What is Thermoplastic Roofing?Thermoplastic Polyolefin Roofing Installations In Milwaukee, Wisconsin

Thermoplastic polyolefin (TPO) is a single-ply system most often used in low-slope and flat roofing. TPO roofing membranes come in single squares of varying widths. It is most commonly used for flat roofs due to its ability to cover large areas effectively and be shaped or formed to any size roof. During the summer, heat will cause TPO to expand and will adjust to the surface of the roof as it changes. On the opposite end, it will harden during winter, providing a tighter seal that will block snow and water from seeping through. TPO is able to resist dirt, moisture, and mold better than other forms of single-ply roofing materials. 

TPO membrane is made up of three bonded layers:‍

  • Thermoplastic polyolefin base layer
  • Polyester-reinforced fabric center
  • Thermoplastic polyolefin top layer

Benefits of TPO Roofing

  • Resistant to shrinking and cracking
  • Stands up well to UV rays
  • Cost-effective
  • Flexibility allows for easier installation
  • Doesn’t need much maintenance
  • Environmentally friendly (No dioxins, chlorine, or other hazardous materials are used in making them and they are completely recyclable)
  • Installed by adhesion, mechanical attachment (screw-in fasteners), or ballasting (such as river rock)

Thermoplastic or EPDM Roofing?

TPO roofing is challenging EPDM's (Ethylene propylene diene monomer) long-standing dominance in commercial flat roofing due to its energy-efficient reflective properties. So which one is the preferred industry choice? While EPDM offers robust protection against harsh weather, TPO boasts longevity and lower energy costs. However, TPO's installation and maintenance costs may be higher compared to EPDM. Both options are viable for commercial buildings in southeast Wisconsin.

Frequently Asked Questions

How is TPO roofing installed?

Before TPO is laid down, insulation must first be installed to provide a surface for the TPO to adhere to. Once the insulation is installed the welding process can begin, using a heat gun the contractors weld the seams together providing a tight seal.

What is TPO roofing made of?

Thermoplastic polyolefin roofing is made up of a rubber called ethylene-propylene. To increase the durability and flexibility of TPO talc, carbon fiber and other materials are added as fillers.

How much does TPO roofing cost?

Since all roofs come in different shapes and sizes, the price of TPO roofing installations can differ. Depending on the size and shape of your roof a typical TPO installation can cost anywhere from $7,000 to upwards of $12,000.

How long will a TPO roof last?

TPO roofing is relatively new in the roofing industry so some of the oldest TPO roofs are around 20 years old. But with proper maintenance and regular inspections, TPO roofs can last for 30+ years.
