How to check Thiele Roofing & Construction on the Wisconsin record
Wisconsin roofing-license requirements are not yet covered by our verification program — confirm licensing and insurance with your city or county building department
- The registry name, the contract name and the truck lettering should all agree; the status should be active.
- Ask for a certificate of insurance sent straight from the insurer. A registry listing does not prove coverage.
- Start the lookup with the license number; use the business name only if the number fails.
- Look at the expiration date and compare it with the dates in your contract.
