Public Records Check
- Missing License Our automated search didn't find a license on file for GSM Services with the North Carolina 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 North Carolina state licensing board or asking the contractor for their license number.
- Missing Corporation Our automated search didn't find a registered business entity for GSM Services with the North Carolina 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 North Carolina Secretary of State directly.
- Business Address GSM Services's listed address at 407 E Long Ave, Gastonia, NC 28054 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.
- 2 Credentials GSM Services holds these manufacturer certifications: Elevate Licensed Contractor, Johns Manville Summit Club®. 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.
- Excellent Ratings Across the platforms we identified for GSM Services (Google, 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.
We verified 3/5 public records for GSM Services. The more of a company's record you can check, the more informed your hiring decision.
