Roofing Cost Calculator
Estimate a roofing budget using your roof area and editable material and labor rates.
Project details
Estimated cost
Planning estimate only. Actual contractor pricing varies by location, project complexity, material selection, permits, access and market conditions. Replace the sample rates with local quotes whenever possible.
How to estimate roofing cost
Start with the actual roof surface area rather than the home's floor area. Add a waste allowance for cuts and layout, then apply local material and labor rates.
What can change the final price?
Roof pitch, tear-off, decking repairs, flashing, valleys, number of stories, disposal, permits and material choice can all change a contractor quote. Use this calculator as a budgeting tool, then replace the sample rates with local numbers.

Roofing Cost Calculator FAQ
Is roof area the same as house square footage?
No. Roof slope, overhangs and layout can make roof surface area larger.
Does this include tear-off?
Only if you enter the expected tear-off or disposal amount under other costs.
Are the default rates national averages?
No. They are editable sample values, not a market quote. Enter local pricing.
