What’s different about Lewiston
Lewiston has a lower cost of living and smaller contractor pool, with heavy snow and freeze-thaw cycles shaping roofing and drainage needs.
- Snow load and ice dams call for ice-and-water shield and sturdier decking, pushing roof cost up.
- 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.
