Basic tips
When installing a pitched roof, do not forget about some nuances:

The slope should be positioned on the windy side so ghana mobile database the roof does not get blown off by the wind.
When calculating the rafter system, you need to take into account the climatic conditions. This is the amount of snowfall, heavy rains, wind force. Uniform distribution of the load on the rafters will increase the service life.
Take overlap into account when calculating materials.
The smaller pitch of the rafters of a pitched roof allows it to withstand a higher load.
Example of a single-pitched garage design
The walls are made of foam blocks. The first thing to do is install the mauerlat. With a pitched roof, these are 2 beams laid on walls of different heights.

We install a 100x150 mm beam on the inner sides of both walls. We install it on roofing felt waterproofing material. This will be our Mauerlat. We fasten the Mauerlat using reinforced 90x90 corners. For this, we use dowels with a diameter of 14 mm.
We take a 50x200 mm board and install it on the wall plate with a reserve of 50-60 cm. The reserve should exceed the planned dimensions of the cornice. After that, all unnecessary parts are cut off.
We mark further cuts on the board, the depth of which should not be more than 1/3 of the width of the board.
We mark the walls so that the last rafters do not touch them. The recommended distance is 4-5 cm.
Using the template, we make the remaining rafters. We fasten them with brackets or corners.
Taking into account the width of the overhang, we make fillies. We mount all the elements of the cornice so that there is a layer of waterproofing between the tree and the wall.
We cut off all the excess and attach a 25x100 mm wind board.
The simplest garage design scheme is complete. The next steps will be installing the sheathing and laying the roofing material.
