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.
We built Big Toms Roofing to fix a problem every homeowner in Potomac 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.
Whether it's an emergency leak at 2am or a planned replacement you've been putting off, Big Toms Roofing brings the same certified crew and the same upfront pricing to every Potomac job.
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.
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.
We work directly with property management companies and HOAs across Potomac to keep flat and low-slope roofs maintained on a predictable schedule, instead of waiting for emergency calls that disrupt business.
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.
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.
We're not trying to be the biggest Flat Roof Repair company in Potomac, MD — we're trying to be the one you'd actually recommend to your neighbor.
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.
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 — 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 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."
"After the hail storm last year, Big Toms Roofing documented everything for our claim and dealt directly with our adjuster. We barely had to do anything except sign off on the estimate."
"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."
"Bought a house in Potomac 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."
