Public Records Check
- License Found We found a license number on file for One Roofing: 1084379, but haven't confirmed its current status directly with the California state licensing board. We recommend verifying it's active and in good standing with the California state licensing board before hiring.
- Missing Corporation Our automated search didn't find a registered business entity for One 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.
- Mailbox (CMRA) One Roofing's listed address at 1160 Battery St #Ste 100, San Francisco, CA 94111 appears to be a mailbox (CMRA) 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.
- 0 Credentials Our automated search didn't find a manufacturer certification for One 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 One Roofing (Google, Yelp, the Better Business Bureau), the blended average is 5.0 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.
