Flat Roof Repair & Coatings in O’Fallon, MO

Flat roofs are common on commercial buildings in O’Fallon, but more and more homeowners are adding them to garages, sunrooms, and home additions. The challenge? Flat roofs don’t shed water like pitched roofs. If they aren’t maintained properly, leaks, pooling water, and cracking membranes can become major problems.

One of our recent commercial clients in the Progress West area was dealing with a persistent leak above their breakroom. Their old rolled roofing was cracked and holding water. We recommended a TPO patch and followed it with a white elastomeric coating that not only sealed the surface but reflected the sun’s heat and reduced energy costs. Since then, their leak is gone and their cooling bills dropped by nearly 20%.

At O’Fallon Roofing Pros, we specialize in flat roof repair and protective coatings designed to extend the life of your roof and stop water infiltration before it causes costly interior damage.

Our Flat Roof Services

Flat Roof Leak Detection & Patching
We use thermal imaging and visual inspection to pinpoint flat roof leaks. Whether it’s ponding, membrane punctures, or flashing failures, we patch the problem fast to protect your building.

TPO, EPDM, & Modified Bitumen Repairs
We service all major flat roofing systems, including thermoplastics, rubber roofs, and asphalt-based materials. We repair seams, punctures, shrinkage, and weather-related damage.

Elastomeric & Acrylic Roof Coatings
Coatings are a cost-effective way to reseal aging flat roofs without full replacement. We install energy-efficient white coatings that reflect UV rays, reduce heat gain, and resist cracking.

Drainage Correction & Gutter Upgrades
Flat roofs need effective drainage. We inspect and upgrade scuppers, internal drains, and downspouts to ensure water doesn’t pool and degrade the membrane.

Flashing & Curb Reinforcement
HVAC curbs, vents, and skylights are common leak points on flat roofs. We reinforce these areas with new flashing and sealants designed to flex and hold up over time.

Roof Coating Overlays vs. Tear-Offs
Not sure if your flat roof can be coated or if it needs replacement? We’ll assess the current membrane condition and give you a clear recommendation—no pressure, just facts.
