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.

Hamilton’s large rural lots, horse properties, and mix of antique colonials and estate homes create roofing challenges — mature tree canopy, complex rooflines, and aging sheathing beneath decades-old shingles.

It depends on what’s needed. Targeted repairs — flashing, a few shingles, ice dam fixes — typically run $800–$3,000. Full roof replacements range from $12,000 to $35,000 depending on roof size, pitch complexity, and deck condition. Hamilton’s larger estate homes with steep pitches and multiple dormers are on the higher end. We provide a detailed written estimate after an on-site inspection.
We inspect the roof and give you an honest assessment. If it’s under 15 years old with isolated damage — a failed flashing, storm damage, a few lifted shingles — a targeted repair usually makes sense. If the damage is widespread, shingles are curling across the roof, or we find significant sheathing rot during inspection, replacement is the better investment. We never push replacement when repair will do.
Failed flashing around chimneys, walls, and valleys is the most common cause. Ice dams are a close second — Hamilton’s tree canopy shades roofs and holds snow, and many older homes have ventilation issues that make ice dams worse. Moss and algae growth from shaded roof sections also traps moisture and accelerates shingle deterioration over time. Pipe boots and vent penetrations are another frequent leak source.
Hamilton’s mature tree canopy shades roofs, traps moisture, and creates conditions for moss and algae growth that accelerate shingle deterioration. Fallen branches damage shingles and flashing. Leaf debris clogs valleys and gutters, causing water backup and ice dams. We assess shade patterns during every inspection and recommend trimming branches 6–8 feet above the roofline.
Yes. Many Hamilton homes have low-slope sections — additions, porches, sunrooms, or barn-style outbuilding roofs. We install EPDM and TPO membranes with proper drainage, sealed seams, and clean transitions to pitched roof sections. Flat-to-pitched transitions are where most failures occur, and we detail them properly.
Poor ventilation traps heat and moisture in the attic, accelerating shingle failure from the underside and promoting ice dams in winter. Many older Hamilton homes weren’t built with adequate ventilation — tight attic spaces, insufficient soffit intake, or no ridge vent. We assess ventilation on every inspection and upgrade ridge vents, soffit vents, and baffles where needed. Proper ventilation is especially critical on shaded, tree-covered Hamilton roofs.
Yes. The Town of Hamilton requires a building permit for roof replacement. Most minor repairs don’t require permits. We handle all permit applications, schedule required inspections, and make sure everything meets current building code. You don’t need to coordinate with Town Hall — that’s included in the project.
