How we rank roofing companies

Colorado has no statewide roofing license; every metro city licenses separately. We confirm a current license in each city where a company appears in our rankings, plus a certificate of general liability insurance of at least $1M and active workers' compensation coverage. We ask for documents, not assurances, and we re-verify on a recurring schedule. A company that can't or won't produce these doesn't appear. Period.

After every Front Range hailstorm, out-of-state crews flood the metro, install fast, and disappear before their workmanship fails. We weight years operating under the same name, a verifiable street-address office in the metro, Colorado Secretary of State registration history, and year-round local crews. A warranty is only as durable as the company behind it.

Most Denver roof replacements are insurance-funded, so a good roofer must scope with adjusters, document supplements with photos, and help homeowners recover depreciation correctly. We also screen for the dark side: any evidence of deductible waiving or rebating (which is illegal in Colorado) is an automatic disqualification.

Manufacturer warranties cover materials; the workmanship warranty covers the installation, where most roof failures actually originate. We evaluate the length and written terms of each company's workmanship coverage, whether it's transferable, and (where we can find evidence) whether the company actually honors it in years three, four, and five.

We analyze review patterns across Google, BBB, and other platforms, looking past star averages to complaint themes, how disputes get resolved, and how companies respond when something goes wrong. Recent reviews are weighted more heavily than old ones, and a suspicious wall of five-star reviews posted in a single month is a flag, not a credential.
