Reroofing Permit

Apply for a permit to reroof a residential or commercial structure in Portland. A building permit is required for reroofing work. Oregon Building Code limits the total number of roof covering layers to two — if the existing roof already has two or more layers, all layers must be removed before installing new roofing. Structural evaluation may be required when changing to heavier roofing materials (e.g., asphalt to tile or slate). Portland offers expedited review for standard residential reroofing projects.
