NMTI General Contractors

NMTI General Contractors, based in Middleton, works the North Shore doing roof repair and replacement, along with the flashing and gutter work that comes with it. Its Massachusetts Home Improvement Contractor license (197505) is active with the state — a check most competitors in this space skip. The company's reputation is carried almost entirely by roofing calls: a leaky roof caught before it turns into rot, flashing redone around a garage gable, gutters cleaned and rejoined. That same story shows up independently on Angi, on Birdeye, and on a roofing-focused review site, not just one place, which is why the volume matters more than any single number. Two names keep recurring across the reviews people leave — Ramon and Juan — pointing to a small, consistent crew rather than a rotating cast of subcontractors. The pattern holds across a run of reviews stretching from 2021 through 2025. Where the sources don't agree is worth a look before calling: Angi puts NMTI at a flawless 5.0 across 38 reviews, but Google's own users rate it lower, 4.3 across 12. The company's Angi profile also states two different figures for how long it's been in business — 24 years in one section, 28 in another — worth asking about directly. And at least one customer says they contracted with "Tru Blue Construction Inc" rather than NMTI by name, so it's worth confirming which entity is actually named on the license and the contract. For roof repair, replacement, or the gutter and flashing work that goes with it, NMTI is a reasonable call in the Middleton/North Shore area — just get the contracting entity and license number in writing before signing, and ask which of the conflicting business-history figures is the accurate one.
