Commercial TPO & PVC Roof Systems

Single-ply membranes such as TPO and PVC are ideal for low slope and flat roofs for residential or commercial buildings. A commercial roof is more likely to use these membranes as they belong to a broad family of roofing membranes. There are specific differences between TPO and PVC in deciding which type of commercial roof to choose. 

There is a difference between TPO and PVC, which are thermoplastic polyolefins and polyvinyl chloride polymers. Roofing materials made of PVC have been widely used in commercial buildings since the 1960s. PVC and EPDM were the two rubber membranes that were originally designed as better alternatives. Due to its flexible, reflective properties and environmental friendliness, TPO combines the benefits of PVC and EPDM.

Where Do They Stand On Durability?

Any purchase decision you make should take durability into account. Depending on their thickness, there is some variation in puncture resistance between PVC membranes. Clients value TPO because of its excellent puncture resistance without needing to be as thick as PVC.

The TPO roof will not shrink as time goes by, but the PVC roof will cause a host of problems over time. PVC is much more durable than its rival when it comes to chemical spills, but both products are resistant to chemical spills. PVC may be the better choice if your roof has a chemical outlet or if there are byproducts of food grease.

What are the differences in color range?

White, gray, and tan are the three colors available for both flat roofing membranes.

If the job is 100,000 square feet or larger, TPO offers a wider range of colors. It is possible that certain colors are subject to different square footage requirements from different manufacturers.

It may be important to consider color if you want your building to be in keeping with your lot’s other buildings or if the overall appearance of your building is important for your business. For instance, some owners of commercial buildings like the idea of installing patina green TPO on the sawtooth areas in order to create the illusion that it looks like copper from a distance.

A building that is exposed to a high degree of sunlight may not see very much of a difference between the two products, as they both have a cooling effect. In general, though, the lighter the color, the less heat it will be drawn by the sun as a result of natural temperature variations.

How About The Problems?

It is true that both products have their flaws, yet standard PVC has the more serious issues. Standard PVC is prone to shattering and shrinking over time in cold climates. There is no comparison between TPO and PVC when it comes to being able to withstand the cold. It is common knowledge that PVC has a lower fire resistance than TPO and that it emits toxic chemicals when it burns, making it a major fire hazard.

PVC burns with toxic chemicals when burnt, which is one of the major concerns with PVC, given its lower fire resistance than TPO for Water Restoration Specialists. There are a few disadvantages to PVC, including a higher price, reduced fire resistance, and the fact that it shrinks over time. Despite being less chemical resistant, TPO is more durable and offers a greater variety of colors.

What TPO has to offer

PVC membranes are more expensive than TPO membranes. Choosing a TPO membrane could be the best option if budget is a concern. Furthermore, TPO is also weather resistant and better at resisting tears and breaks than PVC. There is no need to add plasticizers to TPO in order for it to remain somewhat flexible; in addition, it uses materials that don’t degrade over time, meaning it is more durable over time.

What PVC has to offer

Despite being slightly more expensive than TPO, PVC has some advantages. Unlike other roof membranes, it is not affected by chemicals, oils, or grease and is therefore preferred for restaurants with grease traps and other buildings with exposed chemicals and oil. As a result, it can be easier to install than TPO since it is a little more flexible. In our intense Nashville summers, PVC roofs may be the better option over TPO roofs due to their high resistance to heat and sun exposure.
