EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane that has been a staple of commercial and residential flat roofing for decades. Black or white, it is valued for its durability, flexibility across temperature extremes, and resistance to UV and ozone. EPDM roofing is common throughout Austin's commercial building stock and on residential flat and low-slope sections.

EPDM is one of the most durable flat roofing membranes available — and with the right maintenance, it can last decades in Austin.
EPDM rubber is inherently resistant to UV and ozone degradation — a meaningful advantage in Austin's climate. However, the adhesives and lap seams used to join sheets and the tape used at seams can fail over time, particularly in high-heat environments where adhesive bonds experience repeated thermal cycling. A membrane that looks intact may have seam separations beneath its surface that allow water infiltration. Regular inspection and maintenance of seams, penetrations, and perimeter terminations keeps EPDM systems performing well past their expected lifespan.
We inspect the entire membrane surface, all lap seams, perimeter flashing terminations, and penetrations for any signs of seam separation, membrane damage, or failed adhesive.
EPDM repairs use EPDM-compatible patch membrane and bonding adhesive or seam tape — not caulk or generic sealants that will fail under thermal cycling.
Failed seams are cleaned, re-primed, and re-adhered or re-taped. Perimeter terminations and penetration flashings are inspected and repaired or replaced as needed.
EPDM requires specific materials and technique for lasting repairs. We use the right products and apply them correctly so repairs hold up through Austin's heat and UV exposure.
We repair EPDM with compatible materials and correct technique — repairs that hold up rather than requiring re-repair in a year.

Well-maintained EPDM roofing typically lasts 20-30 years. The membrane itself ages well in UV, but seam adhesives and lap tape used in older installations can degrade. Regular seam inspection and maintenance significantly extends service life.
Lap seam failures are frequently invisible from above. The membrane sheets overlap and appear fine visually, but the adhesive bond between them has failed underneath, allowing water entry. Systematic seam probing is the only reliable way to identify these failures.
Yes. Liquid-applied EPDM-compatible coatings can rejuvenate aging EPDM membranes and extend service life, provided the existing membrane is still structurally sound. This is often more cost-effective than full replacement when the membrane has no widespread damage.
