EPDM Single Ply
EPDM is an acronym for Ethylene Propylene Diene Monomer, a synthetic rubber. EPDM was first designed by the automotive industry to replace materials used on hose and brake pipes that had a tendency to rot when exposed to extreme temperature and harsh chemicals.
This bio-friendly polymer has been constantly tested and improved for over 40 years and is still the number one choice amongst contractors for repair or replacement roofs. To date, the oldest EPDM roof still in service is on an airport in Chicago, which was installed in 1962.
EPDM roofs are completely cold applied; meaning, no flames or dangerous boilers are needed to install the membranes. If EPDM is prescribed for an existing roof, and there are no rotten timbers or water leaks, EPDM can be applied over the old roof further adding to the security and efficacy of the roofing structure.
EPDM is an elastomeric polymer comprised of clay, carbon, oils, and other curing agents. Because of its components, EPDM is fire resistant, stable, resilient, resistant to Ultra Violet light, flexible, and vulcanized. It is manufactured as a two-ply fabrication that is then laminated as one-ply, and then cured for ultimate stability and durability. This resilience under extreme conditions makes it a prime choice for use in any geographic climate while retaining a wide range of design versatility and application. EPDM can be laid over substrates and weighted down with rocks and gravel or adhered to rigid insulation board attached to the deck of the roof, a more lightweight option.
The most important feature of EPDM is its flexibility. Because of this aspect, it can be used in all sorts of roofing conditions from low-sloped roof decks to steep-sloped barrel roofs to simple to complex roof designs. In comparison to other roofing membranes, the low insulation cost of EPDM and simple adhesive-only installation make it a prime choice for contractors in both new roofs and repair jobs to and over existing roofs.
