In this article we will talk about what is a multi-gable roof. A multi-gable roof over a square house has a large number of valleys, ribs, gables, gables. The gable is the upper part of the wall of the building, which is limited by two roof slopes and is not separated by a cornice from below. When the upper part of the wall is separated from the lower part by a cornice, then this is already a pediment. The gable roof consists of two planes that rest on the walls and are limited by gables or gables from the ends.
What is a multi-gable roof
Multi-gable roofs are arranged on houses that have a complex layout, with side lighting of attics, covering extensions, gables above the entrances.
When constructing such a roof as four-pitched hip roof, elements such as valleys must be present. You also need to know that a building with such a roof must have a ventilated attic, which will be completely isolated from all warm rooms.
Multi-gable roofs require a large consumption of roofing materials, and after its installation, quite a lot of material waste remains.
Such a type as Do-it-yourself ordinary semi-hinged roof, is formed due to the installation of several slopes. This is a rather complicated construction, the main disadvantage of which is the complexity of implementation.
When constructing this roof, the intersections of the slopes form internal corners (valleys). A large amount of water flows down them and therefore close attention should be paid to the waterproofing of such corners.
In addition, a large amount of snow can accumulate in the valleys, and this significantly increases the load on the roof. The main advantage of a multi-gable roof is its expressive appearance, as well as the overlapping of several rooms with a single-level roof.
gable roof
A gable roof is the heaviest roof in the construction of roofs, since there are many valleys, grooves, and ribs in the design. It is mainly used in buildings with polygonal building design, difficult architecture.
It is often used in the construction of private houses.The spire has an artistic character, and such elements are installed on domed roofs and towers.
These roofs do not carry a useful meaning, but they do a significant job in creating the architectural style of the building. In individual construction, a gable roof is a complex of several forms, sometimes so intricate that it is even difficult to recognize them.
Today, two-level coatings and half-hip roofs are popular.
Your attention! The simplest design is the intersection of two pitched roofs at an angle of 90º.
The rafter system of a multi-gable roof consists of rafters, mauerlat, girders (beams). An element such as a mauerlat redistributes the load from the roof to the walls of the house through the rafter legs and thus connects to the walls.
It consists of wooden bars 150x100 mm and 150x150 mm. And also for this use pieces of timber having a length of 1.5 meters. The rafters for such a roof are assembled from dry pine boards, which have a section of 150x50 mm.
Rafters are hanging and layered - it depends on the presence or absence of additional supports, as well as on the design of the multi-gable roof. In the roof device, both types of rafters can be used simultaneously.
In places where gable roofs are articulated, slanted or diagonal rafter legs are installed, on which the sprigs (shorten rafter legs) will rest. Due to the fact that a very large load acts on the diagonal rafters, they need to be strengthened - to be rallied into two boards.
In the upper part of the rafters, they are connected with a ridge run made of boards or timber cohesive among themselves. If necessary, additional intermediate runs are installed.
Tip! After the rafter system is installed, the waterproofing film is laid in strips, perpendicular to the direction of the slope, with an overlap of at least 15 cm, as well as with mandatory gluing of the joints using connecting tapes. Close attention should be paid to the places where the valleys are located, as large flows of water will flow along them.
On the rafters, bars of the counter-lattice are sewn after laying the waterproofing layer. Basically, bars with a section of 50x50 mm or boards of 32x100 mm are used to perform such work. Sheathing should be carried out in accordance with the instructions for the selected roofing.
Gable roof construction
A lot of owners of private houses want to know how to make a multi-gable roof.
This type of roofs are rather complex structures, and when such a structure is constructed, several fragments of the building can represent gable variations, which are then combined into a single complex, while creating an amazing impression.
Do-it-yourself construction of a four-gable roof consists of the following steps:
- it is necessary to remove the correct dimensions of the house;
- calculate the cross section and length of the rafters;
- correctly position stops, skates, valleys;
- then a Mauerlat should be installed, which should run along the perimeter of the wall and serve as a reliable "foundation" of the roof;
- then it is necessary to install rafters, which are fixed on the Mauerlat with cuts or nails;
- then the crate, waterproofing, the roofing itself, as well as steam and heat insulation are installed.
The design of the multi-gable roof is a pitched roof with sloping roof surfaces towards the outer walls and at the same time provides a natural runoff of melt and rainwater.
The choice of slope directly depends on the climatic conditions of the region, the roofing material and architectural requirements. In some areas, the slope angle is 90º.
The main elements of the roof
The structural scheme of the four-gable roof consists of the following elements:
- inclined planes - slopes;
- rafters;
- crates;
- Mauerlat;
- horizontal and inclined ribs;
- skate;
- valleys;
- grooves;
- overhangs;
- gutters.
The device of a multi-gable roof is a rather laborious process, since additional diagonal rafters should be installed at the intersection of the slopes when erecting such a structure.
In this case, elements such as grooves are formed, which are also called "snow bags". And when installing the roof, special attention should be paid to these elements, since with poor-quality installation, the roof will definitely leak in these places.
Roof forms
With a complex roof, it is necessary to install valleys, which are the least reliable place on the roof, since snow accumulates in these places and the load on the truss system increases.
The four-gable roof is a design of slopes on four sides. It is also called hip or tent, and slopes - hips.
These structures do not require gable walls, but the truss system is more complex than the gable one.Sometimes such a roof is made in the form of a half-hip, and at the same time, the side slopes, as it were, cut off part of the spitz.
Therefore, half-hips have a shorter length along the slope than the main slopes.
They can be located in the form of a triangle, at the very top of the roof, and form a gable in the form of a trapezoid, or a trapezoid anise - then a triangular gable is formed at the top, which lies outside the plane of the wall.
This design is used for buildings that have a polygonal or square plan. A roof with such slopes in the form of isosceles triangles converges with vertices at one point.
