Excellent! First finding a company that would replace flat roofs was difficult enough, most would charge corporate prices because it was a difficult job, A & D not only took on the job but kept the price very reasonable. Since it was such a large job a few issues arose. They took every step possible to make sure that we were completely happy with the process and especially the end result. We would also like to make sure to point out that Dustin and Heidi went above and beyond with their customer service! Over the last few years we have, between 3 generations, dealt with several roofing companies, and A&D is a model of how a company should be run from customer service to finished product.
