D&G Roofing & Siding, based in Burlington, is the contractor several reviewers say they wish they'd called first — a recurring theme is homeowners who'd already been burned by another company's shortcuts before D&G fixed the underlying problem. John (with Shane leading some crews) runs jobs across a wide stretch of towns north and west of Boston — Winchester, Lexington, Bedford, Wilmington, Lynnfield, Stoneham, and more — covering roofing, siding, windows, gutters, and decks. The diagnostic work stands out. One homeowner had a recurring leak that two other companies wanted to solve by selling a full roof replacement; John instead traced the water path in the attic and found a failed pipe boot and a section of pulled step flashing. Another had a water problem two prior contractors misdiagnosed as either a roof or gutter issue — D&G found the real cause was failed flashing where the roof met a dormer wall. A third hired D&G to correct a botched roof job from another company, where improperly installed underlayment and inadequate ventilation had shingles lifting within two years. On bigger jobs, the pattern holds: a homeowner debating an uncommon standing-seam metal roof said John was the only contractor willing to talk through the tradeoffs honestly instead of steering them back to shingles. Multi-trade projects — a full roof-and-siding overhaul, a combined siding-and-window job timed together to save money, structural repairs uncovered mid-demolition — come up again and again, often broken into phases so homeowners aren't writing one enormous check. One family rebuilt a wobbly, unsafe deck into a space their kids "basically live" on now; another swapped out drafty original windows and watched their heating bill drop the first month. The reviews lean heavily positive and specific, and Google shows 5 stars across 130 ratings; there's no licensing or BBB record in view here to check independently, so it's worth confirming registration status directly before signing. For a roof, siding, or deck project anywhere from Burlington out to Lincoln or Wilmington, the pattern in the reviews is a company that digs for the actual cause of a problem rather than upselling a bigger job — worth asking for the same kind of walkthrough other customers describe getting.

A square is 100 sq ft of roof surface — bigger than the floor plan because of pitch and overhangs.

We went back and forth for months on whether to do a standing seam metal roof on our colonial. It's a less common choice around here and a few people told us we were crazy. John was one of the only contractors who didn't try to talk us out of it. He walked us through the pros and cons honestly, explained how the installation differs from shingles, and helped us pick a color that works with the style of the house. The finished roof is stunning. It has this clean, crisp look that shingles just can't match, and knowing it's going to outlast us in this house makes the higher upfront cost feel like a smart decision. We've had people slow down driving past to look at it, which is kind of funny. Zero regrets.
New roof on our Woburn garrison. Looks sharp, went fast, no issues. Solid company.
Had a roof leak that showed up every time we got a heavy northeast rain. Called three companies. Two wanted to sell us a full replacement. John came out, spent time in the attic tracing the water path, and found a failed pipe boot and a section of step flashing that had pulled away from the wall. His crew fixed both and the leak is gone. That was seven months ago. Really appreciate that he diagnosed the actual problem instead of jumping to the most expensive option.
We selected D&G for a rather involved project on our Lexington home. Full roof replacement with an upgraded architectural shingle, new fiber cement siding, and custom aluminum trim work throughout. Our home is a 1960s contemporary with a lot of angles and large overhangs, so the execution had to be precise or it would have looked terrible. John clearly understood what we were going for. His crew handled the transitions between materials and roof planes with care, and the finished result is exactly what we envisioned. The house has a completely different character now. Clean, modern, well proportioned. Several neighbors have commented on how much the property has changed. We are very pleased with the outcome.
"We moved to Burlington two years ago and the house needed exterior work badly. Roof was at the end of its life, the siding had seen better days, and the whole place just looked tired. We asked John to come take a look and he put together a scope that covered everything, roof, siding, trim wrap, and gutters. It was a big investment for us but the house honestly needed all of it. The project ran about three and a half weeks total. There were a couple of weather delays but the crew communicated well about scheduling and never left things half done when they had to stop for the day. The transformation is pretty remarkable. We went from having one of the most run down houses on the street to one that people actually compliment. My mother in law said it looks like a different house entirely, and she's not easy to impress. Very happy we went with D&G Roofing & Siding."
