  • The rafter system is constructed quite simply.
  • Low cost.
  • The speed of construction.

Calculation of the slope

When designing the garage on the plan, it is important to specify the required slope of the cover. It mostly depends on the material with which the roof will overlap, for example, it can be ondulin, roofing felt, slate, metal profile, tile.

For example, if roofing material is selected, then the minimum slope of the roof is 5 degrees, for bitumen tiles to 22, and for high-profile tiles the angle of the slope can reach up to 30 degrees.

Among other things, it is worth considering the location of the building on the site. Analyze in which direction the wind is blowing, how much precipitation falls in your area. To make accurate calculations, you can use the online calculator.

We suggest that you consider the option of making a shed roof on a garage from slate.

For the construction of the roof you will need a set of tools and material:

  • slate;
  • slate nails;
  • unedged boards;
  • wooden blocks:
  • water and steam insulation;
  • wood saw;
  • ax;
  • hammer;
  • brackets and stapler;
  • sharp knife.

A rafter system is constructed for a shed roof. 12 cm bars can be used as beams. A 10 * 20 cm beam can be used as a rafter foot, and 0.5 * 0.5 cm for a batten.

So, a roof slope of 20 ° is made for slate. Partial slope of the roof can be formed by laying walls. One wall will be lower, and it is better that it is located on the side of strong winds. Next on the wall mounted mauerlat. Be sure to perform waterproofing before laying timber mowerlat. As a waterproofing you can put ruberoid. Later, the truss system will be mounted on the power plate. The very same timber is fixed to the wall with an anchor.

Rafters are stacked in increments of 70-80 cm. They need to be fixed to the power plate when relief nails.

For safe movement, lay the boards on the rafters. It will also allow for much faster work.

Next, the crate is made of 50 * 50 mm bars. The crate is nailed across the slate laying.

The next step is waterproofing. To do this, crawl along the plastic film. Be sure to stack the film overlap up to 20 cm. At the same time, the overlap should be in the direction of the slope. Otherwise, running water or condensate may leak into the garage. The film is attached to the rails with a stapler.

In conclusion, it remains to cover the roof with slate. It is necessary to start laying from the bottom up with the help of special nails. Be sure to secure the wind boards, which will prevent the breakdown of the roof.
