We thought we needed a whole new roof. Grandmark came out, inspected everything, and told us it was a minor repair. Saved us thousands and did an excellent job.

Our experience was wonderful. David was professional and provided great insight to the situation with our insurance company. He was on time and efficient. We appreciate his honesty and willingness to work with us! We will use this service again!

I had a wonderful experience working with Grandmark Roofing Company. From beginning to end, everyone I spoke to was kind and helpful. The communication was excellent!! Moises Ortiz and his crew were absolutely wonderful to work with. They were on time, did a thorough job and were meticulous with their clean up. It’s refreshing working with people who care about the customer and enjoy what they do. Thank you Moises and crew!
