Public Records Check
- Missing License Our automated search didn't find a license on file for Gramajo Roofing with the California state licensing board. That doesn't mean the company is unlicensed. A license can be held under a different business name, registered too recently for us to match, or filed in a way our search didn't catch. We recommend confirming directly with the California state licensing board or asking the contractor for their license number.
- Missing Corporation Our automated search didn't find a registered business entity for Gramajo Roofing with the California Secretary of State. That doesn't mean the company isn't legitimate. Many roofers operate legally as sole proprietorships, which don't require registration, and a registered business can be filed under a different name, formed in another state, or created too recently for us to match. To confirm how the business is structured, ask the contractor or search the California Secretary of State directly.
- Residential Address Gramajo Roofing's listed address at 819 San Domingo Dr, Larkfield-Wikiup, CA 95404 appears to be a residential address. This means the company operates from a real, locatable address rather than a mailbox or PO box, which can make it easier to reach them or resolve issues. Many roofers legitimately work from a home address, so this doesn't speak to the quality of their work, license, or insurance.
- 0 Credentials Our automated search didn't find a manufacturer certification for Gramajo Roofing. Many reputable roofers aren't certified by any manufacturer, often by choice, so this isn't a sign of a problem. If a manufacturer-backed warranty matters to you, ask the contractor which certifications they carry.
- Excellent Ratings Across the platforms we identified for Gramajo Roofing (Google, Yelp, the Better Business Bureau), the blended average is 4.8 out of 5, which we label Excellent. This is a plain average of public customer ratings, not a RooferWatch score. A high average reflects past customers' experiences, not a guarantee of yours, so read the underlying reviews and weigh them yourself.
