The word that keeps showing up across nearly a decade of reviews for this Boston flat-roof contractor is competitive: homeowners who priced out multiple companies keep landing on Denis Tchernov's team as the reasonable, non-pushy option. In a March 2026 review, a homeowner whose master bedroom started leaking after a heavy-snow winter says other companies quoted unbelievably high prices and used pressure tactics, while Denis offered a fair estimate instead. Its Massachusetts home improvement contractor registration is active, verified against the state registry. The company works mainly in flat and low-slope roofing — PVC, TPO, EPDM and rubber membrane — plus rooftop decks. In a July 2024 review, Denis diagnosed a rubber-roof leak as just a bad vent pipe rather than pushing a full roof replacement, and fixed it with a pipe swap and an elbow cap. A June 2024 review describes him sending a customer to a different contractor once a free inspection turned up a siding problem, not a roofing one. Longer-running jobs hold up over time: a 2021 review describes a PVC roof installed in 2014 that still looked new seven years later, and a 2023 review from a customer whose flat and sloped roofs were replaced thirteen years earlier describes matching new copper drip edge to a historic home's existing trim. Rooftop deck work shows up too — a 2023 review describes tearing off a decaying wood deck on a Brookline building and rebuilding it as a walkable PVC-membrane deck with composite railings. Not every account is positive: a 2023 one-star review describes Dennis Tchernov coming to look at a job, promising quotes, then going silent for three weeks, leaving the customer to hire someone else. The company's own website is inconsistent about how long it's been operating — its About page says 'over 20 years' while its homepage banner claims 'More Than 24 Years,' and BBB lists 25 — worth a quick question if the company's history matters to you. It carries a BBB A+ rating and has been BBB-accredited since 2022. For a flat, low-slope, or membrane roof around Boston, Brookline, Newton, or Wellesley — a replacement, a stubborn leak, or a rooftop deck — reviewers describe getting a straight assessment rather than an upsell; get a firm timeline in writing given the one account of a follow-up that never came.
Great service and very professional team. Everything was handled quickly without feeling rushed. I’m very satisfied with the overall experience.
I recently had a flat roof replace done and chose a company called ID Flat Roof after consulting with Denise. This year, we had an unusually heavy amount of snow, which caused a serious leak in our master bedroom. The situation was urgent, so I had to act quickly. I received estimates from several companies. Some of them quoted unbelievably high prices, and a few even used intimidating language, suggesting that if I didn’t choose them, the leak could happen again. It made the decision quite stressful. However, Denise and his team at ID Flat Roof stood out. They offered a fair and reasonable estimate, completed the work quickly within the timeframe I needed, and most importantly, took the time to explain everything in detail, which gave me real peace of mind. They also provided a solid warranty, which made me feel even more confident in their work. If you need any roof work done, I highly recommend this company. They are professional, trustworthy, and truly care about their customers.
Denis and ID roof replaced a flat rubber roof on my JP triple decker with a White PVC roof. From communication to completion everything was excellent with Denis. I had three well regarded companies come out and Denis‘s price was the most competitive. I had great communication by phone call and text message nearly every day while they were working on the job. I was especially impressed with the drone photos and videos before and after so that I did not have to go up onto the roof to inspect the work when there was an unexpected issue with the Wood decking. Once they remove the old roof Denis was quick to propose a solution and keep things on track. As the manager of Arborview Realty, I would not hesitate to recommend ID Roofing to our clients in the future everything Denis said he would do. He did including permits and a paid receipt at the end. Great work.
Excellent communication with homeowner Showed up on time, kept me updated on all aspects of job. This is a very rare work ethic for contractors nowadays. Also very knowledgeable about his craft and explained the job about all the details.
I highly recommend ID Flatroof for Roof repair and replacement; Denis and his team provided a prompt and professional scope of work from the start. As The team came in they were very communicative and responsive; they provided assessments of issues and best approach as needed. They worked hard and completed the project quickly and efficiently. We received pictures of the work and video, they removed all debris and were respectful of neighbor's and property; it's tight quarters in the city! Town Inspection was passed and work completed without issue. Very pleased with the results, never looked better with new bright flat roof and skylight and best of all...no leaks thereafter with the rainstorms this summer!
