EPDM vs. TPO Roofing: A Comparison for Commercial Building Owners
Thermoplastic olefin (TPO) and EPDM (Ethylene Propylene Diene Monomer) roofing systems are two common options for commercial buildings. In this article, we’ll contrast the advantages, special traits, and recommendations for commercial building owners of EPDM and TPO roofing.
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:
In order to create a smooth and water-tight roof surface, heat-welded seams are frequently used when installing both EPDM and TPO roofing systems. Both membranes are low-maintenance and chemically, puncture, tear, and puncture-resistant.
Efficiency in Energy:
Reflective EPDM roofing options are available, providing good solar reflection. TPO roofing, on the other hand, comes in white or light-colored varieties that provide improved energy efficiency and enhanced solar reflection.
Cost factors to consider
Generally speaking, EPDM roofing is less expensive than TPO, making it a wise 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.
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.
EPDM and TPO roofing systems offer unique advantages for commercial buildings, including flexibility, weather resistance, energy efficiency, low maintenance, and environmental friendliness. While EPDM roofing is generally more budget-friendly, TPO roofing provides better solar reflectivity and fewer seams for larger roofs. Commercial building owners should consider their specific roofing needs, budget, and long-term priorities when choosing between EPDM and TPO roofing systems. Consulting with a roofing professional can help make an informed decision and ensure a successful roofing installation.
