EPDM Roofing vs. TPO Roofing: A Comparison for Commercial Building Owners
EPDM Roofing vs. TPO Roofing: Thermoplastic olefin (TPO) and EPDM (Ethylene Propylene Diene Monomer) roofing systems are two common options for commercial buildings in Washington. In this article, we’ll contrast EPDM and TPO roofing, highlighting their individual qualities, benefits, and things commercial building owners should keep in mind.
A comparison of EPDM and TPO roofing for owners of commercial buildings
Composition and Material Properties:
TPO is a thermoplastic single-ply membrane, whereas EPDM is a synthetic rubber roofing membrane. Excellent flexibility, weather resilience, and UV reflectance are all features of both materials.
Installation and Upkeep:
Heat-welded seams are frequently used to install both EPDM and TPO roofing systems, resulting in a smooth and water-tight roof surface. Both membranes are low-maintenance and chemically, puncture, tear, and puncture-resistant.
Energy Efficiency:
Reflective EPDM roofing options are available and provide good solar reflectivity. TPO roofing, on the other hand, comes in white or light-colored varieties that provide improved energy efficiency and enhanced solar reflection.
Cost factors:
EPDM roofing is typically less expensive than TPO, making it a cost-effective choice for owners of commercial buildings. However, the price difference can change based on the manufacturer, the difficulty of the installation, and the thickness of the membrane.
Lifespan and Durability:
With the right care, both EPDM and TPO roofing systems can last 20 to 30 years or longer. The roof’s longevity is mostly influenced by environmental conditions, routine maintenance procedures, and membrane thickness.
Environmental Impact:
Because EPDM and TPO roofing systems can be recycled at the end of their useful lives, they are regarded as being environmentally benign.
Seam Options:
Compared to EPDM roofing, TPO roofing has greater sheet widths, which means fewer seams. As a result, there are fewer potential leak locations, which is beneficial for bigger commercial roofs.
The flexibility, weather resilience, UV reflectivity, ease of installation, low maintenance, energy efficiency, extended lifespan, and environmental friendliness of EPDM and TPO roofing systems make them particularly advantageous for commercial buildings. While TPO roofing has fewer seams and better solar reflectance for bigger roofs, EPDM roofing may be more affordable. When deciding between EPDM and TPO roofing systems, commercial building owners should take their unique roofing requirements, budget, and long-term priorities into account. Making an informed choice and ensuring a good roofing installation may both be accomplished by consulting a roofing expert.
