From time immemorial, dacha and suburban construction has attracted not only the opportunity to spend a good rest away from the bustle of the city, but also the independent arrangement of one's housing. Of course, at some points during the construction of a cottage and a personal plot, certain difficulties arise that must be solved with the help of craftsmen, however, if desired and with due patience, you can build some elements of the house structure with your own hands. Having finished with the foundation and walls, each owner is faced with questions about how to properly equip the roofing system.
In this article we will tell you how to make a roof ridge with your own hands, consider options for a roof made of slate, corrugated board, metal tiles.
Starting to study the procedure for erecting these elements, you should understand what is the difference between such concepts as "roof ridge" and "roof ridge". The first is formed at the intersection of two roof slopes, and the second is a separate element, which is selected depending on the type of roofing material.
The main purpose of the roof ridge is to provide ventilation and remove moisture that forms on the inner sides of the slopes. The functioning of this element is achieved by laying roofing materials in such a way that there is a small gap between them at the upper junction point.
To date, the installation of a skate can be done both through ready-made kits, and with your own hands, having prepared the necessary materials. In the first case, the owner saves himself from taking measurements and preparing the metal for installation. If everything is selected for you, it remains only to choose the shape, which is represented by figured, embossed, conical, semicircular and other types. Self-manufacturing of a skate involves cutting metal on your own and making an even bend, which in most cases is difficult to do at home.
There are many ready-made solutions for both metal roofs and other roofing materials. As a rule, manufacturers of a particular product offer to use their material, prepared specifically for their coating. It should be said that the purchase of ready-made ridge elements is the optimal solution, ensuring the exact fit of each detail and which will help create an excellent aesthetic appearance. In this case, the owner is only required to lift the cut blanks onto the roof and, in accordance with the instructions, perform their installation.
The construction of the roof ridge should be started only after the completion of all roofing work. Its fixation is carried out on the prepared coating, which requires, in the version of the insulated roof, insulation to be performed before the process of placing the ridge.
If you are going to equip a skate, first of all, you should figure out what this element is and how to install it correctly. The roof ridge includes the following parts:
- timber - provides retention of the outer coating that protects against the harmful effects of environmental factors;
- wooden or metal racks.
As mentioned above, the ridge provides roof ventilation. However, we must not forget the fact that small gaps between this element and the roof slopes can cause birds, rodents and insects to appear in the attic of the house, so protection against them should be provided.
To solve this problem, it is most rational to use special grids with small cells. A sufficiently strong material, for example, aluminum, should be chosen as the basis for it. it has sufficient strength and flexibility.
Having finished with the arrangement of the ridge, one should not forget about the plugs that are installed in the end part of the structure. Their fastening is carried out by means of self-tapping open openings between the slopes.
The modern assortment of goods in stores in this area is large. In some versions, the ridge is placed on racks made of timber, located on ceilings or screeds. In another case, it is formed by sheathing boards at a certain slope, which are placed close to each other. To date, there are the following types of skate:
- Ridge bar (profile skate). Its main purpose is to connect two roof slopes and protect them from moisture and dirt getting under them. The abundance of colors allows you to choose the ridge to match the roof and ensure a single harmony of the overall color. During installation work, do not forget about the gasket of a special seal.
- Mortise and crossed. These types of skates are often used in the construction of a hip rafter system. The fixation of the elements is carried out by inserting into the roof slopes or by installing intersections.
- Semicircular. Not much different from the first type, but has a more aesthetic appearance. In addition, special plugs are installed from the ends to prevent the ingress of debris and precipitation.
In the course of work, it must be taken into account that ventilation of the space under the roofing is achieved due to the gap left. Having finished with the facing of the slopes, you should start laying the ventilation material, which provides reliable protection for the support beam of the future ridge from the penetration of atmospheric precipitation.
At the same time, the intermediate layer also solves another important problem - it excludes the penetration of insects and birds into the attic. As a basis for this element, it is more expedient to use special seals, mineral glass wool, etc.
When installing the ridge, the use of mounting foam and sealants is prohibited, since they impede the circulation of air under the roof.
After weighing all the features of the material and deciding on its choice, you should purchase the required amount of ridge, as well as its components and fasteners. As a rule, the composition of the ridge element includes a ventilation partition and a tape, fasteners for a lightning rod and a sealant.
To avoid dimensional discrepancies when joining, as well as to ensure high-quality connections, it is necessary to purchase all roofing materials from one supplier.
To successfully complete the task and reduce preparation time, it will be necessary to assemble the required tools and fixtures in advance, namely:
- sliding construction ladder;
- building level and tape measure;
- screwdriver or drill with a set of drills and bits for working with roofing screws;
- kapron cord;
- metal scissors or grinder.
The use of an electric tool greatly simplifies any installation, however, in the absence of appropriate equipment, it is easy to find an alternative to it from the tool available in everyday life.
Height calculation
Starting the arrangement of the roof, a necessary measure is the calculation of the height of the ridge. This will allow you to make all subsequent calculations of consumables that will be required during the construction of rafters and roofs. This indicator is determined using geometric parameters and is calculated based on the angle of inclination of the facing roofing material and its type. So, in the variant made of reed or another type of soft roof, such materials are laid with an inclination in the range from 12 to 85 °. However, slate and other materials are fixed with a slope of 15–60°.
At the same time, the overall aesthetics of the building should also be taken into account - the height of the roof should be optimally coordinated with the proportions of the house. Too high or excessively flat roof can spoil the whole look. For our strip, it is most rational to use a roofing material slope of 30–45 °, otherwise the cladding will be subject to increased wind or snow loads.
To carry out the necessary calculations, you will need to turn to geometry and calculate the values using a simple formula. So, you need to take a right triangle and calculate the length of the leg, which is equal to the length of its second counterpart, multiplied by the tangent of the base angle. Having a house with a width of 6 m and an angle of inclination of 40 °, we find the values of the tangent from the school tables - in this case it will be 0.83. As a result, we obtain the formula: 6/2 × 0.83 = 2.49 m - the optimal height of the ridge element.
The construction of the ridge is started after the completion of the procedure for fixing the roof on the slopes. Decorative components are delivered to the place of placement by means of a winch mechanism or a rope. To fix the ridge element, it is necessary to install a beam with a cross section of at least 80 × 100 mm from the outside between the slopes. Further, to each of its sides, crate bars are fastened and a ridge bar is installed.
To simplify the subsequent process of laying parts, it will not be superfluous to attach special brackets to the central support beam and place navigation bridges on them. In addition, for the tightest fit of the roofing material, it is most rational to use a ridge beam with a rounded edge.
Protection against decay, development of mold and fungal formations is an integral process during installation, which provides for upholstery of the ridge beam along its entire length with roofing material or a special sealant. This practice can significantly extend the life of not only the ridge, but the entire roofing system.
In the option of making a roof from slate, it is most rational to select a ridge from a similar material - asbestos cement, or use galvanization.
Fastening is carried out directly to the ridge beam by means of slate nails or self-tapping screws, so that the overlapping of parts comes from the pediment of the house.
For example, let's take the placement of a ridge element on a metal roof. For high-quality performance of work to ensure reliable functioning, it is carried out in the following sequence:
- make sure that the ridge axis is even - the place where the edges of the slopes meet (permissible discrepancies - up to 2-3 cm);
- when installing additional roofing parts, it is worth remembering the need to lay a small layer of heat-insulating material in the ridge grooves;
- lay the first and last ridge element on the prepared beam flush with the outer edges of the roofing (it is more rational to carry out all roofing work with a partner, who will significantly speed up the entire installation process);
- pull a nylon cord between them;
- fix the composite ridge elements with self-tapping screws (the screwing pitch should be moderate, about 40–50 cm).
Ridge elements should be chosen with a shelf width of 15 cm or more, since parts with smaller edges will not be able to reliably protect your attic space in the winter from snow.
In conclusion, I would like to note that the process of installing a ridge on an equipped roof is not as complicated as it seems at first glance. Taking into account the fact that all work is carried out at a significant height, then, having no installation experience in such conditions, it is best to seek help from specialists.

In the provided video, you can learn about the intricacies of mounting the roof ridge:
Scheme
The diagrams show the intricacies of mounting the roof ridge:
The device of the roof ridge is the installation of a horizontal upper edge of the roof at the intersection of the slopes and all kinds of elements located on this edge. Let us consider in more detail the manufacture of the roof ridge, the correct calculation of its height, the 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 ridge was covered with materials based on asbestos cement. Roofing iron was rarely used.
The most popular for the manufacture of the skate was galvanized iron. They use ready-made or make their own corners of galvanized steel, having a length of about 2 m.
The corner for the roof ridge can be made as follows: a cut-to-size sheet of galvanized steel is laid on a marked flat surface and tapped until the profile acquires the desired shape using a mallet (a metal hammer can break the galvanized coating).
- width - from 2.4 to 3 cm;
- length - 200 cm.
The skate device must include the following elements:
- roofing ridge;
- rafter leg;
- roofing timber;
- crate;
- cover sheet;
- nails;
- galvanized profile.
It must be remembered that the elements of the ridge 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 crate. For convenience, an additional timber is often mounted on the crate in the area of \u200b\u200bthe ridge.
Previously, the gap between the roofing and the ridge was covered with mortar. Currently, mounting foam is mainly used for this.
Making a skate with your own hands is a relatively simple procedure. All you have to do is follow the safety regulations when working at height.
Determining the height of the ridge and subsequent installation
Mounting tools: 1. Screwdriver; 2. Hammer; 3. Mallet; 4. Brush with soft bristles; 5. Roulette; 6. Long rail; 7. Marker; 8. Level; 9. Scissors for metal; 10. Round nose pliers.
For self-manufacturing and you may need the following tools:
- screwdriver;
- electric screwdriver;
- a 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 roofing is made.
After the roofing material has been fastened, the ridge installation can begin.
Installation of the skate
Determination of height.
- First, ridge tiles are installed along the edges of the roof slope. After that, the distance is measured from the upper to the inner edge of the tile from the narrowest end. The bars are the main component of the top edge. They are called a counter-lattice. They are connected to each other at a minimum distance. This distance is also called the ridge air element.
- It is also necessary to correctly measure the distance between the top of the timber holder installed in the mount and the bend of the mount line. Using nails, the upper beam of the ridge is fastened to the counter-lattice (to the central part).
- Having mounted fasteners on both sides of the ridge, a special mounting cord is pulled between them. If this is not available, then use the usual thick fishing line. The cord is required in order to properly lay and fasten the skate run.
- The ridge beam must be placed in fasteners and holders, then it is nailed with galvanized or stainless steel nails.
Note. When roofing, the mandatory presence of lightweight side tiles is required, which is designed to cover the run of the ridge after the completion of the above work.
In order to avoid the penetration of moisture, condensate or steam into the gap under the ridge, it is necessary to correctly make the hydro and thermal insulation of the roof of the house.
When installing a ridge on a standard gable roof, all seams and joints formed during the laying of roofing materials must be completely hidden behind the design of the ridge run.
Do not forget that the roof, equipped with a ridge, must be equipped with a ventilation compartment. Otherwise, constant condensation will occur, regardless of the presence of a waterproofing layer.
Ventilation ducts are sold ready-made, but you can make them yourself. They can be installed using special fasteners or glue.
Tip: the ventilation box should only be glued to dry and cleaned elements of the roof of the house. It is not recommended to work in cold or very hot weather.
After completing the work on calculating the height of the ridge and performing all related processes, the installation of the run itself is carried out directly. One of the best materials for making a run is considered to be a special ridge tile, which also serves as a decoration for the roof of a house.
The device of such a tile starts from the leeward side. This is done in order to avoid precipitation and wind blowing under the joints of the roofing material. At the beginning, the clamps are mounted, on which the tiles are then attached, nailed or screwed with self-tapping screws.
How to properly ventilate the roof ridge?
The ridge is designed not only to prevent the penetration of moisture into the gaps between the roofing materials of the slopes, but also to create ventilation under the roof.
The importance of ventilation of the space under the roof of the house becomes most relevant when equipping the roof with insulation.
The roof ridge ventilation system can be made as follows:
- After the completion of the construction of the rafter system across the legs of these same rafters, the waterproofing film is fastened. Laying the upper strips of the film on the lower ones must be done with an overlap of at least 15 cm in size. All seams are glued with a special connecting tape.
- A counter-lattice is stuffed along the rafter legs. On top of it, a crate is mounted across.
- The selected roofing (slate, metal tile, ondulin, etc.) is laid on the crate.
The stretched film performs the functions of protecting the truss system from condensate formed on the reverse side of the roofing and possible water leaks through the cracks. Also, the film slows down the process of decay of wood elements and prevents the appearance of rust on metal elements.
If the space between the roofing material and the film is not ventilated, moisture penetrating there will not dry out, which in turn will lead to rotting or rusting of the elements of the batten and counter battens.
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 insulation layer is located.
A ventilation space that prevents the above problems can be made as follows: equip the lower part of the cornice filing with ventilation gaps or gratings to allow air to enter.
In addition, before the final fixing of the ridge, it is necessary to create sufficient air space between the waterproofing and the main roofing and make a hole for the exit of humidified air between the slopes.
The exit of air through the ridge can occur in various ways. This depends on the roofing material used and may require the installation of additional ventilation devices.
Since rigid roofing materials are used on the roof of the house, it is necessary to solve the problem of sealing the joints. When any kind of composition is formed, a small gap appears, which must be covered with high quality so that water does not penetrate inside the house. Since the roofing material is not a single coating, but connected to a piece, special roof ridges are produced for reliable joining. They are made in such a way that reliable protection against water penetration into the roof is provided. The article will tell you how to choose the right material for your roof and make accurate calculations.
The roof ridge is designed to seal roofing materials
Roof ridge
The ridge of the roof of the house is a useful element needed to create the top of the roof. It unites the roofing material and completes the entire "composition".
The roof ridge is designed for several main functions:
Water protection after rain or snow melt.
Creating the right gap for ventilation spaces under the roof - so that the coating is dried after rain.
These two problems can be solved at once if you correctly approach the choice of material. Particular attention should be paid to the shape of the skate.
Varieties of skates
Since there is a wide variety of roofing and installation methods on sale, it is obvious that skate models also differ.
For sale are the following varieties roof ridges:
Semicircular. This species has no ribs. After installation on the roof, an air cushion is formed from the inside of the dome, which provides high-quality ventilation of the space under the roof. The ends are equipped with plugs, which create a finished look, and moisture is also prevented from entering through the cut of the ridge.
Straight- this is the simplest variety in which you do not need to install end caps. The ridge is suitable for different types of roof coverings.
Narrow. This skate plays the role of not only protection. It is often purchased as a decorative element that can be placed on an arbor, the roof of a private house, and similar structures.
Curly or curved. This is the most difficult type of skate. A peculiar profile provides an increase in ventilation properties.
It is important to know that in order to connect straight skates, it is necessary to use T or U-shaped elements, with the help of which they achieve strength and tightness of transitions.
All types of skates have only the two tasks described above, and the difference between them is exclusively in the mounting methods, which are due to differences in shapes.
The main elements of the skate
The roof ridge is a system of several parts. The composition may include waterproofing, mounting bars, or sealing parts.
The number of components depends from several factors:
Roof dimensions where the equipment will be installed.
Absence or presence ventilation system under roof space.
Myself roofing material, as well as design features.
The main element (in addition to the body), which is installed on all skates, is a waterproofing layer that protects the roof from water ingress. If the house is located in a windy area, then manufacturers install sealing elements on the material that will prevent wind from entering the under-roof space.
Details that will help solve the problem of sealing roof joints
On our website you can find contacts of construction companies that offer services roof design and repair. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".
Skate length calculation
In order to correctly choose the length of the ridge on the roof, it is necessary to determine the amount of the additional element as well as all the components - the waterproofing system, sealing materials, fasteners. The calculation basis is a building plan that specifies the entire project length of the story, as well as the materials that will be used.
It is important to understand that all the data for the calculation is an individual project, which depends on the recommendations of the supplier after studying the specific roof. The calculation of materials is very simple - you need to build on the length of the entire roof, the number of ridge strips m 5 cm overlap (this nuance is required).
Much more problems arise with the organization of substrates - ridge bars. They are necessary for the correct and even fastening of the planks. When a stable system is ready for installation, the roofing material must be accurately selected in order to then match the underlays to the specific profile dimensions.
The problem may arise due to the varieties of the skate. It is also problematic to determine some general system for placing support bars. The fact is that the type of fastening and sealing of elements requires an individual approach, therefore, in order to accurately calculate all the necessary nuances, it is advisable to mount it on a trial strip. Thus, it will be possible to make some changes or adjustments to the substrate. It is according to this scheme that professionals in the installation of roofs and skates work.
In order for the roofing ridge to be installed without defects, it is necessary to correctly choose a construction company for the installation of equipment.
Skate installation steps
The ridge should be installed at the moment when the roofing is completely placed and fixed on the roof. The last row should end in such a way that the ventilation gap between the slopes is not very large. A skate is needed to cover it.
Installation of the skate consists of the following stages of work:
First of all, it is made installation of waterproofing material to prevent moisture from getting inside.
Distance between ends removed with glass wool. Thus, it will be possible to avoid snow "blockages" after precipitation. It is not necessary to use glass wool. There are also other options, but they are not as resistant to decay, and also exceed the price of the above material. If someone is worried about the fact that cotton wool is very prickly after it hits open areas of the body, then you can forget about this nuance, since modern cotton wool is made using new technologies and manufacturers have managed to get rid of "pricklyness". It is important to note that there is no need to stuff the end space very tightly, as there is a risk of damaging the ventilation.
Glass wool will help to remove the distance between the ends
If there is a possibility of snow clogging, then a sealant is required. The most effective, but at the same time simple option is the laying of roofing material. Part of the strip clings to the roof, and the second to the beam, which sets the height of the structure. Having performed these simple actions, it will be possible to create additional protection against the penetration of precipitation into the roof. This issue is especially relevant for residents of regions where blizzards often occur - snow will wash away even into the smallest cracks.
The seal will create protection against the penetration of snow into the roof
Next on the roof is located directly on the ridge itself. For installation, special roofing screws are used, which have rubberized gaskets, as well as a layer of protection. It is strictly forbidden to use simple nails, as they will make holes in the surface, but will not seal them. As a result, a weak leak is formed, which will soon “grow” and turn into a full-fledged hole. Of course, in this case, you will have to spend additional money to eliminate the defect. When the first plank is securely fastened to the roof, it will be necessary to stretch a cord from it (along the line of the entire installation), which allows you to monitor the straightness of the installation of the remaining parts.
Remaining corners are in place with an overlap of 5 centimeters. It is important to observe the direction of installation of the skates - from left to right. But there is a case of reverse installation - the choice should be made depending on the direction of the wind that rages in the region. The situation is individual, and therefore in each case this issue has to be dealt with in different ways.
When all the ridge bars are in place, you can take care of installation of end elements if they are available. They are also designed to provide better protection from snow and rain.

Conclusion
Summing up the information, we can conclude that the installation of a roof ridge is complicated by a variety of roof covering materials, as well as a wide choice of shapes of the ridges themselves. Therefore, it is so important to choose a reliable construction company for the installation of equipment that works in accordance with the requirements of GOST SNiP, as well as the regulatory documents of the house itself. When drawing up an estimate, a quality firm must also issue an accurate and fixed amount for the work.
Over the years of using metal 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 an extruded relief are great for do-it-yourself installation. The only weak point of such a roof is the angle between the slopes, unprotected from moisture and blown. In order to quickly and aesthetically eliminate this defect, the installation of a type-setting metal ridge is required.
Reasons for installation
The junction between two roof slopes is called a ridge joint. No matter how ideally the installation of the roofing material is performed, small gaps and gaps remain between the sheets. Not only does it look unaesthetic, an unsealed ridge causes the following problems in the operation of a metal roof:
- Penetration of moisture into the gaps between the sheets of metal. Water seeps into any, even minor gaps, penetrating under the roofing material and destroying the wooden elements of the truss system.
- Blowing cold air under the roof. An unsealed ridge is an abyss into which heated air escapes from a heated house, this is a gap not only in the roof, but also in the budget, because more fuel and energy will be required to maintain the optimum temperature.
- Ventilation problems. Mounting a stacked ridge on a metal tile will help establish effective ventilation of an attic or attic space. The air there will be fresh, without drafts.
- Noise. The air, getting 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.
The installation of the ridge makes the appearance of the metal tile roof harmonious and complete, it will preserve the healthy state of the timber of the truss system, increasing its service life.
Assortment of skates
If earlier you had to think about how to equip the outer corner between the slopes of the roof, now it’s enough to come to a hardware store and pick up a finished ridge in the color of the metal tile of the shape you like. Manufacturers offer the following options:
- semicircular patterns. A metal that is molded into a semi-circular shape. From the end sides, it is necessary to attach plugs to a type-setting ridge of this shape in order to close the voids into which snow, water or wind can get. The most expensive of the entire range of skates.
- direct models. Made in the shape of a rectangle, it is used for hip, gable, to decorate the ridge. Fastening a rectangular profile will cost less than a semicircular one, but such a connection will look plain.
- triangular patterns. They completely repeat the geometry of the angle between the slopes, so their installation does not involve the use of plugs. The cheapest way to finish roofing work on a metal roof.
- decorative patterns. They differ from other types of skate in their purpose. Fastening decorative elements with narrow shelves does not solve the 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 a rim. Models without rims do not have enough rigidity to remain flat when fastened 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.
Seal selection
Professional roofers advise to inspect the condition of the ridge groove before starting work. If the installation of the metal tile was carried out correctly, then it should not have 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 to be even, its isolation with a sealant before starting to fasten the ridge will never be superfluous, because the lifetime of the roof and the safety of the interior decoration of the attic depend on the tightness of the joints.
Installation sequence
In order for the skate to perform the functions assigned to it, it is necessary to follow the recommended installation technology. High-altitude work is difficult to do alone, so it is better to get a couple of assistants. Installation must be carried out in the correct order:
When working with a metal tile, it is necessary to screw in the screws on 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 in the screws too often or rarely, find a middle ground so that the metal tile does not “excite” from an excess of fasteners and does not “clap” in windy weather with a shortage.
Mounting metal additional elements on the ridge will protect the roof from moisture ingress, save heat, however, during installation, do not forget about safety when working at height.

The construction of a private house is completed with the construction of a roof. This is a particularly important stage, since the reliability of the structure depends on the competent implementation of this process. The construction process itself can be conditionally divided into several stages, from the installation of the Mauerlat to the laying of the roofing.
When installing roofing material on slopes, gaps are usually formed at the point of their convergence in the uppermost part of the roof. Therefore, an element is needed that, on the one hand, will protect the under-roof space from the penetration of precipitation and melt water, and on the other hand, will provide roof ventilation. This is the so-called ridge on the roof (photo below).
This element is defined as follows. The ridge of the roof of the house is the upper edge, located horizontally at the junction of the slopes. It also includes those associated with this rib. Thus, this is a prefabricated structure, consisting of a combination of several fragments. Installing a ridge on a roof requires a little theoretical training and basic building skills, that is, in fact, everyone can handle this task.
Types of ridge construction
The ridge on the roof is formed by closing the planes of the slopes. It has two versions and depends on.
- A beam, which is installed on vertical racks, based on puffs or ceiling beams, or fixed on the gables. It serves as a support for the top of the rafters.
- Run (basis of the ridge), laid at the top of rigid triangular trusses set one after another from rafter legs connected in pairs, which are interconnected by jumpers. The role of a run can be a log of a roof ridge having a wide section or two boards 5 cm thick sewn at an angle.
From all this it follows that, first of all, we are dealing with a component of a gable roof. However, it can also be found in designs that have a more complex configuration. For example, or, in which it is displaced.
Relatively recently, asbestos cement was used to decorate the ridge, but today manufacturers more often offer a galvanized roof ridge. The dimensions of galvanized are usually standard: their length is approximately two meters, and the width of the shelves is 25-30 cm.
According to the installation site, there are three main options for the skate:
- Strips of sealant or special ventilation tapes are attached to the edge of the profiled sheet, which correspond to the pattern of the sheets.
- Fastening is carried out in increments of 20–30 cm based on the parameters of the profiled flooring pattern. Overlapped elements are fixed to the already installed bars, screwed with self-tapping screws through the upper corrugation.
Attention!
Note that self-tapping screws must be equipped with rubber or neoprene seals.
- To get the most durable and high-quality connection, it is recommended not to screw in all the hardware at once. It is advisable to make fragments for two to four hardware each. The rest are tightened only after checking the cord and level. Agree that every extra hole in the roof poses a potential threat to its reliability.
