The roof ventilation outlet is the final element of the ventilation or aerator system through which the pipe exits. The products ensure the tightness of the junction of communications with the roof, and also provide an aesthetic appearance node. So-called fungi protect the ventilation system from precipitation and wind blowing.

The need to pass ventilation pipes through the roof is due to the fact that this method allows creating natural cravings in system. Positioning the output at a height will ensure the creation comfortable atmosphere indoors, will speed up the removal of waterlogged and polluted air from the kitchen, bathroom or workshop.

The most important advantage of roof hoods for exhaust hoods is that they eliminate the need to create a bulky brick riser. The sealed outlet allows pipes to be laid in any in a convenient way. The use of such a design is much cheaper, its installation requires less time and money, ready-made solution does not spoil the appearance of the roof and does not require any maintenance.

Constant and high-quality air exchange under the roof guarantees a long service life of both the roof itself and the entire building. The comfort of people living in the house also depends on ventilation, since it plays a key role in shaping the microclimate.

Peculiarities

Ventilation soft roof is not an independent process. On the contrary, the presence or absence of ventilation in the premises directly affects the exchange of air in the roof. To effectively remove destructive moisture from residential premises through the roof, it is necessary to analyze the ventilation of all elements of the house as an integral process.

If the roof configuration is complex, has many transitions and valleys, the process of removing exhaust air must be divided into sections and air flows in the roof must be organized separately.

As a result good ventilation the air in the space under the roof should change approximately 2 times per hour.

The performance qualities of a ventilated roof depend on the slope of the slopes. The steeper they are, the more intense the ventilation process occurs.

And, on the contrary, in roofs with a slope of less than 20%, ventilation of the under-roof space is unstable and effective only under wind pressure.

A useful addition is the construction of auxiliary exhaust components (aerators) on the roof, which help to enhance the natural ventilation of the roof. They should be installed on roofs of complex configurations, when ordinary means are no longer sufficient.

Aerators are installed near the ridge. In roof coverings made of fused materials, consisting of two layers, aerators are installed on the bottom layer of material.

The thermal characteristics of insulation and the durability of roof structures directly depend on the presence of moisture in them.

As a result, a ventilated roof and room ventilation device are economically viable, even when forced air exchange is required.

Advantages and disadvantages The main purpose of the ventilation system is to ensure the passage atmospheric air

, facilitating the extraction of heat from under the roofing to the outside. The exhaust air provides ventilation to the attic.

If under-roof ventilation is done correctly, then such air flow occurs naturally and there is no need to use additional mechanical equipment. Aerators are produced various diameters Their size and quantity are selected depending on the roof area from flexible tiles.

Having a ventilated space under the roof has the following advantages:

• stable cool and dry condition of the attic;
• outside air from attic space able to leave naturally;
• load-bearing roof components, coverings and thermal insulation layers are not exposed to high humidity;
• absence of conditions for the formation of mold and rot, prevention of damage finishing materials roofs;
• reduction in electrical energy costs.

Experts have found that when using soft coverings the main disadvantage is the accumulation excess moisture in screed and thermal insulation.

High humidity of these roof layers provokes a number of negative consequences, such as:

• Bloating roof covering resulting from its heating in summer due to delamination bitumen-polymer materials under the influence of high temperature.
• Increased thermal conductivity causes accumulated under waterproofing material moisture, which impairs thermal properties. It has been theoretically proven that with an increase in moisture content by 1-2%, the heat-conducting properties of the material increase by 30-40%. This leads to increased costs for heating the facility. Along with heat loss, oversaturation of roof layers with moisture can lead to the formation of mold.

• Destruction of the waterproofing layer and screeds are caused by the penetration of moisture into the material. After the temperature drops surrounding atmosphere The moisture absorbed into the material crystallizes and its volume increases. This process entails the appearance of microcracks and destruction of the screed. Similar negative processes occur in the waterproofing layer, destroying its integrity.

Varieties

Roof aerators come in various designs and sizes. They are used to ventilate the space under the roof, eliminate condensation and remove moist air outside. Before purchasing an aerator, you need to understand the features of their design and types.

Spot

These aerators are called differently roof point valves. They are mounted on roofs that do not have a ridge - hipped and flat. Myself roof aerator made of high-strength plastic, resistant to mechanical stress and impact sun rays(burnout).

It has 4 parts in its structure: a flask, a protective umbrella for it, a tube and a filter mesh.

According to the configuration of the flask, they are divided into flat and bottle. Bottle roofs are installed on single-pitch and hip roof types, and flat roofs are installed on flat roofs. Such aerators function productively if they are placed evenly throughout the roof. As a rule, one deflector is needed per 20 m2 of roof, but, if possible, it is better to install two.

Skate continuous

According to the name, they are installed on pitched roofs equipped with a skate. Represent permanent output, located at the very top of the slope. The ridge aerator is implemented in the form of a square equipped with through holes, which are called vents.

Ventilations can be point vents (made at a distance of 6-8 m from each other) and slot vents (5 cm gap). There is a protective mesh to prevent insects from entering the roof. Similar device is mounted along the entire ridge and attached to the roofing material. Its individual components form an integral system. The aerator perfectly retains moisture and allows air to pass out, preventing it from stagnating in the attic.

How to choose?

On soft roofs, various deflectors are used, the choice of which depends on the type of roof.

When choosing an aerator, preference should be given to products that have certificates from a trusted manufacturer.

At the time of buying Special attention It is required to pay attention to the completeness of the set and the absence of mechanical damage (scratches, chips, cracks and deformation).

When choosing aerators for a soft roof, you need to take into account the complexity of its structure, the climate and the level of moisture saturation in the attic. As a rule, one point aerator must be installed per 100-150 m2.

When installing a ridge aerator, a different approach is used. A ventilation gap is constructed along the entire length of the joint, and air enters from under the overhangs, where a specialized aero element (perforated tape) is placed on the gap.

All types of aerators come with a range of technical specifications which they must comply with:

• withstand temperatures from -50? C to +100? C;
• resistance to chemicals, which may be contained in sediments;
• corrosion resistance.

How to install?

Each type of aerator has a specific installation procedure.

Point devices are mounted on flat roofs and roofs with an inclination angle of less than 12 degrees. They can also be used as a complement to ridge aerators.

Let's take a closer look at the technology for installing point aerators:

• We determine the location of the aerators. Place the base of the aerator on the installation site and trace the outline with a pencil. According to the applied mark using electric jigsaw make holes.

• We install the skirt (base) of the aerator over the finished hole and fix it with self-tapping screws or nails. For a stronger fixation, you can additionally use glue. In this case, apply to the inner segment of the skirt bitumen mastic, glue to the base and secure with nails.
• Coat the top of the skirt with bitumen glue.
• We cover the skirt with soft tiles, cutting the shingles at the points of contact.
• We put the aerator mesh on top of the skirt and screw it with self-tapping screws. Then we install the cap (lid), snap it in place and also screw it in with self-tapping screws.

We install the remaining point aerators in the same order.

Installation of a ridge aerator is quite simple; it is installed along the entire length of a pitched ridge and its variety - a hip roof, the slope of which ranges from 12 to 45 degrees. There are two methods for installing a ventilated soft roof ridge.

Installation technology:

• In a solid base through circular saw cut a ventilation groove. It can be single (at the highest point of the ridge) or consist of two parts (on the sides of the ridge). The total thickness of the ventilation gap should be 3-8 cm (depending on the instructions of the manufacturer of the aerator used). The ventilation groove should end 30 cm before the edge of the ridge on both sides, that is, the covering remains continuous.

• Areas where the ventilation gap has not been cut are covered with ridge tiles.
• We install the aerator. Each section is fixed using special roofing nails or screws screwed through existing factory holes.
• We lay ridge tiles on top of the aerator profile. We lay its petals overlapping, using standard installation technology along the ribs. The only difference is the fastening elements. In this case, we nail the tiles to the aerator with special roofing nails.

• We seal the joints between the aerator and the roof with silicone-based sealant. It is necessary to ensure that a depression does not form around the device for ventilation of the under-roof space. These depressions will retain water and snow, which over time will certainly find a place to seep under the roof.

The second method involves fixing wooden blocks at the highest point of the roof slopes. It turns out to be a kind of lathing for the ridge strip. We nail plywood strips to the top of the bars, forming a triangle. We form ventilation gaps between the bars, and cover the entire structure, as in the previous case, with shingles.

If the height difference on the roof is quite large and the total height of the structure is at least 7 meters, then instead of aerators, small box valves can be installed together with ridge ventilation.

Houses with hip or hip roof architecture do not have gables. But this is not a problem for the ventilation device. It is based on the same principles as gable roofs, but at the same time we must not forget that it is necessary to construct inlet gaps to ensure the passage of air along the entire perimeter of the roof. How many stingrays hip roof would not have, each of them should be ventilated.

A half-hip roof gives a great desire to forget about the ventilation of the space under the roof, since its inclined end elements have relatively small dimensions. The ventilation system here can be built according to the principle of ventilation on the main roof slopes.

It is a little more difficult to calculate the ventilation of the end slopes of a Dutch (hip) roof, since there is a window directly above them. This is an obstacle to the use of pipes, but, nevertheless, an aerator or grilles can be installed there.

During the operation of a residential building with a roof made of soft roofing materials great importance has soft roof ventilation.

The comfort, reliability and durability of housing largely depend on it. Roof ventilation maintains integrity roofing, prevents corrosion of metal elements, the formation of mold and mildew, rotting of insulating layers, wooden beams inside a complete structure.

Thanks to full air circulation, the building “breathes” at all levels “fully.”

Important reasons for installing ventilation

Most private houses in the past had pitched roofs with cold attics. Ventilation of the under-roof space of such structures was carried out naturally.

On opposite gables of the house were installed dormer windows, through which fresh air could penetrate into the attic.

Due to the difference in pressure from inside and outside, air moves, which enters inner space the attic, heats up, rises and is discharged through the roof. In this way, natural circulation occurs.

Modern private houses thanks to the latest construction technologies very well insulated at all levels.

The attic space is being lived in: heating systems are being installed there and fashionable attics are being built.

In addition, when constructing the roof of a house, waterproofing, vapor barrier and an insulating layer are installed.

Such designs require installation reliable system ventilation. The need for effective ventilation is due to the following reasons.

First, traditional hearing ventilation windows often do not work efficiently and do not provide proper air circulation.

As a result, zones with stagnant air appear inside the space under the roof. This contributes to the appearance of dampness.

The situation is aggravated in cases where the dormer windows are closed for some reason.

Secondly, under the influence of the hot summer sun outside surface the roof heats up to critical temperatures.

As a result, moisture collected inside the roof structure due to the lack of ventilation ducts evaporates and comes out along the shortest path in the form of steam.

The consequence of this may be the destruction of the roof made of soft coverings due to their swelling.

On the other hand, staying inside the attic space at such a time becomes very uncomfortable, since the temperature there rises greatly.

Thirdly, during the off-season, in autumn and spring, large temperature changes occur.

As a result of this, due to the contact of cold and warm air condensation forms under the roof, which saturates all layers internal structure roofs, destroying them.

Under the influence of moisture, mold, mildew, and rust form on metal elements roofs. Thermal insulation saturated with moisture cannot fully perform its functions.

Fourthly, in winter time year snow cover on outside the roof melts under the influence of warm air, which collects inside under the base of the roof.

As a result, ice forms, which, when heated from the inside, melts and releases water that penetrates through the seams of the roof from soft tiles inside.

As a result, leaks form in these places, destroying the roof from the inside. Thus, the first sign of insufficient ventilation is icicles.

Types and functions of soft roof ventilation for pitched roofs

Roof ventilation works at physical principles movement of warm air from bottom to top.

By ensuring uninterrupted air circulation through all layers of the roof structure, the following most important tasks are solved:

• preventing the attic space from heating up from the roof, which is hot in the hot summer sun;
• getting rid of condensation that has formed under the roof from damp lower vapors;
• ventilation of the inside of the roof to prevent the formation of ice in winter.

A ventilation device for a soft roof involves designing the entry point fresh air.

Entrances are usually located along the perimeter of the roof and are protected from insects and birds by strips, perforated soffits, and decorative grilles.

Cold air passes through such “gates” under the soft roof and is discharged through point aerators to external roof or “ridge” installed on the edge of the connection of two slopes.

Roof ventilation for soft coverings can be continuous or spot.

A striking representative of continuous outlet ventilation, which is located on the edge of the connection of two roof slopes, is ridge ventilation.

Such a system is mounted on the upper edge of the roof along its entire length. Ridge aerators are connected into an integral system that provides effective ventilation the entire space under the roof.

These elements are equipped with built-in filters that trap a variety of debris from the external environment.

At the same time, they have a soft flexible structure, they are easy to install. Such ventilation systems covered with soft roofing materials that create an aesthetically attractive surface for the roofs of private houses.

Point aerators are placed evenly over the roof surface in increments of 10 - 12 meters. Moreover, one such ventilation element in the form of a fungus effectively ventilates an area of ​​60 m2.

Such ventilation devices installed on the base of the roof, penetrating roofing pie up to vapor insulation.

After installation, they are carefully insulated on all sides, and a soft roof is laid on the sides.

Eaves ventilation is provided by:

• special roofing elements with vents that are installed above the overhangs;
• lining the roof with special perforated soffits;
• PVC gratings embedded in the soffits.

Working as a single mechanism in clear interaction with all its elements, such ventilation systems provide high-quality ventilation of the entire roof structure of any building.

For greater efficiency, ridge ventilation is often enhanced with point aerators. Such complex ventilation works more efficiently.

Ventilation devices for flat soft roofs

Reasons for installing flat ventilation systems soft roofs the same as in the case of pitched analogues.

Common universal problems in different seasons are typical for rolled, membrane roofing materials and liquid rubber. When flat roof The use of weather vanes, aerators, and vents is very important.

This is due to the popularity of using vapor-tight rubber membranes as roofing materials.

With such a roof covering, water from condensate, when accumulating critically, can only go down, causing leaks through the ceiling.

Properly installed in technically ventilation will ensure the long life of the soft roofing covering of a flat roof.

In such cases, special ventilation devices: inertial turbines, electric fans, ventilation nozzles that are installed vertically under special “umbrellas” over the entire area of ​​the flat roof.

Among these options are inertia turbines, which are characterized by high performance, low price and efficiency.

Such ventilation elements have the following advantages:

• used to rotate the turbine free energy wind, which is sufficient even in small quantities;
• due to rotation, a vacuum is formed inside the channel, enhancing the flow of air flows;
• Due to its operation, the ventilation turbine increases the efficiency of thermal insulation in cold weather by removing moisture, and in hot weather it keeps the space under the roof cool.

All aerators are installed according to similar scheme, sequentially in three stages:

• first you need to cut through the coating to the vapor insulation layer when installing new roof, and in the case overhaul– through all layers to the base;
• install the aerator and secure it with self-tapping screws;
• strengthen and seal the joints of the units and the coating.

A properly installed aerator ensures the movement of water suspensions and vapors to its base, and after that they are discharged outside.

Ventilation ducts leading onto the roof are insulated and covered with a deflector cap.

To ensure the tightness of exits on the surface of a soft roof, special collars and rubber seals are used, which are coated with bitumen mastic for better sealing.

Options for creating attic ventilation

Proper ventilation under the roof allows you to avoid numerous problems when using a soft roof.

At the first stages of arranging ventilation, it is important to ensure a flow of fresh air from the environment.

On the lower part of the roof eaves along the perimeter, special perforated soffits are installed to delay the penetration of debris and limit the access of insects and birds. In this case, it is necessary to leave a gap of a certain size.

To ensure constant ventilation of the space under the roof, they are used various devices: electric fans, inertial turbines, ridge ventilated over the entire area, roof point aerators.

For proper arrangement ventilation, it is better to rely on the advice of experienced professionals:

• when the roof length is more than 10 meters, it is advisable to use additional elements ventilation;
• ventilation ducts on eaves and ridges must be protected from the entry of insects, birds, leaves and various debris into them;
• gaps must be made of certain sizes, since increasing them does not guarantee an increase in the quality of ventilation, and may have the opposite effect;
• ventilation ducts should be located freely, without unnecessary bends or structural obstacles.

Proper roof ventilation with a soft roof has a beneficial effect on the entire structure as a whole, so when carrying out work it is necessary to pay maximum attention to this and take it as seriously as possible.

Roofing from soft materials has always been distinguished by its uniqueness. Developers, accustomed to seeing only rigid products on the roof of buildings, note that with elastic materials and correct selection auxiliary elements the building looks more comfortable. The most attractive thing about soft materials is their price. Indeed, covering a roof with them is not expensive, but in order to create a high-quality structure, you need to think through all the nuances. One of them is roof ventilation.

When installing a covering made of soft tiles, you should understand that this material is a kind of waterproofing and will not allow moisture to pass through, therefore, condensation that gets into the attic space will remain there for a long time. It is about solving this problem that this article is written.

Flexible roof

Before answering your question, I want to tell you a little about the softest roof.

Judging by this coating only based on the characteristics, then it’s straight perfect coverage, but as you know, such things don’t happen, so let’s look at the positive and negative qualities this product and let's start with the good stuff.

• Good sound insulation. When it rains, a person in the house will never hear the sounds of drops falling on the roof
• High performance. It is thanks to its structure and the raw materials used in production that the material will never begin to corrode, rot or become covered with microorganisms in the form of fungi or moss
• Easy to install
• There is no need to equip its surface with special elements such as a lightning rod, because the bitumen coating includes materials that do not allow current to spread
• Due to its small dimensions and plasticity, it is not afraid of temperature fluctuations and strong gusts of wind.
• Unpretentious during operation
• Cheapness
• Soft roofing is a sealed and environmentally friendly product

Now, let's touch on the negative side.

• At low temperatures, the material becomes very fragile, so its installation during this period is simply impractical
• The installation process should be carried out only in positive temperatures, when the air is heated to more than 5 degrees. If there is an urgent need for this, then it is necessary to use heating devices
• The minimum slope for the roof is at least 10 degrees (but some products can be laid on slopes up to 5 degrees)

Well-known manufacturers of flexible roofing

If you decide to buy this product, then you certainly should know about the common manufacturers of this material.

1. All over the world, the most common flexible roofing is Kerabit. These are soft tiles that are produced in Finland, and the company Lemminkainen is engaged in this
2. If we consider the CIS countries, then developers here most prefer the company Katepal, located in Finland and Shinglas. Katepal has an average price, which is reflected in its quality, but Shinglas has a fairly low price for its performance. The company has 5 types of products in its arsenal, which differ not only in size, but also in shape

How experienced builder, I can assure you that best choice of the three options will be Shinglas brand products. Compared to its analogues, it has a great advantage in:

• Resistant to direct sunlight
• Protection against the proliferation of microorganisms
• Chemical resistance
• The harsh conditions of Russia

When you come to a hardware store, you should not immediately ask about the brand you are interested in, ask the seller about other materials, soberly weigh all the pros and cons, and only then purchase the product.

Main components of soft roofs

So let's look at what layers it includes flexible roofing. We will analyze the layers using the example of tiles, but if we consider roll material, then you will not see significant differences.

1. Roof covering
2. Underlay carpet
3. Lathing (solid, OSB board)
4. Vapor barrier layer
5. Thermal insulation boards

These layers may not fit in this sequence. It all depends on the roofing material and functional purpose building.

I would like to raise a separate topic regarding lathing. After all, the service life of your roof will depend on it.

As part of a rafter system for soft roofs, sheathing plays quite a role. important role. It is fastened to a counter lath, which is created to provide ventilation passages, which allows condensation to be removed.

To create a high-quality sheathing you will need the following materials:

• Board made of coniferous trees.
• Moisture-resistant plywood or, as an alternative, OSB board. It is worth noting that the larger the pitch of the rafter legs is set, the thicker the plywood sheet is taken.
• Long nails.

IN regulatory documents you will not find the requirements for sheathing, which I will describe below.

• The sheathing should be created without any steps or irregularities.
• All joining of elements must be carried out as efficiently as possible.
• If the attic space will not be converted into a living space, then you should not make it very bulky, it is enough just that it can withstand the design loads.
• There should be a small gap of 1-3 millimeters between the boards. This will allow air masses to ventilate the space.
• All wooden parts rafter system must be treated with antiseptics (substances that prevent rotting).

The fasteners for the sheathing must go through all the boards. By the way, to improve the quality of this design, these places can be processed.

Installation of flexible roofing

After you have learned almost everything about the rafter system, you should understand the tile installation process itself.

The process looks like this:

• First, as elsewhere, you should carry out preparatory work. They include cleaning the base from debris and drying it (if required), and treating it with various solutions.
• A continuous lining carpet is laid over the continuous sheathing (despite its name, there should be a small gap of 1-3 millimeters between the boards), and if it is not possible to completely cover this plane with one sheet, then the parts are glued together using special construction tape. remember, that this work It is advisable only on roofs with a slope of less than 20 degrees, and if this value is greater, then the lining carpet is arranged in the most dangerous places. By such places I mean areas where leakage is possible in the future.
• After this, in eaves overhangs and the ends of the building are arranged metal strips and cornice tiles.
• Next, the work moves on to arranging and strengthening the valleys (if any).
• As soon as the previous work has been completed, you can begin laying ordinary tiles along the entire roof plane, but without affecting the places where the ridge tiles will be installed.

I hope everything is clear to you here and now you can move on to the main thing.

How to create high-quality ventilation on a roof made of flexible tiles

Ventilation allows air to remove excess moisture from the attic and some important rafter nodes, but if you leave it there, what could it turn out to be?

If you do not provide the roof with ventilation, then you will certainly face the following consequences:

• The warm season will turn your attic into a steam room, therefore, you will not be able to stay there for a long time or store anything.
• The insulation boards that are located in the roofing pie will fail very quickly and there will be no point in them at all. After all, moisture that gets into this material reduces its characteristics down to zero.
• All roofing structures and its elements will be destroyed by microorganisms over time.
• In the winter season, icicles will certainly appear in the attic and a large number of ice, which will lead to stains on the ceilings of living rooms.
• Some roofing materials will begin to swell and typically fail much earlier than their useful life.

Surely, you do not want to encounter these problems, so, most likely, you have a question: how is high-quality ventilation of a soft roof created?

To ensure this, you should adhere to the following rules:

• An air gap should always be created between the layers of roofing pie being laid. This can be achieved with the help of small beams, the thickness of which is at least 5 centimeters. These elements are located between the insulation and the base
• Often, developers leave the bottom of the slopes open to provide additional air flow, but experienced roofers cover such areas with soffits. They prevent birds and rodents from taking up residence in your attic. And for additional hood Various aerators and ventilated ridges are used. By the way, we will talk about them below
• As mentioned earlier, the sheathing should have some gaps of 1-3 millimeters in order to eliminate the possibility of stagnation of air masses
• Height air gap created between the insulation and the base must be correctly calculated. In progress roofing works, the workers created for themselves some selection rules given value. If the slope degree is 10 degrees, and its length is only 5 meters, then a 5 cm air gap is quite enough. With the same angle, but a slightly much longer length - 25 meters, the layer will be twice as large

Roof ventilation from a soft roof can have either one or two circuits. Let me list you the layers of dual-circuit ventilation.

• Insulation boards
• Diffusion film
• Wind barrier
• First air gap
• Second gap for air access
• Roof covering

In addition to natural ventilation, you can always create forced ventilation.

Forced ventilation

This type may be needed only when natural ventilation does not cope with its functional task or there is no way to equip it.

To create an artificial circulation air mass you will need to install so-called aerators. This device works due to the difference in pressure between the room and the pipe.

Today you can meet them in hardware store absolutely different sizes and forms. When purchasing these parts, you should understand that the smaller they are, the large quantity required to complete the task.

Here's what you should know about roof aerators:

• If you plan to install several aerators, then there should be no less than 12 meters between them.
• For their device you should choose the most high points roof and distribute them evenly across its plane.
• When installing aerators on a new roof, the location of the pipe should be at the junction of the insulation boards.
• If you are carrying out roofing repairs and the problem was swelling of the coating, then install the aerator in this exact place.
• You should not make holes for pipes exactly to their diameter. Create it a little larger by about 1-2 centimeters.
• Fastening elements for aerators are anchor bolts or dowels
• The resulting joints are sealed using adhesive waterproofing products.

To monitor air humidity in the attic, I advise you to use special thermometers. They will be indicators of the operation of your natural ventilation, and if it malfunctions, you can install aerators.

Installation of an aerator in a building in use

If your roof is made of flexible tiles and natural ventilation does not fulfill its functional purposes, then you have to purchase auxiliary elements for ventilation - aerators. If you choose not to do this, then rest assured that you will soon have to change not only roofing material, but also the entire roofing system.

There is nothing complicated in the design of an aerator, judge for yourself.

1. First you need to choose a place where the aerator will be mounted. If the roof has problem areas, then it is best to install it there.
2. To do this, a hole is cut out, the diameter of which will be slightly larger than the pipe itself.
3. If during the installation of this element you discover that your insulation is wet, then it should be replaced with a new one.
4. Before as metal parts aerators will sink into the roofing pie, they should be treated with mastic, the same is done with the base.
5. The aerator elements must be securely placed on the roof plane. To do this, they are screwed on with self-tapping screws.
6. The lower part of the pipe is insulated.

If this process If you can’t do it yourself, don’t despair - call a specialist or take an experienced roofer as a partner.

Auxiliary roofing elements

In addition to aerators, the roofing sphere has several more parts in its arsenal that significantly increase the quality of natural ventilation.

Ventilated ridge for soft roofing

This element is installed at the very top of the roof. Its design is somewhat different from a regular skate. A ventilated ridge has walls with a number of holes. It is through them wet air and leaves the attic. The operating principle of a ventilated ridge is similar to an aerator; everything happens due to a pressure difference.

Wind strip for soft roof

The end strip for a soft roof is a mandatory component. The fact is that strong gusts of wind can easily tear the coating off the base and you will have to repair it. This element will also serve as a worthy addition to the completeness of your roof and give it a chic appearance. Therefore, if you are concerned not only with a well-made roof, but also with beauty, then this element is undoubtedly worth your attention.

As a conclusion, I would like to note that soft roof installation - perfect solution for covering utility or temporary buildings. For this, roofing felt or other rolled product is best suited. Bitumen-based materials have maximum waterproofing, therefore roofing system will serve its maximum life.

By the way, if you have the finances, then ask around at a hardware store for tiles with a self-adhesive side. This will greatly facilitate and speed up the installation process.
