Certified was recommended to me by a neighbor who was very happy with the job they did. I got three estimates from different companies and Certified’s wasn’t the lowest in cost but they seemed the best in professionalism and quality of the work they would do. I felt that they were very straightforward and honest in answering my questions. They sat down with me and showed me the brochures of the different materials and explained the job in detail and also explained the various options. The man in charge of the job during the installation was also very professional. As far as I could tell they did a great job on the installation – the roof looks great. I would recommend Certified for sure.
