Public Records Check
- Missing License Our automated search didn't find a license on file for Cosmo Roofing with the Virginia 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 Virginia state licensing board or asking the contractor for their license number.
- Missing Corporation Our automated search didn't find a registered business entity for Cosmo Roofing with the Virginia 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 Virginia Secretary of State directly.
- Residential Address Cosmo Roofing's listed address at 1600 S Eads St #Appt 513N, Arlington, VA 22202 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 Cosmo 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 Cosmo Roofing (Google), the blended average is 4.6 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.

Reviewers consistently praise Cosmo Builders for concrete work, roofing, kitchen remodeling, siding, windows, and home extensions. Several customers report professional crews, attention to detail, fair pricing, timely completion, and responsive communication throughout projects. Many reviewers describe the quality of finished work as excellent and express high satisfaction with results. Some customers highlight that the team went above and beyond expectations and completed projects ahead of schedule. However, one reviewer reports a significantly negative experience, stating they provided a 70% down payment for a project that remained incomplete after 4.5 months, requiring them to hire another contractor, and alleging the company threatened legal action against negative reviews and refused to issue a refund.
