Great work, easy engagement.. from a fast accurate quote, to scheduling, to keeping in touch as we neared install date.. the day of, they showed up as scheduled and went right to work.. their team has their system down pat.. setup, rip, clean up, surface prepare, final shingles, final cleanup.. small house.. one day to complete all.. neighbor was so impressed, they had them do their house.. I watched them do the same process.. done in a day.. both houses look great.. I would recommend them for anyones house..

Rob and team did an amazing job on our commercial building in Nashua. As an old Factory, built before the turn of the century, we've had a host of problems over the years with the old flat roofs. From the first appointment, Rob and crew were on top of everything - showing up when they said they would, going above and beyond to work with us on the options we needed, and working quickly. We were also impressed that during final inspection when we noticed one minor thing on a vent boot that could easily have been fixed with some caulk, they skipped taking that shortcut and instead did the extra work to redo the larger area around it and ensure we got the best result.
100% quality, delivery, timeliness, and professionalism. Rob and his crew did a phenomenal job on my house. He gave me an upfront estimate and advised that if there was any need for replacement of plywood that there would be an additional cost. The roof plywood had delaminated significantly in some areas and it was very evident that it needed replacement. The crew operated safely and with the experience that comes from the knowledge of their leadership under Rob. Cleanup was done including all debris removal and a magnetic sweep to be sure errant nails wouldn’t find their way into my vehicle. I highly recommend GSR. I will refer when given the opportunity.
