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.
We built Big Toms Roofing to fix a problem every homeowner in Markham 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 Gutter Installation 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 Markham crews handle every stage of roofing work with the same attention to detail — licensed, permitted, and cleaned up when we leave.
High winds, hail, and fallen limbs don't schedule appointments, and neither should your repair. Our Markham emergency crews arrive with tarps, decking material, and fasteners to stop active leaks the same day you call, then follow up with a full repair plan once the storm passes.
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.
Buying or selling a home in Markham? A pre-purchase roof inspection gives you real leverage in negotiations and peace of mind about what you're actually buying — no guessing about remaining roof life.
Poor attic ventilation cooks shingles from underneath and can void manufacturer warranties. Our Markham crews balance intake and exhaust ventilation to extend the life of your Gutter Installation system and lower attic temperatures in summer.
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.
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 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."
"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."
"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 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."
