Roofing Permits in Seattle and Surrounding Cities

Seattle Department of Construction & Inspections states that in detached one- and two-family houses, replacing existing roof sheathing or repairing the roof can be permit-exempt when the work does not change the building envelope and the work is equivalent to the existing structure. Owners should review the current SDCI “Do You Need a Permit?” guidance for their exact project.
