EPDM Roofing

EPDM (Ethylene, Propylene, Diene, Monomer), more commonly called rubber roofing, has been used for over 25 years in both commercial and residential roofing. EPDM is a high performance, cost efficient product for low slope or flat commercial and residential roofs. EPDM is available in both black and white, and is sold in a broad variety of widths, ranging from 7.5 feet to 50 feet and lengths up to 100 feet and comes in two thicknesses .045 and .060. EPDM can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.

EPDM offers:

  • Ease of installation
  • Low cost application
  • Durable, flexible membrane
  • Installed with ordinary hand tools
  • Available in a wide variety of sizes to accommodate any application
  • Highly resistant to heat, alkalis acids and oxygenated solvents

EPDM roofing is usually installed over a recovery board commonly known as fiberboard or for a better performance polyiso insulation board is used. Polyiso insulation comes in a variety of thicknesses to add R-value to the roof structure and is also available in tapered panels to add pitch. Fastening systems for the polyiso come in a variety of sizes depending on the thickness of the insulation panels. They also have different fastening systems for either wood, metal or concrete structures.

EPDM comes available in cured, and uncured. Cured is typically used in sheets to be glued down with bonding adhesive on flat or low sloped areas. Uncured is typically used for flashings to wrap around extrusions such as post or inside and outside corners. EPDM has been used mostly in the cities in commercial high rise buildings, but here on Cape Cod there has been a lot more contractors using EPDM on buildings that have walk out decks where they install rubber roofing under a sleeper system deck. With the tapered roofing panels there is no need to have to taper the floor joist anymore which makes the job more cost efficient by saving the contractor time.
