GN Exteriors - Roofers in Braintree

GN Exteriors, run out of Braintree by owner Manny, has built one of the deepest and most consistent records in this corpus — 178 reviews since 2020, all five stars, with 26 more landing in just the last six months and zero negative accounts anywhere in that span. The company holds an active Massachusetts home improvement contractor registration, and BBB has it at an A+, accredited rating. The range of work is wide, but the throughline is speed and communication under pressure. A 2026 review described a plumbing vent with a damaged seal: Manny called back within an hour of being contacted and had a crew member assessing the problem that same day. Another 2026 account described a three-season porch badly damaged in a windstorm, where the crew put together a repair plan on the spot and started immediately, covering both the roof and the interior wall damage. Storm and emergency calls come up again and again — ice dam removal, nor'easter damage, a shattered skylight fixed the day after a fallen tree branch — and reviewers consistently note a same-day or next-day response. The bigger jobs show real range too. A 2026 review described an extensive, multi-contractor search that ended with GN taking on a three-story, 19th-century Victorian split into seven oceanfront condo units — work the reviewer called truly challenging. A 2025 review described an 11-unit condo association re-roof in Jamaica Plain that spanned three different roofing materials — asphalt shingle, rubber, and slate — on one building. And a 2023 review described a 1905 house with a steep, high main roof plus four smaller roof sections and three layers of old material to strip, a job the crew worked steadily for two full days to get through. Beyond roofs, siding and gutters are a real second leg of the business — reviews describe full siding replacements, a gutter system resized after the original builder under-specified it for the house, and repeat customers who've had GN back for multiple projects over several years. Manny himself comes up in nearly every account: inspecting jobs personally, explaining costs and options upfront, and following up after the work is done. Get the full scope, materials, and timeline spelled out in the written estimate before work starts — standard practice for a project at this scale.
