Homeowners across Potomac 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.
Big Toms Roofing isn't a national call center that dispatches whoever's cheapest that week. We're a licensed roofing operation built around Potomac and the surrounding Potomac, MD communities, with crews who know the local building codes, the weather patterns, and the housing stock inside and out.
From a single missing shingle to a full tear-off, our Potomac crews handle every stage of roofing work with the same attention to detail — licensed, permitted, and cleaned up when we leave.
A leak that starts as a small stain can rot decking and framing within weeks. Our emergency response teams treat every active-leak call in Potomac as urgent — temporary stabilization first, permanent fix scheduled right behind it.
A Flat Roof Repair replacement is one of the biggest investments a Potomac 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 Potomac 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 Potomac 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 Potomac 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 Potomac 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 Potomac, 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.
Every completed job comes with a written workmanship warranty separate from the manufacturer's material warranty.
Our team has sat through enough adjuster meetings in Potomac, MD to know what documentation actually moves a claim forward.
We treat your yard and driveway like we'd want ours treated — swept, protected, and cleared before we leave each day.
{We don't cherry-pick these — they're representative of the calls, texts, and reviews we get after most Flat Roof Repair jobs in Potomac.}
"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."
"The estimate they gave us matched the final invoice exactly, which after two other quotes from companies that kept adding line items, was a relief. Crew was professional and cleaned up better than I expected."
"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."
"We manage a small retail plaza and Big Toms Roofing has handled our flat roof maintenance for two years now. Scheduled work, no drama, invoices that match the estimate. Exactly what we need as a property manager."
"Their inspection before we bought our house flagged ventilation and flashing problems that weren't obvious on a walkthrough. Glad we called them before closing, not after."
