Expert roofing for Plymouth County homeowners — from Norwell and Marshfield to Duxbury and Scituate. Google Guaranteed. CertainTeed Master Craftsman certified. 150+ five-star reviews.






Plymouth County stretches from coastal towns like Scituate, Marshfield, and Duxbury — where salt air, nor’easters, and ocean-driven wind batter roofs year-round — to more sheltered inland communities like Hanover, Rockland, and Whitman. Whether your home sits a quarter-mile from the ocean or ten miles inland, the roofing system needs to be built for the conditions it actually faces.

Posted on Curtis MatthewsTrustindex verifies that the original source of the review is Google. Our house in Danvers needed new siding and trim, and this was not an easy project. There were surprises once the old siding came off, but John walked us through everything calmly and professionally. The final result looks incredible and feels built to last.Posted on Joshua DixTrustindex verifies that the original source of the review is Google. Very professional operation. Clear contract, good communication, and high-quality work. Our new roof looks great and the flashing details are far better than what we had before.Posted on Imani YussifTrustindex verifies that the original source of the review is Google. We’re in Marblehead, close to the water, and needed exterior work that could actually stand up to the elements. D&G Exteriors replaced our roof and trim, and the difference in quality compared to previous work on the house is obvious.Posted on Miguel RojasTrustindex verifies that the original source of the review is Google.

We live right on the ocean in Gloucester, and the weather absolutely beats up our house — constant wind, salt spray, storms rolling in off the water. After years of patching things, we finally decided to hire D&G Exteriors for a full roof replacement and some badly needed trim repairs. I’m so glad we did. Working on a house this close to the shoreline is no simple job. The crew had to deal with strong winds almost every day, and once they pulled the old shingles off, we found sections of the roof deck that were softened from years of salt exposure. John didn’t overreact or try to turn it into a huge problem — he showed us the damage, explained what needed to be replaced, and kept everything straightforward and fair. Despite the tough conditions, the team worked cleanly and efficiently. You could tell they were used to handling challenging environments. They installed new CertainTeed shingles, repaired the compromised areas, and replaced all the rotten fascia and trim with PVC so we won’t have to worry about it again. The house looks incredible now — sharper lines, cleaner edges, and a roof that finally feels like it can handle a real coastal storm. The best part was how professional the whole process was. They kept the site tidy even with the wind constantly blowing debris around, communicated every day, and never left us guessing about what was happening next. If you live anywhere near the water and need roofing or exterior work, D&G Exteriors is absolutely the company you want. Five stars, without hesitation.Posted on brian haskinsTrustindex verifies that the original source of the review is Google. We’re in Ipswich, and hired D&G Exteriors to replace our roof and correct a long-standing issue around a valley that had leaked during heavy rain for years. Previous repairs never fully solved it. John identified the problem immediately, reworked the flashing detail, and rebuilt that section properly instead of just patching it again. Since the replacement, we’ve been through multiple hard storms with zero issues. The roof looks great, but more importantly, the problem is finally gone. Very happy with the work and the attention to detail.
Plymouth County’s coastal exposure means roofs take more abuse than most — salt-laden wind, horizontal rain during nor’easters, and rapid freeze-thaw cycles that punish every seam and transition. Our installation process accounts for these conditions at every step, not just the shingle layer.

CertainTeed architectural shingles are our primary recommendation for Plymouth County — specifically their high wind-rated lines for coastal towns like Scituate, Marshfield, and Duxbury. Homes closer to the coast need shingles rated for 130+ mph wind uplift resistance. Inland communities like Hanover and Whitman have more flexibility with standard architectural shingles. As a CertainTeed Master Craftsman contractor, we match the right product to your home’s actual exposure.
Curling or lifting shingles, granule loss in your gutters, daylight through the attic, and water stains on interior ceilings are the most common warning signs. Coastal Plymouth County homes tend to show wear faster due to salt air and wind exposure — a roof that might last 25 years inland may need attention at 18–20 years near the coast. We provide free inspections and will tell you honestly whether a targeted repair or a full replacement makes more financial sense.
Most residential replacements take 1–3 days depending on roof size, pitch, and tear-off complexity. In seasonal coastal towns like Duxbury and Marshfield, scheduling around weather windows and summer traffic patterns is part of the job. We coordinate logistics in advance so materials are staged, crews are confirmed, and the project stays on timeline.
Yes. Every project begins with a free on-site inspection. We walk the roof, document the condition with photos, and prepare a detailed proposal that includes material options, full scope of work, and transparent pricing. No pressure, no obligation — just a clear picture of what your home needs.
Yes. We’re a CertainTeed Master Craftsman contractor, NRCA affiliated, Google Guaranteed, and BBB A+ accredited. Coastal roofing requires more than just standard installation — proper wind-rated shingle selection, enhanced flashing at transitions, and full ice & water shield coverage are all critical in towns exposed to ocean weather. We’re trained and certified for exactly this kind of work.
Most residential roof replacements in Plymouth County range from $10,000 to $30,000, depending on roof size, pitch, material choice, and the extent of any deck repairs needed after tear-off. Coastal homes with steeper pitches or significant wind damage history tend to fall on the higher end. We provide line-item estimates so you know exactly what you’re paying for.
Yes. Plymouth County’s coastal communities — Scituate, Marshfield, Duxbury in particular — take direct hits from nor’easters and winter storms. We handle emergency tarping, insurance documentation, and full storm damage repairs. If your roof has been damaged, we’ll assess the scope, document everything your insurance company needs, and manage the repair or replacement from start to finish.
