PVC is a common flat roofing material. It’s laid in a single, waterproof layer, which is relatively lightweight and flexible. PVC roofing is then heat-welded on to ensure it’s waterproof and strong.
If you need a flat roof but are unsure what material to use, PVC is definitely worth considering. PVC roofing is popular because it’s a highly effective roofing material, but it does have its downsides. To help you make an informed decision, we’ve put together a list of PVC’s pros and cons.
PVC roofing is long-lasting. If it’s installed properly and maintained correctly, a PVC flat roof can last over 30 years.
PVC roofing is durable. It isn’t damaged by extreme weather conditions or UV light. It’s also very unlikely to develop leaks, as attaching PVC by heat-welding makes it waterproof.
PVC roofing is lightweight. This means that it’s suitable for small and relatively weak structures, as well as stronger buildings.
PVC roofing is relatively flexible. This means that it’s suitable for the roofs of buildings that may move slightly over time.
May shrink over time
PVC roofing may shrink slightly over time. While this is quite minimal, it’s worth keeping an eye on, as it may reduce how effective your roof is.
PVC roofing is expensive. It costs more than other flat roofing materials, like felt, asphalt and rubber.
Not environmentally friendly
PVC roofing is not particularly environmentally friendly. Its production can release toxic substances that damage the environment. Despite the existence of recycling schemes, most PVC ends up in landfill, where it also has the potential to release damaging toxins.
