Common questions

How does the roof replacement cost calculator work?

The calculator multiplies the roof area in square feet by material and labor assumptions, then applies a regional multiplier and contingency to produce a planning range.

What should I enter for roof area?

Use the best measured roof area in square feet you have available. If the final scope is uncertain, run one estimate with the current scope and another with a larger allowance.

What does USD per square foot mean?

USD per square foot is the assumed material or labor cost for each unit of the project. Update it when a local quote, product grade, or contractor estimate uses a different unit price.
