When a shingle blows off in a storm or a slow leak finally shows up on your ceiling, you need a crew that answers the phone and shows up — not a call center that puts you on hold. Big Toms Roofing sends licensed, local Derwood roofers to your door, usually the same day you call.
We built Big Toms Roofing to fix a problem every homeowner in Derwood 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 Derwood 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 Derwood above scheduled work, get a tarp on within hours, and document everything with photos for your insurance file.
Whether your roof is past its expected lifespan or storm damage made repair impractical, our replacement crews handle permitting, disposal, and installation start to finish, with a written timeline you can plan around.
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 Derwood 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 Derwood 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 Derwood 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 Derwood 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 Derwood, we're rarely more than an hour from your address for emergency calls.
Certification isn't a marketing badge here — 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.
Magnetic nail sweeps and tarp-protected landscaping are standard on every job, not an upsell.
{We don't cherry-pick these — they're representative of the calls, texts, and reviews we get after most Flat Roof Repair jobs in Derwood.}
"Called around 9pm after a branch came through part of our roof and Big Toms Roofing actually picked up. They had someone out that night to stop the water and scheduled the repair for that week. That kind of response is rare."
"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."
"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."
"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."
Big Toms Roofing crews are staged to cover all of Derwood and the neighborhoods around it, from established residential streets to newer developments and commercial corridors.
