Load-bearing structure also called bridging. This rigid structure is the element to which the components of the roof system are attached. It is usually covered with a layer of asphalt felt to protect it from flames.
Next comes insulation. The insulation is installed under the covering of the roof.
Depending on the type of coating chosen, an under layer membrane is attached to the deck. The membrane is glued or mechanically fixed. A finishing membrane is then welded to it.
A ventilation and drainage system is also necessary to ensure the durability of the roof. We are talking here about devices allowing air circulation in the attic and a gutter system to redirect rainwater.
Parapets and flashings;
These elements are essential to the creation of a reliable roof.
The structure of a pitched roof
As a general rule, the frame, also called decking, is made up of large pieces of wood assembled together. Then, wooden slats and rafters are added to the purlins.
The purlins are pieces of wood that are supported on the classic structure of the roof. This classic structure is composed of:
Crossbowmen, which are the elements supporting the purlins;
A tie-beam (horizontal base of the classic structure);
A punch (main vertical part of the classic structure);
Besides the support structure, here are the other elements that make up a pitched roof:
Fascia (roof edge);
Speed bump, installed around the chimney to promote the flow of rainwater;
The eaves membrane;
The base layer membrane;
As you can see, there are a large number of elements that make up the structure of a pitched roof. This is why it is essential to carry out annual inspections to ensure that each of these elements is still functional.
