About Roof Replacement Cost Guide

Roof Replacement Cost Guide is an independent research and pricing resource for U.S. homeowners planning a roof replacement. We aggregate contractor bid data, materials pricing, permit fees, and regional labor rates to publish transparent, up-to-date cost estimates for every state and hundreds of metro areas.

We are not a contractor and we do not sell leads. Cost figures on this site are national and regional averages published for planning purposes — always obtain 2–3 written bids from licensed, insured, locally-based contractors before making a purchase decision.

How we calculate pricing

Our national baseline is $8.50 per installed square foot for a standard architectural asphalt shingle roof — the U.S. residential median for 2025. We then adjust that baseline by state and city multipliers derived from local labor markets, cost of living, insurance-required assemblies, and climate factors.
