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.
We built Big Toms Roofing to fix a problem every homeowner in Duncannon 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 Installation 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 Duncannon 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 Duncannon 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.
A Roof Installation replacement is one of the biggest investments a Duncannon 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 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.
Poor attic ventilation cooks shingles from underneath and can void manufacturer warranties. Our Duncannon crews balance intake and exhaust ventilation to extend the life of your Roof Installation system and lower attic temperatures in summer.
Every one of these commitments exists because a Duncannon homeowner asked for it, complained about a competitor's lack of it, or we learned it the hard way.
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 Duncannon, 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.
