            We used C3 American Exteriors for our new roof, which was installed in October. I cannot say enough good things about this company. From the beginning they were professional, prompt, and thorough. Our sales rep, Gary was friendly and very knowledgeable. He made sure all of our expectations were met throughout the whole process. Our new roof looks beautiful. It was a smooth process from start to finish! I highly reccomend C3 American Exteriors!

            The roof looks better than we could imagine. Mike Bucher and the team were fast and efficient with their delivery of our new roof. Mike even went above and beyond with some added bonuses that really proves C3 is a superior roofing company.
