Roofing contractors specializing in single-ply roofing for commercial properties
Thermoplastic Polyolefin is one of the most popular commercial roofing options. It’s inherently more flexible than thermoset membranes and offers the advantage of being reheated, softened and shaped to any size or shape that best fits your commercial building. When it hardens after cooling, you’re still able to change it if there are any redesigns. In contrast, thermoset membranes harden after one heating & cannot be reshaped.
Thermoplastic or EPDM Roofing?
EPDM has always been the standard for commercial flat roofing, but TPO (thermoplastic) roofing has been gaining popularity in recent years. So which one is the preferred industry choice? EPDM typically has a dark surface, which means in sunny climates will absorb heat and force cooling systems to work overtime. TPO roofing reflects sunlight, meaning it’s easier on cooling and HVAC units, saving energy and money. However, EPDM’s synthetic rubber surface will better protect roofs from bad weather like hail and sleet, while a hard thermoplastic roofing system may compromise the building’s membrane when struck by hail.
TPO can ostensibly last longer than EPDM, but it can cost more to maintain in the long run. EPDM is easier to install and repair compared to TPO: thermoplastic roofing systems need to be welded on, and while that makes it extremely durable, it can also be complicated to fix since it requires an electrical source for repair work.
Both roofing systems are excellent choices at protecting your commercial building in southeast Wisconsin. If you’re interested in installing a TPO or EPDM roof on your commercial building, contact Alois Roofing today to get a quote!
