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!
