Lexington is one of the most affluent and well-maintained towns in Greater Boston — historic homes near the center, established neighborhoods with mature tree canopy, and newer custom builds on generous lots. Homeowners here invest in their properties and expect the contractors who work on them to match that standard. The roofing company you hire needs to treat the project — and the property — accordingly.

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.
Lexington’s housing stock spans three centuries — from pre-Revolutionary antiques near the center to mid-century ranches, 1970s–80s colonials, and newer custom construction. Each era brought different roofing systems, pitches, and ventilation requirements. Here’s what we handle.

Most residential roof replacements in Lexington range from $12,000 to $35,000 depending on roof size, pitch, complexity, and any sheathing that needs replacing. Lexington’s larger homes with steep pitches, multiple dormers, and complex rooflines tend to be on the higher end. We provide a detailed written estimate after inspecting the roof on site.
If your roof is under 15 years old and the issue is isolated — a flashing failure, a few missing shingles, or localized ice dam damage — repair usually makes sense. If the shingles are 20+ years old, showing widespread granule loss or curling, or you’ve had multiple repairs in recent years, replacement is the better investment. We inspect and give you an honest recommendation.

Yes, absolutely. Lexington is inland with heavy tree canopy that shades roofs and holds snow longer. Homes with inadequate attic ventilation or insulation are especially prone. We assess and correct ventilation on every replacement, and install full ice & water shield at eaves, valleys, and penetrations. On repair projects, we address the underlying ventilation issue along with the visible damage.
Yes. Lexington has a significant stock of antique and historic homes, some dating to the 18th century. We understand the care required — steep pitches, original framing details, tight access, and preservation considerations. We treat every historic property with the respect it deserves while ensuring the roofing system meets modern performance standards.
Yes. We pull the building permit through the Town of Lexington, 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.
