DECADES OF PROVEN PERFORMANCE
As sustainability becomes a priority for environmentalists and building codes, EPDM emerges as the commercial roofing material with the longest lifespan. Backed by over 60 years of field experience, the EPDM Roofing Association (ERA) conducted a study on 28 to 32-year-old roofs. The findings show that all tested aged EPDM samples meet or exceed ASTM minimum requirements for new 45-mil membranes, with an estimated service life exceeding 40 years. This durability stems from minimal plasticizer loss due to UV degradation, keeping the membranepliable and repairable.
WEATHER RESISTANCE
EPDM’s weather ability sets it apart from other single-ply membranes. Rene Dupuis, president of Structural Research Inc., notes, “From a weather ability standpoint—mil for mil—EPDM has proven to be one of the most cost-effective membranes available today.” Its dimensional stability and flexibility allow it to adapt to building movements across various climates. Unlike thermoplastics, EPDM resists ozone, UV radiation, and cold cracking without relying on plasticizes, preventing brittleness over time. Available in thicknesses from 0.045 to 0.090 inches and widths up to 50' x 100', EPDM offers versatile options.
Superior Weathering Performance
UV EXPOSURE
Resists UV radiation without degradation
OZONE
Engineered to resist ozone-induced damage
COLD CRACKING
Maintains flexibility in low temperatures
WIND & RAIN
Stands up to wind uplift and heavy precipitation
RESPONSIBLE PERFORMANCE
Environmentally Friendly and Energy-Efficient
Recent U.S. Department of Energy studies highlight EPDM’s alignment with sustainable roofing needs. In certain U.S. climate zones, dark-colored EPDM roofs save more energy than white thermoplastic membranes, challenging the universal appeal of cool roofs. Samir K. Ibrahim, director of design services at Carlisle SynTec Incorporated, emphasizes, “The key factor should always be the amount of insulation utilized in the assembly, which has been demonstrated as the most influential component by which sustainability can be achieved.” This suggests that EPDM’s performance can be optimized with proper insulation, enhancing its eco-friendly profile.
ENERGY EFFICIENCY
Dark EPDM can reduce energy use in specific climate zones compared to thermoplastics.
ENVIRONMENTAL IMPACT
Long lifespan and recyclable materials contribute to a lower environmental impact.
SUSTAINABLE CHOICE
EPDM supports green building goals with durability, recyclability, and energy savings.
LONG-TERM VALUE
The Benefits of EPDM Roofing
Incorporating this content on your webpage highlights EPDM’s durability, cost-effectiveness, and environmental benefits, making it an attractive option for commercial roofing clients. Studies, such as those from the ERA and the U.S. Department of Energy, support EPDM’s lowestlife-cycle cost, demonstrating that a single roof replacement can last over 40 years. By spreading the initial investment over this extended period, EPDM proves to be a cost-effective solution, reducing long-term maintenance and replacement expenses. These findings empower your roofing business to showcase a reliable, sustainable product backed by scientific evidence.
