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 90s as an alternative to more expensive rubber and PVC roofs.

The flexible material of TPO membranes is excellent for flat or low-sloped roofs. TPO roofing material is made from recycled materials that are fire-resistant. The material consists of a single layer of synthetics with a reinforcing fabric scrim to stabilize and strengthen.

Advantages of TPO

Contractors and property owners value TPO for being energy efficient and 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 20 feet. The rolls make installation simple, saving time and labor costs.

On average, TPO roofing material costs $3.50 to $7.50 per square foot. However, the material can cost as high as $6 – $12 per square foot.* But when compared to other roofing materials, 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 30 years when well-maintained. Common repairs are for ripped seams, failed flashing, or punctured material. During installation, however, the sheets are welded together using hot air guns. The heat-welded seams are very durable and require little maintenance compared to other seams.

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. Expanded polystyrene (EPS) – EPS has the highest R-value per dollar for insulation and can be used for roof, wall, and floor insulation projects that require contact with the ground. Furthermore, it is water resistant and does not hold onto water over time.
  3. Extruded polystyrene (XPS) – XPS is known for its blue, green, or pink coloring. It is in between other insulation materials in terms of price and performance. XPS is semipermeable, with a perm rating of 1, meaning only a tiny amount of water vapor can pass through the material.

After installing insulation, we attach the TPO membrane to the cover board with adhesive, ballasting, or mechanically fastening 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. Thankfully, TPO material is simple and easy to repair. Most of the time, only the seams need a quick repair.
