GN Exteriors

GN Exteriors works out of Randolph, taking on roof replacements and repairs — rubber and metal roofs show up again and again in the reviews — along with the siding and gutter work that often rides along with a roof job. The name that keeps surfacing is Manny, the owner, who reviewers describe as the one who comes out to look at the job and price it before a crew ever gets scheduled. The pattern holds up at scale. Google shows a 5.0-star average across 86 ratings, and in the past six months the company picked up fifteen more reviews without a single negative one. The specifics repeat: a roof leak called in one morning got fixed that same day; a damaged plumbing-vent seal was inspected and dispatched within the hour, with the repair finished the next day; and a roof battered by a nor'easter got a same-day visit, a full inspection, and a quote before any work began. Pricing comes up as competitive rather than rock-bottom — one customer who shopped several vendors said the quote landed right in line with the others. On a large siding-and-gutter job on a tight lot, one reviewer described the crew cleaning down to the last piece of sawdust when they finished, and when a small issue turned up after another job, the team came back and fixed it without an argument. Change orders and add-on work mid-project get handled without friction too, according to a recent review. None of this is new — the company has built roughly 76 reviews across six sites since 2020, so the current run looks like the norm, not a lucky stretch. One thing worth double-checking: a LinkedIn listing puts the business in Braintree, while its name and multiple customer reviews place it in Randolph — with at least one job done as far out as Weymouth. It's not a mark against the work, just a detail worth confirming before you assume which office or crew territory applies to your address. For a roof job, or the gutters and siding that often come with one, the license is active and the BBB rating is an A+, backed by a review volume deep enough to trust. Before signing anything, get the written estimate the way Manny is described giving most customers, and settle the Braintree-versus-Randolph question so you know who's actually showing up.
