Single Ply PVC Roofing

What is PVC Roofing?

PVC is manufactured from two main components: chlorine and ethylene. Chlorine is a derivative of salt, and ethylene is made from processed petroleum or natural gas. The material is then made into the roofing material by taking to sheets of PVC with a polyester reinforcement in between. Each layer provides more strength to the roofing system.

The bottom sheet is made from black PVC that contains an ingredient known as plasticizers to increase flexibility. The top sheets use plasticizers as well, but also contain additives that make it UV resistant to reduce heat within a building. PVC roofing is considered single ply, but it is available in different thicknesses increasing its resistance to the weather and other elements.

Benefits of PVC Roofing

One of the biggest advantages of having a PVC roof is how strong and durable they are.

PVC roofing is designed from the start to be strong with an ability to withstand a minimum of 350 pounds per inch of force. This is for the thinnest available PVC which means you can get much stronger PVC if needed.

On top of this, when the roofing is installed, the seams are welded together increasing strength even further while ensuring your roof is watertight to stop leaks. This makes it one of the most durable roofing systems as it doesn’t rely on adhesives, caulk, or tape.

PVC roofs are also resistant to fire as it is difficult to ignite and burns incredibly slow with the ability to extinguish itself when the source of a fire is finally removed. With the way it is applied, it has extreme resistance to any uplift caused by excessive wind. This has allowed many roofs to withstand up to category 3 hurricane levels of wind.
