What is PVC Membrane Roofing Material?
PVC, or Polyvinyl Chloride, is perhaps the most popular single-ply roofing material for commercial projects. The highly durable white membrane has been around since the 1960s. Not only is PVC the oldest single-ply roofing material, but it is also the most time-tested. Furthermore, the PVC membrane is highly flexible, perfect for flat or low-sloped roofs and complicated roof systems.
Polyvinyl Chloride, or PVC roof material, is a product of polymerizing vinyl chloride monomers. It is made of chlorine from salt (which is sodium chloride) and ethylene from natural gas (which contains ethane). PVC flat roof materials are thermoplastic like TPO but are typically more durable than a TPO membrane.
Advantages of PVC
Compared to other roofing materials, PVC’s most significant advantage is its durability. Properly installed PVC roofs can last decades against strong winds, rain, fire, and the sun’s rays. Those in and around Tennessee know the importance of strong roofs to withstand winds! In addition, not only is PVC resistant to fire, chemicals, grease, punctures, and more, but it is infinitely recyclable.
Another eco-friendly feature of PVC membranes is their ability to reflect solar rays due to the white material. As a result, it regulates building temperatures and decreases energy consumption.
Roofing PVC typically costs around $12 – $17 per square foot.* But even though PVC is not the cheapest roofing material, it may save you more money over time. Plus, the fact that PVC roofs are easy to install and simple to repair can further save you money.

PVC Installation in Tennessee
After clearing and cleaning any existing roof, a professional like Austermiller in Tennessee will install the insulation and make sure there are no gaps for maximum energy efficiency. There are three main types of insulation we may use:
- Polyisocyanurate (Polyiso or ISO) – Polyiso is more expensive but has a high R-value, which is the measurement of the material’s ability to resist heat flow. The R-value can range from 4-R to 6-R. Therefore, Polyiso can further reduce energy costs in tandem with PVC.
- 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.
- 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./li>
Next, we will cover the insulation by unrolling and attaching the PVC membrane with adhesive or mechanically. While adhesion is an option, most contractors like us recommend a mechanical application using plates and screws. Once the entire roof is covered, we will weld the seams together with a hot-air gun to create water resistance.
With proper installation and maintenance from a professional roofer, PVC roof systems can last 30 years. Thankfully, roof repairs are quick and simple. But, for a durable, long-lasting roof, always hire a professional at Austermiller for every repair and installation. High-quality PVC commercial roofing installation and maintenance from us will prevent headaches and costly repairs.
