TPO Roofing Material

TPO or Thermoplastic Polyolefin is a type of roofing material that is widely used by contractors and homeowners. It belongs to the family of rubber roof materials and is is made from a combination of ethylene-propylene rubber and polypropylene. What TPO roofing systems bring is a powerful yet environmentally friendly protection that can withstand several factors in the environment.

What is TPO Roofing Material?

Thermoplastic Polyolefin or TPO is a single ply roofing material and is considered one of the fastest growing commercial roofing materials. It has gained acceptance in the roofing material industry because of the beneficial characteristics of TPO and all the advantages that its installation allows. Since TPO is made with a single ply roofing membrane, it can provide excellent resistance against UV rays, ozone and chemicals which will answer the demands for roofing systems with the capability to boost energy efficiency and reflection of heat.

There are three types of application for TPO roofing materials – fully adhered, ballasted or mechanically fastened. In the application of TPO roofing systems, the seams of the membranes are welded together firmly by hot air which forms a strong bond between the sheets that’s also waterproof in nature. When compared to EPDM (Ethylene Propylene Diene Monomer) roofing systems, TPO seams are known to be stronger about three to four times that EPDM. TPO is also a great choice for those who want to keep a “green” approach to their roofing as no plasticizers are utilized in making TPO. Furthermore, TPO doesn’t degrade or decay even when under UV radiation. Today, TPO roofing systems are commonly available in white, gray or black.

TPO is made into sheets by using a mixture of polypropylene and ethylene propylene polymers plus polyester. No plasticizers or chlorine are used in making TPO, allowing it to gain its remarkable environmental friendly characteristic. The formulation of TPO includes reinforcement with a polyester fabric and made by using a UV resistant thermoplastic polyolefin formulation. TPO roofing systems may come in a variety of thicknesses that depends on the manufacturer. With the manufacturing process of TPO roofing systems, it leads to the creation of a commercial roofing system that exercises reliability, energy efficiency, convenience, environmentally friendliness, cost effectiveness and an easy installation process.

What are the Benefits of TPO Roofing Material?

TPO roofing systems are known for their environmental friendly build. They are commonly used as low slope single ply roofs in many homes and made from polypropylene and ethylene-propylene rubber.

Here is a list of benefits that thermoplastic polyolefin is known for:

  • The most environmentally friendly roofing material that is a single ply system
  • Offers great flexibility even during low temperature conditions
  • Has great resistance against puncture injury
  • Reduces heat island effect on the roof
  • Strong seams
  • Decreases the rise of solar heat within the material
  • Comes with Cool roof Energy Star System, providing resistance from UV rays
  • Lowers heating and cooling bills
  • Resistant against many types of substances (ex. chemicals, salt, acid, oil, etc.)
