Posted on Bradford JonesTrustindex verifies that the original source of the review is Google. We had been in our home a long time and exterior was due for serious updates. Roof was from the early 90s, siding was peeling in layers, and the windows were old vinyl with seal failure and had no insulation. We kept putting it off until a neighbor recommended John. He spent over an hour walking the property with us on the first visit, pointing out things we hadn't even noticed, including a section where moisture had been getting behind the siding for years. He didn’t pressure us, just a clear explanation of what was going on and what it would take to fix it right. We ended up doing everything. Full roof, new siding, all new windows, and complete trim. The crew showed up early, kept the property clean (and cleaned up after), and communicated well throughout. When they found more damage than expected behind one wall, John called same day with pictures and options before moving forward. The transparency was both refreshing and important. It's been about a year and a half and everything still looks and performs exactly as it should. Heating costs dropped noticeably and was especially apparent this year. We live on a main street and the noise in our front bedrooms is gone. The house legitimately looks like a completely different property. If you're in the north shore area thinking about exterior work, get a quote and talk to John. You'll see the difference.Posted on Roman CooperTrustindex verifies that the original source of the review is Google. We have a big old farmhouse out in Boxford with a roof that probably should've been replaced five years ago. Finally pulled the trigger and called D&G Exteriors. John came out, looked everything over, and gave us a quote that was fair and detailed. Crew did the whole tear off and install in three days. No complaints at all.Posted on Parker SimmonsTrustindex verifies that the original source of the review is Google. I’m so impressed with the service I received.

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.
