They are top notch! they did my residential roof with the highest quality. I researched over 10 other roofers, none even compare in terms of openness of the work they will be doing, doing what it takes to complete the job on time even when thrown surprises by the materials distributer, and follow up years later when I had a leak that turned out to be chimney cap and not roof material related. You will not find a better vendor for a quality roof.
