TPO, or thermoplastic polyolefin, is a heat-reflective and energy-efficient single-ply roofing material. If you’ve ever seen a dazzling white roof, you’ve probably seen TPO roofing.
TPO boasts some of the highest energy savings for single-ply membrane roofing
If you’re looking for an energy-efficient and cost-effective flat roof system, TPO is one of the best options you’ve available in the market.
In this article, we’ll go over everything you need to know about TPO roofing.
Material and Types
TPO is a single-ply roof system, which implies that just one sheet (or membrane) of TPO is placed on the roof. It comprises three layers: a thermoplastic polyolefin base layer, a polyester-reinforced fabric middle, and a thermoplastic polyolefin top layer.
Each thermoplastic polyolefin layer is constructed of ethylene-propylene rubber and is filled with talc, fiberglass, and carbon fiber. These filters increase the strength and flexibility of the TPO.
The reinforced polyester middle layer gives the TPO membrane even greater flexibility and allows it to be easily rolled out onto the roof.
TPO has been a go-to option for businesses and homeowners for various reasons, including its color palette, aesthetic feel, and its energy-saving possibilities. Another advantage is its versatility in thickness and breadth, which allows it to be used in a broader range of applications.
TPO roof membranes are made to fulfill various application and design requirements. TPO is commonly linked with white; however, TPO membranes can be white, grey, or black.
Thickness and Width
TPO roofing casings are also available in a variety of thicknesses and widths. With a broader range of alternatives, you can better select the type that is most suited to your application situation.
Commercial grade TPO has a thickness of up to 0.080 inches and is available in 3-foot-wide or 12-foot-wide rolls, whereas residential TPO has a thickness of 0.045 inches to 0.060 inches and is available in 6.5-foot-wide 100-foot-long rolls.
Advantages and Disadvantages of TPO Roofing
TPO roofing is still a relatively new product in the world of roofing materials, so it’s advised to be cognizant of both its pros and cons.
Pros of TPO
TPO roofing membranes are very flexible, making them more resistant to rips, punctures, and damage caused by building movement and settling. TPO can also withstand UV damage and chemical exposure is eco-friendly. This feature also significantly reduces your HVAC expenditures in hot weather.
Cons of TPO
The main disadvantage of TPO is that it is a new product in roofing and construction materials. Another critical issue developing from a defective TPO product is seam failure. Even though TPO roofing can withstand a lot of heat and even cut your cooling expenditures in the summer, the most durable TPO membranes have high welding temperatures.
You can ensure that you get the most out of your TPO roof by selecting the most refined product and roofing contractor. However, it is imperative to pick the right combination of TPO thickness, color, and material for your roof installations.
