Installation of master flash on sloping and straight roofs made of metal tiles, ondulin, corrugated sheets: types, step-by-step installation instructions

One of the most difficult components is the passage of a chimney through a roofing system. It is necessary to create high tightness and also eliminate the possibility of fire. In order for the goal to be achieved, many actions were taken at one time, and only professional roofers got down to business. If problem areas were found, they were filled with asbestos, roofing felt and tin were fixed, and cement mortar was used. Despite the difficult process, all this did not last long, since no one canceled the temperature and atmospheric effects. To significantly facilitate the work and extend the service life, we created the roofing “Master Flash”. It will allow you to avoid complex and lengthy procedures. Master Flash will provide protection from precipitation, while spending less effort, time and money.

Master Flash for a chimney: types, design and technological installation rules - House and site

The construction of a house, country house or other building of any kind is impossible without the use of ducting through the roof to release air from the chimneys.
To prevent dirt and precipitation from penetrating under the roofing material into the passage area, it is necessary to seal the resulting gap.

The ideal solution to this problem is to use Master Flush on chimneys.

Advantages of Master Flash penetration

Master Flash flexible products have won the trust of craftsmen and, thanks to their undeniable advantages, have become the most popular devices for isolating the gap between the chimney and the roof:

Elasticity. Thanks to its plasticity, “Master” creates a high-strength seal around the pipe and does not leave a gap in the roof.
Versatility. Used for roofs of any slope and shape. The roofing material can be very diverse: slate, roofing membrane, onyulin, metal tiles, profiled flooring.
Fire resistance and resistance to high temperatures. After thermal linear tension, the product acquires its original shape and size. The maximum temperature at which Flash Flash Flash Flash can be used is 230-240 C°. Therefore, rooms can be equipped with heaters operating on all types of fuel.
Condensation. Reliably protects the gap from moisture penetration and prevents the possibility of leaks.
Durability and longevity. Resistance to strong temperature fluctuations, chemical and mechanical influences ensures long-term operation. The manufacturer guarantees the flawless operation of the product for up to 30 years. Typically, replacement is not required during the entire life cycle of the product.
Basic installation. Allows you to install Master Flash even for beginners. The assembly process does not require special equipment or tools.

It should be noted that flexible eliminates the need for additional sealing in the penetration block and can significantly reduce the volume of construction materials and reduce financial costs.

Facing with wild stone

This material gives the house an aristocratic appearance and allows its owner to distinguish his home from the gray and monotonous mass of other buildings

When using facing stone, pay special attention to caulking all seams, especially for interior finishing. But, wild stone is often used as a means of cladding on the outside, giving its natural and presentable appearance. In addition, the wear resistance threshold of such elements is also surprising.

In addition, the wear resistance threshold of such elements is also surprising.

Stone-lined chimney on the second floor.

Marble plaster

This is a crumb where particles of small pebbles are mixed into a solution. Cladding, therefore, is only permissible inside buildings, since the crumb does not like exposure to cold temperatures. It goes well with fireplaces and traditional stoves, especially if the kitchen area is additionally finished with such chips, not to mention brick chimneys.

Venetian plaster

On sale it is a white powder, which must be dissolved in water when applied. If desired, you can add different colors, resulting in a rich selection of shades. Keep in mind that decorative cladding must be carried out on a pre-prepared base - plaster. After application (use a spatula), it is recommended to dry with a hairdryer.

Assembly

The Flash Wizard is installed as follows.

First, cut off the upper part so that the diameter of the resulting part is approximately one fifth less than the chimney pipe. This will ensure a tight fit. The resulting structure is placed on the pipe with the base down and moved along the pipe until it fits against the roof. When installing master flush on corrugated sheets and metal tiles, it is better to use a rubber penetration.

The next step will be to secure the resulting structure with sealant. At the very end, you should screw it to the roof using self-tapping screws.

Master flush, or kryza, perfectly performs the function of protecting the attic from precipitation

There are several tricks when installing master flash.

To make it easier to thread the pipes through the roof, cover them with soapy water.

This will make pulling easier. If you were unable to immediately successfully cut a hole in the master flash, you can try to use it, sealing it tightly with a clamp. When buying a sealant for master flush, make sure that it is resistant to moisture. There should not be too many self-tapping screws, since in any case the sealant will someday begin to let moisture through, and then it will seep through the holes. Try not to screw self-tapping screws into recesses in the roofing material, as this is where precipitation flows. When installing the master flush on a chimney ridge, place its top under the flashing.

There are some features that you need to know before installing master flush on metal tiles. And other roofing materials that are installed with one sheet overlapping another. When performing installation in this case, you need to bring the upper part of the canopy under the nearest adjacent sheet. By performing this maneuver, you will achieve free flow of liquid regardless of the tightness of the penetration connection. This way you can increase the service life of the connection.

If you use a chimney without insulation, as well as boilers running on solid fuel, temperatures can reach 600 º, which can lead to failure of the roof. How to install the master in this case? You need to select a pipe whose size exceeds the diameter of the chimney by about 10-12 cm. Its length should be up to 50 cm, or you can use regular galvanized metal. In the place where the chimney passes through the roof, it must be covered with basalt, and a selected sleeve must be placed on top. The master flash is installed, the dimensions correspond to the sleeve used. The open section of the insulation at the top is covered with a hopper, which is made of galvanized steel. You can attach it using a clamp.

The canopy with fastener is installed according to the following scheme. The top of the cone is also cut to a size 20% smaller than that of the pipe. Then the clasp is removed from the lock. The cuff is wrapped around the pipe, its sides are connected. Then the fastener returns to its place, the teeth tighten. The sealant is then applied to the appropriate area of the roof. Then the fastener and all places that need to be insulated are treated with it.

Having completed the installation, install the plate, thus giving the structure a finished look.

Thus, installing a master flush with your own hands is completely easy to do even for a novice, inexperienced builder. After all, all the tools needed for it can be easily found in many construction stores or even made with your own hands. This will not require special time or material costs from the master. At the same time, the installation of such a device will reliably protect the roof from precipitation, which otherwise could lead to unpleasant consequences.

Expert advice

The construction of a proper chimney system is the basis for the efficient and safe operation of heating equipment. If you plan to assemble it yourself, then advice from masters - professionals in this field - will not be superfluous.

Subtleties of switching from a brick pipe to a sandwich

At the point of transition from a brick pipe to a sandwich, it is better to install not a homemade, but a ready-made metal adapter. Its lower part corresponds in size to a brick channel, and the upper part has a round shape with a diameter equal to the diameter of the sandwich. A reliable heat insulator is already installed inside. The use of this device ensures the necessary tightness and fire safety of the connection.

Subtleties of passing through a wooden roof

When using ready-made polyurethane foam, it is necessary to take into account that wood can expand at high humidity, so there should be a small gap between the walls of this device and the opening, approximately 3 - 5 mm. In addition, it is important to impregnate the wood in the joint area with anti-friction agents, which increase its fire resistance.

Where is the best place on the roof to install the pipe?

It is better to move the place where the pipe exits through the roof slightly from the ridge to one side. If it passes through the ridge, then when installing the passage unit, it will be necessary to violate the integrity of the rafters and the ridge beam.

About the conditions of use

An elastic rubber penetration would be an excellent option for ensuring reliable waterproofing in the chimney passage area. But it will not be appropriate in all cases. Experienced experts say that such a device is suitable for equipping the following smoke exhaust channels:

Sandwich chimneys. These pipes have two contours made of durable galvanized steel, between which there is a layer of thermal insulation, most often represented by basalt fiber. This material retains heat through the inner pipe, which is why the outer part of the chimney does not warm up much, remaining practically cold. Optimal waterproofing of sandwich pipes - rubber models.
Stainless steel chimneys, through which combustion products are discharged into the external environment when heating premises, are distinguished by the fact that they heat up very much. It is customary to fill the gaps between them and the roofing surface with heat-resistant penetrations made of silicone. In this case, master flush rubber models are also suitable, but if the chimney is powered by a gas condensing boiler.

Penetration sealants.

To install this “Master Flash” device, owners of private houses must select a suitable hermetic adhesive. Which sealant is best suited for these purposes will depend on the manufacturer and the quality of the glue. Thermal sealant “Titan” has good reviews; roofing sealant, bitumen sealant “OLIMP” and silicone sealant “STAYER” also have good qualities. Currently, you can study the properties and advantages of sealants for installing Master Flash protection by going to the Internet, where buyers share their experience in installing the device, and also leave various reviews about sealed adhesives.

Installation of roof sealant

Installation of master flash is simple in technology. However, there are some points that need to be taken into account.

On a flexible basis

On metal roofs, cuffs with a flexible base are used. The installation itself looks like this:

Determine the location of the cut. Do not forget that the cutting diameter will be 20 percent smaller than the chimney;
To ensure that the cut part is even, find roofing scissors;
We soap the chimney pipe with soap or moisten it with water. This is done to make it easy to put on the cuff;
The installation is done, then we draw lines along the edges of the base;
We lift the seal and apply the adhesive;
We press;
We apply sealant where needed.

Master Flush with hard rig

If there are metal strips at the edge of the seal, then installation is similar to the installation of soft equipment. The following items are added. Before installation, the base coating must be profiled so that it adheres well to the roof. To work, you will need hexagon-shaped self-tapping screws. Fasteners are screwed onto the bottom of the profile.

Seal for repair

A special seal design for roofs with a technological gap is needed when it is not possible to attach a seal to the chimney. They are often used for repair work on old chimneys.

The installation will be like this:

Using strong scissors, cut off the upper cone to less than 20% of the chimney cross-sectional size.
Unscrew the shutter and wrap the pipe.
Align the gap in the seal and close the locking system.
Raise the edges of the base to apply silicone sealant to the roof.
Press everything with force, spread the adhesive solution on the desired areas, the locking system.

Installation on tiles, slate

For tile or slate roofs, seals are made with a lead or aluminum flange. The cone system is also cut off. This is done in order to ensure good adhesion of the remaining cone to the chimney.

The top of the iron base is tucked under the roof, and the bottom and side of the material are placed under the roof. To prevent precipitation from getting under the covering, the top strip must be folded. Upon completion of the work, it is necessary to cover the joints with problem areas with silicone.

We put the master flash on the corrugated sheet

Installation of master flush on corrugated sheets is carried out in the same way as installation on a tile roof.

When installing, remember the following recommendations:

In order for the seal to pass through the pipe easily, you need to coat the pipe with a substance that will support sliding.
If you made a mistake with cutting a hole on the cone, well, you need to throw out the element.
We take waterproof sealant for sealing. We screw screws on top of the sealant. As time passes, the sealant will perform its duties worse. The self-tapping screws will come to work. But, you don’t need to screw in a lot of screws. A large number of holes for screws increases the likelihood of moisture getting inside.
When we place the kriza on the ridge, its top needs to be placed under the ridge cap.
If the pitched covering is not uniform, with overlaps, you need to move the top of the seal under the adjacent part. This action promotes continuous flow of water, regardless of how well the roof sealing is done. This will ensure long, continuous operation.
Installation of master flash on corrugated sheets is carried out similarly to a tiled roof.

Roof penetration sealant made of EPDM (+185 C)

The Master Flash roof penetration is compatible with all types of roofing. Goes well with corrugated roofing surfaces. Made of thermo silicone, EPDM rubber (vulcanized). A huge selection of options for use: cable ducts, ducts, ventilation pipes, chimney pipes.

The roof is reliably protected from water and snow. Guaranteed heat resistance of vulcanized EPDM rubber: +185C

Select Master Flash

Dimensions alone will not be enough to select a Master Flash. There are important points to consider. Bendable cuffs with a rounded and square base are suitable for roofs that are designed for an inclination angle of less than 45 degrees. The roof can be made of roofing steel, bitumen shingles, corrugated sheets and other coverings. The seals are mounted on silicone and then attached to self-tapping screws.

A seal complete with a flange on a flexible basis is used for roofs with a slope angle of less than 60 degrees. If the roof is flat and the slope angle is more than 60 degrees, use a compactor where a base with an increased area is used. Master Flash on sloping roofs is the best option available.

Silicone or bitumen mastic is used to attach cuffs to flat roofs. They are placed perpendicular to the base. If the roof is slate or tiled, use a metal-based seal with an area larger than conventional seals. Master flash on metal tiles is installed in the same way.

In the production of Master Flash they use:

Rubber material of the highest quality, withstanding large temperature changes. The rubber seal lasts much longer;
Silicone, which is not afraid of changes in temperature conditions, holds about 200 degrees.

Characteristic advantages

Elastic protective products, which can be used to easily seal a pipeline passage on the roof, are highly appreciated by craftsmen. They have replaced many traditional materials previously used to seal gaps. Do-it-yourself flash master is a task that even an inexperienced person can handle, and all thanks to certain qualities of the device:

Elasticity. Rubber penetrations are very flexible and fit tightly to the pipe, enveloping it on all sides. Such products fit well even on profiled material, which is used to cover roofs with any slope and various shapes.
Tightness. Reliable protection of gaps is provided from leaks through which atmospheric moisture can enter inside.
Simple and uncomplicated installation. One person can complete the described task in a short time; no additional help is required.
Versatility. Master Flash is installed on roofs covered with slate, metal tiles, corrugated sheets, bitumen shingles and others.
High strength indicators. The structure of the material is porous and quite dense, withstands large mechanical loads.
Durability. Rubber penetrations are not damaged for a long time and do not need to be replaced due to their resistance to chemical environments and temperature changes.
Operation at high temperatures. The maximum permissible value at which silicone insulation for the chimney inlet can work is 240°C. Such heat resistance allows the described devices to be used when equipping heating systems operating on various fuels.

Recommendations

For flat roofs, any “master flush” with a wide, compacted base will do. But for corrugated sheeting, it is always better to choose something more flexible, with reinforcing elements around the perimeter of the fold due to the high edges of the sheet. A dense base will be more difficult to bend and therefore more difficult to ensure a seal.
For roofs with a slope of 45 degrees, a roof with a round or square flange is suitable. For roofs with a slope of 60 degrees, it is recommended to choose penetrations with an elastic base that are much larger in area for better installation.
If there is no corner “master flush” on sale that corresponds to the angle of inclination of the roof slope, then you can purchase a straight one, but with a larger base area. Due to the flexibility of the material and the corrugation of the cone, the tilt will be invisible.

What it is

This device is a base in the shape of a square or circle, in the center of which rings rise, one after another. Moreover, each overlying ring is smaller in diameter than the previous one. In general, the material resembles a cone.

The base can be made of silicone or special rubber. Silicone can withstand high temperatures, approximately 350 degrees. But the melting of ordinary rubber begins at a temperature of 180 degrees. Therefore, in terms of heat resistance, silicone prevails over rubber. But, if you look at the ability to withstand ultraviolet exposure to sunlight, then rubber has an advantage. It does not collapse or deform under the influence of ultraviolet rays, unlike silicone.

But in the case of silicone, this problem can be solved, since there are special devices that will protect master flash from the harmful effects of ultraviolet radiation. The base of the master flush may also include aluminum. This metal gives it strength and promotes uniform pressure distribution.

Estimated cost

The cost of a master flush depends on what material it is made of. If the base is silicone, then such materials are more expensive than those based on rubber.

Prices for silicone wings range from 1,500 rubles to 3,500 rubles per piece. The price depends on the diameter and the size of the material.

Prices for rubber roofs range on average from 255 rubles to 600 rubles per month.

That's all! As you can see, master flush is an inexpensive material. It should be remembered that if everything is done in accordance with the rules, the gap will be closed hermetically, which will further prevent water from entering under the roof.

Also, when working at height, one should not forget about safety rules.

The “Master Flash” protective device is designed to seal joints and prevent moisture from entering; such penetrations are mounted around the chimney pipe and can withstand temperatures of about 300 degrees. The product is endowed with quite good indicators of flexibility and heat resistance, as well as excellent elasticity. The roofing protective element “Master Flash”, due to its technical data, expands when heated and contracts when cooled. The protective penetration has sufficient strength and has a long service life. The penetration is not susceptible to bright sunlight, and is not destroyed by strong winds and various atmospheric precipitations. The Master Flash protective product can be very easily installed at the junction of the chimney pipe and the roofing material. After Master Flash protective products went on sale on our domestic market, the owners of private houses resolved all the problems associated with sealing the roof area around the chimney duct.

Master Flash for a chimney with your own hands - device and installation

Installing Master Flash is a fairly simple process. This was mentioned above. But, there are some nuances that you need to know about.

On a flexible basis

Seals with a flexible base are used on metal roofs.

Installation process:

You need to choose a place for the cut. We must not forget that it should be 20 percent narrower than the diameter of the chimney.
For this you need roofing shears. Try to keep the cut part straight.
The surface of the chimney must be moistened. Then, tighten the seal onto the pipe.
After installation on the roof, you need to draw a line along the edges of the base.
Lifting the seal, apply adhesive.
Press.
Apply sealant to all required areas.

You need to choose an adhesive based on the type of roof covering.

Split roof seals are necessary in cases where it is impossible to fit the insulation onto the pipe. They are typically used to repair outdated chimney insulation.

Using powerful scissors, you need to cut off the top of the cone 20% smaller than the diameter of the pipe.
Open the lock and wrap the chimney.
Connect the cut of the seal and close the lock.
Lift the edge of the base to apply silicone sealant to the roof.
Press everything down and apply glue to the required areas and to the lock itself.

For tile or slate roofs, seals with an aluminum or lead flange are produced. Their cone is also cut off to ensure a tight fit of the cuff to the pipe. The top of the metal base is placed under the roof, the lower and side parts are laid on the roof. To prevent moisture from getting under it, you need to bend the top edge. Finally, you need to fill the problematic joints with silicone.

You can learn about the installation of Master Flash using videos. Basic rules for installing pipe seals.

A distinctive feature of the Master Flash sealing system is its speed and ease of installation. In addition, they will allow you to save significantly, provide reliable waterproofing and last a long time. Another convincing argument is that you can install them yourself.

At the point where the chimney exits onto the roof, a gap forms between them, which, if not eliminated, will lead to moisture getting under the roof. The size of such a gap can be 3-5 cm. Traditionally, bitumen, cement or various sealants were used to eliminate it. However, such protection is short-lived and not reliable enough. To eliminate all these shortcomings, a master flush for the chimney is used. Another name for this device is rat or otter.

What is it needed for

The place on the roof where the chimney goes outside must meet the following requirements:

The space between the edges of the hole and the pipe must be sealed tightly. Otherwise, water will start flowing there.
Corrosion resistance
Resistance to low and high temperatures.
Flexibility.

It is attached with its base to the surface of the roof, and with its rings it envelops some part of the pipe, as a result of which the space between the edges of the hole and the wall of the pipe is hermetically sealed.

Algorithm of actions for the device

The chimney is installed and fixed in the base area.

During the construction of the canopy, it will be necessary to dismantle the pipe canopy, if it was already attached to it.

Next, perform the following steps:

The size of the ring on the penetration is determined. It should be 20 percent less than the diameter of the chimney. Using a sharp knife, cut to the desired size. If the gap is unsuccessfully cut, do not rush to throw away the Master. You should try to correct such a flaw using a tightly installed clamp;
The prepared Master pulls himself onto the pipe and with force lowers himself to the roof level. To make sliding easier, you can use soapy water as a lubricant;
In the case of making a roof covering from ondulin, tiles, slate and other covering materials laid overlapping, the upper section of the base of the otter must be moved under the adjacent, outermost component of the insulation. This will create conditions for free drainage of water regardless of sealing;
A moisture-resistant sealant or bitumen is applied under the base, and the flange is secured with self-tapping screws with a large press cap to the roof and sheathing. The distance between the screws should be maintained at 3.5 cm.

Expert advice: you should not screw in a large number of screws, since over time the sealant will gradually begin to lose its insulating qualities, and moisture will begin to enter through multiple punctures from the screws.

It is not recommended to screw self-tapping screws into depressions in the roofing material through which water flows. The flexible, sealing element can be easily bent to fit the roof profile and attached with minimal gaps. This completes the installation process.

In rare cases, a tight fit of the roof to the pipe is not observed. In this situation, the edges of the seal should be tightened with a clamp. This state of affairs serves as proof that the Master Flush was not selected accurately or the installation was carried out with errors.

Such auxiliary parts can be easily completed and installed with your own hands, or can be purchased at specialized construction stores. Such a “plate” is simply strung on the chimney on top of the otter. The size of the metal pad must be accurately selected to prevent it from oscillating due to wind.

The maximum operating temperature of Master Flash shows that the gasket cannot be used on every chimney. The otter will behave well if the chimney is insulated with a sandwich or on a chimney without insulation, which will heat up to no more than 100 degrees.

Expert recommendation: to avoid unpleasant situations - ignition or melting of the “master” during soot burning in an uninsulated pipe (temperature can reach 500-600 degrees), it is necessary to first perform thermal insulation work on the chimney.

For this purpose, basalt fiber is used, which is coated with galvanization.

According to numerous reviews, the widespread use of Master Flash roof seals is due to the convenience and speed of installation. Important advantageous factors are the affordable price, reliability of insulation, and long service life.

And there is no point in attracting highly qualified specialists or additional workers, since the instructions for the seals clearly and clearly describe the installation process, which any layman can handle.

Watch the video in which the master explains how to properly install and secure Master Flash for a chimney:

Why is it needed?

Master flush is a universal type of sealant for effectively insulating roof penetrations. The device can be used for all types and coverings of roofs. Well suited for roofs made of metal tiles, corrugated sheets and tin. Installation of the penetration can be carried out both on a roof with a metal deck, and on a soft roof, sand-cement or slate.

An important advantage of the device is its resistance to temperature changes and exposure to sunlight. Therefore, installation of the penetration can be carried out at any time of the year and at any temperature.

Flexibility. With the help of a sealant it is easy to create a tight fit to the chimney;
Heat and frost resistance;
Not susceptible to oxidation;
High strength of the material;
High level of sealing against water ingress;
Resistance to deformation;
Long warranty period up to 30 years;
Easy to install;
Savings on additional waterproofing work around the device.

What is a flash master

The problem of leaks can be radically solved with the help of a special elastic penetration - flash master. This device looks like a round or square base, in the center of which there is a set of rings installed one after another, in such a sequence that each subsequent one is smaller in diameter than the previous one, so that together they form a cone.

The material for the base can be either silicone or special rubber. The advantage of the first is the ability to withstand elevated temperatures, up to 350 degrees, while rubber melts already at 180.

But silicone is destroyed and deformed under the influence of ordinary ultraviolet rays from the sun.

The design of the flash master also includes aluminum elements, which impart rigidity to its base and evenly distribute the load on the system.

Such a flash system must have the following set of characteristics:

Easy installation, allowing you to install such a structure yourself without inviting a specialist.
Acceptable price.
Durable and able to withstand both very low and very high temperatures. It also produces flexible materials that are resistant to corrosion and other impacts. Silicone models can work in conditions of 300 degree heat.
Tightness ensured by the tight coverage of the pipe by the upper ring of the cone.
The flexibility of the design allows it to be mounted on any roofing materials, including tiles, metal tiles, corrugated sheets, slate and on any roof structures - straight or sharply pitched.

All flash seals are divided into two types:

Straight, which is a cone with rings placed relative to the base at an angle of 90 degrees and intended for installation on surfaces parallel to the ground.
Angular, used to seal roofs with slopes, using a cone made of rings protruding at an angle of 30 or 45 degrees.

The flash master is designed to be installed on the roofing, so that its rings tightly compress the pipe section, so that the opening between the roof and the pipe is hermetically sealed from precipitation.

This design can be installed both during the installation of pipes and after their installation, for which some products even have special cuts.

Equipment

The sealing product consists of the following elements:

A flexible cuff, which is a truncated rubber cone. The cone is usually made of silicone or ethylene propylene materials. The cuff serves to connect the pipe to the roof deck. In the upper area, the cone fits tightly to the chimney pipe, and in the lower area it is connected to the base of the sealing structure;
The flange serves as the base of the structure and is made of the same materials as the cone. Can also be made of galvanized steel or aluminum. The base of the flanges has special aluminum strips for mounting on the deck. This gives the structure the tightest possible fastening.

For a pitched roof, special penetrations with cuffs located at a certain angle to the flanges are purchased. On the cone of such a device, corrugations with gradations in diameter are clearly visible. Such corrugations help change the slope of the penetration in the required direction.

Select product.

It is possible to purchase protective, silicone, plastic and rubber roofing protection “Master Flash” for a sloping, pitched roof without any problems. Select the required product based on quality and price. A silicone product has the highest qualities of strength, flexibility and durability, but at the same time, this design is more expensive than similar protection made of rubber and plastic. Rubber and plastic products have a more affordable price, but at the same time they have a significantly shorter service life.

What harm can foam plastic cause when used for exterior decoration?

The use of polystyrene foam is considered absolutely safe for humans, since even the small amount of harmful substances that can be released from this material completely dissolves in the air upon contact with warm air or moisture.

However, in this case, a very important point is the correct installation of the material. After attaching the foam plastic, it must be plastered or covered with other finishing material in order to protect the material from ultraviolet rays and heating in the summer, as this can provoke an increase in the amount of harmful substances released into the air.

Necessary materials

— Master flush for a pipe of the appropriate diameter. When choosing, also focus on the temperature of the exhaust gases, since the choice of material from which the roof is made depends on it.

Advice! When choosing a penetration, keep in mind that a flash master with a reinforced base has a longer service life, but provides insufficient adhesion when installed on metal tiles, corrugated sheets or other embossed roofing materials.

— A plate used to protect the wing from sunlight. It can be purchased at building materials stores or made with your own hands. It looks like an ordinary plate without a bottom.

— Screwdriver, self-tapping screws, metal scissors and heat-resistant silicone sealant
