What’s different about New Hampshire
New Hampshire's snowy winters and ice dams require durable roofing and drainage detailing, with proximity to Boston nudging labor rates upward.
- 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.
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.
