Flat and low-slope roofs have different failure points than pitched roofs. Ponding water, membrane seam failures, punctures, and flashing issues around penetrations are the most common problems — and they're not always obvious until water is already getting through.
RJ Roofing & Contracting repairs TPO and EPDM flat roofing systems on residential and commercial properties across Joplin, MO and Southwest Missouri. We inspect the full membrane, identify where the system is failing, and repair it correctly so the problem doesn't come back in the same spot.
Flat roof repairs that are done right — seams properly welded or bonded, flashing fully sealed, membrane integrity restored — hold up. Flat roof repairs that just address the surface symptom without finding the actual failure point don't. We take the time to find the source before we start the repair.

📞 Call 417-499-6697We repair TPO and EPDM flat roofing systems on residential and commercial properties. Here's what each system involves and how we approach repairs.
Thermoplastic polyolefin (TPO) is one of the most common flat roofing systems on commercial buildings in Joplin. TPO seams are heat-welded, which makes them strong when properly installed — but seam failures, punctures, and flashing issues do occur over time.
We repair TPO membrane tears, re-weld failing seams, address flashing failures around penetrations and curbs, and patch punctures. If the system is nearing the end of its life, we'll tell you that too rather than keep patching a failing membrane.
EPDM rubber roofing is a proven flat roofing system that handles Southwest Missouri's temperature swings well. Over time, EPDM seams can separate, the membrane can shrink and pull away from edges and flashings, and punctures can develop from foot traffic or debris.
We repair EPDM membrane separations, reseal lifted edges and flashings, patch punctures, and address drain and penetration failures. EPDM repairs done correctly with the right adhesives and materials hold up — we don't cut corners on material compatibility.
Flat roofs fail in predictable ways. Here's what we see most often and how we address it.
Seams are the most common failure point on both TPO and EPDM systems. On TPO, heat-welded seams can separate over time. On EPDM, adhesive seams can lift and peel. A failing seam is an open water entry point — we locate and repair every seam failure we find, not just the obvious ones.
Flat roofs are designed to drain — water that pools and sits for more than 48 hours is a sign of a drainage problem. Standing water accelerates membrane deterioration and adds structural load. We assess the drainage situation and address what's causing the ponding.
Where the membrane meets walls, curbs, skylights, and penetrations is where most flat roof leaks originate. Flashing that has lifted, cracked, or separated is a direct path for water into the building. We repair and reseal all flashing as part of any flat roof repair.
HVAC equipment, foot traffic, and falling debris can puncture flat roofing membranes. A small puncture that goes unaddressed lets water in every time it rains. We locate and patch punctures with compatible materials that bond properly to the existing membrane.
Blisters on a flat roof membrane are pockets of air or moisture trapped between layers. They indicate adhesion failure and will eventually crack and allow water in. We assess the extent of blistering and determine whether spot repair or broader membrane work is needed.
The areas around roof drains, pipes, and mechanical penetrations are high-risk leak points. Seals deteriorate over time and the membrane can pull away from these areas. We inspect and reseal all penetrations as part of any flat roof assessment.
Flat roofing systems require a different approach than pitched roofs — the materials are different, the failure points are different, and the repair methods are specific to the system type. A TPO repair done with EPDM materials won't hold. Getting the right person for the right system matters.

We repair TPO and EPDM flat roofing systems. If you're not sure what system you have, we can identify it during a free inspection. Call 417-499-6697.
Common signs include water pooling that doesn't drain within 48 hours, bubbling or blistering on the membrane surface, visible seam separations, water stains on interior ceilings, or soft spots when walking the roof. If you're seeing any of these, call 417-499-6697 for a free inspection.
It depends on the age of the membrane, how widespread the damage is, and whether the underlying insulation and decking have been compromised. Localized damage on a system that still has useful life is generally repairable. A membrane that is cracking, shrinking, and failing across large areas is a replacement conversation. We'll give you an honest answer after we inspect it.
