Roof Replacement Cost Calculator
A free, practical calculator. Your inputs stay in this browser.
How it works
Enter your roof area, roofing material, whether the old roof is torn off, and how complex the roof is. The calculator applies installed cost ranges per square foot — materials plus labor — and shows a low–high planning estimate.
Example
Try the prefilled 2,000 sq ft asphalt-shingle roof with tear-off and moderate complexity: about $12,100 – $22,000 installed.
FAQ
Does the estimate include labor?
Yes. The per-square-foot ranges are installed prices — materials plus labor, which is how U.S. roofers typically quote.
How much does tearing off the old roof add?
About $1–$2 per square foot for removal and disposal, which is why the calculator asks about it separately.
Why is it a range instead of one number?
Labor rates, roof pitch, and local markets vary widely. Use the range for budgeting and get at least three local quotes before committing.
