What’s different about Billings

Billings is Montana's largest market with the deepest contractor pool, where harsh winters and high snow load demand reinforced exterior construction.

  • 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.
