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 Thornton roofers to your door, usually the same day you call.
Big Toms Roofing has spent years building a reputation in Thornton for doing Roof Installation the right way — proper permits, manufacturer-approved materials, and a crew lead on-site for every job, not just a subcontractor nobody vetted.
From a single missing shingle to a full tear-off, our Thornton crews handle every stage of roofing work with the same attention to detail — licensed, permitted, and cleaned up when we leave.
A leak that starts as a small stain can rot decking and framing within weeks. Our emergency response teams treat every active-leak call in Thornton as urgent — temporary stabilization first, permanent fix scheduled right behind it.
A Roof Installation replacement is one of the biggest investments a Thornton homeowner makes in their property, and we treat it that way — daily site cleanup, magnetic nail sweeps, and a final walkthrough with the crew lead before we consider the job done.
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.
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 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, CO — we're trying to be the one you'd actually recommend to your neighbor.
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.
We treat your yard and driveway like we'd want ours treated — swept, protected, and cleared before we leave each day.
