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 Markham roofers to your door, usually the same day you call.
Big Toms Roofing has spent years building a reputation in Markham for doing Flat Roof Repair the right way — proper permits, manufacturer-approved materials, and a crew lead on-site for every job, not just a subcontractor nobody vetted.
From a single missing shingle to a full tear-off, our Markham 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 Markham 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.
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 Markham 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 Markham inspection service checks the field, flashing, penetrations, gutters, and attic ventilation, then hands you a written report with photos.
Ice damming is a real problem in Markham, IL winters when it happens. We install proper ice-and-water shield and improve attic insulation and ventilation to stop the freeze-thaw cycle that damages eaves.
Every one of these commitments exists because a Markham 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 — no verbal quotes that change once the ladder comes down.
Local dispatch means less time waiting and more time getting your roof actually fixed.
Certification isn't a marketing badge here — it's required training that affects how your warranty is honored.
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 Markham.
"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."
"I got three quotes for a full reroof and Big Toms Roofing wasn't the cheapest, but they were the only ones who explained exactly what was included and stuck to it. Zero surprises on the final bill."
"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."
"Bought a house in Markham 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."
Big Toms Roofing crews are staged to cover all of Markham and the neighborhoods around it, from established residential streets to newer developments and commercial corridors.
