How does the roof replacement cost calculator work?

It multiplies a local per-square-foot material cost by your roof size, then adjusts for your city using a location factor derived from federal regional price data (BEA RPP). The result is an estimate, not a quote.

Roof area is larger than your home's floor area because of pitch and overhangs. A 2,000 sq ft single-story home often has roughly 2,200–2,600 sq ft of roof. For a precise figure, a contractor will measure it.
