Thermoplastic polyolefin (TPO)
Thermoplastic polyolefin (TPO) is the fastest-growing segment of the commercial roofing industry. TPO membranes are single-ply roof membranes constructed from ethylene propylene rubber. It is well suited for the weather conditions in Shreveport Louisiana. TPO roofs are designed to combine the durability of EPDM rubber with the proven performance of hot-air weldable seams. They have been tested as having excellent resistance to ozone, are algae-resistant, environmentally friendly and safe to install. The material’s manufacturers are so confident in properly welded seams that the material is sometimes advertised as a monolithic (seamless) roof. Seam strengths are reportedly 3 to 4 times those of EPDM’s adhesive and tape seams.
Thermoplastic polyolefin is highly resistant to tears, impacts, and punctures with good flexibility to allow for building movement. Thermoplastic polyolefin are available in white, light gray, and black with thicknesses of either 45 mils (.045″) or 60 mils (.060″). The width of the membrane depends on the manufacturer but they usually come in widths of six to six-and-a-half feet and are one-hundred feet in length.
Thermoplastic polyolefin membranes are installed fully-adhered, mechanically-attached or ballasted. Fully-adhered means that the roof is “glued” to the substrate using a special adhesive. What actually happens is the glue creates a chemical bond with the membrane.
Ballasted simply means the membrane is loose laid over the top of the roof, sealed at all penetrations and around the perimeter, and then a ballast is put on it to hold it in place. Ballast usually consists of smooth, round, river rock 2″ – 3″ in diameter and is applied at a rate of 1,000 to 1,200 pounds per roof square (100 sq. ft.). Sometimes concrete pavers are used in their place. These average 20 pounds per square foot. Mechanically-attached membranes are those that use some type of special screw-type fastener to secure it. The type of fastener will depend on the type of substrate but all fasteners are generally screw-type fasteners. Call Alpine Roofing in Shreveport Louisiana for a free professional quote.
