The Pros And Cons Of PVC As A Roof Material
PVC seems to be everywhere these days. It remains a popular choice for plumbing. PVC fences are becoming even more commonplace. And now, more roofers seem to be using PVC as a roofing material. If you're in need of a roof replacement, you may be wondering whether PVC is a good material to choose. Here are some pros and cons to weigh in the coming weeks.
Pro: PVC is virtually waterproof.
PVC roofing comes in thin sheets that your roofer can unroll and glue to your roof deck. The material itself is waterproof, and because of the way it is adhered, the seams are virtually waterproof, too. If you live in a really wet environment and are worried about roof leaks, PVC can give you some peace of mind.
Con: PVC does require a strong, uniform roof deck.
Your roof deck does need to be in good shape to install PVC. Any exposed nail heads or penetrations from the roof deck may rip the PVC and make it less effective. So, if your roof deck is older, your roofer may need to do some work on it to make it suitable for PVC roofing. This can make your roofing job more time-consuming and more costly.
Pro: PVC roofing doesn't attract moss, algae, or insects.
Moss and algae are common concerns on tile and shingle roofing. Then with a wood roof, you have to worry about termites, carpenter bees, and other pests. With PVC roofing, you do not need to worry about any of these things. Algae and moss won't grow on PVC. Insects don't eat it or nest in it, either. This cuts down on the maintenance you have to do over the years. You'll never have to apply fungicide or herbicide sprays.
Con: PVC roofing is not easy to repair.
This roofing material is pretty tough and does not break down easily. However, if your PVC roof does develop a tear or a hole, it is not that easy to fix. A roofer will need to remove the entire damaged sheet of PVC and apply a new one. They have to apply the adhesive very carefully to ensure the new roofing sticks to the old roofing properly.
PVC roofing certainly has its place. It works well in wet areas and for homeowners who want a low-maintenance option. Just make sure you are prepared to have work done on your roof deck and to pay a bit more if you need repairs.
