EPDM and PVC are both popular single-ply roofing membranes for flat or low-slope roofs, each with distinct advantages. EPDM, a synthetic rubber membrane, offers excellent durability and longevity, with a lifespan of 30 years or more when properly installed2. It's highly resistant to UV radiation, extreme temperatures, and environmental stressors1. EPDM is typically black, absorbing heat, which can be beneficial in colder climates for passive heating2. PVC, on the other hand, is a thermoplastic material that provides superior durability and performance compared to EPDM1. It features hot-air welded seams, creating a stronger and more watertight bond13. PVC is highly resistant to chemicals, making it ideal for restaurants and industrial facilities1. It's usually white, reflecting up to 90% of UV rays, which enhances energy efficiency and reduces cooling costs
