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 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.

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.
