# Gable roof with his own hands, the unit truss system

Popular and common type of cover home is a roof with two slopes. The reasons for the apparent preference are a relatively simple technology of construction, speed of installation and the possibility to prove to himself that the gable roof with their hands - attainable goal .

The right materials, tools, desire and necessary knowledge to help cope with the construction of the structure. However, before starting work should be given the utmost attention to a perfect calculation of all necessary parameters - tilt angle, load level, size and number of individual elements.

Ignoring important safety requirements of buildings can lead to disastrous results, sometimes even to the collapse of the roof.

Our calculator gable roof will make a convenient calculation of the future design, and rafters calculator calculate the main parameters and dimensions of the rafters.

### Design features

Before you begin construction the most important element of your home, is to learn how to make a gable roof and determine priority actions. For this you need to be aware of what constitutes standard construction of a gable roof.

Bearing elements it is mauerlat , designed to distribute the load on walls, and resting on it, the system - rafter feet, the ridge, purlins, strut, struts, girders, purlins. Each element performs a specific function and together they present the device a gable roof.

Truss system gable roof is of 2 types - naslonnye and hanging . The first option is selected in the presence of internal load-bearing walls (or pillars) and size of span 10 meters and more. Naslonnye rafters, the lower ends rest on the outer wall, and the average part - bearing capacity.

The second (hanging from rafters) applies if the distance between supports does not exceed six to nine meters. In this case, a support for the rafters are the side walls. To the resulting arching load did not cause harm to the walls, use roof fastening leg hit.

Most often used a gable roof, where the rafters of rest in a rigid support, the side walls are the sides of an isosceles triangle. Additional console part - fillies exclude the ingress of precipitation to the walls of the structure.

The best material for the elements of the truss system gable roof is softwood. It is quite easy to work with and affordable. Unlike metal construction, wood is lighter and allows you to build a gable roof with his hands.

The size of the beam depends on several parameters - the length of the rafter, the angle of the installation, loads the weather and a proper roof, the material chosen for the roof. The most common use of timber with a width of 10-15 cm and a thickness of 5 cm when the length of the rafter not more than 6 meters. The distance between the rafters in this case is usually an average of 1 meter.

If, instead of timber you prefer the boards, their settings should be 50 x 150 mm or 60 x 200 mm, and the distance between the rafters is reduced to 0.6-1.0 m.

Mauerlat must seamlessly serve as a Foundation, so for him to choose a timber with a cross section of 10 x 10 cm 20 x 20 cm At the design stage it is very important to calculate all the loads and with the light of the results obtained to plan the placement of rafters and other elements of the system.

The angle of slope of a gable roof

One of the most important conditions for the proper functioning of the gable roof is the choice of tilt angle . This figure is in the range of 20° to 45° and sometimes goes beyond that. On average, roofs with two slopes projecting at an angle of 35-40 degrees.

The calculation should take into account many factors: the climatic conditions, the material of the roof, the General design of the building. Too little slope does not ensure the convergence of snow and water runoff, excessive increases the pressure of the wind. However, in the second case, the problem is solved - you just need to take measures to strengthen the sheathing and rafters. But if the house is in a zone of constant strong winds, it is better to make the slope more gentle.

If winters in your region is long and generous with precipitation, to fight with snow cover should increase in angle to 45°. However, it is necessary to take into account the kind of material you have chosen for future roof - corrugated sheet, slate, metal or membrane roof.

We offer you a convenient service - to calculate materials for a gable roof with the help of our calculator online.
