How to verify a roofing contractor license in Minnesota

Yes. Minnesota requires every residential roofing contractor to hold a Residential Building Contractor or Residential Roofer license from the Department of Labor and Industry (DLI). Verify at dli.mn.gov and confirm general liability and workers' compensation insurance. Per MN Statute 325E.66, roofers cannot waive or rebate insurance deductibles.

1. Step 01

   Confirm the legal business name

   Ask for the exact name on the license — not a DBA or website brand. The name on the estimate, contract, and license must match.

2. Step 02

   Check the state licensing board

   Search your state's contractor licensing board or Department of Consumer Affairs for the license number. Verify the status is active, unrestricted, and not expired.

3. Step 03

   Verify insurance certificates

   Request current general liability and workers' compensation certificates (COI) issued directly from the carrier — not a screenshot. The certificate should list your project address as certificate holder.

4. Step 04

   Cross-check with the BBB and local courts

   Look for unresolved complaints, judgments, or liens filed against the business. A pattern of complaints is a red flag even if the license is active.

5. Step 05

   Ask for manufacturer certifications

   GAF Master Elite, Owens Corning Platinum, and CertainTeed SELECT ShingleMaster credentials require licensing, insurance, and workmanship history to be verified by the manufacturer.
