Gas burner for roofing work. Design and principle of operation of gas burners. Step-by-step burner manufacturing process
In progress roofing works Often you have 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 propane roof burner is often used, and burners running on diesel fuel are often used. 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 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 observe sufficient strict requirements safety precautions.
Propane
A roof burner operating on propane is essentially a gas burner, and structurally it differs little from it. However, this type of burner is classified as a separate group. The most important difference 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
Diesel burner roofing belongs to the liquid fuel class, so the 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 don't occur that often.
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.
- Not allowed to go beyond work site holding a lit burner in his 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 along 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 section is completed, since bitumen layer 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 operating on natural gas or propane, but with low temperatures they are replaced by diesel burners.
Today, there are two technologies for laying rolled waterproofing materials, both have their strengths and weaknesses.
For the hot method, you need to use gas burners; you can buy them ready-made or make them yourself.
Regardless of the specific type, all burners operate on the same principle. Gas is supplied from the cylinder through an oil-resistant reinforced rubber hose. Constant pressure values are provided by a reducer; if desired, the parameters can be adjusted with a special bolt on the top cover of the device. The volume of fuel is regulated by a tap. The rubber hose is placed on the metal tube of the burner and screwed tightly with a clamp. The burner has special holes along the entire perimeter, air flows through them to mix with gas.
The flame is ignited and a metal nozzle is directed towards required area. Old samples of heating pads are set on fire manually matches or lighters; modern models have piezoelectric elements for remote and safe ignition.
The design of the burner ensures a stable flow of flame; it is not blown out even by very strong gusts of wind. Such burners are used not only during roofing work. Sealing of metal pipelines, some road works, etc. cannot be done without them.
What are the advantages of a modern industrial burner?
- Small mass. The weight of the device does not exceed 1.5 kg, which greatly facilitates the work. The roofer's hand does not get tired; he has the ability to heat up the bitumen at the same speed. Achieved optimal temperature the entire area, the quality of the roof covering improves, and productivity increases.
- The gas supply valve and reducer allow you to smoothly regulate the intensity of the flame. The torch changes without stopping the operation of the device, the master makes a decision during installation, taking into account the actual condition old surface flat roof.
- At the most modern models There is special devices, excluding direct contact of the heated burner with rolled materials or the base. Touching a very hot burner to the membranes can cause a complete breakdown of their tightness, which is considered a defect. Such areas need to be repaired, and this takes time and money.
Types of industrial gas burners
The technical parameters of devices depend on their purpose; you must choose the one that the best way suitable for a specific job.
| Type of gas burner | Purpose and brief description |
|---|---|
| GG-2 | It belongs to the small class, has a small length and nozzle diameter. Used to facilitate welding flexible roofing V hard to reach places. Consumes a small amount of gas. |
| GG-2S | An upgraded device with improved combustion parameters. To expand the scope of use, it is equipped with spare burners various diameters and length. The master has the ability to change them as necessary to achieve the required bitumen heating temperatures. |
| GGK1 | Durable housing, used by professionals. Can withstand long cycles and is not afraid of overheating. A reinforced burner has increased weight - this is one of the disadvantages of the device. |
| GGS1-1.7 | The nozzle is located at a great distance from the control handle - making work easier, you can take the most comfortable body position. The gas supply control valve is made of wear-resistant materials, the seals completely eliminate gas leaks, which significantly increases the safety of roofing work. |
| GW | Models GV-900 and GV-550 are produced. They differ in length, the first model has dimensions of 90 cm, the second 55 cm. During fusing of the roof, you can change the units taking into account the distance to the base. |
If the gas burner is manufactured by a licensed enterprise, then it fully complies with existing regulatory documents on safety. It is strongly recommended not to purchase cheap counterfeits; ignition of the units during work causes very severe burns.

How to make your own gas burner
Not everyone can do it, you need to have soldering and welding skills, be able to work on metalworking machines, and have metalworking tools. For manufacturing you will need a piece of pipe for the nozzle with a length of 110 mm and a diameter of 50 mm.
Sizes may vary slightly, but not within wide limits. As practice shows, such a nozzle produces a sufficient flame to heat the roof and consumes a moderate amount of gas. The nozzle is fixed to the handle with metal strips; they can be welded or fastened with rivets. The second option takes more time, but is characterized by increased reliability. Riveted joints do not respond to repeated heating to high temperatures, welding seams crack over time under such operating conditions.
Gas is supplied to the burner by a copper or metal tube. It is advisable to choose a copper one; you can solder a nozzle to it, without having to cut a thread inside a metal tube for it. This makes the work much easier.
One of the main elements of a gas burner is a nozzle; its diameter should be 0.75 mm. This parameter is written on the front surface. You can buy a nozzle in a store, the second option is to unscrew it from an old gas stove.
The hoses are placed on the tubes, the diameters are selected individually.
To solder copper, you need a borax, a copper-phosphorus rod, and a small gas burner to heat the metal.
Step 1. Take a die and cut a thread on the nozzle. If you already have it, great, less work. Work with the die very carefully, the nozzle is thin, and copper does not have much strength. Be sure to lubricate the surfaces with machine oil or soapy water. The movement of the die must be reciprocating.
Step 2. Solder a small fitting of a smaller diameter into the tube. This must be done in this order.
- Prepare workplace. It's better to use for this fireclay bricks, they do not allow heat to pass through, the metal does not cool as much. In addition, fireclay bricks are not afraid of prolonged exposure to an open flame.
- Use a torch to heat the tubes until dark red. More is needed, overheated copper loses its initial properties, and this has Negative influence on her physical parameters. Tear evenly around the entire circumference of the joint with a margin of length.
- Grab some borax with solder and start soldering, constantly maintaining the temperature of the tubes within the required limits.
- Gradually rotate the tube as you solder. Carefully ensure that there are no gaps, you must achieve complete tightness. The seam should be smooth, avoid the formation of drips.
- Check the quality of welding along the entire perimeter, turn the tube. If you have problems with sealing, apply a second layer. There is no need to save solder - big problems may arise later.
In the same way, weld a fitting for connecting a rubber hose on the other side of the tube.
Important. After the tube has cooled, thoroughly blow it away from scale and slag. Tap the surface with various sides, use a compressor, etc.
If this is not done, then during operation small particles will clog the nozzle nozzle. The fusion of the roof will have to be stopped, which will affect the tightness of the roof. The nozzle can only be cleaned after the burner has completely cooled down. And this takes time.
Step 3. For improvement appearance You can remove large deposits of solder using an emery machine. But this is optional, correct process soldering gives a very smooth seam.
Step 4. Screw the nozzle back into place and check the tightness of the connection. Use your finger to close the nozzle and blow strongly into the open end. If there is a leak, a drop in air pressure is felt. Then you need to tighten the threads, if this does not help, then moisten all connections with soapy water and blow again. Soap bubbles will appear in places of leakage; they need to be soldered again.
Step 5. Insert the prepared tube with the nozzle into the nozzle, with opposite side put on the hose. To increase the strength of the structure, first place clamps on the metal strips. With their help, they will be tightly pulled together, the burner will be very stable.
Step 6 Tighten the clamps. It is not necessary very much yet; the distance of the nozzle to the burner will have to be adjusted during the test.
- Main copper tube. External diameter 12 mm, internal 8 mm. The length depends on the purpose of the burner.
- Nozzle. Wall thickness 3mm, length 110mm, diameter 50mm.
- Metal strips. Width 10 mm, thickness 2.5 mm.
- Outer diameter of the tube for the nozzle 8mm, interior 6mm. It just fits her thread. If the factory thread on the injector is inch, then it is better to convert it to metric.
- On the other side of the tube is soldered fitting tip from a gas cylinder. With its help, the gearbox is fixed; it fits the diameter of a standard rubber hose.
- High pressure hose With internal diameter 9 mm. It is sold in specialized stores; you can purchase any number of meters.
Practical advice. Each technological stage is very important and affects the safety of its use. Always keep this in mind.

Requirements for using the burner
Working with an open flame is considered hazardous to health and only adults are allowed to do it.
While working with a burner, a worker may be affected by the following unfavorable factors: fire or ignition of roofing material, cylinder explosion, thermal injuries, bitumen vapor poisoning, excessive fatigue due to an uncomfortable position. To protect against these risks, special measures must be taken; each employee must undergo training and instruction at the workplace. It is strictly forbidden to work with a gas burner while intoxicated; any violation of safety rules must be stopped as soon as possible by management.
Before starting fusing, you need to clear the workplace and provide a specific location for the cylinder and flammable roofing materials. Nothing should interfere with free movement; accidental falls should be avoided as much as possible. If there are doubts about compliance with safety requirements, work should not begin until complete elimination problems.
In case of emergency situations you need to call a doctor as soon as possible and provide first aid. In case of burns, the damaged areas should be watered clean water. It is strictly forbidden to lubricate them with grease, oil, petroleum jelly and other folk remedies. Do not touch such places with your hands, and do not open bubbles with liquid. After an emergency occurs, all work on the roof is stopped completely until the relevant services arrive.
After completing the sealing of the roof, you need to put everything in order: clean up after yourself construction garbage, sections of roofing, etc. The burner must be checked and cleaned; if there is damage, then repair or replacement is carried out immediately. If it is not possible to repair the device, then you must remember this. Equipment and equipment must be stored in special places, access to them by third parties is limited.

Video - Do-it-yourself fused roofing
Gas burners are used for fusing waterproofing materials on flat roofs of various buildings and structures. What roll material is suitable for performing such work, its brief specifications And practical advice – .
When carrying out roof installation and repair work, situations arise when heating or drying of the material is necessary - for example, when laying a layer of waterproofing or constructing soft roof when you need to heat up bitumen-based mastic. For these and many other purposes, a portable roofing gas burner is used.
Using this device, you can perform several types of operations:
- drying surfaces;
- cutting or soldering of metal elements;
- firing the old layer of paint;
- other work that requires heating to high temperatures.
Design and principle of operation of the burner
Roof burner is a metal-based glass equipped with a nozzle and plastic or plastic attached to the body wooden handle.
The design of the gas burner glass is designed in such a way that the flame is protected from being blown out by the wind.
Gas enters the housing through a special gas hose. Propane supplied under pressure is mainly used. The burner has a valve to regulate the amount of gas supplied. In addition, it is also possible to adjust the flame length.
In order to save gas consumption, roof burners have a special gearbox that controls fuel consumption.
Absolutely all burner models are equipped with an atmospheric air suction system.
To start the burner, use regular matches or a lighter.
Gas burners also provide a device for regulating operating modes. For example, most models have a standby mode, the purpose of which is to prevent wasted fuel consumption during breaks in work.
Since roofing burners heat up to very high temperatures during operation, only heavy-duty materials are used for their production.
The length of the handle for holding the burner should be no more than a meter. The device itself is very light: its weight ranges from 1-1.5 kilograms.
To prevent burns, the burner handles are equipped with a holder made of very durable wood or heat-resistant plastic.
It should be noted that liquid fuel burners that run on fuel oil or diesel fuel can also be used for roofing work.
Stages of work when laying material using a roofing torch
If as waterproofing material Roofing felt is used; there is no way to do without a gas burner. It is also necessary for covering the roof with modern built-up types of materials.
The entire process of working with the device can be divided into several stages.
- First you need to prepare the base for further laying of the material. For this purpose, it should be cleared of debris. If necessary, you must also level the surface using concrete screed.
- After this, the rolled material is rolled out over the entire surface so that adjacent sheets form an overlap with a width of 85 to 90 mm.
- Having completed the leveling and marking, the rolls must be rolled up again and strengthened at the base of the roof using a torch. Heating the lower part of the roll and the base of the roof using a burner flame, the material is slowly rolled out, pressing it to the base.
To avoid the formation of folds and air bubbles, you need to run a hand roller along the attached canvas. At the final stage of the work, a roofing gas burner is used to heat the seams of the overlapping material. After this, the seams should be rolled again using a hand roller.
During operation gas burners There are a few important points you need to know:
- The use of this device is possible with temperature conditions not lower than minus 15 degrees;
- if work is carried out at a lower temperature, then you can use a burner at liquid fuel;
- when using a gas burner to lay roofs with high quality characteristics per day you can lay from 500 to 600 m of roofing material;
- since the work is carried out under open air, the gas burner must provide a stable flame supply and reliably protect it from being blown out by the wind.
Roof burner models
To carry out roofing work, burners of different models are used.
GG-2– name of the propane roof burner model. The most suitable sample for self-taught craftsmen who carry out repairs with their own hands. Despite its high quality, it has a fairly reasonable price.
GG-2U has similar characteristics. Distinctive feature This model is a shortened version of the gas supply tube. It is ideal for carrying out work in hard-to-reach parts of the roof, as well as for gluing abutments and joints.
GG-2S belongs to the series professional equipment. This model runs on propane. Its main advantage is that the device can be operated even in strong winds. The device consists of two valves and two housings, and this makes it possible to regulate operating modes with great accuracy.
GGS1-1.7– low weight, size and high degree of performance make this model almost universal. It is used to dry the roof and fuse soft roofing materials onto it. It is also successfully used in waterproofing and some other types of work that require a high-intensity flame to bring the surface temperature to 400 degrees.
The burner can be used to carry out work on horizontal sections of the roof and on junctions.
GGK-1– propane-air model. Its difference is a heavier and very durable glass.
This model is suitable for firing old paint, wooden surfaces, for carrying out waterproofing work. Gas is supplied using a lever.
GGS1-1.0 is used for minor works small volumes, arrangement of junctions. Suitable for use on roofs with large angles tilt Also suitable for laying waterproofing.
GGS1-0.5 used for small repair work on the roof. It features economical fuel consumption.
Model GGS4-1.0 is equipped with four sockets, which allow simultaneous heating of the roofing material over the entire width and non-stop rolling of the roll.
Thanks to the presence of special hooks on the edges of the device, heating and rolling out the roofing material can be carried out by one person. Using this model, you can significantly increase the productivity of work performed and reduce fuel consumption.
GV-3– a propane torch designed for heating metals, welding them, as well as manual soldering. The diameter of the glass is 50 mm.
GV-111R used for melting rolled bitumen materials, burning a layer of old paint.
GV-550, GV-900– very easy to use samples. They differ from one another in the maximum flame length. The second model makes it possible to work while standing, in full height, since the length of its torch reaches 900 mm. The first model (GV-550) is more suitable for carrying out work at roof junction points.
The GV model is suitable for heating non-ferrous and ferrous metals, melting rolled bitumen materials when carrying out waterproofing and roofing work, as well as a number of other works that require the use of exclusively propane flame.
GV 500 used for welding work during the laying of roofing materials. It can be used to melt bituminous materials. This model can heat the processed material up to 300 degrees.
GV-850– a propane burner equipped with a special valve that makes it possible to precisely regulate the amount of technical gas supplied from the cylinder. The model also has a lever with which the welder controls the length of the flame. This type The gas burner does not operate on pure propane, but on a mixture, part of which is technical oxygen.
Safety rules when working with gas burners for roofing
When operating gas burners, safety rules must be strictly observed.
- To carry out roofing work, you need to change into special clothing and shoes with non-slip soles. You will also need some additional devices: walking bridges, a belt, etc.
- Before starting work, it is necessary to conduct a thorough external inspection to ensure that gas burners, cylinders, and connecting hoses are in full working order.
- During operation of the gas burner, only one gas cylinder may be present at the workplace. During work, you must carefully monitor the tightness of the connection of cylinders and reducers with hoses.
- Do not stand in front of the nozzle while lighting the burner. The direction of the burner flame must be such that it does not affect nearby people, the gas cylinder and connecting hoses.
- When working with deposited materials, care must be taken to ensure that they do not overheat or ignite. When heating the material using this device, it is necessary to ensure that only the lower part of the canvas melts. The entire thickness of the material must not be allowed to soften.
- The burner should not be ignited by accidentally igniting objects. For this purpose, you can only use matches or a lighter.
- When using a propane burner model, the valve does not open a full turn, but halfway. After waiting a few seconds, the mixture can be ignited, and then proceed to adjust the flame length.
- A worker with a lit burner in his hands has no right to go beyond the boundaries of the workplace or climb scaffolding.
The gas burner is extinguished in two stages:
- shut off the gas supply;
- lower the locking lever.
If there is a short break during operation, the burner must be extinguished. If a longer break is planned, the gas supply to the cylinder must be stopped.
If the input channels of the mouthpieces are clogged, the device cannot be used, as backlashes and pops may occur.
If a backfire occurs or the burner overheats, you must immediately stop working and turn off the gas to the cylinder. The device itself should be cooled by immersing it in a container of water.
CONCLUSIONS
- A gas burner is a device that is necessary for certain types of roofing work.
- At its core, a gas burner is a metal glass with a nozzle and a handle.
- There are many different models of roof burners. The choice is made in accordance with the type of work performed.
- When using the burner, you can adjust the amount of gas supplied, flame length and fuel consumption.
- When working with a gas burner, you must strictly follow the instructions and observe safety rules.
How the process of fusing roofing material using a gas burner is carried out can be seen in the video.
The installation of soft overlay roofs from roll materials is carried out using a fireless method using solvents or a fire method, which requires a roofing torch. Using this equipment, the covering mastic layer is melted. When installing a new roof and repairing an existing flat roof, units are used that run on gas (propane-butane), liquid fuel (solar oil) and electricity. Burners are used to dry surfaces, solder and cut metals, burn old paint, and also carry out many other works that require spot heating to high temperatures.
A manual gas torch for roofing work is made in the form of a metal cup equipped with a nozzle and complemented by a plastic or wooden handle securely attached to the body. The design of the burner bowl does not allow the wind to blow out the flame. Pressurized gas is supplied to the housing through a gas hose. The burner has a valve with which the worker regulates the amount of supplied gas mixture. The tool is also equipped with a device that regulates the length of the flame. A special gearbox is responsible for economical gas consumption. Almost all types of roofing burners provide for air suction from the atmosphere; the equipment is put into operation using a lighter or match.
The burner design also includes a device that allows you to adjust operating modes. In many models, during technical breaks, a standby mode is activated to prevent wasted gas consumption. Since a gas burner heats up to the highest possible temperatures during operation, manufacturers use only high-strength materials for its manufacture.
Important!
The length of the handle by which the worker holds the burner should be no more than one meter. At the same time, it is provided with a holder made of heat-resistant plastic or high-strength wood, which serves to protect the master’s hands from burns. The tool weighs only one and a half kilograms, so a person with any physical characteristics can work with the burner.
Oil burners
The design of burners operating on fuel oil or diesel fuel differs from gas tools. In a liquid fuel burner, fuel is supplied to the chamber under high pressure, so the liquid is sprayed in the form of tiny particles. The fuel, sprayed in the air, is ignited at the exit of the chamber nozzle and forms a stable flame.
Important!
The advantage of a diesel burner over gas equipment is that the tool can be used even in severe frosts.
The diesel burner allows you to carry out work even in cold winters
Roof burner models
Gas roofing burners can be used to perform hot work when installing soft fused roofing various models, For example:
- GG-2 is recommended for use by amateur craftsmen at home when carrying out roof repairs in small quantities.
- GG-2u has the same technical characteristics as the GG-2 model, differing only in the presence of a shortened gas supply tube. The tool is indispensable when working in hard-to-reach places, as well as when gluing joints and junctions.
- GG-2S is a professional equipment. Withstands high wind loads, which is important when installing roofs multi-storey buildings. Design feature This model is the presence of two housings and two valves, allowing for more precise adjustment of operating modes.
- GGK1 has a heavier glass, characterized by increased strength.
- GGS1-1.7 is considered a universal model, different from others professional models burners with low weight and high performance.
- GV-900 allows the worker to work at full height because it creates a torch maximum length(900 mm).
- GV-550 forms a torch 550 mm long and is intended for fusing roofing material at junction points.
Important!
Burners operating on liquid fuel include the GRZh-1 model.

Installation of roll fused roofing materials
Installation of a soft fused roof using the fire method is divided into the following stages:
- Preparing the base roof base for laying the material. In this case, the surface is cleared of debris and leveled, if necessary, with a concrete screed.
- Rolled material is rolled out over the prepared roof area, making sure that adjacent sheets overlap each other by 85-90 mm, forming an overlap.
- After fitting, alignment and cutting, the rolls are rolled again.
- The rolled material is strengthened at the base of the roof, and it is better to use a hand torch.
- Then the worker uses a burner flame to heat the surface of the roof base, which has been treated in advance with a primer, as well as the lower part of the roll. The second worker slowly rolls out the roll and presses the material tightly against the base of the roof.
- The reinforced fabric is rolled with a hand roller and care is taken to ensure that no folds or air bubbles form.
- If seam delamination is detected, additional heating of the material in these places is carried out, followed by rolling.
A gas burner heats the base and bottom layer of the rolled material
Important!
The gas burner for roofing work is operated at subzero temperatures not exceeding 15 degrees below zero. On colder days it is necessary to work with oil burners.
Subject to the use of professional equipment that provides high quality fusing the roof, up to 600 meters of roofing material can be laid in one working day.
Compliance with safety regulations
Working with any gas equipment requires strict adherence to safety regulations. In this case, roofers must be equipped with overalls and safety shoes with non-slip soles. At heights, the worker is protected using a belt. Only serviceable equipment is used. It is not allowed to simultaneously place several gas cylinders on the roof during work. Pay attention to the tightness of the hoses connecting the burner to gas cylinder.
When working with roofing torches, it is necessary to strictly observe safety precautions.
There are many other restrictions that should be taken into account when installing a built-up roof. Engage only those companies that perform work in accordance with established rules and construction standards.

Carrying out roofing work or repairing old coverings involves laying materials and melting mastics using a special device. A gas burner for roofing allows you not only to heat the material to the desired temperature, but also to dry its surface.
Such devices are also used to perform a number of other tasks:
- heating any workpieces and products to the required temperatures;
- cutting and soldering of metals;
- drying surfaces;
- firing old paint.
What kind of equipment is this?
As a rule, a gas burner for a roof is a metal cup with a nozzle and a handle attached to the body. The glass itself is assembled in such a way that the burner flame is protected from wind blowing. The gas enters the housing through the gas pipeline. Propane under pressure is often used for these purposes. There is a valve on the burner itself that allows you to regulate the amount of gas supplied. In addition to the intensity of the flame, its length can also be adjusted.
The propane roofing burner has a special gearbox that allows you to control fuel consumption, thereby reducing the cost of roofing work. In the vast majority of such devices, air is sucked directly from the atmosphere. To start the burner, use regular matches or a lighter.
Modern burners have a device that helps regulate modes. Thus, many models have a so-called standby mode, which allows you to reduce wasted gas consumption during breaks from work.
Since the flame heats nearby elements of the device to high temperatures, gas burners for roofing work are made from high-strength, heat-resistant materials. The length of the handle is often no more than 1 meter, and the weight of the burner does not cause discomfort when carrying out roofing work (up to 1.5 kg). To ensure that the burner operator does not get burned, the handle has a special holder made of wood or plastic that does not allow heat to pass through.
But gas burners for roofing are not the only solution in this segment. Quite often liquid fuel devices are used in construction. They run on fuel oil or diesel fuel. The design of such units itself is slightly different from that described above. In liquid fuel burners, fuel enters the combustion chamber under high pressure, thus turning the liquid into a jet fine particles. At the exit from the chamber, the sprayed liquid is ignited, which creates the effect of a stable flame. A diesel roof burner has an advantage over a gas burner in that it allows you to work even at low temperatures.
Stages of work when laying material using a roofing torch
The entire work process can be divided into several stages:
- preparation of the base. For these purposes, it is necessary to clear the base of debris and, if necessary, level it with a concrete screed;
- rolls out across the roof area roofing material. In this case, an overlap of 8-10 cm is maintained. After aligning the strips of material and applying markings, it is rolled back into rolls, while securing the beginning of each strip to the base;
- A gas burner for roofing is used to heat the bottom of the roll of material and the base of the roof. Then the roofing material is carefully rolled out, pressing it against concrete surface;
