PVC is one of the most durable waterproofing options. It is a product that has proven it can serve its purpose for a longer period of time without need for a flat roof replacement. This type of roofing also has an established end-of-life recycling program that converts the old membrane back into roofing membrane products. As with most roofing materials, it is naturally fire retardant and will self extinguish with the removal of the flame source.
Pros and Cons of PVC Roofing Systems
- Strength – PVC roofs are very strong.
- Resistant to chemical damage. Animal fat from grease vents on restaurants can damage an asphalt-based roof and some other single-ply roofs, but it won’t hurt a PVC roof.
- Fire resistance – PVC roofs have a good fire-resistance rating. This can be intensified by using different types of roof insulation under the PVC.
- Great wind uplift resistance. This is important if you live a high wind area or have a high-rise building.
- Not nearly as thick as asphalt-based roof systems making them more susceptible to damage.
- PVC roofs can be very slick, you have to be carefully when you walk, especially if the roof is wet.
- Can stretch or shrink over time (mostly shrink). This causes roof failure. It’s not something that usually happens right away, it takes years and years.
