Merrimack Roofing & Construction Group

Merrimack Roofing & Construction Group works out of 15 Alpine Ln in Chelmsford, and the homeowners who write about it hire it for roofs first and everything else second. Reviewers refer to the company as "MCG" or "Merrimack Construction" and name the owner, Chris, as the person they deal with directly. The most detailed account on file is a 2024 re-roof: the customer had used the company before, went back for a full roof replacement, and describes being told mid-job that the subsurface wood was rotting and the chimneys needed new flashing — with photographs sent to substantiate the added scope before the work went ahead. That one comment does more to show how the company handles a surprise than a dozen shorter ones, and the shorter ones line up with it: a 2024 reviewer says the company redid their roof for an affordable price, and a 2023 customer had a porch roof replaced and was already back in touch about a second project. The work is not confined to roofing. A 2023 reviewer lists home building, remodels, additions, bathrooms, cellars, decks, landscaping and roofs done for their family over a period of years, and another describes a bathroom remodel done well at a good price. Repeat hiring is the recurring theme across the record — several people say plainly that they do not shop anywhere else — and the praise that comes with it is about being on time, on budget, and easy to reach. What is worth weighing before booking is where all of this comes from. Every one of the 13 customer comments is a Google review, and Google publishes a 5-star average from 21 ratings, so no second platform independently checks the picture. The dates also bunch: five comments carry the single date of 27 October 2023 and seven land inside that same week, which is the shape a review push leaves. The newest comment on file is from April 2025. For a Chelmsford-area homeowner wanting a roof replaced by a small, owner-run outfit whose customers keep coming back, this is a reasonable call. Ask for the company's Massachusetts Home Improvement Contractor registration number and current insurance certificate in writing, and ask for two recent roof references you can call — the public record here is a single platform and does not carry that for you.
