What’s different about Great Falls
Great Falls's sparse population can raise travel-related labor costs, and high winds with heavy snow load demand robust exterior detailing.
- Snow load and ice dams call for ice-and-water shield and sturdier decking, pushing roof cost up.
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.
