I had a great experience with Greater Boston Roofing! I recently had them do a major roof replacement on an apartment building I own in Manchester, NH. It was a very complicated job, with many different roof planes with varying layers of old roof materials to remove, including 10s of thousands of pounds of slate! I also had some leaking and water damage around some of the chimneys, which they removed and now I am happy to say there’s no more water damage. Considering the very challenging scope of work, they did an outstanding job. From the beginning, their quote was extremely detailed, transparent and fairly priced; in fact it was the lowest quote I got amongst the comparable companies I spoke with. The roofing materials they use are top of the line Owens Cornings products. They promised me a very fast turnaround time to complete the job, which they not only delivered on, but exceeded. They did the job in 4 very efficient days, where their crew worked their tails off from sunup to sundown, on freezing days in the middle of February no less. They are a well-oiled machine, and clearly have good systems in place. The supervisors Bill and Andrew excelled in their communication. Same with the owner, Alex, who was a pleasure to work with and makes it a top priority to accommodate the client and deliver on what he promises. The end result is a roof that now only looks immaculate but will hopefully yield decades of peace of mind for my cherished rental property. I would highly recommend GBR to anyone looking for a great roof replacement experience, top to bottom, at a reasonable price!
