Homeowners across Gambrills 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 Roof Installation job with a written warranty.

We built Big Toms Roofing to fix a problem every homeowner in Gambrills 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 Roof Installation 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 Gambrills 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 Gambrills above scheduled work, get a tarp on within hours, and document everything with photos for your insurance file.
A Roof Installation replacement is one of the biggest investments a Gambrills homeowner makes in their property, and we treat it that way โ daily site cleanup, magnetic nail sweeps, and a final walkthrough with the crew lead before we consider the job done.
We work directly with property management companies and HOAs across Gambrills to keep flat and low-slope roofs maintained on a predictable schedule, instead of waiting for emergency calls that disrupt business.
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 Gambrills inspection service checks the field, flashing, penetrations, gutters, and attic ventilation, then hands you a written report with photos.
Poor attic ventilation cooks shingles from underneath and can void manufacturer warranties. Our Gambrills crews balance intake and exhaust ventilation to extend the life of your Roof Installation system and lower attic temperatures in summer.

Every one of these commitments exists because a Gambrills 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.
Because our trucks stay staged around Gambrills, we're rarely more than an hour from your address for emergency calls.
Certification isn't a marketing badge here โ it's required training that affects how your warranty is honored.
Every completed job comes with a written workmanship warranty separate from the manufacturer's material warranty.
We document damage the way adjusters expect to see it, which shortens the back-and-forth on storm claims.
We treat your yard and driveway like we'd want ours treated โ swept, protected, and cleared before we leave each day.
