Homeowners across Dorchester call Big Toms Roofing because we do what we say — show up on time, explain what we find in plain language, and stand behind every Flat Roof Repair job with a written warranty.
We built Big Toms Roofing to fix a problem every homeowner in Dorchester has run into: contractors who don't return calls, no-show for appointments, or pad the invoice once the tarp's already on the roof. Our Flat Roof Repair crews are local, licensed, and accountable — every estimate is in writing before a single shingle gets pulled.
From a single missing shingle to a full tear-off, our Dorchester crews handle every stage of roofing work with the same attention to detail — licensed, permitted, and cleaned up when we leave.
When a tree limb punches through decking or shingles peel back in a wind event, water gets in fast. We prioritize emergency calls in Dorchester above scheduled work, get a tarp on within hours, and document everything with photos for your insurance file.
A Flat Roof Repair replacement is one of the biggest investments a Dorchester homeowner makes in their property, and we treat it that way — daily site cleanup, magnetic nail sweeps, and a final walkthrough with the crew lead before we consider the job done.
Commercial roofs fail differently than residential ones — ponding water, seam separation, and membrane wear don't always show up until there's a leak on the sales floor below. Our Dorchester commercial division services TPO, EPDM, modified bitumen, and built-up roofing systems on retail, industrial, and multi-family properties.
A lot of roof failures are preventable with a twice-a-year inspection catching lifted flashing or worn pipe boots before they turn into interior water damage. Our Dorchester inspection service checks the field, flashing, penetrations, gutters, and attic ventilation, then hands you a written report with photos.
A roof is only as good as the parts that direct water off it. We repair and replace step flashing, valley flashing, chimney flashing, and gutters that have pulled away from the fascia — small jobs that prevent big leaks down the road.
Every one of these commitments exists because a Dorchester homeowner asked for it, complained about a competitor's lack of it, or we learned it the hard way.
You'll know the exact scope and cost in writing before work starts, and that number doesn't move unless you approve a change.
Local dispatch means less time waiting and more time getting your roof actually fixed.
Certification isn't a marketing badge here — it's required training that affects how your warranty is honored.
If something about the finished work doesn't sit right with you, call us back and we'll make it right — that's the deal.
We document damage the way adjusters expect to see it, which shortens the back-and-forth on storm claims.
Magnetic nail sweeps and tarp-protected landscaping are standard on every job, not an upsell.

"We had a leak show up during a storm at night and I honestly didn't expect anyone to answer the phone. Big Toms Roofing had a crew tarping our roof within a couple hours and came back two days later to do the real repair. Can't recommend them enough."
"I got three quotes for a full reroof and Big Toms Roofing wasn't the cheapest, but they were the only ones who explained exactly what was included and stuck to it. Zero surprises on the final bill."
"They handled the entire insurance claim conversation with our adjuster, sent over photo documentation, and honestly made a stressful situation way less stressful. Roof looks great too."
"As a property manager I've worked with a lot of roofing companies and Big Toms Roofing is one of the few that actually communicates before showing up and after the job's done."
"Bought a house in Dorchester last year and had them do the pre-purchase inspection. Found flashing issues the seller ended up covering. Saved us thousands before we even closed."
