    EPDM Rubber Roofing50+ Years of Proven Performance

    EPDM rubber roofing has been protecting commercial buildings for over half a century. Installations from the 1980s are still going strong today — a testament to this material's remarkable durability.

    Why EPDM Works for Oklahoma Commercial Buildings

    Extreme Weather Performance

    EPDM remains flexible in sub-zero temperatures and resists degradation in extreme heat. Oklahoma's swings from single digits to 110°F+ are no problem for a properly installed EPDM system.

    Proven Longevity

    25–30+ year service life with proper maintenance. The longest-performing EPDM installations have been in service for 40+ years.

    UV & Ozone Resistance

    EPDM's rubber compound naturally resists ultraviolet radiation and atmospheric ozone — the two biggest enemies of roofing membranes.

    Cost-Effective

    Typically the most affordable commercial flat roofing option per square foot, delivering excellent long-term value.

    Low Maintenance

    Requires less maintenance than many competing systems. Regular inspections and periodic seam checks are usually sufficient.

    Installation Flexibility

    Available in fully adhered, mechanically attached, or ballasted configurations. Large sheets (up to 50 feet wide) mean fewer seams and fewer leak points.

    Maintaining Your EPDM Roof for Maximum Life

    EPDM is a low-maintenance system, but low-maintenance doesn't mean no-maintenance. The property owners who get the longest life are the ones who invest in regular inspections and address minor issues before they grow.

    Inspecting seams and adhesive bonds for signs of separation or lifting
    Checking and recaulking penetration seals around pipes, vents, and HVAC curbs
    Clearing drains and gutters to prevent ponding water
    Monitoring for shrinkage — EPDM can shrink slightly over time, pulling flashings and creating stress at edges
    Documenting condition changes year-over-year to track aging and plan ahead

    Our maintenance programs handle all of this on a scheduled basis, giving you predictable costs and confidence.

    EPDM Repair Services

    Common EPDM repair needs include seam separation, flashing pullback from shrinkage, punctures from foot traffic or debris, and deteriorated caulking at penetrations. The good news is that most EPDM repairs are straightforward and affordable when caught early.

    Our repair crews use manufacturer-approved EPDM patches, primers, and adhesives to make lasting repairs. If your EPDM roof has more extensive damage, a roof coating restoration may be a smart option before considering full replacement.

    Is Your EPDM Roof Reaching End of Life?

    EPDM roofs don't usually fail all at once. They age gradually, and the signs are visible during inspections long before catastrophic failure. Indicators include:

    Widespread surface cracking or crazing
    Significant shrinkage pulling flashings away from walls and curbs
    Adhesive bonds failing across large areas
    Saturated insulation beneath the membrane
