My wife and and I used AK Gatsios to completely remove and replace our house's roof, including the plywood underneath. We're extremely happy with the results and wholeheartedly recommend this contractor. The owner, Alkis, is a GAF "master elite" roofer, which qualified us for their wonderful Golden Pledge warranty, 50 years on materials and 25 years on labor! This also means he used all quality GAF materials and complied with strict golden pledge specifications. His crew of 10 were very hard working and completed the bulk of the work in 1 day, coming back just to finish up details. Alkis wanted to make sure we'd be completely satisfied with the results. He's very pleasant to work with, gave us a great price, and proved to be extremely honest and trustworthy. We're planning on hiring him to finish our attic next.
