Homeowners across Winthrop call Big Toms Roofing because we do what we say โ 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 Winthrop 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 โ every estimate is in writing before a single shingle gets pulled.
From a single missing shingle to a full tear-off, our Winthrop crews handle every stage of roofing work with the same attention to detail โ 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 Winthrop above scheduled work, get a tarp on within hours, and document everything with photos for your insurance file.
When patching stops making financial sense, a full tear-off and reroof resets the clock on your home. We strip old material down to the deck, replace any rotten sheathing, install proper underlayment and ice-and-water protection, and finish with a manufacturer-certified shingle or metal system backed by a real warranty.
Downtime costs money, so commercial Flat Roof Repair jobs get scheduled around your operating hours whenever possible, with clear communication to property managers and tenants throughout the project.
After a wind or hail event, insurance companies want documented proof of damage. Our inspection team photographs and reports storm damage in a format adjusters recognize, which speeds up claim approval.
Poor attic ventilation cooks shingles from underneath and can void manufacturer warranties. Our Winthrop crews balance intake and exhaust ventilation to extend the life of your Flat Roof Repair system and lower attic temperatures in summer.

Every one of these commitments exists because a Winthrop homeowner asked for it, complained about a competitor's lack of it, or we learned it the hard way.
Every estimate is itemized and handed to you before we touch the roof โ no verbal quotes that change once the ladder comes down.
Because our trucks stay staged around Winthrop, we're rarely more than an hour from your address for emergency calls.
Our installers hold current manufacturer certifications, which means your warranty stays intact and the work meets code.
If something about the finished work doesn't sit right with you, call us back and we'll make it right โ that's the deal.
