Today, houses with a multi-gable roof have become quite common. Such buildings are distinguished by a very original design. But not everyone will undertake to build a multi-gable structure, since only special construction companies can do it. The cost of such services is quite high, so not every owner can afford to build such a structure. However, the results exceed all expectations. Let's see what are the features of such a roof and how it differs from others?
Features
A multi-gable roof is a rather complex structure that includes many structural elements (slopes, gables, ribs, valleys, etc.).
This type of roofing is used mainly in the construction of houses with a complex polygonal shape, atypical layout, with a large number of rooms and where there are additionalextensions to the building.
Building a multi-gable roof is a rather costly business, since a lot of roofing material is needed, and a large amount of its waste remains after work. It is also recommended that you take care of high-quality ventilation of the attic space and complete isolation from heated rooms.
A multi-gable coating is formed due to the installation of several slopes and the creation of internal corners - valleys, along which the main part of atmospheric precipitation flows.
One of the disadvantages of this design is the complexity of its construction and the large expenditure of time and effort. This type of roof is most often found in the construction of private houses.
A multi-gable roof can be simple with two slopes or multi-slope with several slopes.
Today, half-hip structures and two-level coatings are considered very popular.
Benefits
Among the positive characteristics of multi-gable roofs are:
- Unusual and very attractive appearance. The design can be completely different, depending on the parameters and functionality of the building.
- High strength and reliability. This type of roof is able to withstand heavy loads on its surface without changing its original appearance.
- The durability of the structure, the service life of which is unlimited. True, it must be borne in mind that the material used and design play a significant role here.
- Practical. Thanks toslopes located at a large slope, rainfall does not accumulate on such roofs.
- Efficiency. The space under the roof can be used as you wish.
Flaws
In addition to many advantages, a multi-gable roof also has certain disadvantages, which should also be remembered.
- The complexity of the construction of such structures, associated with the presence of many elements (tongs, slopes, ribs, etc.). Such work requires professional training. If you are building a multi-gable roof with your own hands, in order to avoid mistakes during construction, you should get advice from experts in this field who will help you develop a roof project, tell you how to take into account the load of roofing materials on the truss system, etc.
- A significant amount of waste building and finishing materials, which, due to the fact that the multi-gable roof has a certain number of slopes, ribs, bends, etc., will be used irrationally.
Recommendations for drawing up a construction plan
1. The project of any house can be made using modern computer programs. It's not difficult, the main thing to consider:
- Parameters of the building under construction;
- Number of bearing structures;
- Roof loads and what material will be used;
- The depth of the base.
2. You need to know what elements the roof consists of and its main features.rafter system.
3. It is necessary to correctly distribute the load of the load-bearing beams and rafters on the walls of the house, since it is they who guarantee the stability of the roof. It is important to understand that the smaller the distance between the rafters and the beams, the stronger the roof.
Materials for building a house
Since the multi-gable roof exerts heavy loads on the structure, experts advise building houses from durable and reliable materials:
- shell rock;
- brick;
- aerated concrete;
- foam block.
Sometimes wood is also used: rounded or profiled timber. Houses in such cases, in order to withstand the load of the roof, must have large dimensions and many load-bearing structures.
To increase the service life of the building, a number of works are being carried out to strengthen it. For example, the foundation of the house is initially strengthened. Ditches are dug along the perimeter of the already finished base, concrete is poured using reinforcement. Load-bearing walls are reinforced with similar materials or special prefabricated metal structures that can be quickly and easily mounted on the inside and outside corners of the building.
Multi-gable roof construction
For the correct drafting of such a roof structure, you should carefully study its device. The building consists of:
- slopes;
- rafters;
- Mauerlat;
- battens;
- oblique and horizontalribs;
- endov;
- skate;
- groove;
- drain;
- overhang.
Multi-gable roof: rafter system
Since the design of such a roof is quite complex, special attention should be paid to its drawing. For this you need:
- measure all sizes;
- choose slope for roof;
- determine the type of rafter system;
- calculate rafters;
- mark the locations of valleys, skates, ribs, vertical posts, puffs, runs, stops and other elements of the truss system.
The basis of the multi-gable roof truss system is Mauerlat. For its construction, bars are used, the size of which is 15x15 cm or 10x15 cm. The length is approximately 1.5 m. It is laid on top of a concrete or brick wall and looks like a connected rigid frame. The mauerlat is attached to the outer walls with galvanized metal studs installed in the armored belt. Rafters (inclined or hanging) are made of boards, the section of which is 5x15 m. At the junction of the slopes, inclined and diagonal rafter legs are mounted. Since the main load will be directed precisely to the diagonal rafters, they should be reinforced with boards of the same size. From above, the rafters are interconnected by a ridge, which you can buy ready-made or make it yourself from boards or timber. On the already installed rafters from the boards, the crate is mounted. To increase the strength and reliability of the cell structure, the battens are made no more than 50x50 cm.
Arrangement of a multi-shield roof
Aftererection of the frame proceed to the isolation of the structure. For these purposes, a simple polyethylene film is used, which is laid on the floors with a call to the Mauerlat.
Depending on the type of roof finish chosen, a base is made. For example, sheet slate can be placed directly on the crate. To mount a soft roof, you will need sheets of OSB or plywood. They are attached to the roof frame, the material is laid out on top. Insulation and insulation of the structure in this case is done from the inside.
Many people give their preference to metal tiles. But due to the low rates of sound insulation, thermal conductivity and other shortcomings of this material, high-quality roof insulation will be required.
