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 Drennen Custom Contracting. 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 Drennen Custom Contracting 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.
- Residential Address Drennen Custom Contracting's listed address at 608 E Trilby Rd, Fort Collins, CO 80525 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.
- 1 Credential Drennen Custom Contracting holds these manufacturer certifications: Owens Corning Preferred. 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 Drennen Custom Contracting (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 4/5 public records for Drennen Custom Contracting. The more of a company's record you can check, the more informed your hiring decision.

Reviewers consistently praise the company for radon mitigation and roofing services. Several reviewers report timely arrival, friendly and courteous staff, clean work practices, and competitive pricing. Multiple customers describe satisfaction with the quality of installation and materials. Some reviewers highlight responsive communication and fast quotes. However, one reviewer expressed concerns about the quality of radon system installation, including improper electrical work, unsecured exterior piping, and in-house radon testing practices. That same reviewer noted the company did not accept credit cards. In response, company management acknowledged the complaint and offered to address the issues at no cost. Other reviewers praised the company's honesty in recommending against unnecessary system upgrades and offered free radon testing services.
