Homeowners across Longmont 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 Flat Roof Repair job with a written warranty.

Big Toms Roofing has spent years building a reputation in Longmont for doing Flat Roof Repair 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 Longmont crews handle every stage of roofing work with the same attention to detail โ licensed, permitted, and cleaned up when we leave.
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 Longmont as urgent โ temporary stabilization first, permanent fix scheduled right behind it.
When patching stops making financial sense, a full tear-off and reroof resets the clock on your home. We strip old material down to the deck, replace any rotten sheathing, install proper underlayment and ice-and-water protection, and finish with a manufacturer-certified shingle or metal system backed by a real warranty.
We work directly with property management companies and HOAs across Longmont to keep flat and low-slope roofs maintained on a predictable schedule, instead of waiting for emergency calls that disrupt business.
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 Longmont inspection service checks the field, flashing, penetrations, gutters, and attic ventilation, then hands you a written report with photos.
Ice damming is a real problem in Longmont, CO 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."
