there is no roofing-specific license in Iowa — contractors carry a state contractor registration, and permits are handled locally by city or county
- Have the insurer or agent send the certificate of insurance to you, since a license says nothing about coverage.
- Go to the registry and search by license number first, business name second.
- Write down the expiry and make sure it outlasts the job.
- The registry name, the contract name and the truck lettering should all agree; the status should be active.
