TPO Commercial Roofing Material

TPO roofing material for commercial roofs at austermiller in tennessee

What is TPO Roofing Material?

TPO, which stands for thermoplastic polyolefin, is a common single-ply roofing material often associated with commercial roofs. The other common single-ply roofing material is EPDM rubber roofing. However, TPO was created in the late 90s as an alternative to more expensive rubber and PVC roofs.

The material of TPO membranes is excellent for flat or low-sloped roofs. TPO roofing material is made from recycled materials.

Advantages of TPO

Contractors and property owners value TPO for being cost-effective. Generally white, TPO membranes naturally reflect UV rays and decrease the heat absorbed from the sun’s rays. Plus, the flexible material comes in rolls of sheets in 10, 12, and 16 feet. The rolls make installation simple, saving time and labor costs.

TPO is low-cost. As a result, some consider TPO as a suitable rubber roof alternative.

TPO roofs generally last 15 – 20 years and can last up to 30 years when well-maintained. Common repairs are for open seams, failed flashing, or punctured material. During installation, however, the sheets are welded together using hot air guns.

TPO Installation in Tennessee

To begin the installation, we at Austermiller Inc. clean or remove any pre-existing roof materials. Next, we install your choice of insulation for the roof. There are three main types of insulation we may use:

  1. Polyisocyanurate (Polyiso) – Polyiso is more expensive but has a high R-value, which is the measurement of the material’s ability to resist heat flow. Therefore, Polyiso can reduce energy costs.
  2. DensDeck Prime – DensDeck Prime is a gypsum cover board with a pre-primed surface that is used in commercial roof systems. It has a coated glass mat facer on the front and back, and face mat enhancements that allow adhesives to be applied more consistently.
  3. HD ISO – HD ISO roofing is a type of roof cover board made of high-density polyisocyanurate (HD ISO). HD ISO is a closed-cell, thermoset foam core with a coated glass facer. It’s also known as polyiso, PIR, or ISO.

After installing the insulation, we attach the TPO membrane to the insulation with adhesive or mechanically fasten it with screws. Once the TPO is rolled out on the entire roof, we use a hot-air gun to weld seams together.

With proper installation and maintenance from Austermiller Inc. in Tennessee, your TPO roof system can last up to 30 years. Though, you may need minor repairs after 10 to 20 years.
