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.

10/12	1,921 sq ft	19.2	$9,700 – $18,000	$19,500 – $37,000
12/12	2,087 sq ft	20.9	$10,500 – $19,500	$21,000 – $40,000

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.

Same 2,500 sq ft, one storey or two (8/12, gable roof)

House	Roof footprint	Squares	Asphalt shingles
One storey	2,815 sq ft	33.8	$17,000 – $31,000
Storey and a half	1,926 sq ft	23.1	$11,500 – $21,500
Two storeys (this house)	1,476 sq ft	17.7	$9,000 – $16,500

Two storeys put the same living space under half the roof. The roof is higher and steeper, though, which pushes a quote toward the top of the range.
