2026 Update - I have now worked with G&S on 3 major projects and absolutely recommend them for just…read moreabout anything. I found them when I was looking for gutter installation work and was so impressed that I had them replace the entire roof on my house sized barn (~2100 sq ft) with Owens Corning along with significant rehabilitation work to the substrate. Most recently, they built a composite deck on my property. The price was very good on all occasions and change orders handled exceptionally well. It seems all too rare these days that you find a contractor that is reliable, competent and takes real pride in their work but that's exactly what you're getting here. These are skilled and honest professionals who do excellent work and stand behind both the process and the finished product. I have no doubt that we will work together again and I hope they know how much I appreciate the care that they've taken with my unique and often complicated property!

Tony is a reliable, friendly guy, and it was a pleasure doing business with him.

I discovered a leak in the ceiling of my 1st-floor half bath, and traced that all the way up…read morethrough my office to the attic. It took a while for me, as a first-time homeowner, to understand that this meant I had a leak in the roof, because I thought it might somehow be a plumbing issue (it was a leak down the bathroom's exhaust vent pipe). The plumber said roofer. I found Manny because I was looking for someone to repair my front porch steps, and given that he was also a roofer, I asked him to give his opinion on what I hoped was a minor issue that could just be repaired, but it turns out that it needed a whole new roof, because the flashing around the pipe was bad, and with further inspection, turned out to be missing shingles, on top of THREE layers of roofing that they'd just kept putting more on. Manny made it easy to coordinate with the insurance company, and what a relief that they agreed to pay for the majority of the roof (but not the tower, which was actually the portion that was in the worst condition, but it wasn't storm damaged, just old). But his help in coordinating made it possible to get it all done, including repairing my front steps, because the cost would have been overwhelming without the insurance part of the equation. The workers were all so kind and helpful, particularly in maneuvering in the tight spaces that is my yard/driveway to get the trash to the curb on trash day around the dumpster in the driveway. Thankfully this work was completed in the winter so no worries about crushing blooms in my front garden, but I also appreciated how they put down tarps over all the plants to protect them, used nets to slide debris into the dumpster, and came back around to clean up after--including using a magnet to catch stray nails. I did unfortunately lose a blueberry bush and I'm a little worried about my blackberry canes, but overall they did their best and while I'd have preferred leaving my leaf mulch down, there's no way to distinguish between the leaf mulch and trash, so you shrug and deal with it. I'm sure the perennials will be fine come spring. As you can see from the pictures, my 1886 Victorian has quite a complicated roofline, and they were able to preserve the profile of the roof, put everything back where it ought to go, and then they'll be coming back in a couple of weeks to patch up the interior places where I originally realized there was damage.

I felt badly when I had to tell them not to come out a few hours before because our original contractor, who let us down again over and over, had promised he would show up. They were very gracious and accepted my apologies which definitely gives them 5 star on customer services ratings! I wish that I could have used them but there were circumstances beyond my control! I appreciate the opportunity they gave me; their work I saw in pictures was amazing!
