Medford’s housing stock is roughly half pre-war — colonials and Victorians in West Medford, triple-deckers along Boston Avenue, bungalows and two-families throughout Hillside and South Medford. Each building type has different roofing challenges, and most of them have been reroofed at least twice already.

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. John took the time to explain things without talking down to us, which we really appreciated.

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.

Repairs typically run $850–$3,000. Full replacements range from $12,000 to $30,000 depending on roof size, pitch, and deck condition. Medford’s triple-deckers and multi-family buildings can run higher due to multiple roof sections and flat-to-pitched transitions.
Yes, and Medford has a lot of them. We handle tenant coordination, phased scheduling when needed, and the flat-to-pitched transitions that are common on multi-family buildings. Same crew, same standards as single-family work. We also work with Medford businesses and commercial properties.
Heat escaping through poorly ventilated attics melts roof snow unevenly. The meltwater refreezes at colder eaves, forming a dam that backs water under shingles. Medford’s older homes are prone because of inadequate attic insulation and ventilation — especially triple-deckers where heat from lower units rises through the building.
Age and construction. Pre-war homes have board sheathing, hand-framed rafters, and rooflines that have been patched and reroofed multiple times. Chimneys have been reflashed repeatedly, valleys are hand-cut at odd angles, and dormers create vulnerable points that need more precision.
Yes. EPDM and TPO membrane systems with proper seam welding, tapered insulation for drainage, and clean transitions where flat meets pitched. Medford’s multi-family buildings and commercial properties (Medford based businesses) often have flat sections that need membrane roofing — it’s a significant part of our work in this city.
Most single-family roof replacements take 1–2 days. Triple-deckers and larger multi-family buildings may take 2–4 days depending on roof sections and deck condition. You’ll have a clear timeline before we start.
Yes. The City of Medford requires building permits for roof replacement. We handle the application, schedule inspections, and ensure the work meets current code.
