Roof Replacement Cost in Washington State (2026 Guide)
What homeowners in Sumner, Puyallup, Tacoma and Seattle actually pay for a new roof in 2026 — and the line items that drive the price up or down.
Average cost ranges in Western Washington
For a typical 2,000 sq ft single-family home, expect $8,000–$14,000 for architectural asphalt shingles, $15,000–$28,000 for standing-seam metal, and $25,000+ for tile or premium designer shingles.
Steeper pitches, multiple stories, and complex roof geometry add labor cost. Easy-walk single-story ranches are the least expensive.
What's actually included in a full re-roof
Tear-off and disposal of the old roof, new synthetic underlayment, new drip edge, new step and counter flashing at all penetrations, ice-and-water shield at eaves and valleys, new pipe boots, and the shingles themselves. Anything less is a partial.
Cost drivers most homeowners don't expect
Rotten decking discovered during tear-off (typically $80–$120 per sheet of plywood replaced), satellite dish removal, skylight reseals, and chimney flashing rebuilds.
A thorough inspection ahead of time helps avoid surprises on the invoice.
Material grades, simplified
Builder-grade 3-tab: cheapest, shortest life (15–20 years in the PNW).
Architectural / laminate (standard upgrade): 25–30 year warranties, better wind ratings.
Designer / premium: heaviest, best looking, best warranty, but a real cost jump.
Warranty: workmanship vs material
The shingle manufacturer covers material defects. Your roofer covers workmanship (the install). Both matter, and you want both in writing.
