Roofing Cost Calculator
Use this roofing cost calculator to build a planning budget from measured roof area and local rates. Separate material, labor and tear-off costs so you can compare contractor quotes using the same project scope.
Enter project details
Planning estimate only. Confirm local prices, supplier specifications and site conditions before ordering.
Your estimate
Replace the example rates with local values. Decking repair, flashing, ventilation, steep slopes, access and permit requirements can materially change the final quote.
Request local project quotes
Tell us about your roofing installation or repair project. ProjectMetrica uses WiserLeads, the Triares/homeyou lead platform, to check whether a participating buyer is available for your project.
- No purchase is required.
- Availability and matching depend on ZIP code and project details.
- ProjectMetrica may receive compensation for a qualifying accepted request.
The form is submitted to ProjectMetrica first and, when an eligible WiserLeads opportunity is accepted, the required lead data is sent to Triares/homeyou. TrustedForm is used to create a consent certificate for the form session. See the Privacy Policy.
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.

Frequently asked questions
How much does a roof replacement cost?+
Installed cost depends on roof area, material, labor market, tear-off, decking condition, access, pitch and project complexity.
What does cost per roofing square mean?+
A roofing square is 100 square feet, so cost per square is the total project cost divided by roof area in hundreds of square feet.
Does this calculator give a contractor quote?+
No. It is a planning model based on the rates you enter and should be compared with site-specific local quotes.
