Thermoplastic Polyolefin (TPO) Roofing Material

When evaluating your options for the best roofing system to install on your commercial property, it is critical to know the pros and cons of the different roof types you are considering as there are a variety of roofing materials to choose from. The type of roofing material you choose will ultimately depend on a number of factors: the climate of the area where it will be installed, your budget, as well as design and style preferences.

Most commercial buildings feature flat roofing, with the three most popular types of flat roofs being PVC, EPDM and TPO. In this article, we will focus on TPO roofing technology.

What is TPO?

Thermoplastic Polyolefin (TPO) is a single-ply membrane, made from a blend of polypropylene and ethylene-propylene rubber; typically, TPO membranes consist of a top layer, which contains the polymers that give TPO its reflective quality; the scrim – middle layer – which reinforces the rubber and gives it the stability and strength for high performance; and a bottom layer/base. They typically contain performance-enhancing additives such as flame retardants. TPO membranes come in varying thicknesses, with 45-mil-thick membranes being the most popularly used.

TPO roofs have rapidly become the go-to roofing system for commercial properties despite the fact that in comparison with other roofing systems on the market, TPO roofing technology is relatively new, having been introduced to the market in the early 1990s.

Benefits of Installing a TPO Roof

The Thermoplastic Polyolefin roofing system is a popular choice for business owners and property managers due to the many benefits it offers:

  • Durability

The TPO roofing membrane is highly durable and strong, made from resilient compounds. They are flexible membranes, making these roofs resistant to tears and punctures, and able to withstand strong impact. Also, they are resistant to mold and algae growth as well as debris build-up. A TPO roof can last for about 15 – 20 years.

  • Energy Efficiency

The reflective, white surface of TPO roofs minimizes ultraviolet exposure by redirecting UV rays away from your home. This is particularly advantageous during blistering summer days as indoor temperature is reduced which, in turn, boosts energy savings. It is not surprising that TPO roofs have high ENERGY STAR ratings.

  • Costs

When compared with PVC roofs, TPO roofs offer similar benefits, such as maximum energy efficiency and the use of hot-air weldable seams. However, one advantage TPO roofs have over their PVC counterpart is that they are more cost-effective.

  • Easy Installation

TPO roofing sheets are relatively lightweight and easy to install. Also, the sheets have less seams which makes the installation process much simpler.
