do this, you will need two M25 bends made from a pipe with a diameter of 25 mm with threaded threads. In a one-way bend, in a place where the thread is not cut, a cone is formed into which the rear part of the main tube is inserted. This can be done by heating the squeegee with an oxygen torch and tapping it on all sides.

A gas control valve is screwed into it. The second connection, it is double-sided, is screwed into the valve on the other side. Be sure to wrap it on a sealing material. For example, on fum tape. An adapter from threaded connection to the hose. There is no point in making it yourself, because it is sold in any hardware store and is very cheap.

Now all that remains is to make the handle and install it on the prepared device. Handle options – great amount. The main thing here is to hold the entire homemade device comfortably. For example, it can be cut from wooden board 5 mm thick, you can buy an ax handle and adjust it to the size and shape. It is better to attach the handle to the brackets, because this is the strongest section in the entire structure. Optimally, this is a rear drive, because the control valve should be located slightly in front for ease of use.

There are different ways to attach a piece of wood to a metal tube.

Make a recess along the entire width to fit the diameter of the pipe of the squeegee, place the squeegee in it and secure it with two clamps made of metal tape.
Install the squeegee on the side of the handle and also secure with clamps.

So, you have made a gas burner for roofing work yourself, you can connect it to a gas cylinder and carry out testing. To do this, the hose is connected to the cylinder through a reducer, where it is secured with a clamp. Its second end is threaded into the adapter, where it is also secured with a clamp.

The cylinder opens, the supply of propane through the gas reducer opens. And the last thing to open is the control valve on the injector. Gas should flow through the nozzle with a characteristic sound. You must wait until the air inside the device is completely released. After which the gas flow is ignited. The valve near the handle regulates the length and power of the torch.

Attention! A homemade gas burner for roofing work is a high-risk device. Therefore, all operations performed must be approached with special care. This is especially true for the connections of all elements with each other. Complete tightness must be maintained.

Fire safety measures

Regardless of whether a factory gas burner is used or a homemade one, fire safety requirements must be strictly observed.

Keep a fire extinguisher on the roof when performing roofing work.
All work is carried out only during daylight hours.
On the roof when laying soft roof Using a gas torch, you can only carry one propane cylinder.
It must be avoided from heating up.
The roofing material itself must not be overheated or ignited.

Like these ones easy conditions, which guarantee the safety of construction operations involving roofing with fused materials. They are simple and easy to do, so there shouldn't be any problems.

Roof microburner– this is a movable structure with comfortable handles for carrying. The Sympathy contains a small mass, up to 1.5 kilograms, and is equipped with a handle made of logs or plastic, up to 1 m long, that is comfortable for carrying out activities.

In the gas property, the only thing used is hydrocarbon. Someone acts in the shell using a gas hose. Its supply and length of fire are regulated with the support of a special valve in the burner. In order to save exhaust gas, roofing games are equipped with a gearbox, which controls fuel consumption.

Absolutely all gas burner systems take into account the concept of atmospheric suction. This is an inevitable role, but it is also necessary to accept auxiliary ones, which provide the service in the most convenient way.

In the main priority is the possibility of coordinating workers' regimes. For example, if there is a stop in the service, the order of hope is introduced and fuel is saved. Each gas microburner lights up with ordinary matches or a lighter.

Less known, but also used for roofing work, are games that operate in diesel fuel.

What kind of equipment is this?

The structure of the burner includes an owner with gas supply regulators, from what it turns out Railway with mixer at the end. The microburner is connected with a rubber sleeve to the hydrocarbon-slide gas cylinder using a pressure regulator.

Basically, tamed gas games are used to heat the surface and fuse various substances. Gas games come in two types: forced and non-forced atmosphere.

These types of burners have the following characteristic industrial properties:

Atmosphere supply in a gas burner with forced supply performed in the following way, air is supplied with the support of a propeller or compressor. The advantage of this type of game is the likelihood of a clear torch option. The downside is the difficulty of installing the device.
In burners that do not have a forced supply of atmosphere, air is supplied freely through a hole in the diffuser due to the number of gas supplies. The simple structure makes it possible to do it yourself. The disadvantages include the inadmissibility of a clear torch option.
The gas microburner is started by igniting a gas stream, which is obtained from the diffuser; in some modifications, automatic ignition is taken into account.

Design and principle of operation of the burner

The design of the gas game consists of the following elements:

A metal cup with convex holes along the sides.
A nozzle for the purpose of spraying gas.
Plastic or wooden owner.
Rubber sleeve with the purpose of gas cart to the body of the game.
Valve for regulating the supplied gas and the length of the fire.

Due to the modification, the game has the following differences:

The fuel supply is injection and non-injector.
Power and gas consumption.
The amount of fire supplied. Accept single-flame and multi-flame.
The method of using the device is easy and electromechanized.

The length of the game due to its installation is from 0.8 to 1 meter and the weight is approximately 1.5 kg. In addition, due to the modification, gas games can be equipped with different fuel saving modes.

Roof burner models

For work related to laying the roof, a specified type of device with the following modifications is used:

GG-2 propane micro-burner for the purpose of preparing and performing waterproofing work. Excellent for small-scale roofing work. Recommended for use by young professionals. Mostly low price.
GG-2U The similarity of the previous modification is distinguished by the curly gas route. It is mainly used in inaccessible areas near the roof.
GG-2S It seems to be a high-quality burner, and in addition it operates in propane. Contains 2 valves for the purpose of clearly regulating the order of operation and the likelihood of operation in very windy weather.
GS1-1.7 contains small mass, and the volume appears to be multi-purpose. It is used for the purpose of drying and fusing substances into the roof. Makes it possible to heat the plane up to four hundred degrees.
GK-1 The air-propane microburner is armed with a depressing cup and a gas supply lever. It is used for the purpose of removing color by burning in wood surfaces and waterproofing roofs.
GS1-1.0 contains a simple mass and small volumes, which makes it possible to use it for waterproofing roofs with a huge slope.
GGS1-0.5 Mainly used for the purpose of small repairs to the roof and for economical use of gas in a project.
GGS4-1.0 contains 4 cups of fire supply. It seems economical and allows 1 person to process a large amount of shelter in a short period of time.
GV-3 used primarily for the purpose of heating metals for welding or soldering.
GV-111R used for the purpose of fusing narrow-roll bituminous substances into the roof. In addition, it is used for the purpose of firing the previous color in different surfaces.
GV-50, GV-900 comfortable and easy to use, distinguished by the length of the torch.
GV-500 I use it for the purpose of fusing bituminous substances. Makes it possible to warm up the heated surface up to THREE HUNDRED degrees.
GSV-850 contains an injection type of fuel supply. The microburner is equipped with a valve for a clear gas supply option and a lever for adjusting the length of the torch.

Interest must be directed to similar characteristics, as well as:

Fuel requirement.
Flame torch size.
Heat performance.
Weight and length.

Application of gas burners

For the purpose of repair work and the adaptation of roofing with bituminous substances, a gas burner is preferably used. Due to 8 hours of labor time, approximately 600 square meters of welding material can be placed next to a high-quality burner.

Carrying out work in accordance with the adaptation and repair work of the shelter different types with the use of gas, the installation must be laid in accordance with absolutely all fire protection laws.

For work on laying different areas of the roof using gas, accept established limits such as:

You can only lay no more than 500 square meters at a time.
When laying more than 500 m, the presence of fire hoses with water is necessary.
Has access to fire hydrants and is required to appear at four edges of the mulched roof.
Water supply using a fire hose must be supplied to each point of the laid plane.

Stages of work when laying material using a roofing torch

The procedure for laying bituminous or so-called soft surfaced substances using a gas game consists of the following steps:

Cleaning the roof surface from debris.
Unwinding the rolls in the plane of the roof with an overlap of at least 10 cm for marking purposes. Subsequently, the rolls must be wound and numbered.
Priming the plane with prime in order to remove microcracks, chips and dust binding.
Having marked the plane and primed it, the rolls are unwound over time and heated with a gas burner in order to fuse it into a plane.
During the final period of laying movement, it is necessary to heat the seams of the deposited substance with a torch.

After fusing the substances, in order to prevent wrinkles, the covered plane must be rolled out with a roller.

How to make a gas burner with your own hands?

A gas burner can be made personally in domestic circumstances; for this purpose, the following components will be needed:

Rectifier with pressure reducer to regulate gas supply. It can be taken from an oxygen cylinder.
A stopper that is used for transporting gas cylinders.
Liquid fuel nozzle with a nozzle diameter of 0.8 millimeters. It can be taken from a gasoline blowtorch.
A piece of iron route, a tube version, with a length of only one unit with a diameter of 10 millimeters and a wall width of 2 millimeters.
Handle made of slightly heat-permeable substance. Mostly from a log.
Shell and gas divider game (cup). They can be turned from a brass rod with a diameter of 20 millimeters.

The further installation procedure for the gas game consists of the following steps:

The road is inserted into the made handle and secured with glue.
In the turned body it is necessary to drill 2 radial holes with a diameter of 5 millimeters. In addition, in the housing it is necessary to drill 4 holes with a diameter of 1 millimeter in the divider rod.
The next step in the game production is simply sketching the cutting rod into the shell. The completed shell must be fixed into the railway.
In the routes with the inserted housing, it is necessary to cut the thread with a tap and screw in the nozzle.
At a different route end, a gas-air hose is connected and secured with a clamp.

After installing the gas game, you need to unscrew a certain oxygen rectifier and wait until the blue fuel squeezes out the air space in the sleeve. Then use matches to burn the flow of gas from the body (glass).

Safety rules when working with gas burners for roofing

When operating a gas burner, strict compliance with the security laws is necessary:

Before starting the activity with the device, it is necessary to carry out an inspection of the game into the object of automatic defects and loss. ant. gas income. Micro burner for roofing work
The arson game cannot be played by standing in front of the glass nozzle.
Work must be carried out using canvas gloves, overalls and shoes.
When working with a gas burner, you must be careful not to overheat the raw material being welded. Thus (as well as overheating can cause destruction of the substance.
On workplace Where the microburner is used must not be exposed to third-party objects, especially flammable ones.
When working with a gas burner, fire extinguishing resources must be available near the laying area.
The repairman operating with the device is in no way obliged to move with the burnt burner anywhere other than the mulched surface.

The principles of safety during operations with a gas burner must always be observed and indisputably oh, thus it is also a guarantee of the unity of the functioning Person and the people around him.

A gas microburner seems to be a necessary assistant for laying the roof with gentle substances. Such a device, as well as a gas microburner, is widely used in construction and correctional work.

As a rule, gas flames are used for the purpose of fusing roofing materials, removing color from various surfaces, welding and soldering various metals. Game of taking various types systems for the purpose of different types of work.

It should be immediately noted that it is much easier and more harmless to purchase a finished burner than to make it yourself. However, if one accepts the belief in own strength and passion is always accomplished with one’s own hands, in which case it is permissible to try.

Gas micro burner- this is a difficult apparatus and for this purpose, in order to produce it, some skills will be needed, and the detailed implementation of a large number of laws. However, it is always better to preserve the activity element for the purpose of specialists. This primarily concerns the organization of supply and containers in order to preserve gas.

To produce a torch, a metal base and a gas divider are used. Attach them to the handle from a heat-resistant log.

The hose for supplying gas is drawn from a gas welding organization or personally ground from brass.

Despite this, in this case, what appearance The roofing micro-burner, selected with its own handles, differs quite significantly from shop analogues; sympathy will cope with its own main functions.

But next to the service, it is necessary to especially carefully concentrate interest in the smallest gas leaks or other problems. And even on a number of minor issues, the service must be interrupted immediately. Roofing information works in low fuel conditions.

They are especially important for operating near extreme temperatures; in this case they are equipped with integrated fuel heating. They are fully automated and ready to work with gasoline of different properties.

Diesel roofing games are equipped with a high-pressure blower concept, which guarantees stable and reliable ignition and reduces the formation of soot.

Low-fuel burners stand out from their gas counterparts. In a diesel engine, the fuel enters the chamber under great pressure, which leads to water splashing. And the previously sprayed fine particles are ignited at the exit from the nozzle, forming a fire.

In conjunction with this, the microburner is connected to a compressor and a container with gasoline next to the support of oil-gasoline-resistant hoses.

In a home workshop or garage, there is often a need to use a high-temperature burner. It has the widest range of applications – from soldering to roof repairs. Not to mention the need to warm up metal part for processing.

When doing metalworking work on metal, a gas torch can be used to heat the workpiece for the purpose of subsequent hardening. If you are engaged in electric welding, when working with some metals it is necessary to warm up the area of the future weld.

Tool stores sell a variety of tools for safe work with fire. A propane burner can be of any size and any configuration. The size of a ballpoint pen for jewelry soldering:

Or a multi-nozzle ramp for heating bitumen on the roof:

The advantage of industrial options is the safety certificate. However, there is nothing in the design that cannot be replicated at home. Since any product in the store costs a lot of money, we will tell you how to make a burner with your own hands.

Important! Homemade devices for working with fire carry a potential danger. Therefore, a propane torch manufactured without technical expertise is operated at your own peril and risk.

How to make a burner yourself

Let's take a closer look at the nuances that you should pay attention to when making a burner.

First of all, it is necessary to use refractory metals. A properly configured burner can produce up to 1000 ° C, so the nozzle must match the flame temperature;
It is important to choose a reliable working crane. If something goes wrong, the gas supply is first cut off and the danger is eliminated. If the tap leaks, you will not be able to quickly extinguish the flame;
The connection point to the gas source (a bottle with a valve or a 5 liter propane bottle with a reducer) must be reliable. It is when operating low-quality shut-off valves that most accidents occur.

Let's consider standard diagram and the operating principle of the injection burner:

Gas is supplied under pressure through the hose (1). Typically propane. The pressure is formed due to the evaporation of liquefied gas in the cylinder, and it is sufficient to organize a stable and directed flame. A reducer is not required, the amount of gas is regulated by the operating valve (2).

The shut-off valve is located on the cylinder valve. Its function is only to open/close the fuel supply; other adjustments are made using a working tap.

The gas supply tube (3) leads the jet into the nozzle and ends with a nipple (6), which sets the direction of the flame. The nipple with the tube, in turn, is located in the so-called insert (5). It organizes the mixing of gas with atmospheric air.

The insert with a tube and nipple is fixed in the nozzle with a screw. As a rule, the burner is dismountable for cleaning and maintenance of the nipple.

The formed air-gas mixture is directed to the nozzle of the nozzle (8), where the mixture is additionally saturated with oxygen from the air. For combustion stability, there are ventilation holes (7).

The burner is made by hand according to the drawing.

Dimensions are designed to work with cylinders up to 5 liters.

We will tell you about the structure of the liner separately; the dimensions are shown in the drawing:

The outer diameter of the liner tube (1) should be half a millimeter smaller than the inner diameter of the nozzle. A washer (2) with holes for air supply is welded inside. The sleeve (3) is designed to fix the tube with the nipple.

The peculiarity of the design is that by moving the tab inside the nozzle, you can regulate the air leak through the ventilation holes. This allows you to regulate the flame temperature over a wide range.

The nozzle can be made from a steel pipe, but it would be better to turn it from a steel blank on a lathe. The shape of the nozzle should be somewhat narrowed at the outlet, then the flame will be forced and the temperature in the combustion zone will be higher. Alloy steel grade 45 is used.

There are two ways to make an insert: You can assemble it from two tubes and a steel washer with holes. The structure is soldered with refractory solder, with abundant fluxing. Or you can grind it entirely from a steel blank. The second option is preferable.

The supply tube is copper or brass. On the side of the hose connection, a flange is made (concentric grooves can be made for better fixation). A suitable nipple is screwed into the working end. You can take it from a primus stove, or a gas burner from a household stove.

Important! When using a nipple from kitchen stove Remember that the kit comes with different nozzles. For natural or liquefied gas.

The second option will suit us. When the burner is ready with your own hands, it is necessary to carry out initial debugging.

The burner is set to use the gas that will subsequently be used. The insert is lightly secured with a screw so that the ventilation holes are blocked by half.

By slightly opening the operating valve and moving the insert, we achieve an even, powerful flame. Then we finally fix it in the nozzle.

If you did everything correctly, the temperature at the outlet of the nozzle will reach 1100° C.

Let's move from theory to practice. How to make a gas burner using available materials:

The nozzle is made from a classic car pump design. Such items often lie idle in the garage.
The steel used is excellent and the size is suitable for a gas burner.

We cut a “rose” in the back part, bringing the ends to the center. A feed tube will be inserted into this bundle.

The part came from a construction foam gun.
This is a device for reusable use, so the steel is strong and coated with refractory chromium.

The thickness of the tube is almost 1 millimeter, which is quite enough for rigidity.

At the end of the gun tube there is a nozzle with a ball valve to form foam. The ball is knocked out with a thin awl or gypsy needle. The resulting hole is sufficient to supply gas to the nozzle. The tube with the nozzle is connected using semi-automatic welding.

To connect the structure to the working faucet, conventional plumbing fittings with threads were used. It's simple water pipe, no special steel is needed here. The part of the burner where the tap is located does not heat up to critical temperatures. Ball gas tap had to buy;
The holder is literally made from scrap metal. Handle from a motorcycle footrest. By lightly processing it with a grinder, we get the optimal shape. The clamp for attaching to the burner pipe is from the handlebars of the same motorcycle.

Finally the holder fits on a motorcycle handle. The thermal insulation is good, and the burner fits snugly in the hand.

It took one weekend to make and 100-120 rubles to buy a tap and a fitting for connecting to a hose.

As a bonus, look at the drawing of the tested miniature device:

A gas burner for soldering is made from a needle from a dropper. Connects to a lighter refill bottle.

Conclusion! A homemade gas burner is a reality. Just be careful when operating!

The best option for thermal and waterproofing of a soft roof are materials fused with a gas burner for the roof. This is a rather complex, labor-intensive procedure that is carried out at altitude. Therefore, only high-quality equipment is selected, since the operational period of the roof covering will depend on the final result.

Design features of the roof burner

Burner designed to operate on roofing structure, represents mobile device, equipped with special handles for moving it. The weight of the unit is about 1.5 kg. The burner has a wooden or plastic handle for operation; its length can reach one meter. Such equipment is specially designed for heating the welded roof covering.

Basic operations that can be performed using a roofing torch:

firing of old paintwork;
cutting, soldering of metal products;
drying surfaces;
other work that requires heating surfaces to high temperatures during their execution.

Equipment design elements:

glass made of heat-resistant metal;
ignition nozzles are equipped with special protection from strong winds;
gas mixture supply hose.

Most often, propane gas is used for such equipment, which is supplied to the housing through a special hose. The gas supply and flame length are adjusted using a valve equipped on the tool, and a reducer is additionally used to adjust the flow of the gas mixture.

All designs of this equipment have an air suction system. This feature is required for the tool. To increase the comfort of working with the tool, a special operating mode regulator is additionally provided, which provides the opportunity to save fuel when the standby mode is turned on. To ignite the flame of the instrument, you must have a lighter and matches on hand.

It is important to know! There is also a diesel torch for roof work, but it is not very popular.

How to properly operate a gas burner for a roof

The procedure for working with a roofing burner using propane gas is divided into separate stages. The main roofing covering for which such equipment is used is roofing felt.

Work order

Before starting work, the base for roofing felt is prepared: cleaning construction waste, other contaminants, leveling the surface (if necessary, screed from a concrete mixture is carried out).
Roofing felt is rolled out on the prepared base, with individual sheets of material overlapped on top of each other.
Then roll the roofing felt rolls back and fix them at the base. roof slope gas burner for roofing. After this, while simultaneously heating the roofing material and the base of the roof, slowly roll out roll covering, carefully press it to the base. Adjacent rolls are soldered together.
The laid layer of material must be periodically rolled with a roller so that no air bubbles remain under the coating. The seams are also rolled after soldering.

Operating rules

It is prohibited to carry out installation work using a gas burner if T os is less than “minus” 15°.
Using this equipment, you can cover a roof with an area of about 500 m2.
The device must be equipped with reliable protection from strong winds and have a stable combustion flame.

Safety precautions

Before carrying out roofing work gas hoses, the gas cylinder is checked for suitability for use.
Work is carried out only in overalls, soft shoes and with safety equipment (minimum cables, seat belts).
The gas cylinder is installed near the workplace; all equipment connections must be sealed.
The flame at the moment of ignition of the burner, during operation, is prohibited from being directed towards people, a gas cylinder, or hoses.
Don't overheat too much soft covering roof to prevent it from igniting.
It is prohibited to leave the workplace with the device running.
When igniting a propane burner, you must first turn the valve half a turn and vent the device. After this procedure, you can ignite and adjust the power and flame length.
It is necessary to extinguish the gas burner in several stages: first, turn off the gas supply, second, lower the locking lever.

In the repair of roofing coverings with the need to use hot air and even fire, it is often necessary to melt bitumen, melt the underside of roofing material and even solder the edge metal sheet. And for this we already need special tools. But why not just set the same roofing felt on fire with a homemade torch if our goal is to melt the bitumen?

The fact is that you won't succeed this way. How do you direct the fire in the right direction, especially when there is wind? And how long will such torches last, since the work of laying the roof will be serious? These two main functions are performed by a gas burner. And now we’ll tell you how to choose it.

A gas burner is an indispensable thing when repairing a roof. It not only lays sheets of roofing felt, but also heats up the mastic and even seals small seams and holes. Here full list all operations:

Cutting and soldering of metal elements.
Removing the old layer of paint.
Sealing small cracks.
Melting mastic.
Heating sheets before laying.
Strengthening butt seams.

A typical roofing gas burner consists of a comfortable handle, a tube that supplies gas, and a metal cup at the end. A hose is connected to a special connector on the handle, and it receives water from the cylinder. required quantity gas And you need to regulate the pressure through the valve on the reducer.

In practice, everything is simple: we press the handle lever, the gas enters the hose, and at the outlet of the glass, a combustion of a mixture of gas and air is formed, which we first ignite with a match. The flame temperature is so high that it can reach 1500°C! Using a valve, you can regulate not only the strength of the flame, but also its length.

Conventional gas burners are light enough - within 1-1.5 kg - so that you can easily hold them in your hand and not drop them from fatigue. And the role of the glass is precisely to shape the flow of flame in the desired direction. The design of the glass is precisely shaped in order to maximally protect the flame from being blown out by the wind. Moreover, both the glass and the pen different models burners are made differently. Although they have the same operating principle: starting a gas burner is no more difficult than a kitchen burner - using an ordinary match or lighter.

Almost all modern gas burners for roofing provide a means of adjusting operating modes: standby mode and operating mode. The standby mode is designed specifically to save fuel.

Different models of modern gas burners differ from each other primarily in the principle of mixing air into the gas. Older burners are connected to an oxygen cylinder, while modern ones can take air from the atmosphere, which is more convenient, of course. Even the gas the burners use can vary. There, most often propane is used, but there are also units that run purely on methane. But we will also note other differences, based on which you can make the right choice.

Standard gas burner in action:

Which is better quality: professional or budget?

So, professional contractors purchase usually expensive professional gas burners that are reliable and safe to use. But for the home craftsman to equip and repair his own roof suitable for home and small handy tool without additional claims. Will the quality of work be worse? Not at all! This type of gas burner is simply not suitable for industrial work, where it is used almost every day and where uninterrupted processes and absolute safety come first.

It is also not acceptable to have a situation where a team goes to a new facility (and, of course, deadlines are definitely running out), and the burner is defective. There is neither time nor reserve to stop everything and go out to purchase new equipment. Whereas with careful handling in the hands of home handyman even the most Chinese unit will serve faithfully for decades. Especially if you use it no more than once a season.

And in the end, when working with a massive professional burner or with a regular one, you will get the same result. But no matter how expensive and professional the gas burner is, before each use, be sure to check its connecting hose, the tightness of the connections and the clogging of the mouthpiece. Such problems do not occur often, but if you miss a defect, there is a risk of serious consequences.

Although, if you have an idea to buy the cheapest “lighter” (how much does it cost to cover a garage roof?), then we will hasten to dissuade you. The fact is that if a gas burner has a weak gearbox, then the fire will be no more useful than the same blowtorch. The work will proceed extremely slowly - while you heat one part of the sheet, the second will already have time to cool down. As a result, you will simply have to remove the gearbox and work without it at your own peril and risk.

Which is safer: compact or large?

At first glance it seems that it is dragging gas cylinder on the roof - the most dangerous idea. Moreover, today you can purchase more compact versions of gas burners:

But in fact, it is precisely these cans that can cause burns and even fire. We are talking about counterfeit Chinese products, which are abundant in the construction market. The large cylinder is still located far from the active burner, while the small cylinder is constantly in the zone high temperature, which is not at all safe. Decide for yourself!

One more point about safety. When choosing a gas burner for your roof, try to avoid counterfeits and overly cheap products - this is simply unsafe. So, the most common problem with such burners is that the operating pressure may be indicated in the technical data sheet as 0.05-0.08 MPa, but in reality it turns out to be up to 1.6 MPa, as in any propane burner. But the supplied gearbox is not at all designed for such parameters, and a closed valve may not withstand the pressure directly on the roof. Such a burner requires a gearbox, but an inexperienced user may simply not know about it.

Which is more convenient: long or short?

If you value ease of use, then purchase a lever roofing burner, in which you do not need to constantly tighten and unscrew the valve. But how long should the handle be?

Thus, the length of the burner is not a style, but an important functional point: short ones, which do not exceed half a meter in length, are usually made partial renovation, heat up individual areas and melt the required areas of the roof. But for larger-scale work, you will need a burner with a length of at least 80 cm.

Overview of market offers

Gas-air burners are the safest of their kind. Easy to use, lightweight and creates a flame of sufficiently high power. But modern market also offers more standard options that operate without oxygen. Choose the one you feel most comfortable working with:

GG-2U: comfortable and light

GG-2S: against strong winds

And this is already professional equipment. This burner runs on propane and differs from previous models in that it works great in strong winds. The whole secret is in its structure - two valves and two housings, with which it is easy to precisely regulate the operating mode.

GGS1-1.7: universal option

This model is considered universal in the construction world due to its light weight, size and high level of performance. It is convenient for drying roofs and fusing soft materials. If necessary, it is easy to create an intense flame up to 400°C, which is especially valuable in repair work. But such a burner can only be used on horizontal sections of the roof.

GGK-1: for precision repairs

This model features a heavier and more durable glass for burning old paint and waterproofing the roof. Perhaps this is the most convenient model for repairing the roof, especially since gas is supplied to it using a lever.

GGS 1-1.0 burners are well suited for minor works, especially repairing junctions, but can also be used for laying waterproofing. But the GGS-1-0.5 series pleases with economical fuel consumption.

GGS-4-1.0: four bells

And for professional installation of roofing materials, the GGS-4-1.0 model is used, which is equipped with four sockets at once and can heat the entire roll at once - all that remains is to quickly roll it out. Significant savings of time and effort! Moreover, it is easy for even one person to cope with such work, but for the repair of just one or two roofs of private houses there is no point in purchasing such equipment.

GV-3: for repairing metal roofing

This propane torch is specially designed for heating metals and manually soldering them, its glass is only 50 mm in diameter.

GV-111R: for stripping

Another popular gas burner is GV-111R. It is especially convenient for repairing roofs with old paint that needs to be removed, and for melting rolled bitumen materials.

GV-550: for junctions

This model is more suitable than any other for repairing roof junction points. The maximum heating of bitumen using this tool is 300°C.

GV-900: heavy fire

The most convenient sample that gives maximum length flame – up to 900 mm. You can work while standing, at full height, which is comfortable for daily tasks.

How to make a gas burner yourself?

Like any other tool, you can also build such a burner with my own hands, if you are confident in your continued safety. But remember, a gas burner is a complex device, and it is important to follow all the rules.

In order to make a torch, you will need a divider and a metal rod - attach them to a handle made of special heat-resistant wood. Borrow a gas supply hose from the gas welding system. And finally, examine the unit for the slightest gas leaks - this is important!

Or everything can be done simpler for small roofing repairs(this turns out to be a fairly powerful burner, note):

Obviously, it is better to buy a ready-made gas burner with all the certificates than to even entrust its manufacture to a friend good master. Just when purchasing, pay attention to the material used to make the burner - only high quality! After all, any burner heats up to a fairly high temperature, and therefore the material must be ultra-strong. Next, look at the handle - it should be equipped with a holder made of durable wood or heat-resistant plastic. This is important if you don't want to get burned unexpectedly while working.

That's all the subtleties!

In the process of roofing work, it is often necessary to use a gas burner. This equipment is used for quickly drying non-flammable surfaces, burning out old paint, heating bituminous materials, etc. Different types of burners are used in construction. For example, a roofing propane burner is often used; burners operating on diesel fuel. Let's take a closer look at the features of this equipment.

A roof burner is a device that generates a flame due to the combustion of a certain type of fuel. Burners are used mainly for heating bitumen components, but can also be used for other purposes. For example, for burning an old layer of paint or for quickly drying a wet surface.

Let's take a closer look at how a roofing burner works, and also get acquainted with the basic principles of working with this equipment.

Types of burners

Today it is possible to purchase burners different types, the main difference between different models is the type of fuel used.

Gas

The most commonly used gas torch is for roofing work. This equipment is a system that includes two elements - a fuel tank and a torch. The elements are connected to each other by a hose. The advantages of this design include:

High level of mobility;
No need to monitor the gas supply level;

Regulators that allow you to control the flame pressure are located directly on the torch.

Advice! In gas burners different manufacturers There may be slight differences in the design of the torches, as well as in the volume of gas cylinders. However, the operating principle is the same for all models.

The gas roof burner has gained wide popularity, first of all, due to the low cost of fuel. However, as when working with any other gas equipment, when using burners you will need to comply with fairly stringent safety requirements.

Propane

A roof burner operating on propane is essentially a gas burner, and structurally it differs little from it. However this type burners dedicated to separate group. The most important difference between propane torches is the ability to use standard gas cylinders, which are used when performing conventional gas welding work.

In addition, propane is safer than natural gas, and propane burners produce a more powerful flame and a higher temperature.

Advice! It is necessary to purchase gas, including propane burners, only from trusted trading companies that guarantee the quality of their products. Working with homemade burners is very dangerous!

Diesel

The diesel roof burner belongs to the liquid fuel class, so its design is different. Inside the torch of such a burner there is a nozzle into which fuel and air are supplied. After ignition, the created mixture forms a flame of a sufficiently high temperature.

Diesel burners are no less mobile and efficient than gas burners. Plus they are safer. Fuel for diesel burners is more expensive than gas, however, since it is consumed economically, the total costs when working with gas and diesel burners are almost equal.

However, diesel burners are used somewhat less frequently than gas burners; even on sale, diesel models are not so common.

Safety regulations

When planning to work with gas burners, you should first familiarize yourself with the safety rules:

When working with any type of burner, you must use special clothing: thick trousers, shoes with non-slip soles, and protective gloves. To work on the roof, it will be necessary to use other devices - a mounting belt for comfortable carrying of tools, walking bridges, etc.
Before starting work, it is necessary to carry out an external inspection of the equipment - burners, gas cylinders, hoses. If defects are identified, it is necessary to refuse to carry out work until the malfunction is eliminated.

When working with a gas burner, it is allowed to keep only one (working) gas cylinder at the workplace. Additional cylinders will need to be lifted to the job site as needed. Empty cylinders are immediately removed from the site.
During operation, it is necessary to constantly ensure that the connections between the hoses and the burner and the cylinder are airtight.
When lighting the burner, make sure that the flame is directed away from people, the gas cylinder and connecting hoses.

When igniting a propane burner, open the valve half a turn. Once the flame has lit, you will need to adjust its length.
It is not allowed to leave the work site while holding a lit torch in your hands. It is strictly forbidden to climb the scaffolding with a burning torch in your hands.
In order to extinguish a gas burner, you must first turn off the gas supply and only then lower the flame lock lever.
Even during a short break in operation, the burner must be extinguished.

Stages of working with a roof burner

When laying fused rolled materials on the roof, it is impossible to do without using a roofing torch. The installation work takes place in several stages:

First you need to prepare the base well. The roof surface is thoroughly cleaned, and if necessary, the base is leveled by screeding.
Then sheets of material are rolled out over the roof, positioning them so that they overlap with a width of 9 cm.

After making sure that the sheets of material are lying correctly, the material must be rolled up again. The extreme part of the material is fixed at the edge of the roof.
Then they begin to warm up the lower part of the roll, gradually unrolling the roll and rolling it with a heavy hand roller.

When laying roll material overheating must not be allowed. It is important to ensure that only the lower part of the roll is heated, and all layers of material should not be allowed to soften.
Modern deposited materials have a protective film on the bottom. During storage of the material in rolls, this film protects the layers from sticking together. When laying, pay attention to when on the surface of the material protective film will burn out completely. At this moment, the heating of this area is completed, since the bitumen layer has reached the optimal temperature.
After installation is completed, it is recommended to additionally heat the joints of the material and roll them again with a roller.
Working with gas burners is allowed at temperatures down to minus 15 degrees. If it is necessary to work in frosty conditions, then liquid fuel burners running on diesel fuel should be used.

So, roofing burners are devices that are necessary for carrying out a whole range of roofing work. Most often, gas burners running on natural gas or propane are used, but when low temperatures they are replaced by diesel burners.
