In Seattle, a permit is generally not required for a simple 'overlay' or replacement of shingles on one- or two-family dwellings. However, if you are replacing the roof sheathing (plywood) or making structural changes, a permit is required, typically costing between $500 and $1,000.
For a typical 2,500 sq ft Seattle home, a metal roof ranges from $40,000 to $70,000, which is roughly 2 to 3 times the cost of standard architectural asphalt shingles ($20,000–$35,000).
Due to the wet PNW climate, 2026 estimates suggest budgeting an extra $1,500 to $5,000 for unexpected repairs such as rotted roof decking, mold remediation, or required ventilation upgrades to meet current energy codes.
A new roof in Seattle typically provides a 50% to 60% return on investment. In 2026, this translates to an average home value increase of approximately $10,000 to $13,000 for a standard replacement.
