Tom at Certified was professional and helpful. He gave us the time and attention we needed. Job was done well and looks great. Price was significantly below 3 other roofers. We did find 2 nails in the yard after they were done, but no other complaints.

It was a pleasure working with Certified Inc. I obtained quotes from several companies, but Tom's professionalism and promptness in answering all my questions and providing details on the job, made Certified Inc stand out from the competitors. The work performed was of high quality, the crew was very professional and courteous. They cleaned up after the work was finished. Strongly recommend them and will not hesitate to use them in the future.
