What Should Be Installed First: Roof Sheathing or Fascia?

Discover why roof sheathing must be installed before fascia for structural support and effective water runoff in roofing projects.

10 views

Roof sheathing goes on before the fascia is installed. The process ensures that the roofing structure is adequately supported and protects the integrity of the building’s exterior. After the sheathing, the fascia is attached to the edges of the trusses or rafters, providing a finished look and a mount for gutters. Prioritizing this sequence helps in maintaining structural integrity and ensuring effective water runoff.
