There are three types of commercial roofing that are the most common: EPDM, TPO and PVC. These are used to create flat commercials roofs. PVC roofing membranes are incredibly popular since they come with so many benefits, including being able to last 20 years. Here is a guide to PVC roofing and how you can take advantage of the many benefits it has to offer.
Polyvinyl chloride (PVC) roofing is a roofing membrane for use on roofs that are flat. It is single ply and has been in wide use for over 50 years. It generally has two layers, with polyester in between those layers as support. The layers consist of materials that provide flexibility and protection to the roofing membrane.
Perhaps the main advantage of PVC roofing is how durable it can be. The seams are heat-welded, meaning that they are water resistant. In some cases, the seams are stronger than the roofing membrane. Heat welding is a much more durable option than using tapes or adhesives, which are common with other roofing systems.
Wind can wreak havoc on a roof, but PVC roofing is very resistant to wind. Again, this is due to the welded seams. Wind cannot get under the membrane to push out on the materials. PVC roofs are effective even in category 3 hurricanes. If wind is a concern where you live, then PVC might be the best choice.
PVC roofing is very hard to light on fire. This is because the materials that make up PVC roofing are not susceptible to oxidation reactions. This makes this roofing option much safer than others.
With commercial roofing, chemicals can sometimes be an issue. However, PVC roofing is resistant to chemical damage, so that is not a concern. Exposure to harsh chemicals and fumes is not a problem for PVC roofing.
For those who want to be as green as possible PVC is a great option. The membrane will harness solar energy, so it is very energy efficient. Heating and cooling a building with PVC roping is generally more cost effective than other options.
