How to make a pipe bypass on the roof. How to mount the junction of the roof

Often there are abutments of the coating to the architectural elements and building structures protruding on the roof. Different coatings and a variety of architectural solutions suggest a wealth of options for various adjacencies. However, they are all grouped by type of coating and adjacent structures. Often there is an adjoining of the roof to the wall, for example, at the extension of a house or a porch. A complex in execution and occurring almost everywhere are adjoining the roof to chimneys and pipes.

Adjacent to a vertical wall

Where the roof joins the wall, there is a so-called contiguity of the roof to the vertical wall. Typical solutions for metallic and tiled coatings have been developed for sealing this compound. Each reputable manufacturer of roofing materials offers materials and additional elements for typical junction assemblies. There are top and side junction to the wall of the roof.

Metal tile or professional flooring

The standard abutting device is made in a 25x25 mm fine, made in a brick wall at a height of 150 mm from the surface of the roof covering, and a profiled strip of galvanized metal with coating is inserted into it.

This may be the PS-1 interface.

The junction of metal roofing.

In the dowels, the wooden lath is fastened, to which the profiled strip is attached to the screws. Fill fine cement mortar or roofing sealant. The other edge of the strip lies on the profiled roofing.

If the roof is made with a waterproofing layer under the metal profile, then this layer is bent and glued with bitumen sealant on the wall under the bar. In this case, the fastening of the plank to the wall can be done not in a fine, but through a vertical shelf, securing it with self-tapping screws.

Similarly, the roof is connected to the log walls, in which the logs are not cut, but cut logs to a flat surface.

You can not make a penalty in the walls of prefabricated houses, since the panels are load-bearing structures, and the shtraba can weaken them.

Soft tile roofing

Slats for junction should be pre-treated from the inside with bitumen mastic, which will increase the level of waterproofing.

To begin with, the chimney is insulated from the roof structures with asbestos, the crate around is made solid, but with a fire-proof indentation of 130 mm from the masonry. On it establish the lower apron consisting of five elements: two lateral, top and lower levels and a tie. The slats are cut to the desired length and connected to the fold, the upper flanging is turned into a fine depth of 20 mm and sealed.

The apron is glued to the crate on the roofing sealant, and a tie for diversion of water is sent to the nearest valley or to the eaves.

Above arrange a roof covering, which is then set the upper contour of the chimney. Prepare themselves or get ready-made slats, connect them into a single design for recumbent folds. In this case, the upper flanging do not forget to have a fine. The shred is treated with a heat-resistant sealant, for example, based on silicone.

Thus, the water flowing along the coating above the pipe enters the lower, inner apron and is drained by tie into the valley or directly to the ledge. The remaining streams fall on the upper edge of the chimney and flow to the eaves.

The device of two aprons cannot be made on a soft roof, therefore the junction of the roof is carried out according to the scheme of external contour and in fines. To avoid dripping under the apron on top of the pipe, the upper bar is made longer by 300-400 mm. This bar is brought under a soft coating and sealed from both planes. The bar should be with a release of 150-200 mm on each side of the pipe. The remaining strips put on the floor. The device such an apron and do on.

The round chimney pipe is also performed using an apron. Inclined metal plate with a hole and a pipe of large diameter, put on the chimney - these are the main elements of the junction of the roof to the pipe. More reliably than others, an option with a sheet and tube that are pre-fitted and fixed between each other, forming an apron. The shtrab is not made, but the pipe connection is sealed with asbestos at the bottom, and sealed with cement mortar on top.

Modern technologies and materials

New materials make it possible to simplify the device for mating pipes with a sloping roof, reduce labor costs and improve the reliability of the adjoining roof. The finished elastic corrugated cuff made of heat-resistant material with silicone has working temperatures from -50 ° C to + 350 ° C and withstands Russian snow loads. It has a glue base, it is mounted quickly and reliably seals the junction. The service life of such cuffs is about 15 years.

In the absence of such a cuff, the device for interfacing the roof with a pipe is performed using the self-adhesive corrugated metal strips already described (Wacaflex). The strip in its upper part is fixed on the pipe with a metal clamp.

Modern materials allow the device to adjoin various roofs and to other structures not described above: dormer and dormer windows, gables and ventilation pipes of various sections.

The construction of a residential house is quite a difficult process, which is not only associated with various material costs, but also has its own specific nuances. The chimney system is one of the most difficult elements in construction, because the mistakes made during its construction can be fatal for residents.

There is no doubt that the dangerous moment in the construction of the building is the combination of the roof and the chimney. Improper bonding can cause a heated brick in contact with dry parts of the roof to cause a fire.

Chimney exit through the roof

In the process of building a new house or renovating an old building, a logical question arises before the building owner: how to remove the chimney from the building.

There are several options. The first is to lead the pipe through the roof of the house. The second is to draw a pipe separately from the building, near one of the walls of the house.

Consider the negative and positive aspects of each option. Removing the chimney directly through the ceiling and roof will create more problems for the homeowner:

Additional material costs.
Longer term construction facilities.
Complicated cleaning process.

The positive side is that the chimney will give off heat to the walls through which it will pass. Thus, providing additional heating of the room, which levels all the above points, because the owner of the house will save on heating the room.

The second option is when the pipe is attached directly to one of the walls of the house. The advantages of this method is that the funds spent on construction will be much less, while the chimney erection speeds up. However, the heat will not be used efficiently, which will increase the cost of heating the floor space.

Any building is governed by various regulations, there are different standards for the construction of the chimney.

SNiP 41-03-01-2003 provides a complete list of standards that should guide a person when building a chimney.

The location of the chimney on the roof

Most experienced builders agree that the most appropriate place where the pipe should go out of the roof is the area near the ridge. This arrangement was not chosen at all meaningless, because it would reduce the amount of accumulated snow near it, which prevents leakage inside the house.

Also, the height of the chimney in the open air is mineralized, which will protect it from the negative impact of various natural phenomena.

You need to know that there are places where it is forbidden to place the pipe:

near the roof windows, if they are on the roof, of course, this rule is based on protecting the residents of the attic floor from carbon monoxide;
it is not allowed to build a chimney at the junction between the ridges of the roof, because it is impossible to guarantee and ensure reliable protection against moisture.

In addition to the above, it is prohibited to make a rigid connection between the roof and the laying of the pipe itself. When heated, the brick expands slightly, which for several years will lead to the formation of a gap between the roof and the pipe.

Design

The design causes the materials directly from which the chimney will be constructed. Most often, ceramic brick is used, because it is this type of brick that easily tolerates various temperature drops and is not subject to such destruction as other types of similar material.

Modular chimneys consisting of blocks are beginning to enjoy great popularity. The choice of this material on the market is huge, therefore, in accordance with the needs, you can find blocks of various sizes.

Of course, you can not forget about the iron channels. Reviews about them are extremely positive, but a significant disadvantage is their cost.

In accordance with the standards described in the SNiP, the chimney well should be smooth without protrusions or protruding bricks from the common masonry. Masonry joints between bricks must be completely filled with mortar. Similar requirements apply to block and iron chimneys.

The mortar that needs to connect bricks should be made of clay, the negative side of such a joint material is that it is not suitable for buildings exceeding a height of 3 meters.

It is also necessary to make a solid foundation, due to the fact that the construction of brick will have considerable weight.

Tight connection to the pipe

The rigid connection of the roof to the chimney can have various negative consequences. The most common are the likelihood of disruption of the ventilation process in the space under the roof of the house.

In order to neutralize a possible danger, in case it is rigidly attached to the roof, it is necessary to install aerosol grilles and other similar devices.

If an iron structure was installed, then around it you need to build a box filled with a material that does not ignite. Such materials can be basalt, mineral wool and other similar materials.

Other chimney options

Brick is not the only material from which such structures are made. Recently, such a type of material as ceramic modular blocks has become popular.

Lined with such blocks chamotte or porcelain, and between the block and the finishing material is placed basalt, which serves as insulation. The negative side of such innovation is that there are no enterprises manufacturing such modules in our state, all products come from abroad, which significantly increases the cost.

The pipes made of iron are beginning to be especially popular lately.

Of course, for such purposes, ordinary metal does not fit; they make such pipes directly from high-strength material, resistant to high temperatures. Wall thickness should be greater than 0.5 mm.

Iron chimneys can be divided, there are single-circuit and double-circuit. The first ones consist of stainless steel and represent a budget option, as a rule, such pipes are short-lived due to their cost.

More interesting are double pipes, because they consist of several layers, and can be compared with a sandwich. Inside there is a pipe that can withstand high temperatures, it is wrapped in a stainless steel pipe, between them there is a seal that absorbs the temperature.

Such a complex structure protects it from destruction due to high temperatures, but still effectively prevents the formation of condensation hazardous to iron and brick pipes. Of course, option number 2 is significantly more expensive in the market, but it will pay off in full during the operation, which will be several times higher than that of option No. 1.

Coaxial chimneys are a novelty in the domestic market. It works exclusively with a fan. It is installed on boilers running on forced bracing.

Pipe sealing

Sealing one of the most important elements in construction. Any builder, novice or professional knows that water is the enemy of any building. To properly make the seal, you must first glue a special membrane between the roof and the pipe itself. Then make a pipe primer using mastic. The ends of the membrane should be turned up and then covered with a primer and glued.

This must be done in order to completely deprive moisture of the possibility to penetrate into the space between the roof and the protective membrane. After that, the so-called "ties" should be made, that is, the angular metal should be laid in such a way as to ensure that the roof flows free of water.

After that we fill with sealants the places where the plane comes into contact with the membrane. Bitumen mastic very carefully we coat the joints, after which you can install an apron made of plastic.

After all the procedures, it is necessary to raise a couple of buckets of water on the roof and carry out tests to ensure the stability of the structure.

This must be done by all means for the reason that it is better to immediately reveal the shortcomings than to invent in winter what to do with the beginning of moisture penetration under the roof.

The removal of chimneys through the roof slopes must be carried out in accordance with strict rules, since the integrity of the roof and leakage protection depend on the reliability of the joints and connections made. In this article, we will describe how to properly organize the junction of the pipe to the roof, where in the roof it is best to place the chimney, how to choose the height of the pipe, etc.

Junction location

In the regulations of SNiP relating to the arrangement of chimneys, there is no clear regulation of the location of the chimney pipe.

Specifically, only the parameters for determining the height of the chimney:

the chimney should rise at least 50 cm above the ridge if the pipe itself is located at a distance of 150 cm from it;
if the chimney is located at a distance of 150-300 cm from the ridge, then its height may be equal to or higher than the ridge level;
if the chimney is located further than 300 cm from the ridge, it is placed in the level with the ridge or not below the line that is drawn from the ridge at an angle of 10 degrees relative to the horizon.

Condensate may fall inside the pipe or on the inside surface of a protective umbrella. The main danger of the moisture formed is that at negative temperatures it forms frost, which negatively affects the burden. In addition, condensate flows down the walls of the chimney, thereby contributing to the development of corrosion processes and reducing the period of operation of the chimney.

It is better to remove the chimney through the roof as close as possible to the ridge. There are two reasons for this:

in this place it is much easier to organize the junction of the pipe to the roof;
due to the small area of \u200b\u200bthe slope above the pipe, the formation of snow pockets, which lead to leaks, is minimized.

How to seal the pipe on the roof

The question of how to organize the junction of the roof to the pipe arises quite often. This is especially true in cases where the roof consists of several layers of different insulators at once - heat, hydro, steam. The greatest protection is necessary to ensure thermal insulation, since when moisture gets on it, the material immediately loses some of its performance.

According to the regulations of SNiP, in addition to protecting the roofing pie from leakage, it is necessary to take care of fire safety. So, in order to minimize the possibility of ignition of the material, it is necessary to remove the roofing cake at a distance of 15 to 25 cm from the chimney.

The best solution is to seal the roof around the pipe in the form of a protective box, given.

It can be created with:

rafter legs on the sides of the chimney pipe;
mounting crossbeams on rafters.

Thus, the chimney pipe is limited to a wooden box. For even greater security, its internal space is filled with heat-resistant material - in most cases, basalt wool. This copes well with moisture, which allows you to lay a layer of waterproofing directly around the chimney. Similarly, erecting brazier with a roof and a pipe.

Adjacent hydro and vapor barrier films to this element are performed by the standard method:

canvases are notched in the form of an envelope;
their edges lead to cross beams or rafters;
fix the material with staples or nails;
waterproofing is additionally pressed with slat counterbags and crates;
vapor barrier is pressed against the base of the frame under the material of the attic.

At the points of contiguity of the roof to the walls of the duct, maximum insulation of the heater against the action of moisture can be ensured by using a special tape or adhesive composition. Often, builders say that the outer side of the chimney does not heat up above 60 degrees, which allows the roofing pie to be brought directly to the chimney. But in this case one should make sure in advance that the concrete chimney is really well protected from high temperatures and its external walls do not heat up. Otherwise, it is fraught with damage to the roofing pie and the occurrence of leaks, so you need to think.

If the chimney width is more than 80 cm in size, then from the side of the ridge it is necessary to make a razuklonku - a small gable roof, which removes snow and water from the chimney (read also: ""). It is made of the same material as the main roof. At the same time, the organization of such an element is vital. With a large width of the chimney, it becomes a great place to hold snow and rainwater, which ultimately leads to leaks. Also, do not forget that the razuklonka has some difficulties in creating hydro, steam and thermal insulation. Therefore, this must be taken care of in advance. A wide chimney inter alia prevents good ventilation of the insulation. Therefore, on the slopes it is necessary to install additional ventilation outlets. When working, it is important to remember that the chimney pipe is plastered before laying the roofing material. Otherwise, the roof can be damaged (read more article: "

Junction on the roof - These are areas in contact with other elements of the building: walls, ventilation and chimneys, mines, parts of the facade, etc. The junction areas are as dangerous as possible in terms of the formation of possible leaks. At their installation it is necessary to follow special rules.

The Importance of Correctly Joining the Roof

One of the main functions of the roof is reliable weather protection. In order for precipitation not to penetrate, it is necessary to ensure its absolute tightness.

On a flat surface, this is fairly easy to achieve, but the places where the roof adjoins the walls and other structural elements can create serious problems. Snow, rainwater, debris accumulate in these areas, as a result, the load on the roof system is significantly increased and the risk of leakage and violation of the roof covering sealing increase.

Proper arrangement of junction is a guarantee of reliable sealing of the roof. This should be taken care of at the design stage.

If the building is brick, then during laying the special visor is arranged. It is made of half brick. The purpose of the visor is to protect the joint of the roof and the wall from rain and snow.

Some choose another way: they leave a small recess when laying. Subsequently, it gets a roof covering.

Regardless of the method chosen, even before the start of installation work, it is necessary to take into account all future junction points and determine the way in which they will be sealed.

Types of connections to the wall

The docking of the roof and the wall is of two types: upper and lateral. When roofing, we are faced with the task of designing and other construction details: ventilation pipes, chimneys, canopies, and sheds. It is in these places that rain and melt water accumulates, and in winter - snow.

Arrangement of adjunctions to the wall

During the installation of the roof all the junction should be carefully sealed. The sealing process is carried out according to different technologies and depends on the specific type of roofing.

In the presence of a roof based on rolled materials, several methods can be used.

Flash

This method consists in applying to the places of junction plastic mastic in combination with a special reinforcing geotextile. When using this technique, you can get absolutely tight, durable and elastic joint, which also does not lose its quality characteristics for a long time.

This method is so simple that the work can be carried out independently, without the help of professionals. Before applying the mastic, it is necessary to carefully prepare the surface.

When using rolled materials they are cleaned from sprinkling. Polyvinyl chloride should be degreased, primer the concrete, and the brickwork should be plastered and dried thoroughly.

All places of future joints should be cleaned from dust and any contamination. If there are large gaps and chips, they need to cover up. Only after careful preparation of the surface can a layer of mastic be applied to it.

From above stack geotextiles, which again cover with mastic. After applying one layer, you must wait at least 3 hours and no more than 24 - before applying the next layer. Having waited for full drying of the processed site, it is possible to impose mastic of the corresponding color from above.

Fastening with self-tapping screws

When using this method, the place of junction of the roof to the wall is arranged as follows: silicone sealant is applied to the section of the rail joint with the wall. Roll roofing should be raised on the wall by about 15-20 cm.

It is necessary to ensure that at the junction there does not appear a hollow, which can later threaten with a tear. To avoid this, a triangular shaped bar should be installed between the wall and the roof surface and a layer of additional thermal insulation should be laid. The resulting roller is the prevention of a possible breakthrough of the material and additionally warms the junction areas.

Roof of corrugated

In the presence of a roof covering on the basis of profiled sheets, the arrangement of abutments to the wall is carried out using special steel strips or aprons.

To install such a structure on a plastered or concrete base in it, it is necessary to make a notch with a depth of 20 to 30 mm. The notch should be parallel to the wall.

The apron is pre-treated with a silicone sealant, after which it is inserted into the strobe and secured from the bottom using self-tapping screws.

You can also use a double apron. The top element should overlap the bottom. There is no need to shred the surface.

The top part is fixed to the base using dowels. Under it you need to install the bottom element. It is latched onto the upper part using lock joints. The lower apron is equipped with clasps: they must be fixed on the roof using self-tapping screws. At the last stage of the work it is necessary to conduct a complete sealing of all parts of the connection.

When carrying out work, one must remember that at the points of abutment of corrugated flooring to the wall there must be a small gap.

Soft roof tiles

The junction of a soft-type roof to a wall begins with a penalty on the wall. It is performed at a height of 200 to 500 mm from the cover. Along the perimeter of the junction, fix a bar with a triangular cross-section pre-impregnated with an antiseptic substance. It is necessary in order to smoothly bend the roofing pie and create a barrier to water leaks.

The junction areas must be cleaned of debris, accumulated dust, then treated with a primer. Soft roofing should be applied to the timber, and then on the sealant or mastic glue a special strip for the device endova. It is a reinforced with a special technology roll material with a width of 1 meter - an end carpet.

The strip begins with a penalty on the wall, its other end is located on the horizontal part of the roof, at a width of at least 200 mm. Glued roll materials are smoothed and pressed using a special rubber roller. It easily presses the material to the surface without damaging it. If there is a large crumb, it should be removed from the gluing site.

At the end, it is necessary to fix the junction using a clamping metal bar (100-120 mm) with flanging, which is included in the penalty during installation. It should be mounted on the dowels to the wall, using rubber washers.

Device adjunctions to chimneys and pipes

Arrangement of junction points to chimneys and chimneys is in many respects similar to the arrangement of junction points to walls. However, this work has some features associated with high temperature pipes, their shape, location on the roof.

If the roofing material is a metal tile or other cellular and profiled material, the junction is performed by the upper and lower metal apron around the chimney. To install it, it is recommended to release a half-brick when laying the pipe. This technique allows you to protect the upper part of the outer apron from direct contact with rain water.

The chimney must be insulated from the roofing structure with a layer of asbestos, the crate around is made solid, but at the same time a 130-mm fireproof distance from the masonry should be maintained. The bottom apron is installed on it.

It consists of 5 parts: the top and bottom slats, two side elements and a tie. It is necessary to cut off the strips of the required length and connect them to the fold, the upper flanging starts up at a depth of 20 mm, and then sealed.

On the crate, the apron is glued to the roofing sealant, and the tie that serves as a drainage pipe is sent to the most closely located valley or is brought to the eaves.

What is good in construction?

A roof covering is mounted on top, and an upper perimeter of a pipe or chimney is installed on it. Planks can be prepared by yourself or buy ready-made. They should be connected to the recumbent seam in a single structure. We must remember the need for institutions top flanging a fine. Strain is processed using heat-resistant sealant - for example, silicone.

As a result of the work done, the water that flows down the roof covering above the pipe location will fall into the inner bottom apron and be drained by tie into the valley or directly to the ledge. Other streams of water will begin to fall on the upper edge of the chimney and from there flow down towards the ledge.

As for the roof on the basis of soft materials, it is impossible to arrange two apron on them. For this reason, the roofing junction is performed on the outside bypass in the penalty.

In order to prevent any possible leakage from the top of the pipe under the apron, the upper bar should be made 300-400 mm longer than the pipe. It is put under a soft coating, and then sealed from two planes. On each side of the chimney plate should have a protrusion from 150 to 200 mm. Other strips are put on the cover. Similar aprons can be arranged on metal folded roofs.

Sites adjoining the roof to the chimney can be arranged with the help of flashing.

The surface is thoroughly cleaned from any dirt, dust and debris, and prepared for further work. Then it should impose a layer of waterproofing mastic and on top of the geotextiles to stretch. Another layer of mastic is superimposed on it.

Layers should dry from 3 to 24 hours. If necessary, you can apply multiple layers of mastic. An indispensable condition for laying the next layer is the complete drying of the previous one. The result is a very strong, ductile and durable joint.

If there is a round tube, sealing can also be performed using an apron. The main elements of the places of contiguity of the roof to the pipes are a metal inclined plate with a hole and a pipe of large diameter mounted on the chimney.

The most reliable is the option in which the sheet and tube forming the apron are pre-fitted and fixed together. In this case, the penalty is not done: the connection of the pipes is compacted under asbestos. From above it is sealed with cement mortar.

Modern materials and technologies

Materials of the new generation greatly simplify the construction of the points of junction of pipes with an inclined roof. They reduce the complexity of the process and increase the reliability of the roof junction.

The finished corrugated elastic cuff, manufactured on the basis of heat-resistant silicone material, retains its technical properties in temperature conditions from minus 50 to plus 350 degrees. It can withstand large snow loads, typical of most Russian regions.

The cuff has a glue base, its installation is not difficult. The result is a reliably sealed abutment. The life of the cuff is about 15 years.

You can do without the cuff: arrange abutting with self-adhesive strips of corrugated metal. Their width is 280–300 mm, and their length is 5 m. They are made of lead foil or aluminum with an applied layer of glue. At the top of the strip are fixed on the pipe with a metal clamp.

With their help, you can carry out the sealing of very complex compounds on the roof. Their service life is approximately 20 years.

Corrugations are made in a wide range of colors. Cracking down, they increase the surface by 60%.

The material can withstand temperatures from minus 50 to plus 100 degrees. The upper edge must be additionally attached to the wall with a special strip, called a Tank strip. In this case, the penalty is not necessary.

With the help of new generation materials, it is possible to arrange adjoining of roofs of different types and to other details: skylights and dormer windows, ventilation pipes of different sections, gables.

Junction repair

If the need arises to repair the junction of the roof to the elements of the roof structure, the simplest way is to carry out it using the flash method.

It uses a special one-component mastic, which consists of bitumen-polyurethane compounds. It can create a reliable and durable waterproofing and is used to work on surfaces of various forms.

Mastic application does not require special training and special knowledge or tools. In addition, the method is very economical compared to the traditional method of repair using rolled material and hot bitumen.

The junction points can be repaired in another way. It is suitable for cases where the roofing material has recently detached from the wall and is in good condition. It should be pressed with a rail and secure with screws. Sections of joints of the rail with the wall should be sealed with polyurethane sealant.

FINDINGS

The junction is the areas of contact of the roof with the other elements of the building.
Proper arrangement of junction provides reliable protection of the building from rain.
On the device adjacencies need to take care already at the design stage.
Connections to the wall are divided into upper and side.
Sealing of the junction to the wall is carried out in different ways depending on the type of roofing.
When installing connections to the chimney, it is necessary to take into account the high temperature of the pipes, their shape and location.
Modern materials and technologies greatly simplify the work on sealing adjunctions.

We suggest you to acquaint you with the video on the design of the junction of the roof to the wall of the building

Qualitatively equipped junction of the pipe to the roof is a guarantee of the absence of leaks in this section of the roof. Proper implementation of all measures for sealing and connecting this part with the rest of the coating will help to meet the requirements for the arrangement of the chimney on the pitched roof, shown by building codes. In addition, it will ensure the durability of the structure, increase reliability and contribute to the efficient operation of the roofing pie.

Junction rules

Construction norms SNiP do not have strict regulation on the location of the chimney, but contain instructions on the height of this element:

The height of the chimney must exceed the height of the ridge by at least 0.5 meters, if it is located at a distance of 150 cm or less from the ridge itself;
When it is 1.5–3 m from the ridge, the chimney pipe can be equal in height to the ridge level, or exceed it;
If the distance from the ridge to the pipe exceeds 300 cm, then its height should be at the same level with the ridge, or not lower than the line drawn from the ridge, at an angle of 10 degrees to the horizon line.

All other features of the implementation, which requires the device adjoining the roof to the pipe remain without regulatory recommendations, and therefore can be performed at its own discretion.

But given the experience of professionals, it is better to install the pipe on the roof closer to the ridge, for such reasons:

This arrangement facilitates the process of high-quality sealing and provides coverage without leak points;
The closer the pipe is to the ridge, the less space is left for the accumulation of snow and water behind it, reducing the risk of leakage.

Attention! Condensation can form both inside and on the surface of the pipe, which leads to the formation of ice in the cold season. It damages the walls of the chimney, significantly worsening cravings and reducing the lifetime.

Round tube

The roof, equipped with a circular chimney - one of the most common options for private construction.

In order to ensure a quality connection to the roof of such a pipe, standard three-layer structures are produced. The central part of such a multilayer system is made of insulating material. The kit is complemented by a steel flat sheet and an apron-cap, into which the chimney is inserted.

Choose a suitable set is depending on the angle of the slope. For the most common angles and standard systems are available. With the help of such constructions, it is quite simple to make an independent qualitative connection.

On the plane of the roof is made tight and rigid fastening plate abutment. On top of the cap, the top is cut, the size of the cut should allow the pipe to go through the hole tightly, with no gaps. Steel clamp with a gasket of heat-resistant elastic material to the pipe pressed against the upper edge of the apron.

Attention! All materials must be clean enough, as well as the roof surface. This will ensure maximum quality sealing work.

The plate is fixed with screws, using rubber or neoprene pads.

If the angle of the slope does not allow the use of a standard type chimney arrangement system, this can be done without the involvement of specialists. To do this, in order to create a sealed apron, it is necessary to glue the perimeter of the pipe with lead or aluminum tape.

It is also possible to use a finished piece of oval-shaped lead, which is easy to shape on the surface of a soft roof or a solid material roof using a rubber hammer or wooden tool.

Such lead self-bonding is a material with high operational properties. It is resistant to temperature fluctuations, corrosion and the effects of ultraviolet radiation.

One of the ways of self-sealing a round pipe on a metal roof is shown in the video:

Square tube

For the arrangement of square and rectangular pipes, it is very rarely possible to select perfectly suitable prefabricated elements offered for sale. Depending on the type of roofing material, the ways of arranging the adjacency of the pipe to the roof are also chosen.

Roof passage unit

An important point in the arrangement of the chimney is its high-quality connection with other elements of the roof, namely crate. If this condition is not met, then additional rigidity is provided by installing a special element - a sheet of metal.

When performing work on the arrangement often requires a partial dismantling of the sheathing of the roof. At the same time, in order to ensure the rigidity of the structure, a frame made of a wooden bar is mounted around the pipe, to which the layers of waterproofing and vapor barrier are attached. Waterproofing is attached to the crate and counter lattice. Vapor barrier is placed between the roof frame and interior finishing materials. The space between the frame and the pipe must be filled, according to the norms of SNiP, with non-combustible thermal insulation material - stone wool.

Important! Particular attention should be paid to the quality of sealing the junction of the vertical element with roofing material. In the places of their connection there should be no leaks.

Tiling

On the roof, the covering material of which is ceramic tile, the arrangement of the chimney fits is done using elastic type tapes, which are made of aluminum alloy, with an adhesive layer on one side. Such a tape is attached along the perimeter of the entire seam, while partially adjoining the chimney, partly to the roof, smoothly repeating the bends on the tile. Further, the part that is glued to the chimney is fixed with a metal profile bar using dowels made of heat-resistant material. The place of the junction must be properly sealed.

Arrangement of a joint at the roof of shingles is carried out according to similar technology, but the metal tape is replaced by a end carpet, or a tile of an ordinary type, previously wound up in a chimney.

Metal tile

On a metal-tiled roof, a special sealing apron is most often used, which consists of abutting strips for the upper part and for the lower part.

The lower plank is applied to the pipe walls, and then its upper boundary is noted. In this area on the chimney a strobe is made about 1.5 cm deep. It is cleaned of dust and washed with water. With an overlap of 150 mm is the installation of slats.

Attention! This overlap is necessary to prevent further leakage.

The upper edge of the metal element is inserted into the resulting strobe, and sealed with a heat-resistant silicone-based sealant. From the bottom side there is a metal sheet with a corrosion-resistant coating, which ensures efficient water flow. It goes down to the eave of the roof.

So that the junction is completely sealed, before installing the inner apron, waterproofing (5 cm high) is drawn onto the pipe. The top edge is fixed with construction tape.

The metal tile is laid on top of the inner apron. After the installation is completed, the top layer is installed - a decorative apron, using the upper jog bars. The upper edges of the elements are attached to the pipe without gates, and the joint space is filled with sealant.

Clearly this process is shown in the video:

By providing high-quality connection of the vertical part - chimney pipes, to the surface of the roof, you can fulfill an important condition for the reliability of the roof. There will be no leakages at the junction points, and the snow that has lingered on the surface cannot damage the waterproofing layer.
