Public Records Check
- Locally Regulated New Hampshire doesn't issue a statewide roofing license - roofing is regulated locally through city or county permits, so there is no state license to verify. We don't count this against Denisco Roofing. Confirm any local permit or registration with the city or county where the work will take place.
- Registered Corporation The New Hampshire Secretary of State listed Denisco Roofing as Active when we last checked on Jul 8, 2026, registered since 2015. You can confirm it's still current with the New Hampshire Secretary of State.
- Business Address Denisco Roofing's listed address at 124 Baker St, Manchester, NH 03103 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.
- 1 Credential Denisco Roofing holds these manufacturer certifications: VELUX Certified Installer. 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 Denisco Roofing (Google, Yelp, the Better Business Bureau), the blended average is 4.9 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 5/5 public records for Denisco Roofing. The more of a company's record you can check, the more informed your hiring decision.

The reviewer reports that the crew identified and replaced damaged roof sections and completed both a house and barn roof installation in two days. The reviewer describes the crew as professional, notes they left the jobsite clean, and states satisfaction with the service level and the resulting 30 to 50-year roof lifespan expectation. The reviewer also mentions that neighbors responded positively to the roof's appearance.
