What’s different about Washington
Washington's dense urban permitting, historic-district reviews, and high labor costs make exterior work expensive and slower to schedule than surrounding areas.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
- Algae-resistant shingles are popular where humidity drives streaking.
How the cost is built
Roof cost scales with roof area (measured in 100 sq ft 'squares'), pitch, and material — asphalt shingles are the budget choice, while metal, tile, and slate run two to four times more. Steep or complex rooflines, multiple layers to tear off, and new decking or flashing all add to the total.
