How to install a ridge aerator for asphalt shingles. Solid ridge aerator "TechnoNIKOL" for soft roofing: review, installation technology and reviews. The need to use an aerator

As you know, the TechnoNIKOL ridge aerator is used as an element that serves to remove excess sub-roof moisture. It has special protection, a filter based on polyurethane foam, which is designed to prevent the penetration of atmospheric precipitation and insects.

Features Overview

It is used on roofs, it is installed on top cornice tiles, which must correspond to the main color scheme roofs. In this way, you can give the structure an aesthetically finished look and make the aerator almost invisible. For it to work properly, you need to provide air flow from the cornice. Before purchasing, you should become more familiar with the characteristics of the material of the product. The main thing to pay attention to is consumption. For 25 m2 you will need 1 piece. The dimensions of the aerator are 0.61x0.29 m. The color is black.

The aerator is made of polypropylene, this allows you to implement one of the solutions for roof ventilation. The aerator is sold in factory packaging. The product should be stored in dry indoors. Objects of application are:

• residential buildings;
• industrial buildings;
• private houses;
• shopping complexes.

The aerator is installed on gable roof and is compatible with flexible tiles.

Consumer Reviews

The TechnoNIKOL ridge aerator, according to users, is one of important elements properly equipped roof. Its use provides effective ventilation the entire under-roof space. According to buyers, after installation, the materials of the roofing system located inside will be protected from getting wet, and their thermal insulation qualities will remain at their best. Users emphasize that the aerator significantly extends the life of the entire roof and building. You can be sure that the aerator has high quality, since it has a certificate of conformity.

The need to use an aerator

Previously, the TechnoNIKOL ridge aerator was not used, but later, when arranging roof systems, different materials began to be stacked on top of each other. Such a “pie” is responsible today for the preservation of heat, insulation of water and steam. As a result, all cracks through which air could penetrate are closed with a vapor barrier. In this case, moisture accumulates in the sealed under-roof space, remaining in truss structure. The water does not dry out and is supplemented with moisture that comes from outside. Within a couple of years, you will be able to observe fungus spreading throughout the attic.

The TechnoNIKOL ridge aerator has become an important part today Modern roofs require three ventilation layers. The first is located in the internal space of the attic, the second is located between the hydro- and thermal insulation, while the third is under roof space. Create regular air gaps won't be enough. It is important that the air moves from the ridge to the eaves. At the same time, it should not linger so that there is no risk of condensation. Aerators were invented to enhance air circulation and create entrances and exits for moisture. The aero element has a ventilation strip, so birds cannot get inside, and air penetrates and circulates freely. The aerator provides ventilation in individual areas and also guarantees general ventilation.

Installation technology: preparation of tools

Before installing the TechnoNIKOL ridge aerator for soft roofs, you need to read the instructions in more detail, because failure to follow them may cause the element to malfunction. First you need to prepare the tools, including:

• a circular saw;
• cord for marking;
• hammer;
• scissors;
• gun for ;
• roulette;
• mastic in cartridge.

Work methodology

Carried out at which varies from 14 to 45 °. Installation should be carried out exclusively on a prerequisite for this is the presence of vents that provide an influx of fresh air from the cornice. When installing a ridge aerator for a soft roof "TechnoNIKOL", the nails must enter the base 6.3 mm or more. The slots should be spaced away from the edge outer wall 300 mm or more. At the end or beginning of the ridge, aerators should protrude 250 mm above the roof. In order to prevent deterioration in the appearance of the roof structure and building, aerators should be installed along the entire length of the ridge.

It must be remembered that the TechnoNIKOL solid ridge aerator has lockable and closing ends; they are connected when applied and form a sealed and durable structure. Installation must begin from the edge of the ridge of the closing end. As final stage covering the end with a factory ending is recommended. Structural ribs should be placed on a flat top last row tiles, otherwise you may experience leakage. For this purpose, the installation of the TechnoNIKOL ridge aerator may be accompanied by trimming the material and moving the elements towards the partitions.

In order to replace the roof, the first step is to get rid of the old one. ridge tiles. If the roof is new, then you need to immediately cut the base using a circular saw. If you have to work with a roof that has a ridge beam, you need to determine the point where the vent will be located. It is important to provide a gap of 13 mm in each direction. If in front of you is a roof without a ridge beam, then 13 mm must be retreated in each direction from the ridge.

The next step is cutting along the marked line. All openings must be 300mm away from the edge of the external wall or chimney. When installing a TechnoNIKOL ridge aerator, two ridge shingles need to be secured along the edges of the roof. The aerator must be bent to give it the desired shape and facilitate installation. The capping and capping ends should be aligned upon application and no additional sealing will be required.

Conclusion

The TechnoNIKOL ridge aerator, the dimensions of which were mentioned above, must be reinforced with nails at the covering end. Nails are installed in special holes. The aerator baffles must be placed on the flat part of the last row of cover material, otherwise you may experience leaks.

Famous folk wisdom says that every man must build a house, raise a son and plant a tree. If the last two points are a little easier to implement, then with the construction of a house things are more complicated. The main attribute of any building, be it a dacha, a barn or administrative building, is the roof. She will protect the house from rain and from summer heat. But the variety of roofing materials makes owners think about what fits better. And when all doubts are cast aside and the material is chosen, the main thing is small: correct design.

What is a ridge aerator?

Larger role in the choice roofing material now cost and quality play a role. Most often used or bitumen. It is resistant to temperature changes, retains heat well and has a reasonable price.

During its installation, a vapor barrier is used, which should retain the heat coming out from inside the house and protect it from rain and snow from outside in case of damage to the outer layer. But like anyone plastic material, it tends to accumulate condensation.

To prevent moisture accumulation from leading to damage to the wood used during the construction of the roof, it is worth using special plastic or metal device with many holes or a built-in mesh to remove hot air, called a “ridge aerator”.

Types of aerators

Depending on the roofing material and type of roofs, several types of aerators can be used:

• A single aerator is placed pointwise across the entire surface of the roof, this is especially true for isolated and hard-to-reach places. They are divided into ridge and pitched.
• A continuous aerator looks like a long plastic or metal strip, which is evenly distributed over the entire surface of the slope.
• The turbine aerator appeared on the market not so long ago; it looks like a pipe with a built-in fan. This hood makes it much more efficient to remove hot air out.

For roofs covered with metal-plastic, metal constructions with a special coating that easily withstands corrosion and temperature changes. Metal aerators are easily attached to any part of the roof.

The ridge aerator is made from high-quality polyurethane, which can withstand heat up to +90 C and cold down to -40 C. Such parts must be impact-resistant. Most often they are installed at the junction of the upper edges of the slopes.

Is it possible to do it yourself?

In order to understand whether you need a roof aerator or not, you should consult with a specialist. After all, it is most convenient to install these devices while laying the roof. At this time, it is easier to take into account the characteristics of the material, the depth of the protective layer and possible additional insulation.

But if it happens that there is already a roof, and additional work are still necessary, you can try to do it yourself.

The easiest option is to install a ridge aerator. The layer of bitumen squares covering the ridge will have to be removed. Install a ribbon ridge aerator made of plastic or metal under it. Such a corner with many holes and meshes will lift the roofing material at the junction of the slopes. All hot air will rise freely and exit through the holes, preventing condensation from forming.

Things are more complicated with point aerators. Required for installation accurate calculations diameter of the recess for the base of the aerator. If you make it too large, you will have to use additional material for compaction.

First you need to circle the size of the base with a pencil. point aerator. Using a jigsaw or other tool, make a hole, insert the skirt and secure with nails, screws or adhesive. Bituminous glue is applied to the top of the skirt and the tiles are laid so that there are no holes left.

But it is worth remembering that point aerators are installed on flat roofs or with a slope of no more than 12 degrees.

What happens if you don't install an aerator?

Ridge aerator - required part for roofs covered with soft tiles and more. If you are still thinking about the advisability of such an acquisition, then it is worth noting: it is worth it. If you save a small amount now, you'll end up spending a lot more later on replacing your entire roof.

Consequences:

• Rotten beams and ceilings.
• Increased humidity in residential areas.
• Reproduction of mold fungi in the insulation and on the walls of the building.
• Bulging and cracks in roofing material.

If you don’t yet know what a ridge aerator for a soft roof looks like, photos are presented in this material.

But it's worth remembering that this device installed in conjunction with soffits that promote air flow. A ventilation system consisting of spotlights and an aerator will create an excellent microclimate in your home.

The installation of aerators on the roof is necessary, since their presence prevents the destruction of the roofing carpet under the influence of moisture that forms in the under-roof space.

The desire to save on installing roof ventilation leads to many problems: first of all, the roof begins to leak, icicles collect on the eaves, and a damp smell appears in the house. As a result expensive material coatings deteriorate very quickly. The fact is that moisture gets into the thermal insulation layer and elements rafter system.

Decide this problem installation of a roof aerator, which is an artificial ventilation duct. Air circulates through it, drawing out excess moisture and drying the cake structure from the inside.

Reasons for the appearance of moisture in the roofing pie

Manufacturers finishing coatings for roofs they position their materials as airtight, so where does moisture come from in the roofing pie, even though it contains layers of vapor and waterproofing?

Unfortunately, the presence of moist vapors is present in any apartment or house. They are formed as a result of cooking, taking water procedures, washing and breathing of people. According to scientific research, it was found that in houses where a family of 4 people lives, at least 2 liters of water vapor are formed per day. It partially settles in the under-roof space.

When warm steam comes into contact with cold surfaces, condensation forms. As a result, water droplets impregnate the materials and structural elements of the roof into which they can penetrate. First of all, the vapors reach the insulation, rafter system and sheathing.

Another way of moisture penetration is outer side roofs. Warm steam accumulates in the attic and heats the roofing from the inside. Snow gathering in winter period on the roof, starting to melt. As the air temperature drops, ice forms on the roof, and under certain conditions it can also melt. Water penetrates into the smallest gaps between the joints of the coating and leaks form on the roof.

The roofing material begins to gradually become covered with microcracks into which moisture penetrates. At sub-zero temperatures it freezes and tears the roof finish. The cracks are increasingly increasing and turning into through gaps. As a result, the roofing covering becomes unusable.

What is a roof aerator

This device consists of a pipe with a diameter of 6–11 centimeters made of stainless steel or polypropylene. A cap is installed on top of it, which protects the fan from precipitation getting inside it. The aerator helps dry the thermal insulation layer and accelerates the process of evaporation of condensate.

These devices are used in regions with different weather conditions, since they have good operational parameters and withstand temperature changes over a wide range from +90 to -50 degrees.

The roof aerator for metal tiles and other types of roof coverings is intended for the following purposes:

• ventilation of layers roofing pie;
• condensate evaporation;
• withdrawal humid air;
• preventing processes leading to roof destruction;
• preventing leaks from occurring.

The principle of operation of aerators is the appearance of draft in the pipe, which arises due to the low pressure created by external air flows.

Types of roof ventilation devices

According to features design solution, there are several types of roof fans:

1. Spot. Such devices are mushroom-shaped and equipped with fans. They are installed in a place where access is limited - this may be a complex roof configuration or skylights. Point products are divided into ridge and pitched. The first of them are mounted under the ridge - they are intended to remove condensate and vapors along the entire structure of the ridge. This type of aerator is installed in areas that require increased circulation of air flow.
2. Continuous. They are placed evenly over the entire roofing surface and thus ensure ventilation of all layers of the “pie”, as well as areas of attics and attics. The most popular continuous aerators are moisture-resistant ventilation tape, which is installed in the waterproofing layer, and a ridge fan.
3. Turbine. They are produced in the form of a pipe and equipped electric fan or an electric hood. Experts advise giving preference to aluminum products because they are resistant to corrosion and do not change shape when exposed to high temperatures.

When choosing an aerator model, take into account the roof slope. Typically this information can be found on the product packaging.

Choosing an aerator

A certain type of device is used for different roofing coverings. For soft materials Aerators made from weather-resistant and impact-resistant polypropylene are suitable (read also: " "). Usually they are placed equidistant from each other at the highest points of the roofing or at the junction of thermal insulation slabs.

Such a device performs the following functions:

• reduces pressure in the under-roof space;
• removes steam from the layers of the “pie”;
• prevents the appearance of condensation.

The aerator fan housing for metal tiles is made from materials that are resistant to corrosion and aggressive environments, exposure different temperatures and ultraviolet. Polypropylene and stainless steel meet these requirements.

For corrugated sheet coverings, the same materials are used for the deflector body as for metal tile roofs.

Installation of ridge aerators

Installation of devices of this type is simple, and there is no need to make complex calculations. The ridge aerator is placed along the entire length of the ridge. Experts recommend using this product for roofs with a slope of 12 to 45 degrees. It is mounted exclusively on the ridge and thereby provides air ventilation in the attic space.

Conditions for using the ridge aerator:

1. In order to ensure air flow, it is necessary to have vents on the eaves.
2. The device should be mounted along the entire length of the ridge - its segments are connected into a single structure.
3. Ridge tiles are laid on top of the assembled product, and therefore appearance the roof will not be damaged by the presence of a fan on it.

The installation of a ridge aerator for metal tiles or soft roofing is carried out in a certain sequence:

1. To cut the ventilation groove, use a circular saw. There can be either one hole (at the top point of the ridge) or two (on both sides). Depending on the manufacturer’s recommendations for a specific aerator model, the total gap thickness should be from 3 to 8 centimeters. The slots are cut so that they do not reach the edge of the ridge by about 30 centimeters. As a result, the roof on its sides is continuous.
2. In the place on the ridge where the gap was not made, ridge tiles are laid.
3. They begin to install the aerator: each of its segments is fixed with roofing nails or screws, which are screwed in through ready-made holes made at the manufacturing plant. The individual parts of the product are assembled into a single structure in the same way as is done with the parts of a construction set.
4. The profile of the ventilation product is covered with ridge tiles - the petals of the roofing material are overlapped. Long special nails are used to attach the covering to the ventilation device.
5. The places where the ends come into contact with the roof are treated with silicone sealant.

Features of installation of point devices on metal tiles

Aerators of this type are installed:

• on flat roofs or on roofs with a slope of less than 12 degrees;
• as a complement to another type of device in order to increase ventilation efficiency;
• if it is not possible to install a ridge product, for example, because there is no ridge, or there is an abutment of the roofing to walls or vertical surfaces.

Conditions for using a point aerator:

1. They are mounted on the slopes, maintaining a distance of 50-80 centimeters from the horizontal edge of the ridge.
2. Air flow must be ensured on overhangs.
3. One point device can provide high-quality ventilation on an area of ​​up to 5 - 100 “squares” of roofing, depending on its model. Based on this value, the required number of ventilation products is calculated.

Technology for installing point devices on the roof:

1. IN continuous lathing make a hole whose dimensions must match the parameters of the internal channel of the aerator. To do this, apply the base skirt of the device to the surface of a sheet of plywood or OSB board and, through the passage channel, mark the contours of the gap on the roof with a nail or pencil. Using a jigsaw, cut a hole along the drawn line.
2. The skirt of the device is placed on top of it and secured with screws or roofing nails in an amount of at least 6 pieces. Some manufacturing companies recommend using, in addition to fasteners, fixation on adhesive composition. In this case, apply to the back surface of the skirt bitumen mastic, glue it, and then only use the parts for fastening.
3. To waterproof the junction areas, bitumen glue is used over the skirt.
4. Shingles of tiles, trimmed at the points of contact, cover the skirt.
5. An aerator mesh is placed on top of it and secured with self-tapping screws. Then they install the cap (lid), snap it on and again use self-tapping screws for fastening.

Other point aerators for the roof are installed in a similar way according to the calculations made, which will ultimately amount to unified system ventilation.

As can be seen from the above information, the installation of such devices is not difficult work- inexperienced self-taught craftsmen can easily handle it.

Thanks to the presence of aerators on the roofs, water vapor is removed from the roofing pie, the formation of condensation and the spread of fungus and mold are prevented, unpleasant odor. The absence of these unfavorable factors has a positive effect on the service life of wooden roofing elements and on the state of the microclimate in residential and utility rooms Houses.

How to install roof aerator on bitumen shingles, soft roof. Installation of ktv ridge point valve.

For installation roof vent necessary:

• roofing nails with a wide head, which are used for installing soft roofing ( bitumen shingles);
• bitumen roofing adhesive (roofing mastic);
• electric jigsaw, spatula.

Installation of a ridge point valve

The aerator is installed at a distance of no more than 1.0 meters from the roof ridge line, according to the rule “the higher, the better.” It is desirable that the upper edge of the KTV flashing be located 2 cm below the ridge tiles (approximately 20 cm from the ridge to the top of the flashing).

Using a hammer, roofing nails punch out evenly in three circles relative to the ventilation hole of the flashing.

Sizing

After the flashing is installed, it should be glued with roofing bitumen glue.

You can glue it either gradually as the aerator passes through the roof, or after the aerator flashing is covered.

To do this, when installing the roof in the areas of the aerators, the roof is nailed so that it is possible to unfold the roofing tiles and glue the aerator flashing.

Apply bitumen adhesive using a spatula in a minimal layer.

Coat the entire flashing and the joint between the flashing and the roof. After applying the glue, the bitumen tiles are installed. It is important that nails do not get into the flashing. punching nails in the right places.

Afterwards, the aerator mesh is placed on the flashing, which is screwed onto the flashing with three self-tapping screws (one at the bottom and two at the top of the aerator). Manufacturers usually put marks on the aerator mesh for scrolling. On the back of the aerator mesh there is a special spike on which the aerator cover is placed. Put the lid on, snap it on and screw it to the mesh with two self-tapping screws. Self-tapping screws should be no longer than 35 mm, so as not to make holes in the roof.

The roof should always be dry. But we're not talking about her now. outside, but about the multiple internal layers of the roofing pie. At the same time, it must be dry regardless of the materials used for finishing, be it slate, or a soft bitumen coating. Condensation and moisture accumulated in the under-roof space can quickly render the entire roof unusable and significantly reduce its service life. To avoid excess moisture inside the pie, you will have to install aerators for the soft roof. Let's look at what they are and how they are installed.

To understand why it should always be dry under any roof, you first need to figure out where water can come from there and condensation can form. After all, when building a roof, craftsmen always try to make it as airtight as possible, laying various waterproofing and vapor barrier materials, which in theory should provide reliable protection.

The whole point is that Various processes related to human life take place in a residential building. People breathe, cook, take a shower or bath. And during all these processes, the air in the house is saturated with steam - in other words, it becomes humid. Warm air rises and gets trapped under the roof if it doesn't have a way to escape through a vent. At the top, microscopic droplets of water settle on various materials– this is how condensation forms. At the same time, air saturated with water vapor easily penetrates even the most inaccessible places through microcracks.

On a note! During the day, a person exhales about 1 liter of liquid into the air in the form of vapor. Adding to this amount all the water that gets into the air during cooking, washing floors or taking a bath, you can get a huge figure - up to 15 liters of water enters the air in the house during the day.

The accumulation of condensation under the roof poses a certain danger to all materials that make up the roofing pie. Wooden elements begin to become saturated with water, which causes rotting processes to occur. This environment is also favorable for the development of fungus and harmful microorganisms that are dangerous to the health of people living in the house.

Metal elements (for example, fasteners) inside the roofing pie due to higher level humidity begin to corrode and gradually collapse. If water in the under-roof space, accumulated during the summer, freezes in winter, it can easily damage some structural parts (even concrete floors), since, expanding, it will exert a pressing effect on the materials. Due to severe damage, the roof may even have to be completely dismantled and rebuilt.

Also, exposure to moisture is detrimental to insulating materials. If they get wet, their thermal conductivity will increase significantly. This means that such a roof will no longer be able to retain heat well. In some cases, the insulation will need to be completely changed, because it will no longer be possible to fully dry it.

Moisture can reach the structural elements of the roof and the outside. During heavy rains or melting snow, water can still find a hole and get under the roof or into the roofing pie, even if its outer surface is well sealed. This option of additional “humidification” should not be excluded.

On a note! In terms of vulnerability, any soft roof suffers the most from excess moisture under the roof.

Soft roof and water

As for the soft roof, moisture actively accumulates under it in the insulating layer. At a minimum, this can cause the roof to bubble, especially if we are talking about soft bitumen coating, laid on a flat concrete roof. In this case, bubbles may occur here's why: in summer the roof can easily heat up to 90 degrees or more. Soft materials always contain bitumen, which is a thermoplastic substance - it reacts sharply to changes temperature regime(may become brittle in cold weather or soft and plastic - when hot). When the material is heated above 50 degrees, the plasticity increases, and the quality of adhesion of the coating to the base depends, for the most part, not on adhesion at all, but on the viscosity of the components included in the material or the mastic to which the coating was glued.

Defect of ordinary roofing - formation of swellings of the roofing carpet

Between the vapor barrier and waterproofing in the roof pie there is a closed, sealed space. As the temperature rises, the pressure in this area increases to 2-2.5 t/m2. The waterproofing lifts up, lifting the roof covering, and thus bulges form.

To get rid of all the above problems, It is necessary to install an aerator during roof installation. It will ensure the removal of air to the outside, and with it moisture. The device will allow you to dry the heat and waterproofing layers and prevent the accumulation of condensation.

What is an aerator and how does it work?

A roof aerator is a design that serves to remove moisture from under the roof, including that which has formed in the roofing pie itself, and not just in the house. This element can be installed on the most different roofs, having all kinds of slope angles and covered different materials. An aerator on a soft roof will prevent premature destruction of the entire roof structure due to exposure to moisture.

Inside the installed aerator, draft is created due to the formation of a low-pressure area due to external wind flows and the pressure difference in the space under the roof and the street. The main functions of this design are as follows:

• removal of water vapor from the house to the outside;
• reducing the pressure between layers inside the roof (reducing the risk of bubbles on flat roofs);
• reducing the risk of condensation forming on waterproofing materials.

Externally, the aerator is a pipe with a cross-section of 63-110 mm, with an umbrella on top that protects the structure from rain and snow getting inside. It can also be represented in the form ridge strip with bars on the sides. The first aerator is installed on the roof slope, and the second variation is installed along the roof ridge.

On a note! The aerator can be installed during construction or on a finished roof.

Types of aerators

Aerators may differ from each other in materials of manufacture and design features. Most often used plastic products, however, there are also metal ones (made of steel) on sale, which are usually mounted on metal tile roofs. In fact, all aerators are resistant to sunlight, rust, temperature changes.

Table. Types of aerators depending on design features.

On a note! The aerator market is now quite extensive and makes it possible to choose this structural element of such a shape that it can look organically on a roof of a certain type or style.

How to install?

The installation of aerators can be done both during the installation of the roof and after the work is completed. In general, this structural element is not difficult to install if you know how to do it. The instructions will help you understand the installation steps ( installation of a point aerator in a finished roof).

Step 1. A template cut to the size of the section of the lower part of the aerator is fixed on the surface of the bitumen shingles using self-tapping screws. You can circle it with a marker or carry out further actions directly along its contour.

Step 2. A hole is cut in the roof using a jigsaw according to the shape of the template. During cutting, it is important not to damage the waterproofing and insulating layers.

Step 3. If the template was screwed, then after cutting a hole in the roof it is unscrewed and removed.

Step 4. The cut out pieces of roofing and sheathing are removed.

Step 5. Using a vacuum cleaner, particles of debris and sawdust are removed from the roof surface and from the resulting hole.

Step 6. Rubber-based glue is applied around the perimeter of the aerator base.

Step 7 The aerator is turned over and glued around the perimeter of the hole cut in the roof.

Step 8 The base of the aerator is additionally fixed to the roof surface with self-tapping screws. For ease of work, the top cover of the aerator can be removed.

Step 9 After the aerator has been securely fixed to the roof surface, top cover returns to place and screws on.

Attention! If several aerators are installed on the roof, then it is important to ensure that the gap between them does not exceed 12 m. In general, per 100 m2 flat roof 1 aerator is used. On a roof that has ridges and valleys, aerators are mounted near the ridge.

Installation of a ridge tape aerator

Let's also look at an example of how it happens installation of a ridge aerator.

Step 1. The roof base is prepared for the installation of a ridge aerator. An opening 5 cm wide is made along the ridge, 2.5 cm on each side. On each side of the skate, 20 cm is measured along it. This minimum distance which should not be cut.

Another photo of the process - 20 cm is measured

Opening width - 2.5 cm on each side

Step 2. For roofs with central beams, a 9 cm wide slot is made, 4.5 cm on each side of the ridge.

Step 3. The ridge is ready for ventilation installation when the remaining tiles and beams, as well as all debris, have been removed from the surface.

Step 4. The ridge aerator is quite flexible and is sold in reels. It is rolled out along the entire length of the skate from edge to edge, including places without slots.

Step 5. The edge of the ventilation tape is fixed with nails, two from each slope.

Step 6. The fixed tape is well stretched and fixed at the other edge of the ridge. If the roof is long, then you can fix the tape in stages.

Step 7 Excess aerator tape is cut off.

Step 8 End caps are installed. Mastic is applied to them on both sides. They should cover both edges of the moisture-proof membrane between the end cap and the bottom vent.

Step 9 The tape and edge cap are nailed to the base of the roof as shown in the image. At least two nails must go through the tape and the plug.

Step 10 A layer of mastic is applied between roofing covering and ventilation tape.

Step 11 The part of the tape that has not yet been fixed is nailed to wooden base roofs. Nails must penetrate to a depth of at least 1.5 cm.

Step 12 To cover such ventilated ridges, you will need pieces of bitumen shingles; 3 tile elements are stacked together on top of each other.

Attention! If work is carried out in the cool season, the tiles must be preheated.

Step 13 The roof tiles are laid on the ridge starting from the windiest side. The first three-layer element is nailed to the roof through the aerator. An indent of 2.5 cm is made from the edge of the tile - a nail is driven into this point.

Step 14 The second three-layer tile element in a row is laid so as to cover the nails on the previous element.

Step 15 The entire ridge is designed in the same way.

A roof aerator installed on the roof will provide the house and the roof itself with good ventilation. It will not allow condensation to accumulate and will not allow water to destroy the structural elements of the roof. Installing the aerator is not difficult; anyone who has carefully studied the instructions given above can handle the task.
