Public Records Check
- License Found As of Jul 10, 2026, the California state licensing board shows an active license for Sergio Lopez Roofing Services: C39 - Roofing 707416. An active license means the state currently authorizes this contractor to do this work. It doesn't speak to the quality of their work or their current insurance. License status can change, so you can confirm it's still active anytime with the California state licensing board.
- Missing Corporation Our automated search didn't find a registered business entity for Sergio Lopez Roofing Services 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 Sergio Lopez Roofing Services's listed address at 3736 Chesapeake Ct, Antioch, CA 94509 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 Sergio Lopez Roofing Services. 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.
