PVC Commercial Roofing Material

What is PVC Membrane Roofing Material?

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. Polyvinyl Chloride roofing is cost-effective, long lasting, and extremely durable.

PVC also has an option for KEE. PVC is mainly used on restaurants and is the only membrane impervious to grease.

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. 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 — PVC roofs are easy to install and simple to repair, which can further save you money.

PVC Installation in Tennessee

After clearing and cleaning any existing roof, our professionals install insulation and make sure there are no gaps for maximum energy efficiency. There are three main types of insulation we may use:

Polyiso 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.

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.

HD ISO roofing is a type of roof cover board made of high-density polyisocyanurate. It’s a closed-cell, thermoset foam core with a coated glass facer — also known as polyiso, PIR, or ISO.

Once the insulation is covered, we unroll and attach the PVC membrane with adhesive or mechanically, then 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. To start your next roofing project, contact us at Austermiller for a quote!
