How we localized this

We start from our national asphalt shingle roof replacement range of $7,000–$17,000 and adjust it for Seattle, where costs run about 18% above the national average. Seattle is one of the more expensive U.S. metros for home-improvement work. A cost-index comparison frames Seattle renovation pricing as about 28% above the national average, while the multiplier it actually applies to project estimates is 20% above; other local remodeling guides put the range as high as 25–50% above, largely citing tech-sector wage competition for skilled trades. Mortenson's quarterly index shows Seattle's recent cost growth running below the national pace, which points to a market absorbing pressure rather than one still accelerating — but the underlying level remains high. We apply about 18% above national, close to the more conservative of the cited multipliers. Materials are priced roughly nationally, so treat this as an approximation — your actual price depends on your home, contractor, and project specifics.

Tech-sector wage competition pulls up pay for skilled trades across the metro, and strong, steady demand leaves many contractors with little scheduling downtime. The Seattle Department of Construction and Inspections (SDCI) processes permits online, but timelines vary widely — simple permits often clear in 2–4 weeks, while structural work or an accessory dwelling unit (ADU) can take 3–6 months. Seattle's wet climate makes roofing and decking material choices matter more than in drier regions; composite decking and metal roofing cost more upfront but hold up better against sustained rainfall than wood or standard asphalt. ADU construction is especially active here, driven by the region's housing shortage and comparatively permissive local rules.

  • Shingle grade — Raises cost

    3-tab is cheapest; architectural is mid; premium/designer shingles cost most.

  • Roof pitch & complexity — Raises cost

    Steep roofs and many valleys, dormers, or facets slow the job and raise cost.

  • Layers to remove — Raises cost

    Tearing off multiple old layers adds labor and disposal.

  • Decking repairs — Raises cost

    Rotted or damaged roof decking discovered during tear-off adds cost.

Asphalt shingle roof replacement cost — FAQ

How much does it cost to replace an asphalt shingle roof?
Most homeowners spend about $7,000–$17,000 to replace an asphalt shingle roof on a typical 2,000 sq ft roof, averaging around $10,250. Installed, that's roughly $3.50–$8.50 per square foot depending on shingle grade and roof complexity.
How much is a roof per square?
Roofers price in 'squares' (100 sq ft). Asphalt shingles run about $200–$700 per square installed depending on type — roughly $80–$280 per square for materials alone.
What's the difference between 3-tab and architectural shingles?
3-tab shingles are cheapest (about $3.50–$5 per sq ft installed) and last ~15–20 years. Architectural (dimensional) shingles cost more ($5.50–$8 per sq ft) but look better and last longer — now the most common choice. Premium/designer shingles run higher still.
Does roof size mean my house's square footage?
No — roof area is larger than your home's footprint because of slope and overhangs, usually 1.3–1.7× the floor area. A 1,500 sq ft single-story home often has roughly 1,700–2,200 sq ft of roof.
