- Business Address Grandmark Service Company's listed address at 4545 N Brawley Ave #Ste 105, Fresno, CA 93722 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.

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.

Yelp
According to the reviewer, Grandmark provided a roof replacement estimate of $52,000 at 14% interest, while Pristine Roofing quoted $32,000 for the same materials with a 3.9% loan rate. The reviewer characterizes Grandmark's pricing as significantly higher and describes their interest rates as inflated compared to competitors. The reviewer notes that Pristine Roofing's "Go Green" certification resulted in lower loan interest rates. Based on this single customer's experience, Grandmark's pricing appears substantially more expensive than at least one alternative roofing company for comparable work.
