the Department of Labor and Industry (DLI) is what licenses Minnesota residential contractors, roofers included, and its register of those licenses is public Official lookup: Minnesota DLI license lookup.
- The registry name, the contract name and the truck lettering should all agree; the status should be active.
- Search the registry by number, then by name, because spellings differ between sources.
- Have the insurer or agent send the certificate of insurance to you, since a license says nothing about coverage.
- Look at the expiration date and compare it with the dates in your contract.
Registry last checked October 2026; the license on file shows an expiration of 2028-03-31. A badge covers the license match only, not insurance or workmanship.
