A square is 100 sq ft of roof surface — bigger than the floor plan because of pitch and overhangs.

Ask what Diamond Construction actually gets called for and one answer keeps surfacing: the roof your insurer just told you to replace. Two customers writing in April and June of 2026 described the same experience — a detailed written estimate when other bidders would only talk numbers out loud, and the only contractor in the pile who pointed out the damage might be covered, then carried the claim through a difficult insurer. The company works out of 116 Cochituate Rd in Framingham, and reviewers going back to a 2019 account name John Malo as the owner, and as the person who turns up to quote the job himself. Its Massachusetts home improvement contractor registration, number 176910, is active. Speed is the other thing people keep writing down. A December 2025 customer had old shingles stripped and reinstalled in about a day and a half; a 2020 customer described that same pace on a large two-family roof with skylights. Roofs aren't the whole business — a November 2024 customer had failing cedar shakes replaced with new siding, a 2022 customer got vinyl siding put back after a different contractor tore it off and refused to replace it, and a 2022 Norwood customer had a second-floor addition built. In October 2025 someone wrote that a shower Diamond had installed two years earlier started leaking, they called, and the company came back and fixed it. Now the part to weigh. In July 2025 a one-star reviewer described a small job that went sideways: a basement door threshold replacement that ended with the entire frame removed, water coming in, and five return visits that didn't put it right. That is the sharpest complaint anyone has left, and it isn't old. Two milder ones point the same direction — a 2022 Angi customer who gave two stars with the line "Good work, terrible communicators," and a September 2021 customer who sat six days with a dumpster blocking the driveway after the shingles were done. The platform averages don't agree either. Google sits at 4.3 across 61 ratings and Thumbtack at 4.1 across 56, while Angi and HomeAdvisor both post 4.8. Part of that gap is worth knowing about before you lean on the higher number: sixteen HomeAdvisor reviews all carry a single October 2020 date, and several describe things no Framingham roofer does — a "colourbond" roof, tile and "decorative comp" roofs, and a company "in Sydney." They're a sound call for a storm-damaged roof or a siding replacement, particularly when an insurance claim is in play — that is where eight years of reviews land hardest and most consistently. For a small repair, get the scope written down before work starts, agree who owns the punch list if it isn't right the first time, and pin down the debris haul-away date.
Great experince, helped with full process with insurance and helped with long and difficult insurance provider. Very happy with result
We experienced some interior water damage after a wind/rain storm. We had several contractors provide estimates, though others only did it orally. John provided a detailed written estimate, that independently beat the others. Importantly, he was the only one to point out that it could be covered at least in part, by insurance. (The roof was twenty years old.) Timing was such that we had to wait through more rain and snow, fortunately no further damage, before the weather cleared. We had a deadline, and their office was very helpful in getting us scheduled. It was going to be the only dry weather day of the week. Well, an army of workers showed up early, and a dumpster and protective covers were placed as promised. This crew set up and got to work with no obvious outside direction being required. This was a two unit condo, with a healthy pitch to the roof, as well as porches and added room extensions in the rear. Everyone knew their role, and acted with precision. The entire roof was striped, and additional plywood needing replacement was identified and ordered. The job included applying a waterproof layer, as well as special treatment for edges and valleys, before replacing the shingles, that carry a 50 year guarantee. The job was essentially done in one day, but for some small separate areas of trim. These were polished off on the next sunny morning. Clean up was done with care, second only to the overall sense of safety that was maintained throughout the job. The roof looks great and we couldn't be happier. We may well have been their first job in Needham, but there were no delaying issues, and I am glad to give them my highest recommendation.
I highly recommend Diamond Construction; the bathroom they renovated for me turned out fantastic. I was more than satisfied with the result. I must also mention their excellent customer service. All my questions and concerns were addressed promptly. In short, a great company with excellent prices.
John and his team did a great job on replacing the old shingles on my roof. The communication was great - they provided detailed information and answered all my questions promptly. The crew worked very hard to accomplish the removal and installation in about one and half days. I have already recommended Diamond Construction to my friends and will consider them for my future projects.
i hired diamond constuction a couple years ago for a total rehab project, they did all the work in a prompt time and communicated well, a few months ago i had a problem with the shower leaking they installed 2 yrs ago, i called and without any hesitation jenn & john assured me they would take care of the problem and they did. good companys stand behind their work and they delivered, i would recommend them highly
