About this tool

Roof cost planning without the fake exact quote.

Roofing Cost Calculator is a homeowner planning tool for comparing common roof replacement paths before calling contractors. It estimates roof area from home footprint, applies pitch and waste factors, then compares installed material ranges, tear-off, flashing, and optional decking allowances.

The calculator is not a roofing contractor, does not replace an inspection, and does not sell your project as a lead. It is built to make budget ranges easier to understand before you ask for local quotes.
