Calculate Roof Replacement Cost
To estimate this, multiply your roof's area in 100-sq-ft “squares” by a per-square rate for your material, then adjust for pitch and tear-off. Our cost calculator does it instantly for a ballpark range. Because it can't see your roof's condition or local labor rates, confirm the number with itemized written quotes from local contractors.
New Roof Guide connects you with licensed local companies - we are not a contractor.
GuideHow do you estimate a roof's cost?
An estimate is only as good as its inputs: roof area, material, pitch and whether the old roof is removed. Online tools give a ballpark, but they can't see your roof's condition, access or regional labor rates. Use an estimate to set expectations, then confirm it against written quotes.
How do you get an accurate price?
Estimates and ranges are a starting point - the number that actually matters is an itemized written quote for your address. For the bigger picture, see our what a new roof costs, then request written quotes from local pros. Comparing a few, line by line, is the surest way to a fair price.
