A damaged roof doesn't wait for a convenient time, and neither do we. Big Toms Roofing keeps trucks staged around Markham so a certified roofer can be looking at your roof within hours, not days, with a straight-talk estimate before any work starts.
Big Toms Roofing has spent years building a reputation in Markham for doing 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.
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 Markham job.
When a tree limb punches through decking or shingles peel back in a wind event, water gets in fast. We prioritize emergency calls in Markham above scheduled work, get a tarp on within hours, and document everything with photos for your insurance file.
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.
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.
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 Roof Repair 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.
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.
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.
We document damage the way adjusters expect to see it, which shortens the back-and-forth on storm claims.
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 Roof Repair jobs in Markham.
"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."
"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."
