I met with Tom (owner) after meeting with several other roofing companies. He walked me through the CertainTeed product line and addressed all of my questions. Certified Inc. is a factory certified installer of CertainTeed shingles and is able to provide a very comprehensive warranty. Tom was knowledgeable and hands-on, and his many years of experience in the roofing industry were the primary reasons I chose to go with Certified Inc. After signing the contract I was able to secure an install date within two weeks. The installation of the new roof went smoothly and the team worked efficiently to complete the job in one day. Tarps were used to protect my deck and landscaping. Clean-up of debris was thorough and magnets were used to remove stray nails from the lawn and driveway. The new roof looks great and I would highly recommend Certified Inc.
