We needed a roof replacement for a colonial style home with an extension and porch. Tom Keen of Certified Incorporated was most helpful selecting the color and kind of shingle. The top-end product that was used was the right choice. We subsequently needed two skylights replaced, which Certified Inc. handled, as well as a follow-up leak that was coming from the siding (not the roof). They were able to expertly identify and repair the leak. We are very satisfied with their work and the excellent crew that completed the work as promised and on time.

I needed to have the roof of my four-bedroom single family home replaced with new shingles, including the flat sections of the house. Certified Incorporated did the work for me. I have nothing to complain about their service. They came promptly on the appointed date and got right to work. They tore down the old roofing material and did the repairs on the sheathings before laying down the new shingles. They finished the whole roof in two days, and up to this point, I haven't noticed any leaks. They made sure that everything was in order before they left. They did a great job, and I recommend their work.
