Most reroofs are permit-exempt statewide
Oregon's residential code exempts most reroofs from a building permit when the new roofing doesn't add too much weight and doesn't need to be fire resistant. Tearing off all roofing and installing all-new sheathing, homes in wildfire hazard zones, and townhouses can still need one.
