Get my exact price →How the calculator works
We start with your home’s footprint and apply a pitch factor to estimate the actual roof area (which is larger than the floor area because of slope and overhangs). We then multiply by a typical installed cost per square foot for your chosen material and add tear-off and complexity.
The result is a realistic budgeting range. The only way to get an exact price is a local roofer measuring your roof, which is free through Roof Restore Buddy.
Roof cost calculator. FAQs
How accurate is the roof cost calculator?
It gives a solid ballpark based on roof size, pitch, material, and tear-off. Actual quotes vary with your roof’s complexity, your region’s labor rates, and the contractor, so always confirm with a few local quotes.
How do I measure my roof size?
Start with your home’s footprint (length × width of the floor area), then the calculator applies a pitch factor to estimate the actual roof area, which is larger than the footprint because of slope and overhangs.
What is a roofing “square”?
A “square” is 100 square feet of roof area, the unit roofers use to price a job. A 2,000 sq ft roof is 20 squares.
