Verified record
Merrimack Roofing & Construction Group, working out of Chelmsford, is built around two things: full roof jobs and the bigger construction projects — additions, remodels, decks — that come with owning a home for decades. Every review on file, going back to 2023, describes the same person running the show: an owner named Chris, credited by name for keeping jobs on schedule and on budget. The written record runs 2023 through early 2025 — 13 Google reviews, all five stars, no negatives on file. A late-2024 review describes a re-roof where the crew found rotting subsurface wood and failing chimney flashing mid-job, documented it with photos before doing the extra work, and charged a reasonable price for it. A 2023 review from a longtime client lists a real range of projects handled over the years — home building, additions, bathrooms, cellars, decks, landscaping, and roofing — all credited to Chris personally as the reason they keep coming back. Other specific jobs from the 2023–2024 record include a porch roof replacement, with the customer already back in touch for a second project, and a bathroom remodel finished at a price the customer called fair. There's nothing critical in the written record to raise before calling. Anyone hiring them for a re-roof or a larger remodel can point to a genuine multi-year track record with the same owner still doing the work — worth confirming current availability and pricing directly, since the newest review on file is from spring 2025.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Merrimack Roofing & Construction Group. Use it to sanity-check bids, then get the real number in writing.
A square is 100 sq ft of roof surface — bigger than the floor plan because of pitch and overhangs.

Amazing work!! Will definitely recommend MCG to family & friends!
Have used Merrimack in the past for many different projects and went back for a re-roof job. During the work they informed me of additional work needed (subsurface replacement for rotting wood, new flashing around chimneys) and sent pictures to substantiate. Good communication, quality work and reasonable price.
Amazing team, they really care about the client and communication was given every step of the way. Definitely will recommend 💯
Punctual and very professional work, 100% recommended
