Prices are published national installed ranges (mostly HomeGuide, updated Nov 7, 2025), the same ones the roof cost calculator uses, for a straightforward re-roof with one old layer torn off. They are not adjusted for your state; the calculator can do that. Decking repairs, access, steep or cut-up roofs and the contractor all move the final price, so get at least two written quotes.

Squares and the materials list come from the same math as the roof calculator, which works them out for your own measurements.

12/12	2,469 sq ft	24.7	$12,500 – $22,500	$25,000 – $47,500

Published ranges are priced per square foot of roof, so a steeper pitch costs more here only because it has more roof. Many roofers also add a steep-roof charge from about 7/12 or 8/12.
