Checking Guarantee Roofing & Siding against the Iowa record
what Iowa requires is state contractor registration, not a roofing-specific license; permit requirements come from your city or county
- Look at the expiration date and compare it with the dates in your contract.
- Open the registry and search by license number first, business name second.
- Ask for a certificate of insurance sent straight from the insurer. A registry listing does not prove coverage.
- Match the name, the city and the status. The record should read active or in good standing.
