9. Roofing

At this point the roofing is installed, and you’ll need to decide if you want attic space or not. It is common practice today to use prefabricated trusses, triangular wooden structures that support the roofing. They have many advantages, but they limit the use of attic space. Once the trusses are in place, the roof is covered in plywood or OSB, which give the roof its strength.

Once the roof is completed, an inspection will be done to test for safety.
