We publish roofing cost data for US homeowners who want a number before a salesperson gives them one.
Replacing a roof is one of the largest unplanned expenses a homeowner faces, and almost nobody does it more than twice in a lifetime. That combination — expensive and unfamiliar — leaves most people accepting the first quote they receive with no way to judge whether it is reasonable. RoofPriceBook exists to close that gap. We publish the underlying cost structure openly so you can walk into the conversation already knowing roughly what the work should cost.
Our per-square-foot material and labor rates are compiled from published contractor pricing, manufacturer material costs, and regional labor cost indices for the United States. Regional multipliers reflect the well-documented spread in construction labor rates between rural and major metropolitan markets. We review the rate tables at least twice a year and date every update on the page.
We are transparent about the limits of this. A calculator cannot inspect your decking, cannot see your flashing details, and cannot know what crews in your county are charging this month. We present our output as a range for a reason, and we say plainly on every result that it is a budgeting figure and not a quote.
When a reader chooses to request quotes through the referral link on our pages, we may receive a commission from our partner. This never changes what a contractor charges you, and we are paid the same regardless of which contractor you pick or whether you hire anyone at all. Our full affiliate disclosure explains this in detail.
If you believe a figure on this site is wrong — especially if you are a contractor who prices this work daily — we want to hear about it. Write to us through the contact page and tell us which number, in which market. Substantiated corrections get published.
