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.
Norfolk County sees the full range of New England weather — heavy snow loads in winter, nor’easters pushing wind-driven rain, and summer heat that accelerates shingle wear. Our installation process is built around these conditions, not generic specs.

CertainTeed architectural shingles are our go-to for most Norfolk County homes — engineered for high wind resistance, ice dam prevention, and long-term durability in New England weather. Coastal towns like Cohasset and Hingham benefit from higher wind-rated options, while inland communities like Canton and Braintree deal more with heavy snow loads and freeze-thaw cycling. As a CertainTeed Master Craftsman contractor, we help homeowners choose the right shingle line for their home’s specific exposure and conditions.
Missing or curling shingles, granule buildup in your gutters, daylight visible through the attic, and water stains on ceilings are all signs your roof may be failing. If your roof is 20+ years old, a full replacement is usually more cost-effective than ongoing repairs. Many Norfolk County homes built in the 1960s–1980s — especially in Quincy, Braintree, and Weymouth — are now hitting or past replacement age. We provide free inspections and will give you an honest assessment of whether a repair or replacement makes more sense.
Most residential roof replacements take 1–3 days depending on roof size, pitch, and the complexity of the tear-off. In tighter-lot neighborhoods like parts of Quincy, Milton, and Braintree, material staging and debris management require extra coordination to protect landscaping and neighboring properties. We handle all logistics and keep the job site clean throughout the project.
Yes. Every project starts with a free on-site inspection. We assess your roof’s condition, document findings with photos, and provide a detailed proposal that includes material options, scope of work, and transparent pricing. There’s no pressure and no obligation — just a clear picture of what your roof needs.
Look for manufacturer certifications — not just a contractor’s license. A CertainTeed Master Craftsman certification means the installer has been factory-trained and meets strict quality standards. NRCA affiliation shows a commitment to industry best practices. Google Guaranteed status means Google has vetted and background-checked the company. We carry all three, plus BBB A+ accreditation and 150+ five-star reviews.
Most residential roof replacements in Norfolk County fall between $10,000 and $30,000, depending on roof size, pitch, number of layers to remove, and material selection. Larger homes in towns like Wellesley, Brookline, and Needham with steeper pitches or complex rooflines will be on the higher end. We provide free estimates with detailed line-item pricing so there are no surprises.
Yes. Many homes in Milton, Quincy, and Weymouth are 50–80+ years old, and older homes often require additional work that newer roofs don’t — deck repair from hidden rot, ventilation upgrades, and flashing replacements at dormers and chimneys. We inspect thoroughly after tear-off and address any structural issues before installing the new roof system. That’s how you avoid callbacks and premature failures.
