Supported Roof Types:

Our calculator estimates the cost of materials and warrantied-labor for any major type of roof including the basic 3-tab shingles, architectural shingles, PVC, TPO, EPDM rubber, built-up roofs, cedar shingles, clay tiles, natural, slate, and metal roofing. All prices are based on the US average roof replacement costs as surveyed by the Remodeling Magazine in conjunction with regional pricing data from contractors we've surveyed.

To make your pricing more precise, you can choose the number of floors on your home, number of skylights and chimneys that will need to be properly re-flashed and shingled around, as well as indicate whether or not you want to include the cost of the tear off and disposal of the old roof.
