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.

It depends on what’s needed. Targeted repairs — flashing, a few shingles, ice dam fixes — typically run $500–$3,000. Full roof replacements range from $10,000 to $30,000 depending on roof size, pitch complexity, and deck condition. Andover has everything from compact capes to large colonials and historic homes, so the range is wide. 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. Andover homes from the 1950s through 1980s are often approaching or past the expected lifespan of their original roof — we’ll let you know what we find.
Failed flashing around chimneys, walls, and valleys is the most common cause. Ice dams are a close second — many Andover colonials have complex rooflines with inadequate attic ventilation, which traps heat and creates ice dams along the eaves every winter. Pipe boots and vent penetrations dry out and crack over time and are another frequent leak source.
Many of Andover’s colonials have steep pitches with complex rooflines and limited attic ventilation. Heat escapes into the attic, melts snow on the upper roof, and the meltwater refreezes at the colder eaves — forming ice dams that back water under shingles. We address ventilation on every project and install ice & water shield at all vulnerable points to prevent damage even when ice dams do form.
Yes. Many Andover homes have low-slope sections — additions, sunrooms, or garage 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. We also handle metal roofing in Andover.
Poor ventilation traps heat and moisture in the attic, accelerating shingle failure from the underside and promoting ice dams in winter. Many Andover homes — especially older colonials and homes with finished attic spaces — weren’t built with adequate ventilation by today’s standards. We assess ventilation on every inspection and upgrade ridge vents, soffit vents, and baffles where needed.
Yes. The Town of Andover 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.
