Chimney on the roof: device and repair. How to make the passage of ventilation and chimney through the roof of the roof cutting under the chimney

The roof cutting of the chimney is a prerequisite for its safe operation And the pledge of heat and dryness in the house.

Errors with output chimney Through the roof usually lead to leaks, rotting and destruction of the wooden structures of the roof, and the improper fastening of the pipe itself can cause a fire. Following the technology described in our article, you will be able to deal with this issue and, if necessary, set the roof cutting of the chimney yourself.

The view of the roof cutting directly depends on several factors: the material of the chimney, the type of roofing and the roofing device: its type, angle of inclination, the location of the chimney relative to the skate. The main quality of the roof cutting is the ability to protect the roof from leaks and overheating, they are determined by the choice of materials for the roof cutting.

The roof cut for metal pipes such as a sandwich is a metal cone, rigidly fixed on a metal apron at a certain angle. For slate roofing, the apron must be made of lead, which, due to its plasticity, easily acquires the form of roofing sheets. The corner of the roof cutter is selected depending on the angle of inclination of the roof. The pipe is inserted into the cone and sealed by the sealing cuff.

For round tubes and roofs with a wavy metal coating, along with a metal roof cutting, you can use peaks from polymeric materials on metallic frame. They consist of a metal sheet - steel or aluminum, with a hole larger the diameter of the pipe and silicone or rubber cap. In the cap, you can cut the hole of the desired diameter, and the base sheet is to be taken along the form of roofing. After mounting to the roof, such a cutting ensures the tightness of the passage through the roof.

In recent years, the prefabricated ceramic sandwich chimneys or traditional brick tubes are somewhat different on the roof. For their sealing, metal aprons are used, adjoining planks and heat insulating boxes. Sealing is achieved by sizing elements with special films and use of sealants, while the correct sequence of work described in the following sections is important.

Roof cutting round pipes

For sealing of pipes like "sandwich" from a stainless steel or ceramic round-section pipes, roof penetrations with a metal or polymer cap are used. In addition, to protect wooden structures from overheating at the passage of the pipe through the roof, it is necessary to establish a thermal insulating box of non-combustible material, and the space between the walls of the box and the pipe is filled with a non-flammable heat insulator. The heat insulator uses stone or basalt wool, their melting point is significantly higher than that of the smoke pipe in operational mode.

Pin with roof and cutting the cutting

Purchase or make their pipe from thin-walled metal. Its sizes should provide fireproof distance from the pipe to flammable designs - at least 25 cm in any direction. The nozzle has a type of box with a lid, with holes on both sides equal to the diameter of the pipe. The pipe must be separated by a non-aggravated insulation - the figure shows the finish of a basalt wool with a heat transfer layer. It is possible to secure it with a heat-resistant sealant and metallized tape.

The place of passage of the pipe through the overlaps is noted and the hole is cut into it in the size of the nozzle with the help of an electric bike to the entire thickness of the heat insulating "cake". Install the nozzle.

Displays the chimney from the Sandwich type pipes through the hole in the nozzle, the gaps are treated with heat-resistant sealant with a working temperature up to 1000 degrees. The insulation is labeled between the walls of the box and the pipe - basalt wool. On the bottom and on top of the passage are covered with covers and fix them on the self-tapping screw.

The passage of the pipe through the roof is noted and cut it in the same way. In this case, the hole will not have a square, but a rectangular shape due to the linker. Install the lower cutting apron. It is chosen depending on the roof slope - the steeper of the skate, the more elongated the hole.

Continue the installation of the pipe through the bought hole, the apron can be temporarily lowered down. The pipe is necessarily tightened by the clamps and fix it to the elements of the roof design to the brackets.

Displays a pipe to the roof to the necessary height. At the same time, it is important to comply with the rule: the connection of the elements should not be located at the point of passage through the roof or overlap, if the pipe dimensions do not allow it to perform it, the trimming of one or more elements is necessary. Clamps, fastening pipe, it is better to install in places of compounds, and the joints to plant the sealant - this is achieved by the maximum stability of the pipe and fire safety.

After the pipe is installed and removed, the bottom apron is fixed, and the roof cutting of the selected type is put on the pipe. Figure shows roof cutting With a metal apron, laid on top of roofing - professional flooring. The top edge of the apron is started under the overlying sheet of the professional flooring, and its side parts are closed so that they are in the upper part of the metal sheet wave. Water with such a design and a large bias of the roof will not fall under apron.

For other types of roofs, the roof cuts of a different type can be used, for example, metal-polymer or with lead apron.

Different types of roof cuts for round pipes

When using a flexible cutter from silicone or rubber in the cap, the hole is cut on 1/5 less than its diameter. The cap is tensioned onto the pipe and give flexible apron the form of the sheet. Fasten on the self-tapping screw, pre-missing the sealant. For a more durable attachment, it is sometimes necessary to strengthen the roof lamp - this is done at the stage of drinking holes in it.

A flexible pilster apron can also be reached in the form of a roofing sheet, but when it should be purchased, the angle of inclination should be taken into account. The top edge of the apron is necessarily started under the overlying slate sheet or metal.

Roof cutting of rectangular pipes

For the roof cutting of pipes from brick or blocks, special elements are used - metal aprons, ties, wall profiles. For sealing joints also use self-adhesive film and sealant.

A pipe of brick or blocks, as a rule, is placed on the foundation, so it is quite stable. Its additional fastening is possible with the help of special brackets, but they should not provide a tough connection with the roof, otherwise, if damaged, the roof is possible deformation and the destruction of the pipe, which threatens the fire.

Brick pipe roof cutting technology

The cutting is performed after the installation of the crate and waterproofing, on top of the counterclaim made from the puzzle board. Planks of the pipe are applied to the walls of the pipe and stick the outline along the top protruding edge.

Contour markup under the plank of adjoining

According to the resulting circuit with the help of a grinder and diamond disk, the grooves.

Sources dust broom and wash off its jet of water, can be made of plastic bottle.

It is applied to the strip of the adjoining from the lower edge of the pipe, mark its dimensions with the marker and with the help of scissors for metal cut the vertical part of the adjoining planka on both sides. Apply the strip of adjustment to the pipe and the hammer gently clog its edge into the groove in the brickwork.

The plank itself is fixed to the crate of self-draws with the help of a screwdriver.

Located in a similar way lateral strips, a protruding vertical part is cut. Both side planks are fixed with self-draws so that they are on top of the bottom. Fasten the upper plank of the adjoining in the same way.

Seal all the joints between the straps and the pipe.

They set the tie and bend on it the chute in such a way that the moisture falling on it to it stamped from the roof, without falling on the crate.

Placing roofing special technology. Install the aprons in the same sequence as the planks of the adjoining: the lower apron, the side, and then the upper apron - it is put it so that it is under the overlying sheet of roofing. If the pipe is close to the skate, then the upper apron is started under it.

Organization Heating cottages and private houses occupies a considerable part of the construction of the entire construction. The erection of the chimney or the installation of the pipe on the roof is the final stage of this type of work. It is from the quality of its fulfillment that the quality and reliability of the obtained home heating system depends largely.

In this article we will tell you how to make a pipe on the roof and protect it from precipitation.

Pipe placement options


The most unsuccessful place for the passage of the chimney are the places of joints of two rocks - endanda. It is almost unrealistic to achieve high-quality in such a place, while the aqueous flow that flows from the roof rods will create an additional load on the chimney pipe. In addition, snow here will accumulate snow here. As a result, the roof can give to flow.

As well as in the case of passing through the horse, this method requires the organization of a more complex rafter system in the fields of endands.

Pipe laying on the roof

It is quite difficult to organize the correct adjoining of the chimney on the roof on the roof, as the roofing pie is solid and it ultimately should remain continuous throughout the area (read: ""). Snip requirements sufficiently describe the conditions for the placement of combustible materials around the chimneys. And the material from which is done by pair-and waterproofing of modern roofs is just treated with such materials. Therefore, depending on the chimney type selected, the insulation films should be from the pipe at a distance of at least 13-25 cm. Good option It is considered.


But how does the pipe on the roof of the house take place in this case? Optimal decision It is the separation of a part of roofing pie from its main plane.

For this can be applied:

  • stropile legs on the sides of the pipe;
  • cross beams installed on top and bottom and having a thickness of the rafted.

That is, in simple - it is necessary to create a peculiar box of wood that reliably separates hot tube From the pie of the roof. At the same time, it is necessary to adhere to SNiP requirements, as the wooden elements should also be placed from the chimney at a certain distance. The box for the pipe on the roof from the inside is filled with the insulating material of the non-combustible type. To do this, basalt wool can be used.

The adjoining of the hydro and vaporizole layer to the installed box is performed by the standard method:

  • the insulation canvas are caught with an "envelope";
  • the edges of the material are adjusted to transverse beams or rafters, where it is fixed with nails or brackets;
  • waterproofing film clamps and counter tests. Film of vapor insulation fixed the base for laying finishing material attic;
  • in order for the insulation that the insulation is reliably protected from moisture ingress, in places of insulation film insulation to the walls of the box, it is necessary to arrange a hermetic seal from the adhesive composition or special adhesive tape. See also: "".

Brick pipe on the roof - junction sealing

Depending on the form of section of the chimney pipe and from the type of roofing material, the correct shape of the passing unit is selected, which can ensure the maximum protected of this roof section (more: ""). But, regardless of the choice, the principle of organization of this node remains unchanged.


One of the most important tasks in the arrangement of the roof and passage through it the chimney is to seal joints. Thanks to the correct implementation of this type of work, you can provide a high-quality removal of water from the chimney. In order to implement this requirement, an apron for the roof pipe is used.

Consider how to make the roofing pipe correctly:


Similarly, the joints of the roof and flexible tile. But in this case, instead of an elastic adhesive tape, an electrical carpet is used or a tile chimney wall. If the roof is created from the metal tile, then the apron for sealing is made from metal sheets having a roofing color (read as well: ").

Organizing apron must always remember that its upper part is necessarily started under roofing material. This is necessary so that water flows first on the roof slide, and then hit the apron. If you put the apron without adhesion under the roof, then such a roof will soon give a flow.

Homut

Clamp Obsol - Designed for fastening elements of chimney, is used to improve sealing at the joints. It is a mandatory element of the system.

Opportunate tells us that it has a different shelf size, so the larger shelf is placed on a smaller part of the pipe -pad, and a smaller shelf on mom. It is important not to confuse, since otherwise the clamp will not fulfill its functions. Check where the smaller, and where the big shelf can be done with a pen or pencil, keep the pencil horizontally, hanging on it the clamp, in which side the clamp is tilted there and a smaller shelf. On a single chimney, assembled by condensate, mounted with a smaller shelf up, greater down. On sandwiches, on the contrary, the larger shelf up, smaller down.

The clamps are elastic and resistant to transverse beggars, so you can easily install them on the already mounted chimney.

Roof cutting

The roof cutting of the chimney is a prerequisite for its safe operation and a pledge of heat and dryness in the house. Errors In the removal of the chimney through the roof usually lead to leaks, rotting and destruction of the wooden structures of the roof, and the incorrect fastening of the pipe itself can cause a fire.

Sandwich shifts through the hole in the roof pipe nozzle, the gaps are treated with heat-resistant sealant with a working temperature up to 1000 degrees.

It is important to know, the top edge of the apron of the roof cutting is necessarily started under the overriding sheet of slate or metal.

When using a flexible cutter from silicone or rubber in the cap, the hole is cut on 1/5 less than its diameter. The cap of the roof cutting is stretched onto the pipe and give flexible apron the form of the sheet. Fasten on the self-tapping screw, pre-missing the sealant. For a more durable attachment, it is sometimes necessary to strengthen the roof lamp - this is done at the stage of drinking holes in it.

For a soft roof, for example, bituminous tiles, two types of adjoining are used - closed and open. Basically, the first option is used quite rare, as it is complicated during installation and is not entirely practical in use, so we will talk about the second method. In this case, the chims are adjacent to the roof of the same principle as the metal tile, i.e., with the help of the apron of the roof cutting and different sealants. Only here is the roof chimney apron for the soft roof of the chimney make not made of metal material, but from an end carpet, which is placed under bituminous tile.

The essence of laying a soft apron of the roof cutting is that the tile with it completely merged, and in the places of the joints of the roofing materials there was no regimen. And besides this, the water should not descend on the attic on the fireplace tube / oven, therefore, on the roof cutting from the carpet you need to make a science.

For fixing uses a variety of bituminous masticsAlthough not all of them are good - after a while the material is peeling, and then the water will penetrate through the cracks. Based on the practice, it can be noted that with this task perfectly copes the same C-36 glue, which can last long enough, without fear of temperature differences, moisture and ultraviolet radiation.

To pass the chimney through any designs, you can use the ready-made ceiling and passing device. Ceiling-bodied fault is used for passing through the ceiling, so for passing through the walls. It is chosen on the basis of the outer diameter of the pipe. Before installing, this is a device for passing through the ceiling, it is necessary to prepare: all surfaces that will contact the wood covering the ceiling, and all the inner surface of the passage box is laid out with thermal insulation, or use the prepared solutions of the PPU with minister, in which the role of thermal insulation takes over the minerite.

Usually, the heat insulation is basalt wool, but it must be special: to withstand high temperatures. Buying material, make sure that it is designed for use at temperatures of 800-1000 o C. These materials have a higher cost, but to save on security is unreasonable. Cheaper options are in their composition binders that high temperatures They sin, because of what thermal insulation loses all its properties, and this can lead to a fire. In addition, it is desirable to use a foil thermal insulator - it will make the design even more secure. It must be remembered that the distance from the chimney to the wall from the combustible material should be at least 500mm, to the wall of non-combustible material 380mm.

Aftercing the passage device, prepare a place to install it. On the ceiling are placed where the smoke pipe will be located. Outlining the hole suitable size: a little less than the sizes of the front panel of the passing device with such a calculation so that it is convenient to be attached to the ceiling over the ceiling by self-drawing. Cutting the hole, its edges, look at the same heat insulator as the passage of the node, or any other with similar properties. To increase the level of fire safety, it is possible to strengthen the metal stripes on top of the heat insulator. Insert the prepared passage device in the finished hole. It can be put on the pipe and install with it. By setting this design to the place, secure the pumping panel by self-draws (the holes can be drilled pre-). For greater fire safety, fill the PPU with thermal insulation, approximately half.

Chimney height relative to the roof

If the pipe comes out of the roof at a distance of less than half a meter from the skate, then the minimum height of the chimney above its level should be 50 cm. In such a place, less is going to snow in winter, which reduces the risk of leaks when it melting in the spring and with thaws. The calculation of the height of the chimney relative to the skate is based on the requirements of SNIP41-01-2003 and the joint venture (construction rules) 7.13130.2013, as well as on the recommendations of the manufacturer of the heating device.

If the roof has flat designThe height of the chimney above the roof is at least 50 cm. On scanty roofs in the case of a chimney location at a distance from the skate to 1.5 m, it should be at least 50 cm relative to the last or enclosing parapet. If the chimney is located within 1.5-3 meters from the skate, then its height cannot be below it or parapet. When the chimney is further 3 meters from the line of the skate, its minimum height is determined by carrying out a line at an angle of 10 degrees relative to the horizon.

The chimney on the roof is a potential source of flammable elements of roofing structures, so when adjusting the smoke pipe node through the roof, special attention is paid to ensuring fire safety. In addition, it is important to ensure the tightness of the adjoins.

The basis of security is the right choice of materials.

Mounting chimney through the roof can be performed by various technologies Using ready-made designs or special elements. The choice of technology is first dictated:

  • the type of roof (flat or scope);
  • features of roofing;
  • form of chimney;
  • the presence and type of chimney pipe facing.

Such structural elements and materials like a trailer, chimney cover, insulation, sealant, strip adjustment, etc. Must match the type of chimney.

The correctly mounted node of the passage through the roof should be fireproof and sealed. Moisture that fell inside roofing cake provokes rotting wooden structural structures, the development of harmful fungal mold, reduces heat insulating properties cotton insulation.

Elements of the passage device, details for sealing and consumables suitable for chimneys of the same type, cannot be used to install different type chimneys.

When buying components and materials for mounting the chimney pipe on the roof, you must familiarize yourself with the certificates of quality for each type of product purchased. It is recommended to contact specialized stores.

Chimney Passage Node through Flat Blood

When installing the chimney on flat roofIt is important to remember that its height above the roof surface should be 500 mm in accordance with the standards. Through concrete slab The overlap can be outputting a round tube, a rectangular chimney box or directly brick chimney. A round tube passage node will be considered separately, and for other cases two main principles of installation are used.

To display the rectangular chimney box on the roof, it is necessary at the installation site to perform the corresponding hole. Pre-at the selected area is removed roofing pie - the finish soft coat and underlying layers. The rolled coating should be 150 mm around the perimeter to enter the prepared cell. The coating is cut and rejuvenated - subsequently, these free edges will be attached to the vertical walls of the penetration. In concrete, a rectangular opening of the required size is performed. The formwork is installed on its edge and the vertical rectangular side of a 150 mm height over the roofing carpet is poured around the perimeter.

After the concrete gains strength, the formwork is removed, and the barefoot is attached to the outside roller coating. To prevent the separation of roofing material from the walls of the side, along its edge with a dowel mounted metal strip. After installing the chimney box, it is important to hydroize the box of the box with a concrete side. To do this, on the adjuncing of the end, the side with the walls of the smoke tube is mounted with a drop with a dropper, made of roofing tin.

Brick chimney on the roof is easier to mount. In this case, the fill of the special side is not required: the brick design passes through the prepared hole in concrete overlap, and weapons with soft roofs are mounted directly to it, after which the apron is installed on top, made of galvanized.

At the required height along the perimeter of the chimney, a horizontal shtrobe depth 15 mm is performed. It should be performed in the brick, and not in the installation seam. The top edge of the metal apron, bent inside, starts in the stroke. Then the stroke must be filled with a building sealant.

Features of the arrangement of the passage through the scope roof

How to fix the chimney on the roof? On the chimney from the inside of the roof, it is necessary to mount the flange, rather hard to perceive the load from the crate - the output of the chimney makes it takes a part of the runs, and without installing the flange, the design will remain in suspended state.

The flange usually serves a steel sheet with rigid ribbed ribs. Sheet thickness should be at least 2-3 mm. The flange should be laid a non-combustible heat insulator - basalt cardboard. This will prevent heat transfer from the chimney to the crate. If the design of the chimney is not reliable enough to take part of the load on the roof, on the perimeter of the opening is mounted stropil design Or additional racks so that the load is transmitted to the attic overlap.

Around the pipe, all the layers of the roof must be carved for a gap corresponding to the standards specified in SNOV (depending on the type of pipe and the degree of its heating). The resulting gap is required to fill in a non-flammable heat insulator - basalt or glass wool, basalt cardboard.

The principle of sealing the adjoining of roofing material to the chimney pipe depends on such factors as:

  • pipe section shape;
  • material manufacturing and chimney coating;
  • the location of the pipe outlet on the roof.

To the chimney derived through scope roof, it was not damaged at the occasion of snow, it is recommended to establish snow designers above the skate. With the width of the chimney (across the skate), over 800 mm, above it on the skate should be mounted a special design, a decoding water flow.

Conclusion through the roof of the pipe with a circular cross section

It is very difficult to perform waterproofing the roof adjustment to the circular cross section without using special roofing penetments. In the construction market, a wide selection of nodes for pipes differing in diameter and manufacturing material are proposed.

A universal option is an aluminum flange equipped with silicone or rubber corrugation. Multiple sizes of these elements are available, so that you can pick up a penetration for a chimney pipe of any popular diameter. The working surface of the flange is covered with a material similar to the material of the corrugation, and is equipped with grooves for filling with a sealant. The top of the corrugation cone is cut under the required dimer, after which the penetration is required to pull onto the smoke tube. The flange must be wrapped with a sealant and attach to the roof by self-drawing, which are included. If the roofing coating is not made of metal, the flange is attached to a dowel or long self-drawing directly to the crate.

For roofs with a different slope slope, there are penetrations in which the corrugation is located at different angles to the flange. You can purchase a detachable design that is used if there is no possibility to pull the corrugation on the pipe due to the presence of protruding parts or a large height of the mounted chimney. Such a penetration is equipped with clamps, thanks to which the corrugation is tightly crimped around the pipe.

The fastening of the chimney on the roof can be performed using the pebbles in which the hinged segment is used instead of corrugations. This is a universal version for the roof with any inclination angle: the surfaces of the docking elements have a spherical shape and can be fixed relative to each other at any angle.

Manufacturers of materials for the roof often offer finished penetrations for flue pipes with a flange, pre-molded under the appropriate roofing coating. Such a penetration is attached to the roof crate with the necessary overlap. To achieve a coincidence of diameters, cone the apron is cut. People from roofing manufacturers have several standard tilt angles. For the sealing of the joint, the second conical apron of braziness is mounted with the first.

To compensate for temperature extensions, such jokes are performed without fasteners. This allows the tube to "breathe", as well as not to experience additional destructive loads from the roofing structure.

The withdrawal of smaller pipes of rectangular section

The chimney on the roof chimney in this case is rarely performed using the finished penetration - on sale few nodes for pipes with a rectangular cross section. At the same time, special tapes and strips are produced, with which you can perform high-quality waterproofing. Specialists-roofers When installing rectangular chimneys, a two-layer apron of roofing tin is usually made - such a design is well combined with a roofing coating of almost any type.

The apron consists of the front and rear, as well as two side. The main is the inner apron - its lower part is started under the roofing coating, and the upper goes on the walls of the chimney. The side sides of the apron are equipped with sides, a wide metal sheet with side sheets under the shelf of the front part. This sheet (tie) passes under the roofing coating to the drain or endand.

If the pipe of the chimney is made of brick, on the top edge, the apron should perform a marker that enters a specially designed horizontal stroke with a subsequent grinding sealant. In other cases, the edge should put a rubber seal with a sealant. The apron is attached to the pipe and the crate of dowels. The upper apron is performed from the metal under the color of the roof - this is a design made from the corner of the frame. It performs a decorative function and helps reduce the amount of water falling on the bottom apron. Adjusting the upper apron to the pipe is wicked by a sealant.

Principles of adjusting device

Considering the options how to set the chimney through the roof, you should pay attention to the installation of adjustment. To the most simple ways There is a pasting of a pipe passing through the roof, thin sheets of metal. For this purpose, lead or aluminum sheets with a special adhesive layer are used. This option is well suited when installing the chimney on the roof with the roof of the metal tile. The surface of the roof is required to degrease well. The upper edge of the adjoint additionally should be pressed to the pipe with a special metal bar-drip, attaching it with dowels or self-drawing. The joint with the pipe is wicked by a sealant.

For sealing a node of the flue tube passage through the roof from Ondulin, complete planks are used. For surfaces, transverse slope, apron is used for longitudinal - endow. The joints should be punctured ondouflesh ribbon.

Before installing the roof chimney, it is necessary to familiarize yourself with the recommendations of manufacturers of factory chimneys and roofing materials. This will allow you to install technologies and ensure the safety and reliability of the design.

Chimney on the roof: how to install chimney through the roof, the fastening of the chimney


Installing the chimney on the roof. Highlights when making chimney mounting through the roof. Features of the installation of rectangular chimneys and round sections.

How to make a pass through the roof of the chimney: opportunities and options

As a rule, in the installation of internal chimneys, the most serious difficulties arise when it is necessary to arrange a passage of chimney through the roof and overlap. If in the second case, the passage through the overlaps must mainly ensure the fire safety of the building, then the passage through the roof, in addition to fire safety, should be completely sealed from the penetration of moisture.

Chimney through roofing

Major Nude - moisture

If the passage of the chimney through the roof is incorrect, then not to avoid moisture from entering the flocks of chimney, which will lead to wetting of bearing wooden structures, the formation of dampness, harmful fungal splashes and over time is able to completely destroy the carrying roof structure. To avoid this, the yield of the chimney through the floors overlap must be performed correctly and neatly.

What chimney is such a passage

Considering this issue, it is worth considering that there are many ways to organize a pipe out of the roof. It affects its device, first of all, the type of chimney itself, the method of its outdoor decoration.

  • After all, if, for example, the installation of the ceramic chimney and its output to the roof occurs, then this is one option, and if the chimney is a simple brick or from the tube sandwich, it is completely different.
  • Ceramic chimney can also have several options for the outer decoration.
  • If, for example, a part of the chimney, located above the roof, is facing the brick, the installation is carried out in one scheme, and if it is simply plastered, it is already on the other.

After all, if in the first version, directly with the roof, will contact the external concrete blocks chimney, then in the second version of the brick, the installation of which begins with an intermediate crown, located under the bearing struck construction.

Cleaning and roofing material - an important factor

In the way the node of the flue of the chimney through the roof is arranged, the roof coating plays an important role. Most often, you have to work with a coating of a professional flooring, metal tile, ondulin. Often the need to remove chimney on soft roof.

Passing elements: Various features

Depending on the overlap materials, the output of the tube sandwich through the roof of the chimney can be aligned in a different way. On the soft roof the withdrawal of the tube sandwich is carried out like this:

There are passage elements that can be installed in any convenient location.

  • In the roof, a hole is formed through which is output, for example, the pipe of the modular chimney. Imagine that our roof overlapping has no powerful beams for fastening the passage.

  • In this case, we use the precast pass from two parts, which is fixed with the help of self-tapping screws from the inside, as shown in the picture.
  • After that, from the outer part, it is glued with silicone a special rubber seal.

Passage with seal

  • The non-combustible insulation is stacked from above in such a way as to fill the gap between the precast passage and the chimney tube. Wherein insulating material It should not cover the rubber seal.
  • Then the roof cutting is fastened, which comes complete with the precast passage. Fastening is carried out using self-tapping screws.

Roof cutting: types and options

But we are also interested protection against water. If we had a modular steel chimney from the tube sandwich, we would use a special roof cutting.

Currently there are many different species roof cuts According to the method of execution, material and angle of inclination. As a rule, they mainly go with a slope of 15-35 ° or 35-55 °, depending on the angle of inclination of the roof.

Is it possible to apply such a way in our case? You can, but you can use the self-adhesive ribbon for adjustment.

Tiled roof - a special approach

And if we have a roof of a tile and chimney, covered with bricks? The processing of the outer chimney is performed with special diligence. For processing chimney, a corrugated, self-adhesive, leaf aluminum or self-adhesive leaf lead is used.

Our reference: leaf aluminum or lead exists in the form of an insulating roll with self-adhesive one side. The second side is covered with lead or aluminum foil to protect against various mechanical effects and aggressive influence of weather phenomena (snow, rain, hail, etc.).

Roofing from professional flooring

The roof of the professional flooring earned the confidence of consumers, thanks to its reliability and attractive mind. On the roof from the professional flooring metal sandwich tube can be output as follows:

  • on the surface of the professional flooring the place of installation is planned;
  • with the help of the grinder cut the cornet, retreating inside a couple of centimeters. Cutting professional flooring is needed very carefully so that the jar is not formed;
  • by making the holes in the corners of the slots, the professional flooring should be cut up;
  • now cut the overlap, making a similar hole;
  • conduct the installation of a metal box through which the sandwich tube should be displayed;
  • by the output of the sandwich tube on the roof of the corrugated floor, the box is placed in the box or pour clay;
  • on the sandwich, the pipe is put on the silicone seal and glue it to the professional floor, forming a hermetic node of the output of the chimney pipe.

Roofing from Ondulina

To make the passage of chimney through the roof from Ondulina is not easy, but still work can be done with your own hands. The fact is that the coating from Ondulina is flammable. Therefore, in order to organize the withdrawal of the chimney pipe, you need to make a high area with an ondulin coating.

So that the hole in the coating from ONDulin has not become a leakage site, they carry out the installation of passing roofing parts, that is, the output is organized through a metal roof cutting with apron. The angle of inclination of the cutting is selected depending on the steepness of the roofing of the ondulin. When installing the cutting, its ends are administered under the layers of Ondulin

Metal tile: We do according to the rules

Well, if we have a coating of metal tile? Most often, the passage of chimney through the roof from the metal tile is arranged by the traditional, external installation of the cutting. However, this method is not entirely reliable and effective.

Now consider how to properly set the cutting around the chimney, lined with brick on the roof of metal tile.

  • For hermetic adjoining metal tile with chimney pipes, above the roofing rod, we use the so-called inner apron.
  • The inner apron is arranged before laying the metal tile around the chimney.

Inner apron - unequivocally stroke

It can be made both from galvanized steel coated, and without it.

Making an apron with your own hands:

  • The steel profile must be applied to the pipe wall and mark the top edible edge on it.
  • Then, with the help of a sleeper, it is necessary to label the wall of the pipe along the planted line.
  • At the end of the stroke, it is necessary to remove dust and rinse with a stroke with water.
  • Installation of an internal apron begins with its lower element. Steel profile must be trimmed in the right places. The element is installed in place and tightly pressed.
  • Watch out for the exact coincidence of the top of the element with shrice.
  • The mount is carried out using self-tapping screws low part Inner apron, in wooden roof elements.

At the same way, cut and install the side and upper elements of the apron. At the same time, do not forget to make the allen on the adjacent parts of the apron, the size of at least 150 mm, in order to avoid water leaks.

Sealing internal apron

  • A steel profile inserted into the stroke should be sealed with a special sealant.
  • Under the lower element, the apron is started with a flat sheet, the so-called tie, through which the flow of water will go.

We carry out the tie of the tie with your own hands:

  • "Tie" for water flow is sent either to Undov, or down to the roof cornice.
  • On the edge of the tie the side is made. This is performed by simple bending of the edge with pliers and hammer.

After the roofing sheets are installed around the pipe, installation is carried out outdoor apronbut . It is installed similarly to the inner apron, but its upper edge in the stroke is not accumulated, and the joint is sealing with a special sealant.

Materials: the right choice is the basis of security

We looked at several of numerous ways, how the roof cutting of the chimney is satisfied, allowing the pipe through the overlap on the roof.

Now I want to draw your attention to the fact that in no case cannot be done when you need to spend the chimney through the roof.

  • As a rule, the modern roof is a sort of puff pie. Many materials used in this cake are absolutely not intended for the neighborhood with elements subject to heating.
  • Choosing a pecker for chimney, first of all you must take care of the fire safety of the building and only in the second - about his tightness.
  • It should be understood that the chimney on the roof is not just one of the elements of the decor of your building, and the current unit, from proper design and the devices of which may depend on the safety of your property and your life as a whole.
  • Any materials, whether it is a sealant, chimney cover, insulation and more, should fully correspond to the chimney used.
  • After all, the possibility of some elements of the device for passage or sealing one chimney is completely not suitable for use with another.

No guarantee - no material

Purchase materials only in specialized stores in which there are competent sellers consultants who can correctly appreciate the device of your chimney and advise you to purchase a particular material or, on the contrary, protect you from rampant actions.

Our advice: when acquiring elements of chimney, passes, parts and parts of sealing and insulation, require sellers of providing quality certificates for each type of product.

If for any reason you do not charge certificates, give up the acquisition of this product. Do not believe the word about the certificates available, such as certificates are, but the boss is now not, and all documents from him.

Arriving the output of the chimney to the roof, take the materials in those places where there are quality certificates for such products, even if the price is somewhat higher. Such savings can subsequently do to you.

Chimney on the roof: device and repair

Heating country house It is not easy and troublesome business.

One of the important steps that will be able to work with the maximum efficiency of the heating system is the correct installation on the roof of the furnace of the chimney.

Requirements for furnace chimneys

There are several standard parameters that must match the chimney:

The main parameter that affects the force of thrust is the distance from the roof to the edge of the chimney.

Not always the chimney, which comes out of the roof by 2 meters is good.

In the long tube, the exiting gases are hot and their sharp cooling occurs during the passage along the pipe.

And condensate appears on the inner walls of the chimney.

The pipe must have a cross section corresponding to the size of the furnace.

The big sizes have a firebox, the stronger the fire burns in it.

Accordingly, the amount of smoke in it is greater.

In order for smoke to freely outward, the chimney of a large cross section is necessary.

If its size is insufficient, the smoke will begin to penetrate the room.

If the pipe cross section is greater than required, then a decrease in the force of traction will occur.

After all, smoke, climbing such a chimney, will cool, without going out.

Conclusion through the roof

Experts agree that it is best to output right through the horse.

In this case, the adjoining knot to the roofing pipe is easier to arrange.

Also, with this option, snow pockets are not formed, and therefore the probability of leakage will be minimized.

However, there is one, but very big minus: where the chimney will take place, it is necessary to take a break beam, and install additional supports.

Either the design of the rafter system of the roof should not be a skunk carrier beam.

It should also be considered when the chimney device: round-section products are produced by a huge number of enterprises.

But components, with which you can perform a passage of round pipes through the roof, no.

They are simply not released.

It is for this reason that most chimneys have a square and rectangular cross section.

Another good location of the pipes on the roof is its placement on the skate near the skate.

With this placement, the appearance of snow bags is also unlikely.

And from the technical point of sight to arrange such a way out much easier.

The most unsuccessful place to install is rtandov.

I.e internal cornerwhich is formed by the joint of two rocks.

It is almost impossible to achieve a high-quality adjacent roof to chimney in such a place.

Yes, and the flow of water will create an additional load on the pipe.

Relief technology

At what type of roof cutting will be specifically used, there are influence of several factors:

  • the material from which the chimney is made;
  • type of roof and roofing device;
  • roof slope angle;
  • the location of the chimney.

The roof cutting is designed to protect the roof from overheating and leaks.

It is these requirements that determine the choice of material from which the cutting is made.

For metal pipes, the roof cutting is a metal cone, which is rigidly fixed at a certain angle on the metal apron.

If the roof of the house is from an ordinary asbetic slate, then a lead apron is used.

The chimney is inserted into the cone and with the help of the sealing cuffs are sealed.

If the roofing material is metallic, and the pipe is round, then not only the metal cutting can be used.

Now they often use a penetration made of polymer on a metal frame.

There are such penetrations of aluminum and steel sheet and rubber or silicone cap.

The hole is cut out the hole of the desired size, and the sheet is strifted under the roofing coating.

Traditional brick or prefab sandwich chimneys from ceramics are removed on the roof using other fixtures.

The brick tube has an expressive look and does not need additional finish.

Sealing them are performed using a metal apron, the heat insulating box and the adjoining bar.

Tightness reaches the fact that the elements are sampled by special films and use sealants.

Roof cutting. Round chimneys

As mentioned above, it uses penetrations with a polymer cap.

To protect at the place of passage from overheating wooden designs, Install the thermally insulating box made from any non-combustible material.

The space between the pipe and the walls of the box is filled with any non-flammable heat insulator.

How to insulate the roof of the mansardy. As well as a house and garage.

This is usually basalt or stone wool.

Display on the roof and install the cutting

We purchase a nozzle made of fine metal.

The size of the nozzle is at least 25 cm from the pipe to any design that can ignore.

In the ceiling, the hole is cut on the diameter of the nozzle to the entire depth of the Pie.

Then the nozzle is inserted.

The chimney is output through the hole in the nozzle.

Put the insulation between the pipe and the walls of the box.

The passage from below is closed with covers.

In a place where the chimney will pass through the roof, the rectangular hole is cut into which the bottom strap apron is installed.

The pipe is tightened by clamps and with the help of brackets is fixed to the elements of the roof.

The chimney is output to the required height.

In places of compounds, clamps are installed, with which the pipe is attached.

The joints are planted for sealant to achieve maximum stability.

After the chimney has brought out and installed, it is necessary to fix the lower apron.

The roof cutting is put on the pipe.

There are different cutting for each type of roof.

Roof square cut

In order to perform a cutting of square pipes made from bricks, several special elements are used: ties, metal aprons, and wall profiles.

The sealing of the joints is performed using the sealant and self-adhesive film.

The chimney from the brick is not built without the foundation, therefore its stability is much higher than the round metal.

The cutting of such pipes is performed after the lamp is installed and waterproofing.

The flurshes of adjoining is applied to the walls of the chimney and the contour is stuck on the protrusing edge.

For this contour, with the help of a flat-grinding machine with a diamond disk, the grooves grooves.

Plank adjoining is applied to the lower edge of the pipe and the dimensions are noted on it.

Now on both sides, cut the vertical part of the plank with scissors for metal.

Then the bar should be attached to the chimney and score its edge into the groove.

Planck itself is attached to the crate.

Similarly, they come with side and top planks.

All joints between the pipe and the bar are sealed.

The tie is installed so that the water, which will accidentally fall on it, did not fall on the crate.

Now the roofing coating is stacked and the lower, upper and side ties are put on top of the chimney.

If the horse is nearby, then the upper tie is started under the horse.

If the pipe just started to collapse (with brick products, it happens), then there are enough all the seams that have been poured, molded with mortar.

If the brick itself is scattered - it will have to disassemble the chimney and fold on a new one.

Well, if several outer bricks collapsed.

And under the roof everything is in order.

If something happened to the metal pipe, then it is easier to replace it in many cases than to fix it.

Isolation of jigs

For insulation joints use a special sealant.

And here there is one subtlety: if you do not want to rush on the roof at the first rain and all isolate again, do not save on sealing.

He is not expensive.

Buy a german or Finnish brand thing - you will not regret.

Chimney on the roof: device, cutting and repair


The device of the chimney work is not easy. Because you need to consider a large number of Nuances and know subtleties. It is for this reason that it is rare who does it himself.

The cutting is a chimney element that is performed when the chimney is passed through the ceiling or roof. The right cutting is the key to the long functioning of the chimney itself, as well as heat and dryness indoors. At the same time, even professionals can make errors when choosing and installing cutting. To monitor the services of a specialist or independently perform the design, you need to understand some nuances.

The main function of the cutting is the execution of the passage of the pipeline through the fencing. Under the fence is understood as the ceiling or the roof itself. The passage should be sealed.

With a properly executed cut, no drop of external precipitation falls into the room, not to mention the inner space of the room.

Separately there is fireproof. The fact is that smoke gases pipe heats up to significant temperatures. Even after the passage of all heat exchangers, the outgoing gases have significant temperature indicators that, when contacting the pipe with a flammable surface can serve as a source of fire.

Therefore, the space between the elements of the cutting and the pipeline is filled with sealant. In most cases, this is mineral wool based on basalt. In addition, in the internal elements of the cutting include an apron of metal, which protects the surrounding surface from elevated temperatures.

Basic rules and norms

In fact, the standards in the cut is not so much. To be honest, then only one is right, everything else is solely recommendations received by long construction experience. The rule disgraced by SNIP is reading: when performing a chimney from concrete or brick, as well as any other insulated materials, the distance to the rafter beam and any other flammable surface should be at least 13 cm. In any other case: at least 25 cm.

Experienced roofers are advised when performing a passage through the roof on internal surface Roofing cake to perform an apron from the metal of the rectangular shape with indents from the end of the feeding hole of about 30 cm.

Types of passing units through the ceiling

The passage nodes are divided into form, depending on the insulation used, as well as the main constructive material.

By the main material allocate:

  • Steel nodes made of steel thickness from 0.5 mm. The most popular option, since metal nodes combine ease of installation, strength and resistance to mechanical damage.
  • Asbestos. Asbestos cheap and reliable, but fragile material. Any mechanical damage can spoil the purchase.
  • Minrit. New Material in the construction market. Very often, the manufacturer recommends this material for mounting the aprons and protective surfaces, but many buyers remain dissatisfied with the quality of the products therefore it is better to annoy and purchase a familiar steel node.

Depending on the insulation, structures with materials are distinguished:

  • Ceramzit
  • Vermikulitis
  • Basalt mineral wool with foil. It is used more often than others, as it is easier to use, more suitable for self-mount And managed to establish itself in the market of building materials.

Any node always has a rectangular base, but the form of passage will be varied, so there are two types of nodes in the form of the passage of the passage:

  • With double cylinder
  • With double rectangular box

The best choice will be a steel passage knot with insulation from mineral wool. The shape of the passage node is selected based on the form of the pipeline and the personal preferences of the owner.


Factors affecting the cutting of chimney

The form of the chimney is primarily affected by the roof type: flat or scope. The flat roof does not accept techniques characteristic of the scope. As a rule, the cutting on a flat roof is performed from concrete, while the materials for cutting scope roof differ, but most often it is performed from the metal.

The form of the chimney is particularly important, since the shape of the passing hole depends on it. The round shape is better for the chimney itself, but if we talk about the passing holes, then it is much easier to perform a rectangular chimney. For round, you will have to perform the right slot in the roofing pie, for a rectangular chimney it is much easier.

Also, the choice of installation technology has an impact of the presence of facing and a form of roofing coating. Facing makes the cut much more difficult. The fact is that cladding can contribute to the penetration of moisture inside the roofing pie, which is unacceptable. Therefore, it would be logical with the use of cladding to do the cutting wider, but the cut itself also needs to somehow hide. Therefore, the designs under the lining remain a lot of professionals. Too many specific skills need to have to do everything imperceptibly and really beautiful.

If we talk about the type of coverage, then it is better to use professional flooring to perform the cutting. The remaining species are associated with certain difficulties. It is necessary to calculate the coating. Since the apron is supplied to the element of the finish coating of the roof, and some kinds may become on the roof at an angle or shame, which makes the coating of a non-negro.

Installation technology and roofing

Mounting technology cutting round and rectangular pipes are different. The fact is that the form of the passage assembly changes itself, which means that the technology of performing the penetration changes. The shape of the chimney is caused only by the desires of the owner. The fact is that the round tube will not accumulate soot. In addition, the outer part of such a chimney has a more streamlined form, which improves the aerodynamic protection of the pipe. But the rectangular pipeline is easier to hide. It is more profitable from aesthetic point of view, so sometimes apply it.


Round pipes

For round tubes, it will not work independently, so you have to use purchased items. Honored popularity in the market are the flanges on an aluminum basis. A moving silicone or rubber corrugation is attached to a round basis with rivets, which is tensioned with the pipe. From the inner and outer side, the passing elements are connected to each other, resulting in a reliable and strong connection.

For cases when it is impossible to pull the connection to the pipe, there are detachable flanges that, thanks to the special technology, you can wrap around the pipe and pull with a minimum gap between the cutting and the pipe.

Rectangular pipes

Rectangular pipes are popular for various design projects. In addition, the main details of the cutting can be made independently made of sheet metal. It:

  • Wailed profile or inner apron
  • Tie
  • Exterior apron

All these elements are corners with cuts in the scene of the bend. The upper part of the apron bends inward, thus, an element of a used profile is obtained from the corner, which will overlap the adjacent element.

Experienced roofers make aprons from tin, but if desired, you can perform everything from stainless steel.

The tie is called a triangular flat sheet of metal, which protects part of the negotia under the pipeline from soaking.


Features of the cutting of brick pipes

Peculiarities of brick tubes only 2:

  • Brick tube relies on the foundation. It means that it is stable and does not require additional fasteners in the form of brackets. At the same time, the execution of such fasteners with rigid tightening of the clamps can threatening the deformation of the roof tube, which can lead to a fire or building collapse.
  • Brick is a porous material, so it needs a somewhat greater cutting from the cutting. Therefore, the seated profiles are mounted in a special groove, which is performed in a brick tube by shifting with a grinder.

The procedure for performing the cutting of the brick chimney is as follows:

  1. The chimney is performed after the counterbalax. The task of sticking to create a groove for the bottom rack of a used profile.
  2. Mounted bottom wall profile. Fasten it with bolts to a counterclaim. A tie attaches to the bottom rail. The tie is a metal sheet in the form of a triangle with an end slightly bent up. The end of the sheet is bent so that the water does not penetrate the attic room.
  3. A closed profile is wicked by a sealant.
  4. Mounted side and top planks. After that, the wall profile is covered with a coating that is pressed by apron.
  5. The upper apron is removed under the floor sheet or under the horse, if the pipe is next to the skate.

Cutting chimney is a fairly important process. Therefore, all attachments should be performed qualitatively and reliable, otherwise the roof is possible in the chimney area. Compliance with instructions and regulations will allow you to do everything right and durable. Properly mounted chimney will serve not one decade.
