It was the coldest, snowiest weekend of the winter when a homeowner found an ice dam on a Saturday afternoon and a soaked bedroom carpet underneath it, with parts of the roof three storeys up. They called DeCarney. That is what January and February 2026 look like here: snow off a roof the next morning, ice dams cleared the same day, one customer's driveway swept clear of everything that came down with it. The rest of the year is roofs going on fast. A June 2026 customer had theirs stripped and replaced inside a single day, and so did one in April 2026 who had planned the job at the end of winter and got it at the start of spring. In September 2025 a 29-year-old roof, steep and complicated, came off and went back on in two days. In January 2026 a house carrying two layers of shingles over original boards rather than plywood had the rotten boards swapped out, the skylight replaced and the leaks around the chimney closed up. Prices matching quotes comes up again and again. A June 2026 customer wrote that the quote matched the final bill exactly; a December 2025 customer said the same about a roof boot repair, with no surprises; an April 2026 one described a thorough, itemised quote and no gotchas at the end. A May 2026 homeowner who asked for an inspection on a 15-year-old roof was told it needed nothing yet. Mario DeCarney is the third generation of his family to roof, and started this Beverly company in 2017. Customers name him, Tony on site, and the crew almost every time they write. The Massachusetts home improvement contractor registration, #203063, is active on the state registry under DeCarney Roofing LLC, and the Better Business Bureau lists the company as accredited with an A+ grade. Google shows 5.0 across 348 ratings and Thumbtack 4.9 across 84, out of 277 reviews going back to 2017. Two practical things. Old decking is where a roof job usually grows: that January 2026 house needed boards replaced once the shingles came off, so ask how board replacement is priced before you sign. And the winter calendar fills with emergency snow and ice work, so if you want a replacement booked in a storm month, get the date in writing. For a straightforward replacement on the North Shore, a leak, an ice dam, or lead flashing a squirrel has chewed through, which was a real May 2026 job, this is an easy call, and the crews finish and clear out quickly. Ask for the written quote with the decking allowance spelled out, and confirm which crew lead will be on your roof.
These guys were true professionals. Mario made the sales process easy and the quote matched the final bill. The price was fantastic. When it came to the installation, Tony was great at communicating with us onsite and making absolutely sure our property was protected during the installation. The crew was highly organized and fast. The work impressed my carpenter who has been renovating section of the exterior....and he is hard to impress. They really did a great job and beyond exceeded my expectations. With a world now full of terrible contractors, working with people who really care and do a top notch job is really refreshing. They went above and beyond on several occasions and you can tell both Mario and Tony (as well as the rest of the crew) care about what they are doing.
We couldn’t have asked for a better experience. Mario never failed to communicate keeping us posted on just when he’d repair our damaged ridge vent. His worker, Tony, was awesome; he got right to work and never stopped until the job was complete. Moreover, Tony left no trace that he was even here. His cleanup was impeccable; my wife and I are very particular about our landscaping. Courtesy for us is key! Mario’s a true gentleman
Great experience from start to finish. Mario answered all our questions regarding materials and ventilation and was in constant contact regarding the schedule. The crew arrived on time, worked quickly and completely stripped and installed our new roof in just one day! They were extremely detail-oriented and cleaned up every last bit of debris from our yard. No pricing surprises at the end. Highly recommend!
Mario and his crew are amazing to work with. Straightforward, timely and caring about our property. Even my neighbors remarked about their skill. I would highly recommend!
Excellent experience with Mario and his crew . Communication was prompt and clear. Work is just as expected and clean up was meticulous.
