Things To Know About PVC And TPO Commercial Roofing
Posted on: 28 March 2023
If you're looking for white membrane roofing for your commercial building for appearances or to keep your building cooler, you can choose between PVC and TPO membranes. These look nearly the same, but they're made differently, so they have some different characteristics. Here's how PVC and TPO commercial roofing compare.
PVC Is Usually More Durable
PVC and TPO membranes are made of three layers. The top layer absorbs all the wear, a fabric reinforcement layer is in the middle, and there is a base layer on the bottom. The upper layer on PVC commercial roofing is a little thicker, so it's more durable against foot traffic. PVC is also more resistant to chemical damage and fires than TPO roofing.
Both Materials Reflect The Sun
If you're looking for energy efficiency, you'll probably be happy with both types of membranes. They both reflect the sun and reduce solar warming of your building. You might have the best energy efficiency by choosing a membrane that's smooth so debris, pollen, and dirt don't stick to it easily and block the reflective surface of the membrane.
PVC Membranes Are More Flexible
PVC membranes have a flexible quality that TPO membranes don't have. This could make them easier to install than TPO membranes. However, installation methods are basically the same. Both membranes can be seamed together with a heat welder and fastened or fully adhered to the deck. Being flexible could make the installation go a little quicker since flexibility makes PVC membranes easier to work with.
TPO Membranes Cost Less Than PVC
Cost is usually an important consideration for commercial roofing since some buildings can be quite large. TPO usually has a lower cost than PVC, but there are lower and higher quality materials of each type, so the price varies. Another point that makes TPO roofing more cost-effective is it tends to have a longer lifespan than PVC roofing due to the materials the membranes are made from. TPO stands up better to UV exposure over the years.
Both Require Regular Maintenance
Commercial roofing is usually checked by a roofer one or two times a year so damage to the membranes can be found and repaired before the roof starts leaking. Both PVC and TPO roofing are repaired the same way by patching holes and heat-welding loose seams.
Both materials are durable, so they may not need many repairs. However, since your roof may get foot traffic, you may need to have punctures or cracks filled occasionally over the life of your commercial roof.
A commercial roofer can help you choose between a PVC and TPO roof. Both are good choices, and it may come down to your individual circumstances. The roofer may consider the local climate, the amount of foot traffic on your roof, whether trees hang over the roof, your budget, and the type of chemical and grease exposure your roof has when recommending the right roofing membrane for your building.
