Do-it-yourself multi-gable roof scheme. We make a gable roof with our own hands

The construction term "multi-gable roof" defines a house roof structure that has several gables or gables more than one. A multi-gable truss roof is designed as a complex pitched rafter system. Thus, if there are several gables or gables near the wall of the building, the roof of such a design can be called a multi-gable roof. Original roofing systems can be found not only at historical sites, in ancient manors or castles. Building fashion has carried the demand for multi-gable roofs into modern times, and now most private cottages are built with such roofs. Companies offer customers a wide variety of projects of complex rafter systems, which are the basis of gable roofs, even if the construction is expensive.

Functional load of a multi-gable roof

Such a roof performs many tasks - from technical and operational to aesthetic and design. Therefore, the project must be worked out in all directions, all elements and parts of the gable roof with their own hands must have high precision and reliability. It is also desirable to make design changes to the project that make the roof of the house unlike other structures.

Even a standard gable roof with two gables can be attributed to multi-gable structures, but the roof will be called a two-gable roof. When developing a scheme for a roofing system with paired gables or gables, the roof acquires a complex multi-gable orientation.

The complex truss system of a multi-gable roof is quite feasible on its own, subject to all building rules and recommendations. Before the final choice of the project scheme, you should at least superficially familiarize yourself with the different options for arranging multi-gable roofs, the photos of which are presented below in the figures:

A complex multi-gable roof has the right to life in the following non-standard situations:

1. If the style of the building requires compliance with the solidity of the architectural composition;
2. If one or more buildings are attached to the main building;
3. If it is decided to decorate a rectangular or square house with additional gables;
4. During the construction of recessed windows, loggias, balconies on the roof;
5. If the requirements for the attic do not provide for enhanced natural daylight;
6. Also, a multi-gable roof is being built in houses with a large number of residential and technical premises. It can be low-rise residential buildings or a one-story house of a large area. large area.

Design pros and cons

The architecture of the building only benefits from the construction of a multi-gable truss system.

The advantages of such a structure are enough to make a choice in its favor:

1. Unusualness, originality, aesthetics and harmony of a building with a multi-gable roof are immediately visible;
2. The design is reliable and durable precisely due to its complexity - multidirectional fastenings of rafters and gables due to numerous stiffeners level all types of loads - lateral, impulse, shock, weight and wind, and also negates the influence of atmospheric phenomena, such as heavy snow or deg. Snow flows will not be held on steep roof slopes, so it is necessary to design a reliable storm sewer with a large capacity;
3. The presence of several gables is a great opportunity to equip one or more additional residential or technical premises on the top floor;

Negative moments influencing the choice of project:

1. The high cost of the system due to the large number of building materials, complex construction work and construction time;
2. The construction of such a system involves a lot of scraps of roofing materials, and other waste building materials;
3. The complex geometry of the roof makes it necessary to calculate the dimensions of the parts with a high degree of accuracy, for which it is easier to use an online calculator. It is not recommended for non-professionals to mount the structure - it is more reliable to contact a regional construction company;
4. high-quality waterproofing is necessary, especially at internal joints;
5. Great pressure on the valley in winter.

Design nuances

Typical designs of houses with a multi-gable roof include a pitched rafter system with a slope to the walls of the building. This allows you to effortlessly ensure rain runoff and snow melting. The structural elements that make up the roofing device are as follows:

1. A slope is a fragment of a roof without bends and turns;
2. Gable (pediment) - the upper fragment of the outer wall, the boundaries of which are determined by the slopes of the roof. There is an insignificant difference between a pediment and a gable: gables do not have a cornice at the bottom;
3. Endova (groove) - internal corner joints of the roof, which appear at the joints of the slopes. At the end, the valley ends at the border of the pediment. The valley is the most loaded part of the roof structure, as snow and rain flows constantly accumulate in the inner corners (see photo above). During construction work, it is she who needs to be given special attention in order to avoid problems associated with the appearance of leaks in the future.
4. Edge (ridge - a horizontally located joint, which is formed by connecting adjacent slopes;
5. The overhang provides connection of a roof fragment with a width of 300-500 mm. The main function of the overhang is to protect the building from rain and snow, the maximum possible drainage of rain and melt water;
6. The drainage system diverts water from the roof into the drainage system;
7. The junction is a fragment of the junction of the slopes with the outer wall.

1. Skate;
2. Gable detail - wind or end rail;
3. Lower valley;
4. Upper valley;
5. Dropper - eaves plank;
6. Snow retention bar;
7. adjoining plank;
8. Ventilation shaft cover;
9. Ebb on the window;
10. Fronton L-bar for the outer corners of the roof;
11. Soffit;
12. Ventkanal sheathed with profiled sheet;
13. Window in the attic;
14. Wall J-channel;
15. Gutter.

Step-by-step process for building a multi-gable roof

The assembly of a multi-gable roof is carried out in compliance with the requirements specified in the project. The steps are:

1. First, it is necessary to systematize climate data in the region; climate data - they will be useful in calculations and in the preparation of project documentation;
2. Project development and calculation of building materials, project budgeting. This step is quite difficult to do on your own, so do not be stingy - put the work in the hands of professionals. It is also recommended to pre-compile a list of building materials, their quantity and approximate dimensions;
3. The first practical step is to mount the Mauerlat around the perimeter of the outer walls of the house;
4. Installation of vertical supports and fastening of horizontal girders to form a ridge;
5. Assembly of support beams that determine the shape of the transition and docking of the slopes;
6. The truss structure is reinforced with struts for a more even distribution of loads;
7. Parts are fastened with metal hardware - steel plates, staples, threaded studs or anchors;
8. On the rafters on the outside, a frame of slats is assembled for attaching the roofing material.

The design of the frame is determined by the choice of roofing. When installing a soft roof, it is better to mount a solid frame, without gaps. If the roof will be covered with hard roofing materials (metal tiles, corrugated board, corrugated board), it is allowed to make gaps between the slats or boards in the frame.

Protection against moisture and heat loss

Waterproofing materials in rolls are very easily rolled into strips and overlapped (overlap - 100-150 mm), perpendicular to the slope. The joints of the rolls are sealed with a special adhesive tape or construction tape. Joints and seams on the valleys need to be sealed especially carefully - with two or three layers of tape or adhesive tape.

If the laying of waterproofing layers was carried out with violations of the technological process, using low-quality materials, then you should expect the corresponding consequences - moisture will collect under the roof, the heat-insulating layer of the roof will get wet, wooden beams and rafters will rot and mold.

A couple of decades ago, glassine and roofing material were the most popular material for roof waterproofing, but time and technology do not stand still. Innovative waterproofing membrane coatings (films) are able not only to retain their performance characteristics much longer, but also to comply with the requirements for environmental friendliness and safety of people living in the house.

When assembling a multi-gable roof, additional unoccupied space appears in the attic, and it is possible to equip residential or technical utility rooms in it. In view of this additional opportunity to expand the space, the roof must be well insulated and protected from atmospheric moisture. Mineral wool and other similar insulations are ideal for complex roofing, as they can take on any shape. A layer of soft heat insulator prevents the formation of "cold bridges" - it is in them that moisture first appears. For the manufacture of mineral-based thermal insulation, basalt or glass are best suited. The advantages of these materials for surface insulation are obvious:

1. Low weight insulation;
2. High fire safety and fire resistance (NG group);
3. Environmental friendliness of operation.

Mineral wool also absorbs noise, which is important for all residents of the house.

How much does it cost to build a multi-gable roof

Drawing up a project, costing estimates and quantities of building materials, time and labor costs - all these parameters can only be calculated with a high degree of accuracy by professionals. An independent approach to such a responsible business can result in significant financial losses. Therefore, you should not save on the services of specialists - your costs will pay off handsomely.

If the structures are designed and built in compliance with GOST and SNiP, then the result will be as follows:

1. The house will look neat and beautiful, I spit on no one else's design will make it unique;
2. Long-term resistance of the roof to atmospheric phenomena and other loads is provided;
3. Housing will acquire additional free space, which you can equip at your discretion.

The cost of building a multi-gable roof and carrying out preparatory work (drawing up a project and other necessary documentation) depends on the quality and cost of consumables, the complexity of assembling structures, and the level of employment of workers. Therefore, the approximate cost can be determined only after all the prerequisites for construction have been met - calculation of materials, design, hiring a team of professional workers.

There are a large number of types of roofs that are built for a particular building. The multi-gable roof is considered the most difficult in design and installation. Despite this, she is very attractive and truly decorates the house, for which she is in demand among "wealthy" people. Such a construction is erected on houses with a square or polygonal shape, and on those to which rooms are attached above or below the main building. It is also installed in attics that need special lighting, and in houses with a complex layout.

The main advantage of a multi-gable roof is its beautiful design. It is able to cover several rooms with one level. In general, this roof does not perform any useful functions, “working” mainly for the architectural style of the building. In another way, it is called tent or hip, and slopes - hips. Currently, the most common half-hip roofs and two-level coatings.

Gable roof construction

It consists of three main elements that distinguish it from others: tongs, a large number of valleys, gables and grooves. It is a pitched structure with sloping roof surfaces to the outer walls, which ensures a natural runoff of rain and melt water.

The gable is the upper section of the wall, bounded by two roof slopes. At the same time, it is not separated in the lower part by a cornice, in contrast to the pediments. Endova - a structural element, which is the internal corners at the joints. Any gable roof consists of planes resting on the wall at the same level. From the ends they are limited to gables or tongs.

Square houses with multi-gable roofs look beautiful

A rather important part of the roof - the valley - during operation takes on the largest part of precipitation, rainwater and snow accumulate in it. Therefore, during construction work, she needs to pay close attention, otherwise she will “suffer” from leaks.

The next element of the roof is the rib. It is formed as a result of the connection of the slopes and represents the outer corner. An example of a rib is a place where two slopes are fastened together on a quadrangular roof.

A do-it-yourself multi-gable roof is a rather expensive undertaking, primarily due to the large amount of materials that are spent on the truss system and the roof due to its complex geometric shape. After the work is completed, a lot of waste is generated, especially if metal tiles are used for the roof. It is not necessary to independently build a multi-gable roof without thorough knowledge in this area. It is better to turn to professionals, because the construction of such a complex structure is not without nuances.

Endova. Atmospheric precipitation converges on it and flows down from it, so you need to pay special attention to its device.

The truss system of a multi-gable roof is also not so simple, since it often combines layered and hanging rafters, so the calculation of their cross section, the installation of stiffeners must be done especially carefully.

The simplest version of a multi-gable roof is two gable structures connected at right angles. When viewed from above, this structure will look like a cruciform figure. Most often, several parts of the building may contain gable structures, combined into a single whole. It is they who give the building a bizarre appearance.

The main elements of the rafter system are Mauerlat, rafters and beams:

• Mauerlat redistributes the load from the roof to the walls. It is made from a bar with a length of 1000 - 1500 mm and a section of 150x150 or 100x150 mm. So that the forces from the rafters do not push the walls apart, the Mauerlat must be firmly attached to the reinforced belt, which is erected during the construction of the walls. After that, the rafter legs are installed.
• For rafters, bars of the same section are used as for the Mauerlat. They can be inclined or hanging, depending on the presence or absence of additional supports.
• A ridge is made from the bars, which connects the upper parts of the rafters. Sometimes it is necessary to install additional intermediate runs.

Step-by-step instructions for building a structure

During construction, the following steps must be taken:

1. First you need to correctly measure the size of the house. For professionals, all calculations will be easier. It will be difficult for a person who does not have experience in the construction of such complex structures to navigate the position of girders, mauerlats, etc., so the control and advice of an experienced builder will come in handy.
2. Calculate the length and cross section of the rafters. They are made from conifers. The moisture content of wood should be no more than 20%.
3. Then you need to arrange the remaining elements: stops, skates and valleys.
4. Install the Mauerlat around the perimeter of the wall.
5. Fix the rafters on the Mauerlat with gashes or nails.
6. At the end, there is the installation of battens, waterproofing of the roofing, heat and vapor barrier. Which crate to choose, with what step, depends on the roofing material. For soft coatings, it is necessary to choose a continuous flooring, and for a profiled metal coating or hard roofing materials, the crate is sparse.

A multi-gable roof must have high-quality vapor barrier and waterproofing

The waterproofing film is laid in strips, perpendicular to the direction of the slope. An overlap of at least 15 cm is made, in addition, the joints must be sealed with connecting tapes. Great attention should be paid to the valleys, as they are the least reliable place of the roof and take on the largest amount of water.

The choice of the angle of inclination of the roof depends on climatic conditions, material and architectural features of the building. Sometimes this figure can reach 90 degrees.

During the construction of a multi-gable roof, by default, attic space is provided for the attic. Therefore, the roof should be well insulated. Also, excess moisture should not penetrate into it.

The insulation should be based on mineral fibers, such as basalt or glass. These substances are distinguished by a soft structure, which allows you to insulate hard-to-reach areas of the roof. The insulation prevents the formation of cold zones that contribute to the appearance of strong condensate. Moisture that accumulates in the under-roofing area worsens thermal insulation and leads to rotting of wooden elements.

For attic rooms, additional slopes are required, the same valleys and ribs, as well as rafters and battens

The presence of an attic in the house allows you to significantly expand the usable space. Equipping it, it is worth remembering about ventilation. It is for the attic that it is needed even more than for other residential premises. Traditional types of rolled waterproofing (like glassine or roofing material) do not provide a long service life, strength and environmental friendliness. Therefore, membrane-type materials are now becoming more common, which increase the thickness of the insulation to the entire height of the rafters and significantly reduce the heat loss of the attic floor.

Decide on a price category

Before the construction of a multi-gable roof, the issue of price stands apart. After all, this is not only the most difficult option for building a roof, but also the most expensive due to the large amount of work and expensive materials that require a lot. This design can cost half as much as another type of roof. It is worth paying attention to the fact that considerable loads will fall on the rafter system, so you should buy only high-quality bars.

The arrangement of such a roof will cost at least half the price of another type of roof.

If you build such a roof, then you will have a large space at your disposal, which you can use as you wish. For example, with the help of this roof, wonderful upper rooms and attics are made. Since the angle of inclination of the roof is very large, all precipitation from it quickly rolls off.

Main conclusions

So, as you already understood, building a multi-gable roof is not an easy task. However, if you approach it professionally, then in the end you can get a real “candy house”, in which it is a pleasure to be. In the photo, the multi-gable roof looks very attractive, but in real life it looks even more spectacular if you approach its arrangement creatively.

Multi-gable roof combines attractive appearance and sophisticated installation

The only drawback is that the price of the necessary materials, tools, and roofing services is quite high, which is why this roof is not very popular. Basically, our houses can only boast of a gable or four-pitched roof varieties. However, the attractive appearance and the presence of attic space make a multi-gable roof an excellent option for a private home.

Among the variety of different roofs, the multi-gable one is considered the most difficult.

However, this does not stop those who want to decorate their home with such a roof.

In this article, we will look at what it is and how its design differs from the designs of other roofs.

Such roofs are erected on polygonal or square houses.

Often, various premises are attached to houses, having a different height or equipped with attics in the attic space - multi-gable coatings are erected for various reasons.

The main design feature of multi-gable roofs is the presence of a large number of valleys, grooves and ribs.

Design

The simplest gable roof is a gable roof that does not have gables at the ends.

In this design, the upper triangular part of the wall is called a tong.

If it is separated by a cornice, it will already be a pediment.

The simplest example of a multi-gable roof is the connection of two gable roofs at a right angle.

From above, such a structure is a cruciform figure.

A valley is an internal angle formed between two slopes.

In winter, they accumulate the largest amount of snow, and in summer - garbage.

Attention should be paid to their waterproofing, since leaks most often occur here.

The edge of the coating is formed by the joints of the slopes, unlike the valley, it is an outer corner, for example, a ridge or a connection of two slopes on a hipped roof.

The most complex and critical part of the entire structure is the truss system, it should be calculated and manufactured with increased accuracy and care.

As a rule, either hanging ones are found in it.

We will consider the rafter system separately.

The device and procedure for the construction of the truss system

The basis of the truss structure is the Mauerlat, which is laid along the top of the wall and is a rigid connected frame.

It is attached to the walls by means of metal studs installed in the armored belt.

Since the roof is a rather complex structure, attention should be paid to its drawing.

To do this, it is necessary to accurately measure all dimensions, select the slope, determine the type of truss system used, calculate the rafters, mark the location of the valleys, skates, ribs, as well as system elements - puffs, stops, runs, vertical racks.

First of all, the Mauerlat is laid - it is the basis of the truss system and takes on all the efforts from the rafters, transferring them to the load-bearing walls.

Mauerlat is securely fixed on a reinforced belt, after which the rafter legs are mounted.

For larger houses, longitudinal or transverse ceiling beams are installed, which will serve as puffs.

The rafter legs look like ordinary rafters, and if the roof is hip or semi-hip, the rafters will be diagonal, they will need to be reinforced with sprigs, and they themselves can be double or paired.

The rafters are attached to the Mauerlat by means of cuts, as well as metal plates, brackets, corners - it depends on the type of rafters.

At the top point, the rafters are connected on the ridge, and then equipped with a vapor barrier, crate and counter-crate.

It depends on the roofing material that will be used in the future.

All wooden elements should be impregnated with flame retardants and antiseptics for safety and longer service life.

After the construction of the truss system, the roof is insulated and covered.

Particular attention should be paid to waterproofing, in particular, valleys and grooves - water and snow accumulate in them, and with poor-quality waterproofing, they leak first.

Some features of the roof in question

When choosing a multi-gable roof as an option for your home, keep in mind that the construction of such a roof is a rather complicated and expensive process.

It will take a sufficient amount of material, time, professional skills and so on.

If you are confident in your abilities, do-it-yourself multi-gable roofing (its diagram can be easily found) will not be a big deal.

The issue of cost stands apart - such a design is not only complicated, but also costly.

For this type of roof, as a multi-gable roof, the project must be drawn up with great care and taking into account all possible factors - then the roof will serve for a long time and with high quality.

If you build such a roof, taking into account all the rules, then you will get a roof that will be:

• Stable and reliable - due to the balanced truss system, the roof can withstand heavy loads;
• The roof will make it possible to equip the house with additional space - an attic or an attic;
• The roof will be practical, but its appearance will be very attractive - multi-gable roofs look very nice, and due to the steepness of the slopes, snow and other precipitation do not linger on it.

As you can see, a multi-gable roof is a somewhat peculiar design that requires more expense and effort than other types of roofs.

However, by erecting such a roof, you will greatly decorate your house, make it attractive in appearance.

It will be pleasant to be in it, and if you approach the arrangement of the roof creatively, it will look very impressive.

At the same time, such a roof will be quite practical.

Basic Design Principles

A multi-gable roof is a system of rafters with slopes that are interconnected. The name spitz or pediment is used, but only if the site is separated from the wall of the building. If the wall has several gables or gables, then it is multi-gabled.

The number of forceps is not limited. But most often, designs consist of two, three or four systems. The purpose of the tongs varies.

The installation process itself is complex and costly due to the design features, the amount of materials required.

Source assz.ru

Multi-gable roofs are a common choice for those homeowners who can afford to build a building that looks like a castle. But over time, it became possible to use simpler structures for the construction of tongs in budget country houses.

Construction and arrangement of gable roofs

The upper part of the building, which is limited by two slopes, is called a gable. The complexity of the design directly depends on the number of slopes crossed.

gable

A gable roof is the most popular option in the construction of residential buildings. Its advantages are in the following points:

several options connection angle diagrams;

under the roof there may be an exploited attic or a residential attic;

duration service life directly depends on the materials used;

ease of installation, repair, reconstruction;

tilt angle, thanks to which rainwater and melted snow are effectively discharged.

The supporting frame of a gable roof is built from rafters or roof trusses. The first is used in most residential buildings.

Source krovlyakryshi.ru

The second - during the construction of a building with a large area, where a high operational load will be noted.

Rafters in a gable roof are hanging or layered. The former do not direct the load on the supporting structure due to the lack of support. The second type of rafters has a support - a run mounted on vertical racks.

Hanging rafters are used to create a usable attic or attic. Layered - to enhance the strength of the structure when heavy roofing material is used, or significant snow loads are expected.

A truss truss is a structure that uses straight members and hinged joints to avoid bending loads. The truss allows you to reduce the weight of the frame, increase spans and reduce material costs. Sometimes the structure is assembled on the ground, after which it rises up. This improves the build quality and speeds up the installation process.

A four-slope roof appears as a result of the intersection of gable structures.

Because of this additional structural element, two simple systems form the technological complexity of a multi-gable roof. Difficulties arise in the calculations and installation of parts for a multi-gable roof. If the inner corner has defects, then this can lead to leaks and a violation of the integrity of the coating.

Other types of gable roofs

Multi-gable roofs make it possible to combine different types of structures. In this case, all crossed slopes can have dormer windows.

The gable roof is the best option when constructing one-story buildings with a large floor area.

If the building is made in the form of the letter "P", "G", "T", then in this case only a multi-gable roof can be used. Hip slopes are an effective option for getting rid of gables.

Pros and cons of multi-gable roofs

Benefits:

external view;

possibility use in complex projects;

duration operational period;

can be used in houses from any materials;

does not accumulate snow;

space under the roof can be rationally used;

diversity architectural solutions;

effective drainage.

The pitched roof has the following limitations:

drainage system should be branched;

high material consumption;

high price due to the need to use additional elements in large quantities;

can only be used some from roofing;

competent an approach for design and installation.

How are the dimensions of a multi-gable roof calculated?

The complexity of the calculation process will depend entirely on the individual elements of the project.

Source krovlyakryshi.ru

Specialists lay out the entire project into simple figures to facilitate the calculation.

How is the calculation carried out

The calculation uses a three-gable roof. The calculation starts from determining the height of the ridge, which depends on the width of the building or extension and the angle of the slope. If the problem is solved with another unknown, then first determine the slope angle of the ramps.

When determining the length of the slanting rafter leg, there are some features.

Source roofs.club

The red line is the hypotenuse, and the blue (the length of the rafters of the main building) and green (1/2 the width of the extension) are the legs. The calculations are carried out using the Pythagorean theorem.

Calculation of the length of the sloping valley rafter leg

To determine the length of the sprues, a calculator for calculating hip roof sprigs is used. The calculation procedure in both cases is identical, only the direction of installation of the sprigs changes.

If the rafters additionally perform the functions of a cornice overhang, then the leg length increases. To do this, use a calculator for calculating the elongation of rafters to form a cornice overhang. In some cases, experts resort to the use of extension fillies, but for them it is also necessary to calculate the required length.

Next, the section of the rafters is determined, which completely depends on the loads imposed on the roof. For the correct calculation of the section, additional elements of the support of the rafter legs are placed. An appropriate calculator is used: calculation of a certain unloading on the legs.

To acquire the correct amount of required materials, the area of ​​\u200b\u200bthe roof is calculated. The total area includes:

couple rectangular slopes without taking into account the triangle layered with rafters along the valley line;

couple trapezoidal stingrays.

The main types of connecting nodes

A large number of different types of multi-gable roofs does not allow defining a single system for installation. Connection methods can be simple or complex.

The beginning of the construction of the multi-gable roof truss system begins with the laying and fixing of the Mauerlat to the concrete base. There are 3 types of mounts:

used embedded hairpin threaded. The distance between the studs is approximately 70-80 cm. Holes are drilled in the beam for further fastening 1-2 mm larger in diameter than the studs themselves.

steel smooth wire. The method is divided into two possible variants. The first one is laid across the beam, which eliminates the need to drill holes. The beam is attracted by the wire to the concrete. The second - the segments are mounted along the wall, and the ends go above the formwork. To do this, you will need to drill holes so that the ends can be passed through the timber and twisted.

Using staples. There are several bracket configurations on the market. Models differ from each other in the fastener. Some are attached to the sides or wall through prepared anchors or holes. This method of fastening is the most popular when installing a beam on a wall.

Regardless of the chosen method of mounting the Mauerlat, care must be taken to waterproof the cut-off between concrete and wood. For this, bituminous mastic is used, which processes the surface, and then several layers of roofing material are laid.

Source krysha-expert.ru

Several connection methods are used in the case of attaching an attic floor beam to a Mauerlat.

Using fortified corners connecting the bars to each other with the help of self-tapping screws.

In the traditional way - cutting. To do this, a groove ½ of the thickness is cut out in the Mauerlat, and a spike of shape and size identical to the groove is cut out on the floor beam. The spike is installed in the hole, an additional hammer is used for knocking. In some designs, additional fastening with the help of corners is used.

Using floors in the design of the overhang, they are cut into the Mauerlat, grooves are created in the details with a depth of ½ timber. For additional fixation, metal corners are used.

Fastening the beams on the Mauerlat with steel staples driven into the beam and into the timber.

When attaching a beam to a rafter leg, one of several methods is used:

Fixation of the rafter leg is carried out using staples, the length is set within 25 - 35 cm.

The simplest method of fastening is fixing with corners. To ensure the most snug fit, grooves for the corners are cut in the rafters.

Gable roof manufacturing

The manufacture of the roof is based on a structure consisting of rafters. The rafters themselves are made of wood or a profile pipe. But the stages of work will be largely similar:

Withdrawal sizes.

Definition the correct length and section of the beam.

Unfold valley, stops, skates.

The choice of slope slope is selected depending on the climatic conditions of the region and the wishes of the customer. In some cases, a right angle of inclination is selected.

Frame installation

Installation work of the truss system is carried out in accordance with the algorithm:

Creation waterproofing layer the top of the walls with mastic, roofing material.

Mauerlat mount.

Mauerlat markup. It is necessary to mark the points of attachment of the timber to the ceiling. Between the bars there should be a distance of about 60 cm for filling with insulation.

Over the floor beams must be made draft flooring for which inch boards are used. This is necessary to facilitate movement at roof level.

Installation of central racks.

Installation of a ridge beam on racks.

Frame fixation at using two triangular segments.

Installation rafters for valley formation.

Conclusion

The construction of a multi-gable roof is a complex process that requires not only knowledge, but also skills. Therefore, the construction should be done by professionals. Financial and labor costs directly depend on the number of tongs, the type and features of the project - an accurate estimate can only be obtained after preliminary calculations have been made.

The variety of types of roofs gives architects a lot of room for imagination. Even a simple shed roof can crown the house in such a way that it will look catchy and original. Gable and hip roofs look good, but a multi-gable composite roof is an ideal choice from an aesthetic and practical point of view.

Under such a roof is a comfortable attic, living space with natural daylight. This design is more time consuming and expensive, but the owners deliberately go to the expense. To understand why this happens, it is necessary to understand the features of gable roofs.

The difference between this design and other types of roofing is the presence of tongs located perpendicular to the main roof slope. A multi-gable roof is used to cover both rectangular buildings and more complex polygonal, broken structures.

One of the features of such solutions is the use of under-roof space for residential purposes with daylight through window openings. The gable is a continuation of the building wall with a triangular top with two slopes at the top. It is not limited from the wall by a cornice and thus differs from the pediment.

The most common variants of this design are the three- and four-gable roofs. These architectural solutions are characterized by high cost and laboriousness during construction, require highly skilled workers and improved thermal and waterproofing.

Advantages

But such roofs also have significant advantages, namely:

When choosing the type of roof, it must be remembered that gable roofing requires increased attention at the level of manufacturing the truss system, since the further installation progress depends on the exact insertion of gable slopes into the main roof slope. There are numerous designs for asymmetrical forceps arrangement. But the most popular options are still multi-gable roofs, which are based on a gable rafter system.

gable roof construction

To understand the design features of any roof, you need to find out what elements it consists of. A complex multi-gable roof is no exception, so consider its main components:

To the listed structural elements, additional components and parts can be added, if necessary, to increase the strength and durability of the structure.

It is important to remember that the places of window openings, exits of chimneys and ventilation pipes must be marked in advance and taken into account in the roof structure accordingly.

A multi-gable roof should be covered with a relatively light roofing material in order to reduce the weight load on the nodes and individual structural elements. For convenient operation of the residential under-roof space, all fasteners must be positioned so that they can be easily covered with decorative finishing materials in the future.

As a rule, the tongs have a lower level of the ridge than that of the main roof, therefore, in the valleys, it is necessary to install additional racks and horizontal braces to strengthen the structure, and the ridges rest on the crossbars. If there are horizontal walls on the tong, it is necessary to give them greater rigidity with triangular elements. If the skates on a three- and four-gable roof are at the same level, then the docking is done with a cut or metal corners, and the valleys are attached between the skates at the right angle.

Roof installation procedure

Since the roof structure has complicating elements, an absolutely balanced approach to the installation of the structure is necessary. It is necessary to draw up a drawing with all the necessary dimensions to calculate the required material.

It must be remembered that all wooden elements of the roof structure must be treated with compounds that prevent rotting.

The procedure for assembling the roof must be itemized and strictly followed in strict sequence. . The multi-gable roof is mounted as follows:

• all parameters are measured and applied to the wiring diagram, with the exact location of the skates, tongs, valleys and rafters;
• a layer of waterproofing material is laid out along the perimeter of the walls;
• Mauerlats are laid out and attached along the walls, fixing points to the walls must be prepared in advance and located at a frequency of 1000–1500 mm;
• then puffs are laid, which are fastened with power plates to eliminate the bursting effect on the walls of the building, puffs can be transverse and longitudinal;
• rafters are laid, in the upper part they are connected to the ridge structure, and in the lower part with a Mauerlat with a gash for 1/3 of the thickness of the rafters;
• the rafter group is fixed in a vertical position with temporary bars or a permanent crate;
• for the rigidity of the structure, crossbars, headstocks and struts are installed, and structures are also prepared for the installation of tongs;
• tongs, rafters, valleys are mounted and the structure is fixed with a crate;
• put the finishing crate and remove all temporary fasteners, taking into account the exit of chimneys and ventilation pipes;
• then installation of gutters on valleys, cornice strips and a drainage system, as well as windproof strips on roof overhangs;
• waterproofing is laid and a counter-lattice is mounted;
• the roofing is laid, taking into account the joints of the roof on the valleys, ridges, junctions with pipes;
• heat and vapor barrier is mounted, the under-roofing room is finished.

For each particular house, the sequence of operations has its own sequence, and the structural elements may be different. Therefore, when erecting such a complex structure as a multi-gable roof, consultation with specialists is necessary.

Conclusion

We examined the device of the most complex roof, its design and installation sequence. Do-it-yourself arrangement of a multi-gable roof will save a significant amount, but a very balanced design approach is required in order to avoid damage to expensive material. It is very important to follow the technology so that the roof pleases with durability and beautiful appearance.
