PVC roofs are resistant to chemical damage, fire, wind, and hail. Fat from grease vents in restaurants can easily damage conventional roofs but will not harm PVC roofs, making them an excellent option for the food industry. Likewise, PVC roofs are resistant to fire. They are difficult to ignite and, when they do, they burn slowly and self-extinguish when direct flames are extinguished. Additionally, PVC roofs are resistant to natural factors like wind and hail. Because of their strong welded seams, wind won’t work them loose. PVC roofing material is also puncture resistant, reducing the chances of severe storm damage.
