The Grandville roofing team was professional and efficient. Aaron’s communication was excellent from the moment we got a quote until the roof replacement was finished. We will use this company for any future roofing needs. Highly recommend.

Aaron's professionalism, attention to detail, and "care for the customer" are exemplary. His team did a great job in all aspects: old roof removal, quality implementation of the new shingles, and spotless cleanup. Two thumbs up.
