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.
We design and build roofs to age well over decades. That means going beyond shingles — inspecting what’s underneath, repairing what’s compromised, and installing every layer to manufacturer specs.

CertainTeed architectural shingles are the top choice for Middlesex County — engineered for freeze-thaw cycles, heavy snow loads, and high winds. We install the full CertainTeed line including Landmark and Landmark Pro. As a CertainTeed Master Craftsman, our installation qualifies your roof for the strongest manufacturer warranty coverage available — covering both materials and workmanship.
At least once a year — ideally in spring after the winter season. Middlesex County’s heavy snow, ice dams, and seasonal storms cause wear that isn’t visible from the ground. A professional inspection catches cracked flashing, lifted shingles, and moisture damage before they become expensive problems. D&G Exteriors offers free roof inspections across Middlesex County.
Yes — every roofing project starts with a free on-site inspection. We assess your roof’s condition, document everything with photos, and walk you through your options — repair vs. replacement, material choices, and warranty tiers. You’ll get a detailed written estimate with no pressure and no obligation.
Most full roof replacements take 1–3 days depending on roof size, pitch, and tear-off complexity. We handle all local permitting and full debris removal including a magnetic nail sweep of your property.
Missing or curling shingles, granule buildup in gutters, daylight through the attic, water stains on ceilings, and a roof older than 20 years. If the damage is isolated, repair usually makes sense. If issues are widespread or the roof is past its lifespan, replacement is more cost-effective. We’ll inspect for free and give you a straightforward recommendation.
We serve homeowners across Middlesex County including Burlington, Woburn, Lexington, Billerica, Bedford, Wilmington, Reading, Stoneham, Wakefield, and Winchester. Each town has different housing stock and exposure — we tailor our approach accordingly.
Manufacturer certifications — not just a license. A certification like CertainTeed Master Craftsman means the manufacturer has trained and vetted your installer and will back their work with a full warranty. Also check for verified Google reviews, Google Guaranteed status, and proper liability and workers’ comp insurance. D&G Exteriors holds all of the above.
Yes. We offer flexible financing options for both roof repairs and full replacements. Most Middlesex County homeowners qualify, and we’ll walk you through your options during your free estimate.
