NH Grand Roofs describes itself as a Londonderry, New Hampshire roofing company doing residential and commercial roof replacement across southern and central New Hampshire. The site says the business is family owned and operated by Chris Perfetto, who does the estimating and is on site for projects, with Christy Perfetto running customer service and back office. It says Chris moved from selling roofing materials to contractors into doing the work himself, with over 20 years of industry experience. BBB shows the company as accredited since 2018 with an A+ rating and a 2015 business start date. A 2024 customer said Chris, Christy and their crew installed a new roof and two bathroom vents, and that it was all done in one day and cleaned up. A 2024 reviewer wrote that the crew arrived early, everything was completed and cleaned up by end of day, and their leaky roof was now water tight. In a 2022 review, a customer said the company protected their lawn, shrubs and pool with huge tarps and replaced the roof in two full days. A 2023 customer said the job was scheduled around a tight schedule they had for out-of-town visitors, and that the yard was spotless when they left. A 2024 reviewer said Chris completed their roof and described the company as delivering on time and within budget. A 2023 commenter on r/newhampshire called it great work at reasonable prices. One scheduling condition comes from a 2024 customer: the company can only plan one to a few days in advance. That customer said they were kept updated during the roof replacement with photos and texts throughout the day, and that new plywood was an additional cost they had expected.
“is an awesome company - great work, reasonable prices, really nice people.”
We highly recommend NH Grand Roofs and couldn't be happier with their work of replacing our roof! The materials they used were all high quality. From start to finish, every detail was explained and carefully executed. The crew worked so efficiently and their years of experience was evident, from the quality of the work. Thank you for taking such good care of our home.
What a great and stress-free experience having our new roof installed by Chris, Christy and their awesome crew! They were very professional, explained the entire process, answered all our questions and assisted us in selecting the best shingle color to match our house. They also installed 2 bathroom vents and now our bathrooms do not fog up after a shower. It was all done in one day and everything nicely was cleaned up. The quality of the materials, workmanship and warranty are awesome! If you are in need of a new roof, I highly recommend Chris, Christy and the team from NH Grand Roofs.
Chris completed our roof this past April and after having finished a career working with heavy industrial contractors I am very familiar with what makes a good one. NH Grand Roofs is a great contractor who delivers on what they say, they do it on time and within budget. Everything you want in a great contractor. Chris and his wife Christy have this business running like a well oiled machine and I cannot recommend them highly enough for your next roofing project.
We had a WONDERFUL experience working with NH Grand Roofs. They were extremely responsive, timely, and reasonably priced. Their crew arrived early and worked hard until the job was done. Everything was completed and cleaned up by end of day and our leaky roof is now water tight! We are extremely grateful and would highly recommend them to anyone.
From start to finish (estimate to roof replacement) Christy & Chris and team were outstanding. Professional, but personable and a pleasure to chat with. Explained everything from start to finish, kept us updated during the roof replacement as well, with photos and texts throughout the day. We also needed new plywood, but this wasn't a surprise to us, and we were kind of expecting it (additional cost). Would recommend HIGHLY! Be aware that they can only plan 1 to a few days in advance. So please be kind and understanding that contractors who work outside have Mother Nature to contend with and generally you ONLY have short notice of when they are coming. Be kind to outside contractors :)
