EPDM Roofing System Diagram


Single-Ply Membrane Roofing Systems – EPDM, Elastomeric Polymer Roofing in the Oklahoma City metro area

EPDM is an elastomeric polymer that has been synthesized from ethylene, propylene, and a small amount diene monomer. An EPDM membrane is a cured material and is classified as a “thermoset”. This is simply defined as such that the polymer’s molecular structure is “set” as a result of heating during the manufacturing process. EPDM sheets are available in a variety of colors, and range in thickness from 30 – 90 mils. EPDM membranes can be installed using one of three methods: ballasted with large stones, fully adhered with an approved adhesive, and mechanically attached to the roof deck.


Single-Ply Membrane Roofing Systems – PVC, Polyvinyl Chloride Roofing in the Oklahoma City metro area

PVC or polyvinyl chloride is produced by the polymerization of vinyl chloride monomer. PVC membranes can be non-reinforced or reinforced with glass fibers or polyester fabric. They come in thicknesses ranging from 45 – 96 mils. PVC membranes can be installed by mechanically attaching the membrane to the roof deck. They are then fully adhered with an approved adhesive, stone ballasted, and paver ballasted. PVC membranes do not cure after exposure to the elements therefore remains heat weldable throughout the lifetime of the roof.
