EPDM Roofing Systems


  • Membrane: Nonreinforced, cured EPDM (ethylene propylene diene monomer).
  • Factory Inseam Tape: For superior quality assurance and labor savings compared to field fabricated seams.
  • Fully Extruded: Produces fewer air voids, more uniform thickness and smoother sheets.
  • Vulcanization Process: Combines two layers of membrane to produce a fully cross-linked monolithic membrane.
  • Membrane Formulation: Performs in extreme temperature climates and withstands differential movement (elongation).
  • UV-Stabilization Properties: Offers outstanding ozone and weather resistance delivering one of the longest service lives available.
  • Technical Expertise: Backed by 30+ years of EPDM experience and installations.
