How We Verify
Every listing on this site starts from an official state record — not a form a business filled out, not a review site scrape.
The license layer
We ingest the official license files: Florida's DBPR construction extract (refreshed roughly weekly by the state), California's CSLB master file (refreshed daily), and for Texas — which requires no state roofing license — the voluntary RCAT credential roster. We re-pull on a schedule, and when a license lapses, the listing is unpublished. "Verified" has a date on it, and the date is recent.
The specialty layer
License files say "roofing contractor," not "metal roofer." So we label the evidence behind every specialty claim:
- Roster-verified
- We matched the business (name + location) to an independent industry roster — for example the Metal Roofing Alliance or Tile Roofing Industry Alliance member directories. The claim names its source and the date we checked it.
- Self-described
- The signal comes from the business's own name or public materials ("Smith Metal Roofing"). Real, but not independently certified — we say so, and you should ask them for job photos and product training proof.
What we will never claim
- We hold no review or reputation data — so listings never praise or criticize a business.
- We never state product certifications (impact ratings, code approvals) — those are configuration-specific documents you should ask the contractor to produce for your exact product.
- Listing order is never sold. Featured Partner placements, when present, are labeled as such and never change who appears in the directory.
Found an error?
License files can lag the state's live system. See data corrections to request a fix — we process them against the official record.
