Homeowners across Markham 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 Roof Replacement job with a written warranty.
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 Replacement 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.
We work directly with property management companies and HOAs across Markham to keep flat and low-slope roofs maintained on a predictable schedule, instead of waiting for emergency calls that disrupt business.
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.
You'll know the exact scope and cost in writing before work starts, and that number doesn't move unless you approve a change.
Because our trucks stay staged around Markham, we're rarely more than an hour from your address for emergency calls.
Certification isn't a marketing badge here — it's required training that affects how your warranty is honored.
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 Replacement jobs in Markham.

"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."
