Homeowners across Duncannon 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 Duncannon and the surrounding Duncannon, PA 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 Duncannon 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 Duncannon as urgent — temporary stabilization first, permanent fix scheduled right behind it.
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 Duncannon 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.
Ice damming is a real problem in Duncannon, PA 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.

"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."
