What’s different about Wilmington

- Algae-resistant shingles are popular where humidity drives streaking.
- Coastal salt favors corrosion-resistant flashing and fasteners.
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.
