How to Choose a Roofing Contractor in Denver (2025)

Colorado requires roofing contractors to be licensed at the state level — verify through DORA (Colorado Department of Regulatory Agencies). Denver also requires a city contractor license. A legitimate Denver roofer will have both readily available.

Require general liability (covers property damage) and workers' compensation (covers injuries on your property). Ask for certificates of insurance and call the insurer to verify they're current. Non-negotiable.

After Denver hail events, out-of-state contractors flood the market. Red flags: unmarked trucks, pressure to sign immediately, asking you to sign over your insurance claim, no local office, unusually low bids, offering to waive your deductible (insurance fraud).

1. How long have you operated in Denver? 2. Can you provide 3 local references from the past year? 3. Who will be on my roof — employees or subcontractors? 4. What manufacturer certifications do you hold? 5. What labor warranty do you offer? 6. Will you pull the permit? 7. How do you handle unexpected decking damage?

Get 3+ written quotes. Each should specify: exact materials, layers being removed, decking repair allowance, underlayment type, flashing scope, permit fees, cleanup, and labor warranty duration. Compare what's included, not just the bottom line.
