What’s different about Seattle
Seattle carries high labor and permitting costs, Cascadia seismic codes, and a wet maritime climate that together make it Washington's priciest market.
- Earthquake codes can require extra bracing and reinforcement.
- Humidity favors moisture- and mildew-resistant materials.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
How the cost is built
Metal-roof cost is driven by panel type (corrugated and ribbed steel are cheaper; standing-seam, aluminum, copper, and zinc cost more), roof complexity, and gauge. Metal costs about twice as much as asphalt upfront but lasts 40–60 years, so its cost per year is often lower.
