EPDM, ethylene propylene diene monomer (or Terpolymer which is simply a product consisting of 3 distinct monomers). EPDM is classified as a thermoset material which means it is either fully cured prior to being installed or that it cures during natural weathering after installation. EPDM roofs are single-ply membranes meaning there is only 1 ply of roofing material, not multiple plies laminated together. Single ply EPDM is designed for large roofs, such as “Lowe’s”, “Wal-Mart”.
EPDM has been in use on roofs in USA since the 1960’s and is one of the most common types of low-slope roofing materials. That is because it is relatively inexpensive, simple to install, and fairly clean to work with when compared to conventional built-up roofs. There aren’t any odors or fumes that accompany built-up roofs which appeal to many property owners and managers.
EPDM is a rubber material whose principal components consist of the compound's ethylene and propylene. A flexible rubber matrix forms when a small amount of diene is added to the mix. EPDM is available reinforced or unreinforced with both commonly used; it’s also available in either a cured or uncured state. Vulcanized EPDM is the most common with non-vulcanized often used for flashing purposes. One advantage is the seams are spread very far apart; in between 50 by 100 feet sheets. You may use a mechanical fastener, such as tern bar to hold it down, or more common is ballast. That is simply a 2- or 3-inch round rocks placed on top to hold it in place. Then there is the fully adhered system. The problem with this is you typically have to use 10-foot strips to glue, if you are an excellent installer, you may be able to use 20-foot-wide sheets giving the system less seams.
Properly installed EPDM rubber roofs should last between 12 and 25 years.
