6 FAQs About Thermoplastic Olefin Roofing

If your business has a flat roof, one roofing option you must consider is thermoplastic olefin roofing material or TPO. This rubberlike material is great for flat roofs, but if you aren't sure yet, check out these six frequently asked questions.

What Are They Made From?

In short, TPO roofs are made from ethylene propylene rubber. Basically, this means that rubber, ethylene and propylene are mixed together to create the roofing material. This is known as the membrane. Some other materials are added too, such as fiberglass, but in much smaller quantities. The combination of all these materials creates a membrane that is rubberlike but extremely durable.

How Are They Made?

The downside to TPO roofs is that there is no single recipe for the mixture. This is because TPO roofs are still relatively new, so the formula hasn't quite been perfected yet. Everyone who offers TPO roofs has their own formula. This means that one TPO roof may be completely different than another. In fact, depending on the formula the roofers use, the durability may be affected. This is why it's important to shop around to find the best fit for your needs. Despite the different formulas, however, there are strict standards that every manufacturer has to follow.

Are They Energy Efficient?

A huge benefit of TPO roofs is that they are energy efficient. The membrane does an excellent job of reflecting the sun's light instead of absorbing it. As a result, you get to use less energy to cool the inside of the building. Some factors do impact how well the roof reflects sunlight. For example, if the formula for the TPO leaves the membrane bumpy or rough, this could lead to a build-up of dirt, which actually absorbs light, making the membrane less effective.

Are They Safe for the Environment?

Thanks to the energy efficient nature of TPO membranes, they are a great option for the environment. By using less energy to cool your business, you don't allow as much dangerous gases into the atmosphere, lowering your carbon footprint. However, TPO roofs are good for the environment in other ways too. For example, TPO doesn't contain chlorine, a dangerous chemical that harms the environment. Plus, TPO membranes are recyclable. An entire TPO roof can be removed, recycled and reused to make a new TPO membrane for another roof.

Are Options Limited?

Unfortunately, the options are limited when it comes to TPO roofs, but that's typically always the case with flat roofs. While you can choose from a seemingly endless amount of options for your home roof, your business options are fewer. However, TPO roofs do still give you some flexibility to create the roof you need. One option you'll have is the color of the membrane. They typically come in white, grey and black. A white membrane will reflect the sunlight better, making it great for warmer climates. On the other hand, a black membrane will absorb more sunlight, making it better for colder climates.

Are They Durable?

TPO membrane roofs are also incredibly durable. Unlike other roofing materials, such as wood and asphalt, the membrane isn't susceptible to bacteria, decay, or mildew. Also, unlike metal roofs, you don't need to worry about possible rust. Another reason TPO roofs are so durable is their flexibility. Because they can stretch and shrink, there is less risk of tears or cracks. With proper care, and depending on where your business is located, your TPO roof could last 25 years or more.

If you need a new roof for your business, consider TPO roofs. They are durable and have amazing benefits. For more information regarding flat roofs, contact a manufacturer like Wespol Metal
