How the roofing cost calculator works
Estimated total = roof area × material rate + roof area × labor rate + roof area × tear-off rate + fixed extras. Rates are editable and should be replaced with local values.
For a better estimate
- Use roof surface area rather than home floor area.
- Compare quotes that include the same underlayment, flashing, ventilation, disposal and warranty scope.
- Permit, decking repair, steep-slope access and complex geometry can materially change installed price.

How much does a roof replacement cost?+
