Homeowners across Johnstown 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 Roof Installation job with a written warranty.

Big Toms Roofing has spent years building a reputation in Johnstown for doing Roof Installation the right way โ proper permits, manufacturer-approved materials, and a crew lead on-site for every job, not just a subcontractor nobody vetted.
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 Johnstown job.
High winds, hail, and fallen limbs don't schedule appointments, and neither should your repair. Our Johnstown 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.
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 โ ponding water, seam separation, and membrane wear don't always show up until there's a leak on the sales floor below. Our Johnstown 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 Johnstown 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.

Every one of these commitments exists because a Johnstown homeowner asked for it, complained about a competitor's lack of it, or we learned it the hard way.
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 Johnstown, we're rarely more than an hour from your address for emergency calls.
Certification isn't a marketing badge here โ it's required training that affects how your warranty is honored.
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.
We treat your yard and driveway like we'd want ours treated โ swept, protected, and cleared before we leave each day.
{We don't cherry-pick these โ they're representative of the calls, texts, and reviews we get after most Roof Installation jobs in Johnstown.}
"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."
"Their inspection before we bought our house flagged ventilation and flashing problems that weren't obvious on a walkthrough. Glad we called them before closing, not after."
