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

D&G Exteriors is a Beverly, MA outfit built around the roof-and-siding call: the reviews describe leak chases, storm patches, full re-roofs, and Hardie-board siding jobs up and down the North Shore, from Salem to Ipswich to Boxford. The same name shows up job after job — John, who walks homeowners through the options on site. Across 161 Google ratings the average sits at 5 stars, with a matching 5.0 from 15 Thumbtack reviews; the company has 156 reviews on file since 2023 and none negative in the last six months. What keeps recurring in the written accounts is diagnosis before demolition. One Salem homeowner had a roof that leaked every time it rained from the east; John found the actual problem and fixed just that section rather than pushing a full replacement. Storm-damaged siding gets matched and patched so the repair disappears into the existing wall. On older houses — a 100-year-old Ipswich property, a Boxford farmhouse overdue for a roof by years — reviewers describe trim rebuilt and flashing reworked in ways that respect the original structure. The bigger jobs follow a similar shape: full exterior overhauls bundling roofing, siding, and windows, sometimes phased across a budget (roof and water damage first, siding and windows months later), and deck rebuilds where a soft, unsafe structure gets torn out and replaced with composite decking, occasionally regraded underneath to fix drainage. Homeowners who shopped around — one interviewed five contractors before choosing D&G for a fourteen-window job in Marblehead, another talked to six or seven companies before a full remodel in Hamilton — cite the same reason: John measured and explained rather than just quoting a number. The company's Massachusetts home improvement contractor registration is active, and it describes itself as a CertainTeed 5-Star Contractor. Its own site lists fencing and exterior painting alongside its roofing, siding, window, deck, and gutter work, though the written reviews concentrate almost entirely on roofs, siding, windows, and decks — worth asking about directly if a project needs the painting or fencing side of the business. This is a solid call for a North Shore roof, siding, or window project, especially an older or trickier house where a contractor needs to work around existing conditions rather than just replace everything. Confirm current scheduling and get any phased-project plan in writing if the job is a bigger one.
We put a standing seam metal roof on our Salem colonial and it's the best decision we've made on this house. Looks incredible, snow slides right off, and we're done thinking about our roof for the rest of the time we live here. John was great about explaining the differences between metal and shingles without pushing us either way. Really happy with D&G Exteriors.
We had a section of our roof that was leaking every time it rained hard from the east. John came out, found the problem, and had it repaired within a week. No pressure to replace the whole roof, just fixed what needed fixing. Leak is gone. Really appreciated the honest approach.
Called them about some siding that blew off during a storm. They came out fast, matched the existing material, and patched it so you can't even tell where the damage was. Quick, professional, reasonably priced. Exactly what you want in that situation.
Needed a deck torn down and rebuilt in Manchester-by-the-Sea. The old one was unsafe. Soft boards, wobbly posts, the whole thing moved when you walked on it. D&G built a new composite deck that's solid, looks clean, and should last a long time without the maintenance headaches we had with the old pressure treated wood. They also adjusted the layout so we actually have room for a table and chairs now, which the old deck never really allowed. Smart design and solid execution.
What an awesome job D&G did on our roof. The work was top of the line. They were done in 1 day even though there was a lot extra work that had to be done before the roof could be replaced. I would not hesitate to hire the group of workers again. They have a great team working with them
