Documents · not estimates

The roofing facts nobody puts next to the price.

Anyone can tell you what a roof costs. We publish what happens after: what a “Lifetime” warranty actually pays in the year your roof fails, how insurers count hail damage, and how long each material really lasts. Every figure is quoted from a named published document, with the date we verified it. When you want a price on your own roof, we connect you to one vetted local contractor. Never resold, never a call centre.

The guides

What this site is

A reference site, run by reading primary documents: manufacturer warranty documents in full, inspector-association standards, federal energy research. Where we can only estimate, as with install pricing, the figure says so on its face. Where we cannot verify, we do not publish.

Partner contractors are chosen on performance and pricing only. Placement is not for sale, which is what keeps the facts above worth reading. How partners are sourced.

TheRoofFacts.com is a publisher, not a roofing contractor. We do not perform roofing work. When you request an estimate we pass your details to one local roofing contractor who serves your ZIP code, and they pay us a referral fee. We do not sell your information to anyone else, and we do not pass it to more than one contractor.
