Public Records Check
- Missing License Our automated search didn't find a license on file for BT Roof 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 BT Roof 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.
- Unverified Address BT Roof's listed address at 22721 Alice St, Hayward, CA 94541 appears to be a unconfirmed address. A roofer using a mailbox isn't necessarily a problem, but it can make the company harder to reach or hold accountable. To reach them in person, ask the contractor for a physical address or confirm one directly.
- 3 Credentials BT Roof holds these manufacturer certifications: Johns Manville Summit Club®, Carlisle Perfection Council, NRCA Membership - member since 1994. These show the company met a manufacturer's program requirements and may offer manufacturer-backed warranties, but they aren't independent quality audits. You can confirm current status with the manufacturer.
- Good Ratings Across the platforms we identified for BT Roof (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.
