For one- and two-family dwellings, homeowners can often bypass a standard building permit by submitting a 'Roof Replacement Affidavit' to the SDCI. However, commercial and multifamily projects require a permit, which carries a base fee of approximately $146 in 2026.
In 2026, the cost for a standard asphalt shingle roof in Seattle ranges from $6.71 to $14.00 per square foot. Premium materials like metal or cedar shake can increase this to $18.00–$35.00 per square foot.
A metal roof is a significant upgrade, typically costing between $15,000 and $35,000 for a standard home. This is roughly 2 to 3 times the cost of an asphalt shingle replacement, which averages $11,799 to $16,986.
Seattle roofing costs are 21% to 28% higher than the national average due to high local labor rates (averaging $68/hour), specialized moisture management requirements for the PNW climate, and a 2026 increase in city permit and administrative fees of up to 18%.
