The construction of the roof of the house with their own hands is not easy task, but after complying with certain rules. Divorous roofs are considered the most common, which is explained by their design that allows you to fulfill all the work without the help of specialists. The process is divided into several stages.
1
For the load distribution on top of the brick, block and cast walls are installed by Mauerlat - timber sections 150x150 or 150x100 mm. In wooden houses, the rafter farm is mounted directly on the upper birch or bars. Maurylalat is placed on a couple of layers of rolled waterproofing along the inner surface of the wall and is fixed with spills, corners or thick wires.
2
The beams of overlapping with the same step, as in future rafters, and the removal of the ends behind the wall is determined by the width of the cornice. Next, the installation of rafters is made, their bottom is attached to Mauerlat, the top is on the opposite rafter or on horseback. The latter is performed by timing or two boards located on both sides at an angle to each other. First, extreme structures are set in the form of a triangle, the twine is stretched, which is mounted for the remaining rafting systems.
3
The next step is to mark the crates, it will be solid or with gaps, depends on the type of roof used, in any case a vapor barrier is paired. When the device of a residential attic room is immediately carried out by the warming of the roof, it is important to comply with the correct order of laying the roofing layers.
4
The roof covering occurs at the last stage of the roof construction, but the choice of material should be done at the design stage, to make the necessary amendments. For example, the minimum tilt roof angle is 22 °, and 5 ° slope is allowed in three layers for rubberoid. The use of slate or tile involves the enhancement of the design with additional backups, reducing the distance between the beams and the choice of a larger cross section.
5
Any construction requires drawings, calculating the number of materials, for these purposes there are special programs that are quite complex and, as a rule, paid. Determination of the desired section of beams, rafter legs, clamping parameters and much more can be performed using online calculator, and the calculation of the roof for the bartal roof is available on this link.
Often, ignorance of any subtleties leads to incorrigible errors, to avoid many of them will help the proposed video plot:
