The roof( gable roof) gives the house an exquisite look. The special design of the roof allows to additionally protect the building itself, its walls from the effects of moisture. Therefore, the construction of a roof with four slopes is optimal for regions with high precipitation and strong winds.

Stages of construction of a four-slope roof
The first stage of building a roof is to determine the purpose of the roof( covers the attic floor, attic, etc.), the choice of the roof material( depending on thisthe list of materials for construction is defined), taking into account the atmospheric conditions of the place where the roof will be used( wind, rain, snow).
Choosing a hip roof will give the structure greater resistance to rain and make it more durable( the rafter system is more reliable).The main difference between this type of roof and the gable roof is that instead of the side gables there are two triangular roof slopes.
When choosing the angle of inclination of skates, account should be taken of the level of precipitation and the wind characteristics of the terrain. At small and average average annual precipitation, the angle is recommended to be selected within 4-40 degrees. With abundant snowfalls and prolonged rains, the recommended optimal angle of slopes is 40-60 degrees.
As a material for the roof can be: roll roofing, tile or metal.
Depending on all the above nuances, the thickness and other parameters of the wooden component of the gable roof will be chosen.
The end result of the first stage is the creation of a scheme of the future roof, on the basis of which the construction will be carried out.
We will describe the further technology of how to make a gable roof with our own hands.
The second stage is to build a base for the roof. The base is used to evenly distribute the load from the roof to the bearing walls. The construction of a gable roof assumes a foundation that can be built on its own - a wooden mauerlat and a platform. Under the base for prolonging the service life of the roof waterproofing is necessary. The hydrobarrier is provided with a Mauerlat on the outer contour of the building( the size of this bar varies, either 100x150 mm or 50x150 mm).
A log-beam located in the plane of the base of the rafter system at the same distance from the two lateral Mauerlats. It serves as a support element for the struts and racks, so it is laid on the load-bearing partitions( see the drawings of the gable roof).Large roofing structures can provide several lezhney.
The third stage is the direct installation of the roof frame( base, rafters, lathing).
Constructively different construction of the roof in the house with existing floors or without them( in this case there is no need to lay the beams on which the supports will be installed).
The installation of racks( vertical supports of the roof frame) should be approached with the utmost care. It is necessary to precisely maintain the installation angle( 90 degrees).At the slightest deviation, further deformation of the roof is possible. Step installation of racks - up to two meters.
The device of a four-slope roof of the house consists of four planes( skates).Two trapezoidal and two triangular. Trapezoidal rays will be formed by side rafters, hips( triangular slopes) - with oak( diagonal) rafters.
The rafter at the top of the frame is carried into the ridge bar( run).This bar goes on top of vertical racks( it is possible to make a slot connection with the posts).The distance between the rafters is from 50 to 150 cm( according to the roof plan).The recommended width of the board rafters is 150 mm.
The frame is fastened with corners and steel plates with self-tapping screws( nails).To strengthen the obtained design, diagonal supports, struts, wind beams are used. They allow to increase the permissible load of the system.
Over the rafters the waterproofing is laid. Then a restraining bar is made( bars that are attached to the rafters over the waterproofing).It is needed to create a ventilation duct between the roofing material, crate and waterproofing. This will quickly and effectively remove moisture. Next, the crate is performed - the horizontal boards are attached from the bottom to the top to the control bar( see the scheme of the device for a four-pitched roof).
The final step is the installation of the roofing material. Installation is made depending on the material parameters. An example of mounting metal.
Thus, installing a four-slope roof is a laborious process that requires a careful approach. For a deeper understanding of the structure, you should view photos and video materials.
