The cost to install a metal roof in Seattle ranges from $9,700 to $36,370, with most homeowners paying around $18,180. Your actual cost depends on several factors specific to your home and the Seattle-Tacoma market.
Standing seam is the premium option ($10–$16/sq ft) with hidden fasteners. Corrugated is most affordable ($4–$8/sq ft). Stone-coated offers a shingle-like appearance ($8–$12/sq ft).
Valleys, hips, dormers, and skylights require custom flashing and cutting, adding labor time and material waste on complex roofs.
Removing old roofing adds $100–$150 per square. Metal can sometimes be installed over a single layer of asphalt shingles with proper preparation.
Synthetic underlayment or ice-and-water shield is essential under metal roofing — it adds $0.50–$1.50 per sq ft but prevents moisture issues.
Ridge caps, drip edges, valley flashing, and wall flashing are the details that make or break a metal roof installation — quality flashing prevents leaks.
The Pacific Northwest has moderate to high labor costs. Rain affects exterior scheduling October through April. Green building practices are common and many contractors specialize in energy-efficient work.
Budget $135–$675 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Most roofing materials perform well in mild climates. Longer installation seasons mean more contractor availability and potentially better pricing year-round.
This project requires a licensed professional in Seattle. Attempting metal roof installation without proper licensing can void insurance and create serious safety hazards.

Most metal roof installation projects in Seattle take 3–7 days to complete. The timeline depends on project scope, contractor availability in the Seattle-Tacoma metro area, and seasonal demand. Scheduling during Seattle's off-peak season (typically winter months) can reduce wait times and may lower costs.
Metal roofs cost 2–3x more than asphalt shingles upfront but last 2–3x longer (40–70 years vs 20–30). They also reduce cooling costs by 10–25%, withstand high winds better, and often qualify for insurance discounts. If you plan to stay in your home long-term, metal is often the better value.
With proper underlayment and attic insulation, a metal roof is no louder than asphalt shingles during rain. The old perception of noisy metal roofs comes from barn and shed roofs installed directly on rafters without underlayment or insulation.
