The Certified team did a great job on the roof, and the clean up was excellent. They arrived on time and completed the work in a very timely fashion. We had a difficult time selecting the architectural shingle color/style that would coordinate with our brick, shutters, etc., so having samples of actual shingles to hold up against the house (which the shingle manufacturer strongly recommends), rather than a board showing photos of shingle colors, would have been very helpful (my only suggestion).
