What is EPDM roofing?
EPDM is a synthetic rubber single-ply roofing membrane commonly applied to flat and low-slope commercial buildings, known for its durability and weather resistance.
EPDM (ethylene propylene diene monomer) is a synthetic rubber sheet membrane installed as a single continuous layer over flat or low-slope roof decks. The material is typically 45 or 60 mils thick and comes in rolls that are seamed together on site. Hartford area commercial buildings, warehouses, and light industrial facilities commonly use EPDM because it handles New England's temperature swings and UV exposure without deteriorating quickly.
The rubber resists cracking and punctures better than older tar and gravel systems. EPDM stays flexible in cold winters and does not become brittle, which matters in Connecticut's climate. The membrane reflects some sunlight, reducing heat absorption in summer, though not as much as white TPO or PVC alternatives. Most EPDM systems last 20 to 25 years with minimal maintenance, making them cost-effective for property owners who want a straightforward roof covering.
Installation involves mechanically fastening the membrane to the substrate or fully adhering it with special adhesives. Seams between sheets are the critical detail in EPDM performance, sealed with liquid adhesives or specialized tape. Penetrations for vents, skylights, or mechanical units require careful flashing to prevent leaks.
