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.
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 Roof 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.
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 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.
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 Roof Installation company in Markham, IL — we're trying to be the one you'd actually recommend to your neighbor.
Every estimate is itemized and handed to you before we touch the roof — no verbal quotes that change once the ladder comes down.
Because our trucks stay staged around Markham, we're rarely more than an hour from your address for emergency calls.
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.
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 Roof Installation 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."
"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."
