Supported Roof Types:

Our calculator will estimate your total roofing cost installed, including the cost of materials, labor, and warranty for any major type of roof including 3-tab asphalt shingles, architectural and premium composition shingles, PVC, TPO, EPDM rubber, built-up roofs, cedar shakes and shingles, clay tiles, natural slate, and metal roofing.

All prices are based on national average roof replacement costs in the US, in conjunction with regional pricing data from roofing contractors we’ve surveyed.

To make your pricing details more precise, you can choose the number of floors or levels in your house, along with the number of skylights and chimneys that will need to be properly re-flashed and shingled around. You can also indicate whether or not you want to include the cost of the tear off and disposal of the old roof in your estimate.

    My insurance is replacing my roof due to wind and hail damage. I currently have an asphalt roof. Would my insurance pay for the architectural shingles with venting?

      Hi Melissa,

      We don’t see why they wouldn’t pay for a properly vented architectural shingles roof, as long as the cost of the new roof falls within their maximum allowed payout amount on this insurance claim.

      All else being equal, architectural shingles will last than a 3-tab shingles. Plus, proper venting will help extend the lifespan of a new roof.

      The way we see it, all of the above are in the insurance company’s best interest.

    Many of our asphalt shingles got blown off in the winter storm. Our current roof is 25 years old and needs replacing. We are considering putting on a metal roof because we live in the forest and believe it is more fire resistant than asphalt.
