Over the years of using metal tile roofs, it has established itself as a durable, reliable and affordable roofing material. It is more often used for gable roofs, since sheets of thin and light metal with extruded relief are perfect for DIY installation. The only weak point of such a roof is the corner between the slopes, which is unprotected from moisture and is blown through. To quickly and aesthetically eliminate this defect, you need to install a stacked metal ridge.

Reasons for installation

I call the junction between two roof slopes a ridge joint. No matter how ideally the installation of the roofing material is carried out, small cracks and gaps remain between the sheets. Not only does it look unaesthetic, but an unsealed ridge causes the following problems in the operation of a metal roof:

• Penetration of moisture into the cracks between sheets of metal tiles. Water seeps into any, even minor, gaps, penetrating under the roofing material and destroying wooden elements rafter system.
• Blowing cold air under the roof. An unsealed ridge is an abyss into which heated air from a heated house goes; this is a gap not only in the roof, but also in the budget, because in order to maintain optimal temperature more fuel and energy resources will be required.
• Ventilation problems. Installing a stacked ridge on a metal tile will help to establish effective ventilation of the attic or attic space. The air there will be fresh, without drafts.
• Noise. The air, entering under the sheets of metal tiles through the ridge, circulates and is divided into streams, due to which the roofing material is deformed and makes popping sounds.

Mounting the ridge does appearance metal roofing harmonious and complete, will preserve the healthy condition of the wood of the rafter system, increasing its service life.

Assortment of inlaid skates

If previously you had to think about how to equip external corner between the roof slopes, then now it’s enough to come to hardware store and choose a finished ridge in the color of the metal tile of the shape you like. Manufacturers offer the following options:

1. Semicircular models. Metal that is pressed into a semicircular shape. It is necessary to attach plugs to the end sides of a type-formed ridge of this shape to close the voids into which snow, water or wind can get. The most expensive of the entire range of skates.
2. Straight models. Made in the shape of a rectangle, it is used for hips, gables, and to decorate the ridge. Fastening a rectangular profile will cost less than a semicircular one, but such a connection will look simple.
3. Triangular models. They completely repeat the geometry of the angle between the slopes, so their installation does not involve the use of plugs. Most cheap way finish roofing work on a metal roof.
4. Decorative models. They differ from other types of skate in their purpose. Fastening decorative elements with narrow shelves does not solve problems with waterproofing the gap between the joints, but simply gives a neat look.

When choosing a metal ridge connection, you need to pay attention to the width of the shelves and the presence of edging. Models without a wrap are not rigid enough to remain level when secured with self-tapping screws. And narrow shelves, the width of which is less than 150-200 mm, are not able to effectively protect against the penetration of water and snow.

Selecting a seal

Professional roofers advise inspecting the condition of the ridge groove before starting work. If the installation of metal tiles was carried out correctly, then there should be no gaps thicker than 20 mm. Otherwise, a sealant must be used. The following types are suitable for this:

Even if the joint between the slopes seems smooth, insulating it with a sealant before you start attaching the ridge will never be superfluous, because the life of the roof and its safety depend on the tightness of the connections. interior decoration attics.

Installation sequence

In order for the skate to perform the functions assigned to it, you must follow the recommended installation technology. It’s difficult to do high-altitude work alone, so it’s better to have a couple of assistants. Installation must be performed in the correct order:

When working with metal tiles, you need to screw in self-tapping screws at the crest of its wave, use a rubber seal to isolate the holes from moisture or special self-tapping screws, the rubber head of which performs the same protective functions. When performing installation, do not screw the screws too often or rarely, find a middle ground so that the metal tile does not “whirl” due to an excess of fasteners and does not “slam” in windy weather if there is a shortage.

Installing metal additional elements on the ridge will protect the roof from moisture and save heat, however, during installation, do not forget about safety precautions when working at height.

Video instruction

The ridge is one of the constituent elements of the pitched roof of a building. This area is exposed to intense climatic factors and therefore must have a number of characteristics that ensure protection of the under-roof space. To do this, you should choose the right type of roof ridge and take into account the technology for its installation.

What is a roof ridge

A pitched roof consists of several planes, in the area of ​​closure of which a ridge is formed. On different types roofing design of this element may differ, but the ridge is always the highest point of the roof. The area of ​​closure of planes is most pronounced in gable roofs. In broken, hipped and other similar structures there is also a ridge.

The ridge is present on different types of roofs

The functions of this element are as follows:

• main purpose is to close the upper edges of the slope planes;
• ensuring free air circulation in the space under the roof;
• preventing the appearance of condensation, as a result of which the roof is subject to deformation and rotting;
• an aesthetic addition to the roof slopes for the finished appearance of the building.

The roof ridge has simple design, but prevents moisture from entering the space under the roof. This extends the life of the roof and ensures the integrity of all materials. roofing pie.

Roof ridge design

A roof ridge is a long element that is mounted on the joint area of ​​the roof covering. The part can be in the shape of an angle, a semicircle, or a figured element. Such a roof edge is mounted horizontally, but the sheets of roofing material should not be tightly connected under the ridge. This is necessary to create a ventilation gap that allows air to circulate.

A ventilation gap is required when installing a ridge

When constructing the element, a special seal is used that prevents the penetration of cold air, but ensures the removal of moisture. The ridge is attached to the rafter system using roofing screws with a sealing insert.

Calculation of the height of the ridge for the roof of a house

Various methods are used to calculate the height of the ridge, but the mathematical one is the most popular. In this case, the formula H=0.5×B×K is used. In this formula, H is the desired height of the roof ridge, B is the width of the building, K is the coefficient of dependence on the roof slope, which is selected from the table. Using these indicators, you can independently calculate the height of the ridge, but you can also use online calculators by entering the available data.

Table: coefficient value depending on the roof slope

The mathematical example of the calculation is optimal for pitched roofs, but the same principle is used to calculate the height of a flat pitched roof. All the necessary parameters are preliminarily determined depending on the type and design of the roof, which must be indicated in the project.

Elements for different types of roofs

Used to cover the roof various materials, differing in installation technology, characteristics, appearance. Depending on the type of material used, the ridge option is also selected, which allows you to properly arrange the roof.

When installing the ridge, seals are used

Semicircular ridge for metal tiles

To equip a metal tile roof, a semicircular ridge is used, which consists of a seal and a ridge strip that provides ventilation. The seal is placed between the roofing and the semicircular ridge, preventing dust and moisture from penetrating under the roof.

The sealing elements can be profiled, which are made of foamed polyethylene. Profile elements

have an optimal shape Universal seals

made of polyurethane film and protects well from dust without interfering with air circulation. They have a self-adhesive base and are easy to install. Universal seals are safe for human health and practical to use.

Universal tapes are simple and easy to use

Self-expanding seals are made from polyurethane foam impregnated with polymer. The elements serve to cover the upper edges of the roofing material and secure the slopes.

A semicircular ridge is attached to the seal, and for this purpose ridge screws are used. Plugs are installed at the ends to provide additional protection to the structure.

Profile for polycarbonate

Roofs from cellular polycarbonate often created for greenhouses, extensions, gazebos and other similar structures. The area where the planes meet also requires a ridge, which is a profile semicircular or corner element made of polymer material.

The profiles go well with additional materials

The ridge for polycarbonate is attached using thermal washers, equipped with sealing rubber bands. This eliminates the possibility of moisture and dust getting under the roof.

Element for hip roof

For a hip roof, a semicircular element with mounting holes is used. main feature ridge for such a design is that the length corner element less roof length. Skate for hip roof can be made of metal, which is optimal when covering the roof with metal tiles.

The semicircular ridge complements the hip roof well

The ends of the ridge hipped roof covered with special elements shaped like a semi-cone. The top element for the roof is made up of several elements. This creates a bar of the required length.

Roof ridge made of wood

The roof of a house can be made of wood, but it is extremely important to follow the construction technology, since wood does not withstand climatic influences well. In this case, the ridge is formed at the junction of two beams of the rafter system. The element may be a long round log, laid at the junction of the planes pitched roof.

Wooden covering is original and environmentally friendly, but it is important to properly arrange the roof

For the manufacture of tiles and ridges, larch, cedar, oak, and spruce wood are used. These materials are more resistant to humidity, temperature changes and other climatic factors.

Roof ridge made of flexible tiles

For roofs covered with soft tiles A ventilated ridge is convenient, providing air circulation under the roof. This eliminates condensation from the layers of the roofing pie and protects all structural elements from rotting. The skate is installed on the horizontal line connecting the slopes.

Skate for soft roof easy to install and no difference complex design

The element for a soft roof is a polymer corner with ventilation holes. The part is attached to the rafter system, and the tile elements are fixed on top. Thus, the roof is equipped with a ventilated ridge and has an aesthetic appearance.

Slate roof element

Slate roofing often equipped with galvanized steel skates. Such elements are affordable, easy to install and durable. If the roof is covered flat slate, then installation is as simple as possible and involves fastening galvanized corners with screws or nails. The skates have edges that are curved inward, which provides a ventilation hole.

The slate ridge can have a semicircular shape

When installing the corner, a ridge tape is used, which ensures maximum quality of the roof. The corner is fixed with an overlap onto the roofing sheets.

Important points when installing a ridge

Various materials serve as the basis for making a roof ridge. The most practical are copper products and galvanized steel corners. For corrugated roofing, a ridge with colored polymer coating. Depending on the type of roofing, the material of the corner is selected, which allows you to equip the roof with the highest quality.

Metal corners durable and easy to install

Materials and tools for work

Simple technology attaching a ridge to a roof made of corrugated sheets involves the use of accessible, but quality materials. To work you will need the following components:

• seal with self-adhesive side;
• metal ridge of optimal shape;
• thermal washers with sealing rubber bands, roofing screws;
• screwdriver, hammer, tape measure, building level, knife.

Fastening the corner

The process of fixing the corner does not require special skills, but when carrying out work on the roof, a safety belt must be used. Fastening begins from one of the ends of the roof in the direction opposite to the movement of the prevailing winds. The set of actions involves the following stages:

To equip your roof with a ventilated ridge, you should purchase finished corner with a special design that ensures air circulation. The part is attached to the corrugated sheet using the same technology as a regular corner.

Operation and finishing of a ridge on the roof of a house

When arranging a roof and installing a ridge, a sealant is often used, which is a polymer tape with a self-adhesive layer. This material eliminates consequences such as snow, dust or moisture getting under the outer roofing layer. You can buy the sealant in construction supply stores, and manufacturers produce various options such tapes.

Seals come in a variety of shapes, making choice easy

Correct construction of the ridge is the key to good protection of the roof structure from deformation and rotting. After graduation construction work the ridge can be decorated to complement the design of the building. To do this, use the following solutions:

How to repair horses with your own hands

The roof edge is exposed to winds and other climatic factors. Therefore, damage such as separation of ridge elements, deformation, and cracks often occurs. In such cases, repairs are necessary, which are carried out using a safety belt. Before work, you should assess the damage, prepare new ridge elements and fasteners. Next, manipulations are carried out on the roof, that is, the damaged parts and seal are removed, and new components of the ribs are fixed in their place. If necessary, the ridge is completely replaced.

The roof ridge device is the installation of the horizontal upper edge of the roof at the intersection of the slopes and all kinds of elements located on this edge. Let's take a closer look at the manufacture of the roof ridge, the correct calculation of its height, installation and ventilation of the space under the roof.

It is a horizontal rib at the very top of the roof, which is formed by the junction of the roof slopes.

Previously, after the construction of the roof of houses, the roofing of the ridge was made with materials based on asbestos cement. Roofing iron was rarely used.

Galvanized iron has become the most popular for making ridges. They use ready-made corners or make their own from galvanized steel, having a length of about 2 m.

The corner for the roof ridge can be made as follows: a sheet of galvanized steel cut to size is laid on the marked flat surface and tap before purchasing the profile the desired shape using a mallet (a metal hammer may damage the galvanized coating).

• width - from 2.4 to 3 cm;
• length - 200 cm.

The skate device must include the following elements:

• roof ridge;
• rafter leg;
• roofing timber;
• sheathing;
• cover sheet;
• nails;
• galvanized profile.

It must be remembered that the ridge elements should overlap each other by 10 cm, and the side of the corner used by 12-15 cm.

All nails, passing through the waves of the roofing of the house, must fall exactly into the sheathing. For convenience, an additional beam is often installed on the sheathing in the ridge area.

Previously, the gap between the roofing and the ridge was covered with mortar. Currently, this is mainly used polyurethane foam.

Making a skate with your own hands is a relatively simple procedure. All you need to do is to correctly follow the safety regulations when working at height.

Determining the height of the ridge and subsequent installation

Tools for installation: 1. Screwdriver; 2. Hammer; 3. Mallet; 4. Brush with soft bristles; 5. Roulette; 6. Long rail; 7. Marker; 8. Level; 9. Metal scissors; 10. Round nose pliers.

For self-made and you may need the following tools:

• screwdriver;
• electric screwdriver;
• hammer;
• mallet;
• long rail for straight lines;
• markers;
• metal scissors;
• hacksaw for metal;
• saw or jigsaw.

The height of the ridge is directly dependent on the angle of the slope, the frame and the material from which the roof covering is made.
After the roofing material has been secured, you can begin installing the ridge.

Ridge installation

Determination of height.

1. First, ridge tiles are installed along the edges of the roof slope. After this, the distance from the top to the inner edge of the tile from the narrowest end is measured. The bars are the main component of the top edge. They are called counter-lattice. They are connected to each other at minimum distance. This distance is also called the ridge aero element.
2. It is also necessary to correctly measure the distance between top part the beam holder installed in the fastening, and the bend point of the fastening line. Using nails, the top beam of the ridge is attached to the counter-lattice (to the central part).
3. Having mounted the fastenings on both sides of the ridge, a special mounting cord is pulled between them. If this is not available, then use a regular thick fishing line. The cord is required in order to properly lay and fasten the ridge run.
4. The ridge beam must be placed in fasteners and holders, then it is nailed with galvanized nails or stainless steel nails.

Note. The roof requires the mandatory presence of lightweight side tiles, which are designed to cover the ridge run after completion of the above work.

In order to avoid the penetration of moisture, condensation or steam into the gap under the ridge, it is necessary to properly hydro- and thermally insulate the roof of the house.

When installing a ridge on a standard gable roof, all seams and joints formed during laying of roofing materials must be completely hidden behind the ridge girder structure.

Do not forget that a roof equipped with a ridge must be equipped with a ventilation compartment. Otherwise, constant formation of condensation will occur, regardless of the presence of a waterproofing layer.

Ventilation ducts are sold in finished form, but you can make them yourself. They can be installed using special fasteners or glue.

Advice: the ventilation box should only be glued to dry and cleaned roof elements of the house. It is not recommended to carry out work in cold or too hot weather.

After completing the work on calculating the height of the ridge and completing all related processes, the direct installation of the purlin itself is carried out. One of the best materials for the manufacture of purlins, special ridge tiles are considered, which also serve as decoration for the roof of the house.

The installation of such tiles begins on the leeward side. This is done in order to avoid precipitation and wind blowing under the joints of the roofing material. First, the clamps are installed, onto which the tiles are then attached, nailed or screwed with self-tapping screws.

How to properly ventilate a roof ridge?

The ridge is designed not only to prevent moisture from penetrating into the gaps between the covering materials of the slopes, but also to create ventilation under the roof.

The importance of ventilation of the space under the roof of a house becomes most relevant when installing a roof with insulation.

A ridge roof ventilation system can be made as follows:

1. After the construction of the rafter system is completed, fastenings are made across the legs of these same rafters waterproofing film. Laying the upper strips of film on the lower ones must be done with an overlap of at least 15 cm in size. All seams are taped with a special connecting tape.
2. Along rafter legs the counter-lattice is stuffed. A sheathing is mounted across it on top.
3. The selected material is placed on the sheathing roofing(slate, metal tiles, ondulin, etc.).

The stretched film performs the functions of protecting the rafter system from the formation of reverse side roofing condensation and possible water leaks through cracks. The film also slows down the process of rotting of wood elements and prevents the appearance of rust on metal elements.

If there is no ventilation of the space between the roofing material and the film, the moisture penetrating there will not dry out, which in turn will lead to rotting or rusting of the sheathing and counter-batten elements.

Creating an insulated roof involves using a layer of insulation under a layer of waterproofing. Thermal insulation materials mainly consist of hygroscopic components, for example, basalt fiber. In the absence of good ventilation, moisture accumulates in them, which significantly reduces the heat-shielding characteristics and leads to rotting of the rafters, between which the insulating layer is located.

The ventilation space, preventing the above problems, can be done as follows: equip bottom part cornice hems ventilation gaps or grilles to allow air penetration.

In addition, before final fastening of the ridge, it is necessary to create sufficient air space between the waterproofing and the main roof covering and make a hole for the outlet of humidified air between the slopes.

Air escape through the ridge may occur different ways. This depends on the roofing material used and may require installation additional accessories ventilation.

At the joints of roof slopes, careful sealing and protection of the under-roof space from the formation of moisture and the “walking” of the wind is necessary. To do this, at the final stage of installation, a roof ridge is installed on the roof.

In most cases, it is made of steel coated with polyester, but a galvanized roof ridge is also available to cover the joint of an andulin roof.

The metal roofing ridge can be made in several options:

• Flat roofing ridge (simple)
• Figured horse
• Semicircular ridge

The coating options for this element can be several variations: zinc, polyester and textured coating.

As a rule, ridges are made to order, but there are still popular sizes of roofing ridges:

• 110*110 (120 gr.)
• 110*110 (90 gr.)
• 193*193 (90 gr.)
• 193*193 (120 gr.)
• 141*141 (120 gr.)
• 141*141 (90 gr.)

The average length of one element is 2 meters, however, when manufactured on the LGS-3000 machine, the skate can reach a length of 3 meters.

Advice! When ordering a roof ridge, you must indicate the presence of a rolling seam of at least 15 mm.

The production of roofing ridges can be organized directly on the territory of the exhibition hall, since only a sheet bending machine is required for its production. Therefore, you can buy a roofing ridge, along with all the basic materials in one place.

The main feature of installing a roof ridge is maintaining the length of the overlap between constituent elements. For metal skates the overlap is 10 - 15 centimeters.

You can easily calculate what is needed for this roofing element. You need to calculate the total length of the joint and divide by the length of the ridge minus the overlap.
For example,
element length 2 meters,
joint length 5 meters.
10/1.9 ​​= 5.26, i.e. 6 items.

A roof ridge is a structure that covers the gap created at the highest point after covering the roof with roofing material.

As a rule, the roof ridge and the main roof covering are made of the same material. It can be any type of tile, slate, metallic profile or galvanized steel.

But, in its form, the device can be various forms– semicircular or angular, relief or figured.

The main purpose of the roof ridge is to ensure air exchange in the under-roof space. Increase service life and protect rafter system roofs can be done by removing excess moisture. If the ridge installation was done correctly, then you don’t have to worry about condensation accumulation and roof leaks.

In order for the job to be done well, it is necessary to choose the right material, as well as additional elements. Correctly selected additional parts and material can facilitate installation work, as well as normalize humidity levels and prevent roof leaks.

The roof ridge is a guarantee that condensation will not accumulate in the under-roof space. The roof covering will also be protected from wind and precipitation and high reliability of the entire roof will be ensured.

Types of roof ridges

This roof element covers the gap that is created at the highest point of the roof when roofing material is laid on the roof slopes.

The roof ridge can be made of the same material as the roofing, for example, slate, metal profiles, galvanized steel and different types tiles. This element is also called a ridge strip.

This part comes in several configurations:

• Angular;

• Semicircular;

• Conical;

• Rebrova;

• Figured;

• Embossed.

Calculate the height of the ridge using a geometric formula

It is clear that the height of the ridge directly affects the angle of the roof slope. If the ridge is very low, as is the roof slope, then good snow cover will become real threat for the safety of the home and the people living in it.

And, conversely, if the ridge is too high, with a large coverage area, they make roof structure defenseless against strong winds.

You should also understand that roofs that are too low or high do not have an attractive appearance, and this is important for a new home.

In our country, with certain climatic conditions, the most optimal size The angle of inclination is considered to be from thirty-five to forty-five degrees.

Ridge height gable roof calculated using simple geometric formulas. To do this, the height of the ridge should be taken as the leg of a right triangle, where the second leg will be the full length of the building, cut in half, that is, into two. Then the length of the slope is taken as the hypotenuse.

formula for calculating the height of the ridge of a gable roof

Applying the geometric formula school course, which helps to find the length of one of the legs in right triangle, it turns out that to calculate the height of the ridge, you need to multiply the length of the second leg by the tangent of the angle located at the base of the triangle.

For clarity, an example should be given - if the width of the house is six meters, and the slope of the roof is forty degrees, the tangent of which equals zero point eighty-three hundredths, then we get the height of the ridge equal to two point fourty-nine hundredths. (0.83*6/2=2.49).

Installing a ridge is a rather complex and labor-intensive task that should not be done alone. Its fastening begins from the edges, and before that you should stretch a thin cord, which allows you to install the roof ridge strictly in a horizontal line.

As connecting elements They use special self-tapping screws with gaskets that do not allow moisture to penetrate, and therefore be subject to corrosion, at their connection points.

Features of roof ridge installation

When installing the ridge, the following nuances must be taken into account:

1. The roofing material on the roof ridge should not create a tight connection, since in this case the access of air to the under-roof space will be blocked.
2. The ridge is installed on final stage roofing works. At the same time, ventilation building materials are laid, which will protect the under-roof space from birds and all kinds of insects entering the attic. This material will also prevent precipitation from getting on the boards or ridge beams. Mineral or glass wool, a special sealant and other materials can be used as a protective layer.
3. During installation, you also need to ensure that the space under the ridge strip is not overly filled. Otherwise natural ventilation will be disrupted or eliminated. This can happen if the ridge space is sealed with a sealed material or foamed with polyurethane foam. This problem usually appears when installing mansard-type roofs. For this reason, this element must be ventilated.
4. It is best to install this element together. In this case, you must have a ladder. To install the ridge on the roof, you only need a screwdriver and self-tapping screws. Installation work They are quite dangerous and labor-intensive, so it is very important to follow all safety measures.
5. When building a roof, you need to know the height of the future ridge. This is necessary in order to accurately calculate the amount of building material for its manufacture. It should be noted that the height of the ridge depends on the angle of the roof. When calculating the height of the ridge, the rules of geometry are used.

Installing a ridge on the roof

The ridge is installed at the final stage of roofing work; be sure to include a ventilation gasket, which serves as protection against precipitation, as well as birds and insects from entering the attic.

Therefore, in this case, you should not use polyurethane foam, through which natural ventilation will not occur. The same goes for sealed materials, used for thermal insulation of roofs.

Once installed, you can begin installing the ridge. Today manufacturers of construction and finishing materials offer ready-made roof ridges.

As a rule, they are standard; have a length equal to two meters and wide shelves - approximately two hundred centimeters.

The installation of a ridge consists of several stages:

1. First of all, at least two elements of special ridge tiles are installed. It should rest on the roof slopes on both sides. Next, measure the distance between the inner edge of the narrower end of the special tile and its upper edge. The latter consists of counter-lattice bars connected to each other at the shortest distance. It is sometimes called a ridge aero element.
2. Then you need to measure the distance between the top ridge beam, inserted into the holder mount and the bend point of the mount line. Next, a holder or mount is made. After this, the top beam is nailed to the central part of the counter-lattice using nails.
3. Before fixing this element, it is necessary to tighten the thin cord. It will be used to adjust the horizontal installation of the remaining parts of the ridge. To secure the ridge, you should use self-tapping screws with special washers that will prevent moisture from entering the joints. You must first make holes in the slate parts of the ridge. Then the slate will remain intact when nails are driven into it.

Use of additional components

When installing the skate, you will need its components. They increase the functionality of the roof ridge and also expand its purpose.

The main components include:

• Lightning rod holder;

• Ventilation tape;

• Ventilation ridge tiles;

• Other aeroelements.

When installing components, the following technical accessories are used:

• Semicircular skates, mounted at the junction of roof slopes;

• Skates rectangular shape , used in the construction of pitched roofs covered with metal tiles. They have attractive appearance and have high protective properties;

• Plugs. Used during installation additional elements roofs having a semicircular shape. They are used to close the joints of the slopes;

• Narrow skates. Made from metal tiles. They are decorative elements;

• Snow holder. It is one of the most important ridge elements. It prevents the snow mass from sliding and also reduces the snow load. This element must be firmly fixed as it must withstand a lot of weight. The snow holder is made from various materials;

• Wind bar. This accessory closes roofing sheets from the end side. It provides protection from wind, rain and other precipitation;

• Cornice. Is the most important detail for the cornice board. Performs a protective function. It is mounted under hydro- and thermal insulation;

• groove– a component that covers the joints of the roof slopes;

• Universal gasket. It is a special coating that protects the roof structure from excess moisture and the effects of other negative factors environment;

• Connection to the wall. This structural element closes gaps at the joints of slopes, and also protects the walls of the building from the effects of precipitation;

• Self-tapping screws. Used to secure ridges to roofing material.

It should be noted that additional ridge parts and roofing must be made of the same material. They must also have the same color.
