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.

Every Norwell roof replacement follows the same process — no shortcuts, no skipped steps. Here’s what’s included.

Most residential roof replacements in Norwell range from $12,000 to $35,000 depending on roof size, pitch, complexity, and any sheathing that needs replacing. Norwell’s larger homes with steep pitches, multiple dormers, and complex rooflines tend toward the higher end. We provide a detailed written estimate after inspecting the roof on site — no ballpark quotes over the phone.
Most residential roof replacements take 1–2 days of on-site work. Larger or more complex Norwell homes with steep pitches, multiple roof planes, or extensive sheathing replacement may take 2–3 days. We stage materials carefully on Norwell’s larger properties and coordinate access to minimize disruption to your property and landscaping.
We tear off to bare deck on every job — no exceptions. Going over existing shingles hides rot, traps moisture, and voids most manufacturer warranties. In Norwell, where homes sit under heavy tree canopy and deal with persistent moisture from shaded roofs, inspecting the deck is especially critical. We regularly find hidden sheathing damage that would have been buried under a layover.
We replace it. When the old shingles come off, we inspect every square foot of decking for rot, water damage, and soft spots. Any compromised sheathing gets cut out and replaced with new plywood before the underlayment and shingles go on. This is included in the project scope — we don’t charge surprise fees for reasonable amounts of sheathing replacement, and we communicate with you immediately if the scope changes significantly.
We assess the attic ventilation on every replacement and correct it if needed. Proper ridge vent, soffit intake, or both ensure the roof breathes correctly — poor ventilation is the number one cause of premature shingle failure and ice dams. Many older Norwell homes have inadequate original ventilation that we upgrade as part of the project. For Norwell’s tree-shaded roofs, ventilation is especially important.
We install CertainTeed Landmark and Landmark Pro architectural shingles — CertainTeed’s most popular residential lines. As a CertainTeed Master Craftsman contractor, we’re factory-trained to install to manufacturer spec, which qualifies every Norwell project for the strongest warranties available. We bring color samples to the consultation so you can choose in natural light against your home’s existing exterior.
Yes. The Town of Norwell requires a building permit for roof replacement. We handle the permit application, schedule all required inspections, and make sure everything meets code. You don’t need to coordinate with Town Hall — that’s all included in the project.
We’re CertainTeed Master Craftsman certified — their highest contractor level — Google Guaranteed, BBB Accredited with an A+ rating, and NRCA Affiliated. Master Craftsman requires advanced training and demonstrated installation quality. Every Norwell replacement gets the same crew, project manager, and quality standards regardless of the home’s size.
