If you are looking to replace your commercial roof, you may be wondering whether TPO or PVC is better. Both are single-ply thermoplastic membranes with similar properties and advantages over traditional built-up or modified bitumen roofs. However, there are some key differences to understand before deciding which is right for your building.

TPO Roofing

TPO, or thermoplastic polyolefin, is a relatively new contender in commercial roofing that's gaining popularity for many good reasons. The white reflective surface can lower cooling costs, and it's resistant to UV rays, ozone, and chemical exposure. TPO is lightweight, easy to install, and available in a variety of colors like white, gray, or black. The seams can be heat-welded together for a watertight seal. Maintenance is minimal and warranties are common from commercial roofing contractors. While not quite as robust as PVC or polyvinyl chloride, TPO still provides excellent performance at a slightly lower cost.

PVC Roofing

Polyvinyl chloride, also known as PVC, is another highly flexible thermoplastic roofing membrane that's been used for several decades. It's available in white, gray, or black or can be custom colored. The formulation includes UV stabilizers and flame retardants for exceptional weathering properties and fire resistance. PVC roofing is chemical and stain-resistant, energy-efficient, and easy to install and repair. Heat-welded seams provide a watertight finish. You can expect warranties to be available from reputable contractors. Of the two materials, PVC is heavier-duty and more tear-resistant.

The Best Choice for You

When choosing between TPO and PVC, you'll want to consider the initial cost, longevity, energy efficiency, fire resistance, and other details like weight and custom color options. TPO is typically more affordable upfront than PVC, however, in our experience, PVC may outlast TPO by five to 10 years. According to Roofer's Guild, most roofs last between 25 and 50 years, although the exact lifespan varies based on roof and property type. PVC is naturally fire retardant and heavier, while TPO requires additional fire retardant treatment and is more lightweight.
