To take or not to take a universal roof sealant. Instructions for mounting a ridge on a metal tile and choosing a suitable sealant Sealant for a metal ridge

Creating a beautiful and practical roof is a responsible process that requires attention to detail. It is not enough to choose a roofing material, you must also purchase a variety of products designed to provide the roof with tightness and good thermal insulation.

If you chose profiled products as the roofing material - corrugated board, euro slate, etc., then you need to purchase roof seals used to protect the under-roof space from the penetration of moisture, dust and insects from the outside. Since the formation of voids during the installation of the mentioned types of roofing is inevitable, it will be necessary to resort to the help of sealants in any case (neglecting this product will lead to premature destruction of the roof).

Sealant for corrugated board and metal tiles

The task of the seal is as simple as possible - it must exactly repeat the relief roofing material and stick to it tightly. Each type of roof has its own sealant (there are also universal models), so there shouldn't be any problems with its choice.

For the production of these products, foamed fiberboard is used - a material with excellent performance: hydrophobicity, flame retardancy, chemical and biological stability, and a long service life (up to 90 years).

The roof structure made of metal tiles and corrugated board has a rather complex device. The structure of the slope can be figuratively represented as a puff cake, consisting of roofing, thermal insulation and waterproofing materials, which together make the roof strong, reliable and durable. Special difficulty the installation of the ridge appears, that is, the lines where the roof slopes converge.

To prevent this element of the roof from causing leaks and increasing heat loss, a heater is needed. Previously, improvised means were used to insulate the ridge connection, which remained from the installation of the roof, that is, it was made from the remnants of the base material.

Now used for sealing versatile material which is sold in any hardware store. In this article we will tell you how to choose a seal for a ridge from metal tiles and corrugated board.

A ridge or ridge connection is a line that forms at the junction of roof slopes. This is an important element of the roof, correct device which plays a huge role in the operation of the roof.

The profile of the metal tile has a wave different shape, corrugated board - trapezoidal. Because of this, it is necessary to install a seal under the ridge. In this case, it is important to observe 2 conditions:

On the one hand, rain, snow, cold air so it needs to be isolated. Since the surface of the coating is uneven, cracks and gaps form in the ridge axis. Without junction strips, the ridge is the most vulnerable element of the roof to leaks.
On the other hand, the ridge connection serves to ventilate the roof. Therefore, the device of the roof ridge must have holes through which it does not allow moisture to penetrate, but air freely passes, which is so necessary for ventilating the under-roof space.

Important! Various roof seals can be used to equip the ridge connection. Both purchased and homemade seals are used. For the manufacture of additional parts, you can use the same material from which the roof is made.

What is a sealant?

According to the experience of professional roofers, most of the leaks occur in the area of the ridge joint. Worst of all, when the roof starts to leak in autumn-winter period when repairing the coating can cost a pretty penny.

When solving the issue of preventing leaks, homeowners often wonder what a sealant is and which one is better to choose for ridge equipment. . The seal at the end is a special material, which is a tape of moisture-resistant porous material, it is placed on both sides of the ridge under the ridge profile.

The ridge seal exactly repeats the shape of the metal tile, so it fits very tightly, not letting moisture through. It must have the following characteristics:

Moisture resistance. The ridge sealant constantly interacts with water during its operation, therefore the material from which it is made must have a high resistance to moisture: it must not wrinkle or deform when wet.
Breathability. Ridge detail serve as an aerator through which it penetrates into the under-roof space Fresh air. Therefore, the porosity of the sealant allows you to seal the gaps between the sheets of material, while not hindering air circulation.
Suitable shape. The ridge seal is selected for a specific tile or corrugated board, depending on the shape of their profile. For all profile materials, a suitable seal is supplied in the kit.

Note! If you choose the right material for waterproofing the ridge, it will protect against the penetration of dirt, dust, melt and rain water, cold air, as well as birds and pests under this element of the roof, the harmful effect of which leads to premature repair of the roof.

Varieties

When choosing a sealant for the ridge of a profiled sheet or metal tile, it is important that it comply with the main principle: it must fit the shape and size of the roofing material, be highly resistant to water and breathable. Only then the process of installation and operation of this element will not cause difficulties.

There are the following types of seals:

Universal. The universal type seal is a tape made of high-quality polyurethane foam. It is laid between the roofing material and ridge profile, taking up any required space. This material acts as a filter, allowing air to pass under the roof, but preventing dirt, insects and water from penetrating there. It often has a self-adhesive backing, so it sticks easily to the surface of the roof slopes. This process characterized short time bonding and simplicity.
profiled. This type is made from a modified, denser polyurethane foam. One edge of the tape is cut according to the shape and dimensions of the metal tile, so it fits perfectly to the roofing. To ensure air circulation, ventilation holes are made in it.
Self-expanding. This type of seal is very popular due to its versatility. Under influence high pressure polyurethane foam is highly compressed, and when released it expands, filling the smallest gaps. It also comes with adhesive tape to simplify the installation process.

Remember! The design of the ridge depends on the type of sealing material. Metal tiles require the use of a universal or self-expanding material, corrugated board - profile, soft roof- not demanding in this matter.

Mounting technology

It is important to understand that regardless of the roofing material used and the roof structure, a sealing tape is used to seal the ridge joint.

However, when working with profiled materials, the gaps due to the shape of the profile are larger, so these places most often cause leaks. It is not recommended to neglect this event, since the repair will cost more than the purchase of a sealing tape, which costs no more than 100 r / m.

When laying, the following rules must be observed:

Apply sealing tape to glue base necessary on a thoroughly cleaned and degreased base.
Profiled seals are fixed on galvanized self-tapping screws.
It is better to glue the tape at a positive temperature, as the glue will set better.
Gluing is carried out only on a completely dry surface of the roofing.
To accelerate the expansion of the self-expanding tape, it can be heated with a building hair dryer.
The tapes are glued to the joint, without stretching, twisting, or bending.

Remember! To purchase right material for sealing, it is enough to come to any roofing center, knowing the parameters of your roofing. With such a seal, the skate will look more neat and aesthetically pleasing than when using improvised means.

Video instruction

In the process of installing a metal tile, many people ask themselves the question - do I need a sealant for the roof ridge? Many people think it's redundant. headache and it is absolutely not needed - well, how will the sealant of the ridge help? After all ridge tile and lies so tightly on the roof, protects it from precipitation, and the sheets of metal tiles go under it for a few cm - water will not get under the roof in any way. On the one hand, the judgment has a grain of truth. But on the other...

Why do you need a sealer?

Precipitation can get into the under-roof space, even if everything is done correctly, the ridge lies correctly and no unnecessary gaps are left. And the reason for this is the wind. During rain, it can contribute to the penetration of moisture under the roof, and, as a result, the occurrence of fungus and dampness, which will lead to damage wooden structure. And to everything else, snow will definitely be added in winter, during snowstorms snowflakes will get under the roof, melt there - and moisture is provided. And even the most best waterproofing it won’t save here - the rafters will begin to rot, and corrosion will eat up the metal tile. Well, in addition to moisture, I want to keep the roof at least a little clean, and dust, dry leaves, insects will not contribute to this. If a ridge seal missing, then all this dirt will somehow penetrate under the roof. And what about small birds that strive to build housing under the roof? Of course, you need to take care of nature and love birds, but you don’t really want to live with them under the same roof, which, by the way, they can slightly spoil over time.

And one more thing - technical. No matter how correctly the installation is done, gaps and gaps still remain, because the tiles have a profile, but additional accessories for the roof usually do not have one. So there are holes between the tiles and the valley, the ridge, etc. To fix them just need to use sealing material (often they take a universal seal so as not to toil with its installation).
Therefore, in order to ensure a quiet life for yourself, spend a little money and time, lay the sealant on the roof.
The sealant for metal tiles is made of polyurethane foam or is also made of polyethylene foam under high pressure. Despite the "chemical" names, these materials are absolutely safe and environmentally friendly. They will not harm the environment. Possess many useful properties which will certainly appeal to fans of metal tiles.

Here is just a small list of why you should say "YES" to the compactor:

Fire resistance.
Long service life - can serve 90 years without losing its operational qualities. In general, manufacturers of additional “accessories” for a metal roof are very concerned about this: for example, the service life waterproofing film coincides with the service life of the metal tile. Those. it will not be necessary to change anything on purpose - when the roof is dismantled, additional material that has served its time is also removed.
Resistance to moisture, and as a result, to rotting.
Immunity to chemical influences.
Porous structure, elasticity (due to sulfur and soot in the composition). Sometimes there is perforation - for better ventilation. In fact, even without it, the ridge sealing material does not interfere with the ventilation and “breathing” of the roof (including the universal one).

Convenient shape - the sealant is cut in the shape of a metal tile. Or you can use a universal seal for the ridge. It usually has a self-adhesive impregnation applied to one or both sides of the material. The sealant is usually mounted through the roofing, simultaneously with it, self-tapping screws or stainless nails are used for these purposes (if gluing is not provided).
Not afraid of heat and frost - withstands temperatures from - 60 to + 95 degrees Celsius.
Soundproofing. Yes, the material absorbs them well.
Thermal insulation. It is put on the roof, but the skate is ignored. Therefore, the ridge seal under the metal tile will perfectly cope with this task.
Has a thickness of 20 mm.

As already mentioned above, the seals have a different shape - they can be wavy, or they can simply be tape (universal). You can “seal” the area not only near the ridge (on both sides), but also in the valleys (also on both sides), wind and wall slats (on the one hand, of course). For different parts roofs need different seals! Only universal fit for any place. The universal seal can be used for both the ridge and any other parts of the roof that require sealing. A strip of such a seal has a length of 1-2 m, so one is not enough for a roof ridge. Often such a ridge seal is made on an adhesive basis. You can safely put it up to a temperature of 5 degrees, if the temperature is lower, then you need a hair dryer to warm the material. special pre-training the surface on which the seal will lie is not required, even if you are working in the ridge area. Having glued the sealant, we mount the tiles on top of it with self-tapping screws.

LLC Novosibirsk plant "StalPro" recommends using this particular type of sealing material, because it has better air and vapor permeability, but at the same time it retains water and snow and does not let through. Buy this species sealer you can in the sales departments of our factory.

The roof of the house must fulfill many purposes, designed to protect residents from precipitation, provide optimal ventilation rooms and prevent heat loss in the house. The main purpose of any roof is to protect against moisture ingress under the roof. In this case, special attention should be paid pitched roof, because it is in it that the most joints are present. One of the main components of this protection in the arrangement of roofing from metal tiles is a sealant for the ridge.

A metal tile is a roofing material that looks like ceramic tiles, only it is made of profiled steel sheet coated with a polymer. The wave height is approximately 25 mm. At the joints of the roof, ridge strips are used, which come in different shapes:

Simple (triangular);
Tiled (semicircular);
Curly.

Any such product has a straight edge that fits on the wave surface of the coating. In this case, gaps are formed - through them, moisture from the roof can get under the roof. environment. As a result, the roof structure gets wet, due to which the wood of the frame rots, corrosion appears on the metal, thermal insulation properties insulation deteriorate. Therefore, when laying a roof made of such material, a sealant under the ridge of the metal tile should be used. The ridge seal is an important part of the design, which allows you to deal with wetting when arranging a roof made of metal.

Important! most convenient sealing material can be called a universal self-adhesive sealant made of polyurethane foam. In addition, this product is produced figured, which allows you to completely repeat the profile of the metal tile.

The technology of installing a ridge on a roof made of metal

Usually, the installation of the ridge bar is carried out on final stage roofing, when the last rows of metal tiles are laid along the slopes. Its installation should be carried out towards the direction of the prevailing winds in the region.

Most often, for fastening the ridge lath, the crate is supplemented by installing special boards for the ridge above the upper boards of the crate. The gap between such boards of adjacent slopes serves to ensure roof ventilation, it is usually 7-10 cm, this value varies depending on the type of metal tile and the manufacturer's recommendations. Compared to the boards of the battens, the thickness of the ridge boards should be increased by 10-15 mm. This is done so that after fixing the ridge bar does not sink in relation to the wind bar.

The process of mounting the ridge strip on the roof must be carried out according to the recommendations of the manufacturer of the metal tile. Usually these recommendations represent an average option, universally suitable for any kind of ridge strips and various types of metal tiles. Standard installation steps given element roofs include:

First you need to check if the ridge axis of the roof is straight, most builders check this with a stretched cord. The tolerance here is 20 mm. A large curvature will negatively affect the mounted element, because the walls of the ridge will need to be adjusted to the unevenness of the junction of the slopes. Going beyond tolerances defects are corrected.
Then the parts of the skate are prepared. The angle of the ridge strip is adjusted to the angle of the connection of the roofing slopes. To do this, the bar is bent or unbent so that its mounting shelves in a free state correspond to the slope of the slopes. When the slope is above 45°, the bar must be bent sufficiently. Most of all, this affects semicircular skates, because their shape changes significantly after such manipulations. Here, the standard end cap will need to be adjusted to the resulting shape or a home-made overlay made of a flat sheet of steel should be installed.
Installation of the ridge begins from one of the ends. Installed ridge element over end plate, its edge should go out by 20-30 mm. The components of a flat ridge are joined on top of each other with an overlap of at least 10 cm. The details of a round ridge are joined along the stamping lines. On tent types of roofs, T or Y-shaped linings are mounted at the junction of the ridges of adjacent slopes.
The sealant for metal tiles is laid in parallel, it is fixed under the ridge. In the case of a self-adhesive seal, to fix it, you only need to remove it from the adhesive layer protective film and just press it to the desired surface. If there is no adhesive layer on the seal, the adhesive is applied independently. With the use of a ventilation roll, the installation system is slightly modified. Ventilation tape with self-adhesive parts on the side must be glued to the metal tile before installing the ridge trims.

The details of the ridge are attached to the crate or sheet of metal tiles by means of self-tapping screws, twisting them through the wave into the crest of the wave. If you violate this rule and screw the screws directly into the deflection of the wave, there is a risk of deformation of the ridge, which looks sloppy. When fixing the ridge to the metal tile, take self-tapping screws 4.8 by 35 mm, when fixing to the crate through the metal tile - 4.8 by 80 mm.

Important! The most reliable option is to fasten the ridge bar to the crate. This eliminates the separation of the ridge, which is especially important in areas with high wind load.

Some manufacturers of metal tiles advise installing the ridge on a pre-fixed ridge beam. This ensures more reliable installation and optimally even position of the ridge bar. A timber is stuffed along the edge of the roof, its width is usually about 5 cm. Parts of the ridge are fixed on it, screwing them to the metal tile. Having fixed all the elements, check the skate for evenness. If no deviations are found, the work can be considered completed.

The ridge bar is very important element, its correct installation guarantees:

Dry space under the roof;
Decorative appearance metal roofs;
No condensation;
Protection against leaks at the installation site;
Optimal ventilation.

It is necessary to install the skate in compliance with all the rules of the above technique. If there is no experience in such work, it is better to turn to professionals. Regardless of which ridge plank is planned to be equipped: a semicircular ridge of a metal tile, simple or curly - now you can find a lot on the Internet various photos any variation of the ridge for metal tiles and choose optimum material to seal them.

A structure such as a roof has many goals and objectives, it protects against precipitation, organizes ventilation at home, and prevents heat loss. But the main goal of any roof is not to give a single chance for moisture to penetrate under the roofing. Particular attention is paid to the pitched roof, since it is in it that a large number of joints. And the ridge sealant is one of the main assistants in the war against getting wet when installing metal roofing.

A metal tile is a roof covering that looks like ceramic tiles, but made of profiled steel sheet with polymer coated. The height of the wave (step) is about 25 mm. At the joints of the bends of the roof, ridge strips (skates) are used. They can be of different shapes:

simple (triangular shape);
tiled (semicircular);
curly.

But any skate has a straight edge that lies on the wave surface of the coating. At the joint, gaps up to 25 mm deep are formed, through which rain gets under the roofing in summer and snow sweeps in winter. As a result, the structures get wet: the wood rots, the metal corrodes, the insulation loses its heat-insulating properties. Therefore, when constructing a roof made of metal tiles, a sealant under the ridge is necessarily used.

Types of seal

Depending on the shape, the seal can be universal and profiled. Today, when mounting a skate, the following types of gaskets are used:

Rigid specialized. Gaskets are made of high-pressure polyethylene (LDPE) foam with closed cells, they exactly repeat the profile of the metal tile.
Universal self-adhesive. Made from expanded polyurethane foam (PPU).
Universal self-expanding. It is a compressed polyurethane foam tape with an acrylate-polymer impregnation.

Name	Image	Properties
		High level of heat and noise protection. The water absorption index is 1%. Operating temperature from -60 to +95оС. Ecologically safe material. Resistant to UV radiation. Fire safety: B1 (flammable), G2 (moderately combustible). Service life up to 90 years without loss operational properties.
		Operating temperature from -60 to +95оС. Eco-friendly material, resistant to UV radiation, contamination by microorganisms. Does not interfere with the movement of air in the roof structure. Water absorption up to 2%.
		Maximum expansion: 30-40 mm. Operating temperature from -45 to +85оС. The tape is resistant to temperature extremes, UV radiation, precipitation. Does not become infected with fungi and mold. Impregnation does not harden over time.

A comparative analysis of the performance properties of gaskets for metal tiles indicates the following:

Rigid polyethylene foam seal the best performance than polyurethane foam. It dampens up to 70% of noise and prevents heat transfer. But when installing the roof, the organization of ventilation becomes important, and the pores of polyethylene are closed and do not contribute to the movement of air.
All seals are low level water absorption.
Self-adhesive tape shrinks during installation of the roof, and self-expanding, on the contrary, after. However, the PSUL tape can expand enough long time from 1 to 8 hours, and for other material no additional time is required.

Conclusion: Most comfortable material for installation of a roof universal self-adhesive sealant from polyurethane foam. In addition, this type of product is also produced figured, completely repeating the profile of the metal tile.

Price

When choosing a material, most customers are guided not only by specifications materials. It is important to comparative analysis gasket prices:

Other seals

Builders also use other designs of metal tile seals, which are essentially not seals. For example, ridge tape. In addition, it is called the aeroelement of the skate. The woven middle fits comfortably on the ridge beam, without interfering with air exchange, and the corrugated strips with glue along the edges smoothly flow around the wave surface of the metal tile, preventing the penetration of moisture.

Another material used as a sealant is polyurethane foam or polyurethane foam sealant. As a rule, it has good adhesion to most materials, including metal. Winter sealants are heat-resistant: from -40 to + 90 ° C. However, with foam it is extremely difficult to create a neat joint. You have to clean up the excess and paint the surface of the foam. Ventilation of the roof space is also difficult. Therefore, there is no professionally developed technology for using this material for roofing installation. Builders prefer different types seals, but they all agree on one thing: it must be mandatory, as it increases the life of the roof for many years. Watch the video
