Seam separation, punctures, or membrane shrinkage on your flat or low-slope roof? Simmons Roofing repairs EPDM rubber roofs across Southeast Missouri — sealed watertight.
EPDM is a durable synthetic rubber membrane, but like any flat-roof system it needs attention over time. Seams can separate, the membrane can be punctured, and it can shrink and pull at the edges and flashing — and on a flat roof, any of those is a direct path for water. Simmons Roofing repairs EPDM roofs across Southeast Missouri and reseals them watertight.
Every repair starts with a thorough inspection to find the true source. On EPDM, leaks most often develop at the seams, flashing, penetrations, or a puncture — and because water sits on a flat roof, even a small gap matters.
As a family-owned company that's licensed, insured, and bonded, we stand behind our repairs, and every one begins with a free, no-obligation estimate.
These are the issues we most often repair on EPDM rubber roofs.
Open or lifting seams cleaned and resealed for a continuous, watertight bond.
Holes and tears in the membrane patched and sealed.
Shrinkage that pulls at edges and flashing corrected and resealed.
Flashing and drainage details repaired where water tends to collect.
A flat roof doesn't shed water the way a sloped roof does — it holds it and drains slowly, so the membrane has to be genuinely watertight. That's what makes even a small seam gap or puncture such a problem: there's nowhere for the water to go but in.
The good news is that EPDM is one of the easier roofing systems to repair when you catch the issue early. A clean, properly sealed seam or patch restores the membrane's integrity and can add years to the roof's life.
Whether it's a home addition, porch, or commercial building, we'll find the leak and seal it right.

EPDM leaks most often develop at the seams where sheets join, at flashing and roof penetrations, or from a puncture in the membrane. Over time the membrane can also shrink and pull at the edges. We inspect all of these areas to find where water is actually getting in.
Yes — that's one of EPDM's biggest advantages. Punctures, tears, and open seams can usually be cleaned, patched, and resealed to restore a watertight membrane, without replacing the whole roof.
A properly done EPDM repair — with the surface cleaned and prepared correctly and quality materials used — can last for years. The key is repairing it right, which is exactly the standard we work to.
Yes. EPDM is very common on commercial buildings, and we repair commercial and residential EPDM roofs alike, at every scale.
It depends on the roof's age and the extent of the problem. Isolated seams, punctures, or flashing issues are usually a straightforward repair. If the membrane is near the end of its life or failing in many places, we'll walk you through your options honestly.
