Single Ply Roofing Systems

EPDM roofs are made from synthetic “rubber” material in either black or white-on-black colors. Membranes are available either with or without internal scrim reinforcement, for durability and strength, and in thicknesses of .045” to 0.90”. EPDM roofs are installed by full adhesion, attached mechanically or secured with ballasts. Seams are secured with butyl-tape technology. Warranties on this type of roof system are available from 10 to 30 years.

FEATURES
Highly popular
Relatively low cost
Readily available material with short lead times
Easily repairable

OPTIONS
Colors – black & white
Thicknesses – .045″, .060″, .072″ and .090″
Fleece-backing

TPO roofs are made from thermoplastic material with internal scrim reinforcement for durability and strength. White colored TPO roofs are popular for solar reflectivity to achieve LEED and Energy-Star certification. TPO roofs are installed by full adhesion, attached mechanically or with ballasts. Materials are available in standard colors of white, gray and tan with additional custom colors available on large projects. Thicknesses are available in 0.45”, 0.60” or 0.80”. Seams are secured by heat-welding. Warranties on this type of roof material are available from 10 to 30 years.

FEATURES
Highly popular when white solar-reflective roofing is desired (LEED & Energy Star)
Relatively low cost
Readily available material with short lead times

OPTIONS
Colors – white, tan, gray standard with many custom color options available
Thicknesses – .045″, .060″, .072″ and .090″

PVC/ KEE roofing systems are single-ply membranes with a plasticized formulation. Each type of membrane has a proprietary chemical mix which gives it unique properties, though all PVC/KEE membranes are scrim reinforced. PVC membranes are based on a polyvinyl chloride chemical composition with additional chemicals which keep the membrane flexible and protect from UV degradation. KEE membranes utilize DuPont Elvaloy to protect against UV damage. Seams are heat-welded, much like TPO. Modern PVC/KEE membranes are often characterized as a premium single-ply method to achieve solar-reflectivity and LEED/Energy-Star compliance. Color options are much the same as TPO, but manufacturers typically offer even more custom options in PVC and KEE formulations. Thicknesses range from 0.36” to 0.80” and warranties are available up to 20 years.

FEATURES
Typically grease-resistant (ideal for restaurants)
UV stable – considered more durable than TPO when exposed to concentrated sunlight
Many manufacturers offer faux rib profiles which look like standing seam metal
