Public Records Check
- Registration-Based Pennsylvania doesn't license roofing contractors; instead it requires a statewide contractor registration. We treat this check as met rather than penalise it, but we haven't independently verified this company's registration - confirm it directly with the state before hiring.
- Missing Corporation Our automated search didn't find a registered business entity for Diversified Roofing Co. with the Pennsylvania 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 Pennsylvania Secretary of State directly.
- Business Address Diversified Roofing Co.'s listed address at 5681 W Lincoln Hwy, Parkesburg, PA 19365 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 Diversified Roofing Co. holds these manufacturer certifications: CertainTeed ShingleMaster Premier. 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 Diversified Roofing Co. (Google, Yelp, the Better Business Bureau, CertainTeed), 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 Diversified Roofing Co.. The more of a company's record you can check, the more informed your hiring decision.

CertainTeed
Customer reviews of this roofing company present sharply divided experiences. Several reviewers report satisfaction with the quality of work, with some describing long-term relationships spanning multiple projects and praising professionalism and integrity. One reviewer notes a technician was "honest, smart, very professional," while another states the company does "the best work" they've encountered. However, one customer expresses significant dissatisfaction, claiming the company failed to replace damaged wood as agreed, caused property damage, left debris on the property, and lacked communication. The company disputes these allegations in their response. Additionally, one reviewer found a roof inspection report unhelpful and felt it was a waste of money, though the company offered a refund and cited travel distance concerns. Overall, reviewers' experiences vary considerably regarding service quality and customer satisfaction.
