A damaged roof doesn't wait for a convenient time, and neither do we. Big Toms Roofing keeps trucks staged around Thornton 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 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, CO 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.
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 Replacement 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.
Downtime costs money, so commercial Roof Replacement jobs get scheduled around your operating hours whenever possible, with clear communication to property managers and tenants throughout the project.
Buying or selling a home in Thornton? A pre-purchase roof inspection gives you real leverage in negotiations and peace of mind about what you're actually buying — no guessing about remaining roof life.
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 Replacement company in Thornton, CO — 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 Thornton, 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.
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 Thornton.}
"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."
"The estimate they gave us matched the final invoice exactly, which after two other quotes from companies that kept adding line items, was a relief. Crew was professional and cleaned up better than I expected."
"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."
"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."
"Bought a house in Thornton last year and had them do the pre-purchase inspection. Found flashing issues the seller ended up covering. Saved us thousands before we even closed."
