Public Records Check
- Locally Regulated Colorado 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 Core Roofing Systems. Confirm any local permit or registration with the city or county where the work will take place.
- Missing Corporation Our automated search didn't find a registered business entity for Core Roofing Systems with the Colorado 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 Colorado Secretary of State directly.
- Business Address Core Roofing Systems's listed address at 4049 St Paul St, Denver, CO 80216 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 Core Roofing Systems holds these manufacturer certifications: NRCA Membership - member since 2014. 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 Core Roofing Systems (Google, Yelp, the Better Business Bureau), 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.
We verified 4/5 public records for Core Roofing Systems. The more of a company's record you can check, the more informed your hiring decision.

Yelp
Customer reviews of Core Contractors are predominantly positive. Several reviewers praise the team's knowledge, professionalism, and responsiveness, with specific staff members like David Marsh, Briana Nelson, Yisa Kennedy, Will Cunningham, Paul, and Jeremy receiving individual recognition. Reviewers report satisfaction with roof replacements, repairs, gutter work, solar panel installation, and insulation services. Many customers describe timely inspections, detailed estimates, on-time appointments, and work completed within budget. Some reviewers note the company helped navigate insurance claims, with one customer reporting friends received significantly higher insurance payouts after Core's involvement. However, two negative reviews express concerns: one customer felt charged excessive trip fees for additional work not identified initially, and another reports the company has not accepted responsibility for damage to plumbing caused during roof replacement, despite seven weeks passing.
