For over 50 years, EPDM has continued to be one of the most frequently used roofing materials on the market. Architects, consultants, and engineers continue to specify EPDM as a high-performance and energy-efficient roofing system. Proven performance in even the toughest weather conditions has made EPDM a dependable and versatile choice. With built-in UV protection and thermal shock durability, the sun beating down on your home or business can’t penetrate it. And EPDM is ozone resistant, too. Plus, when the weather becomes frozen, it keeps its flex and even protects your building in high winds and hail. Not only does it resist deterioration after decades of on-the-job service to you, EPDM has an expected life expectancy of over 50 years. it has superior tensile strength, and when it’s time for replacement, offers a fully recyclable membrane.
Strong, with a Sensitive Side
EPDM is a synthetic rubber elastomer, manufactured for superior strength and flexibility. It also provides an impervious surface that doesn’t pollute rainwater runoff, making it an environmentally sound roofing choice. Additionally, EPDM is fire resistant, recyclable, and economical, qualifying building owners for LEED points and meeting ASTM standards for new membranes.
Beauty is Only One of Many Benefits
EPDM’s ability to withstand all types of weather conditions makes it a standout in locations that experience wide temperature fluctuations. It resists ozone deterioration and offers one of the highest tensile strengths of any membrane in the industry. It looks good, too. EPDM is available in a variety of thicknesses and provides a smooth and aesthetically pleasing finish. Black EPDM is a smart choice in cool climates to reduce facility-heating costs.
EPDM can be mechanically fastened, fully adhered, or ballasted. Wide membrane widths mean fewer seams and increased efficiency during installation. It’s suitable for installation on new roofs and reroofing projects.
Repair and Restoration
One of the unique attributes of EPDM is its ability to be easily repaired and restored—an attribute not shared by all roofing systems. Even after years of in-field service and exposure to the elements, repairs or modifications involving the installation of a new roof curb into an aged roof can be accomplished easily, with the expectation of long-term performance.
Unlike other roof systems that may degrade and become brittle over time from ultraviolet exposure, EPDM maintains its integrity and flexibility. Because of this, EPDM allows for modifications. EPDM roof repair can be as easy as washing the membrane, preparing the surface, and applying the repair material, including coatings.
Another unique attribute of EPDM is its ability to be restored. Aged and damaged EPDM roof systems are now being restored to original installation quality without major costs or disruption to business.
EPDM is one of the most sustainable and environmentally responsible roofing materials used today in the construction industry. Its successful track record of superior overall system performance results in low life cycle costs. Less frequent replacement results in decreased building disruptions and reduced impact on the environment. The initial production of the membrane has a low-embodied energy number (the amount of energy required to produce and implement a product from material extraction, manufacturing, and installation).
