For over 40 years, the EPDM (ethylene propylene diene terpolymer) rubber roofing membrane has been an appealing choice for commercial buildings with a low-slope roof. It remains a top choice for its proven service life and resilience. Some of the characteristics that are considered when evaluating the EPDM roofing solution are:
- Proven hail resistance (critical in Texas!)
- Flexibility in low temps
- Superior resistance to extreme heat and fire
- High resistance to abrasion, weathering and ozone
- UV Radiation resistance
- Thermal shock durability
- High resistance to wind damage
EPDM roofing systems are one of the most environmentally responsible roofing materials available. Its superior track record and long life mean lower replacement costs translating into fewer building disruptions and reduced impact on the environment. It’s important to note that the initial production of the membrane has a low-embodied energy number.
Another great feature for EPDM systems is that they can be coated with an ENERGY STAR approved coating when designs call for a colored surface. The EPDM surface allows for a robust bond that enables the long-term performance of the product. The amount of energy that is radiated back is particularly high with EPDM roofing systems and this is known as having a high emissivity.
EPDM Installation Options
- Ballasted EPDM
- Mechanically fastened Systems
- Fully-Adhered Systems
EPDM System Facts
The membrane used in EPDM roofing systems is extremely flexible, allowing it to be used in many different applications including low and steep slope roofing. It can also be used in unusual situations like domes, barrels or other geometrically shaped roofs. Additionally, it can be used in exposed or concealed assemblies due to its ability to withstand temperature extremes and resist moisture absorption.
Sheets of membrane are spliced together with either tape or liquid adhesive. The goal is to further protect the structure underneath, and keep out moisture. The solutions used by JDR Commercial Roofing are proven in the numerous installations we’ve completed.
