FAQ
How does this estimate work?
Roofing Estimator gives you a planning-stage cost range to work from before you call a roofer. Compare the range against any quote you receive and ask a line-item breakdown if a bid sits well above or below it — this is where pricing games usually show up.
What should I check before comparing quotes?
If your quote is below this range: ask whether tear-off of existing layers, underlayment, drip edge, and ice-and-water shield are included. Overlay-only quotes are usually 20-30% cheaper for a reason. If your quote is above this range: ask for a line-item breakdown including material, labor, tear-off, disposal, and permit. Flashing and decking repair should be separate line items.
Is this a quote from a provider?
No. This page is an estimation tool for planning only. It helps you compare scenarios using your inputs and local context, without claiming provider availability or pricing guarantees.
