Homeowners across Thornton 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 Installation job with a written warranty.
Big Toms Roofing isn't a national call center that dispatches whoever's cheapest that week. We're a licensed roofing operation built around Thornton and the surrounding Thornton, IL communities, with crews who know the local building codes, the weather patterns, and the housing stock inside and out.
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 Thornton 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 Thornton 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 Thornton 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 Thornton inspection service checks the field, flashing, penetrations, gutters, and attic ventilation, then hands you a written report with photos.
Poor attic ventilation cooks shingles from underneath and can void manufacturer warranties. Our Thornton crews balance intake and exhaust ventilation to extend the life of your Roof Installation system and lower attic temperatures in summer.
We're not trying to be the biggest Roof Installation company in Thornton, 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.
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.
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 Thornton.

"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."
