Homeowners across Conowingo call Big Toms Roofing because we do what we say โ show up on time, explain what we find in plain language, and stand behind every Roofing job with a written warranty.

Big Toms Roofing has spent years building a reputation in Conowingo for doing Roofing the right way โ 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 Conowingo crews handle every stage of roofing work with the same attention to detail โ licensed, permitted, and cleaned up when we leave.
When a tree limb punches through decking or shingles peel back in a wind event, water gets in fast. We prioritize emergency calls in Conowingo above scheduled work, get a tarp on within hours, and document everything with photos for your insurance file.
A Roofing replacement is one of the biggest investments a Conowingo homeowner makes in their property, and we treat it that way โ 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 โ ponding water, seam separation, and membrane wear don't always show up until there's a leak on the sales floor below. Our Conowingo 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 Conowingo inspection service checks the field, flashing, penetrations, gutters, and attic ventilation, then hands you a written report with photos.
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 โ small jobs that prevent big leaks down the road.

We're not trying to be the biggest Roofing company in Conowingo, MD โ 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.
Because our trucks stay staged around Conowingo, 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.
If something about the finished work doesn't sit right with you, call us back and we'll make it right โ that's the deal.
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 โ they're representative of the calls, texts, and reviews we get after most Roofing jobs in Conowingo.}
"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."
"After the hail storm last year, Big Toms Roofing documented everything for our claim and dealt directly with our adjuster. We barely had to do anything except sign off on the estimate."
"We manage a small retail plaza and Big Toms Roofing has handled our flat roof maintenance for two years now. Scheduled work, no drama, invoices that match the estimate. Exactly what we need as a property manager."
"Bought a house in Conowingo 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."
