What a New Roof Costs in the Seattle Area

Most residential roof replacements in the greater Seattle area fall between $10,500 and $16,000 for a typical 2,000 square foot roof in composition shingle, including permits and disposal. Material is the biggest single factor, followed by roof pitch and the condition of what is already up there. The price ranges below are rough estimates of what contractors are charging in the Seattle market — not national averages.

Installed roofing cost by material — greater Seattle area
Material Cost per sq ft Typical 2,000 sq ft roof, 4/12 pitch
Composition / asphalt shingle Most common choice in the Seattle area. Lasts 18–35 years here. $5.00 – $8.00 $10,500 – $16,000
Cedar shake & shingle Lasts 18–25 years in the Pacific Northwest unless pressure treated and 100% edge grain. $10.00 – $18.00 $21,500 – $36,000
Metal Highest upfront cost, longest life — 40–50 years. $12.00 – $18.00 $22,000 – $36,000
Flat / low-slope (TPO, PVC, torch-down) Typically 20–30 years depending on the membrane. $9.00 – $13.00 $18,000 – $26,000

What moves the price

  • Roof pitch. A steep roof needs staging and slows the crew down. A very steep pitch adds roughly 40% to labor compared with a walkable roof.
  • Condition of the existing roof. Layers to tear off, and any rotten sheathing found underneath, change the job. A roof which requires all new plywood decking can add 20%.
  • Permits and disposal. Budget $1,500 to $2,500 for permits, dumpster and disposal. Requirements vary by city — see our permit directory.
  • Roof size. Cost scales with area, but not perfectly — setup, delivery and access can all affect the price, as can the number of roof facets.
  • Protrusions. The number of skylights, valleys, dormers and vents all add to the cost.
  • Material price movement. Our suppliers have raised prices four times during 2026 on tariffs and wider supply disruption. Material pricing remains unpredictable, which is why the figures above are ranges rather than fixed quotes.
