Public Records Check
- Missing License Our automated search didn't find a license on file for Master Roofing Company 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 Master Roofing Company 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.
- Business Address Master Roofing Company's listed address at 2250 E 12th St, Oakland, CA 94606 appears to be a business 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 Master Roofing Company. 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.
- Good Ratings Across the platforms we identified for Master Roofing Company (Google, Yelp, the Better Business Bureau), the blended average is 4.2 out of 5, which we label Good. This is a plain average of public customer ratings, not a RooferWatch score. A solid average reflects past customers' experiences, not a guarantee of yours, so read the underlying reviews and weigh them yourself.
We verified 2/5 public records for Master Roofing Company. The more of a company's record you can check, the more informed your hiring decision.
