What’s different about Idaho
Idaho's cold winters and mountain snow load require freeze-resistant detailing, and rapid growth around Boise has tightened contractor availability.
- Snow load and ice dams call for ice-and-water shield and sturdier decking, pushing roof cost up.
Expect quotes toward the higher end in Idaho’s larger metros — Boise, Nampa, and Meridian — where labor and permit costs run above the state average, and lower in rural areas.
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.
Resale value
A new asphalt-shingle roof recoups roughly 60% of its cost at resale, per the annual Remodeling Cost vs. Value report — and it's often what lets a home sell at all.
