Ethylene Propylene Diene Monomer (EPDM)


No other roofing membrane withstands the weather like Ethylene Propylene Diene Monomer (EPDM).

Key Features

  • Weatherability / durability of the sheet — the longest lasting membrane

Additional Features

  • Flexible application:
    • Ballasted — loose-laid membrane that is held in place with stone
    • Mechanically attached — secured to the roof deck with mechanical fasteners
    • Fully adhered — glued directly to the roof insulation
  • Can be used on both new and existing roofs


  • Does not hold up well to oil, grease or animal fats
  • More difficult to install in cold weather (below 32 degrees)
