A composition shingle roof replacement in Seattle typically costs $8,000 to $15,000 for an average home. Asphalt composition shingles remain the most installed roofing material in the Pacific Northwest because they deliver reliable weather protection, curb appeal, and long-term value at a price point most homeowners can work with. They are available in three grades (3-tab, architectural, and designer) with lifespans ranging from 15 to 40 years.
Over 80% of homes in the greater Seattle area use composition shingles, and for good reason. The product is proven in our climate, widely available from every supplier, and familiar to every building inspector in King, Snohomish, and Pierce counties. If a shingle is ever damaged, finding a matching replacement is straightforward. That kind of market availability translates to faster repairs, competitive pricing, and a deep local knowledge base for installation best practices.
