If you are considering a new roof for your commercial building, you must consider thermoplastic olefin roofing or TPO for its many benefits. If you are considering a new roofing material, but you aren't sure if TPO is right for your building, check out these three frequently asked questions.

What Is TPO Made From?

TPO is a special type of rubber called ethylene propylene rubber. In simple turns, it's a rubber made from a mixture of ethylene and propylene. Other materials may be added, such as fiberglass to give it additional properties. Ultimately, however, most TPO roofs end up as a rubberlike membrane that covers the roof, protecting it from the elements. The downside to TPO is how it is made. There are no regulations on how to make TPO because it is still a relatively new material. Therefore, different companies have different mixtures, so one roof may not be as quality as another.

Are They Durable?

One reason people choose TPO for their commercial buildings is the durability. Wood and asphalt are prone to decay when exposed to moist environments. Moss, algae, and mildew may even start to grow. Metal roofs may become scratched and rusted if not well-maintained. TPO roofs, however, are durable in wet environments. The membrane is also good at stretching and shrinking in the heat and cold, which causes less damage. Depending on the location of your building, your roof may last up to 25 years or even longer with proper care.

Are They Environmentally Friendly?

If you like making business choices that are better for the environment, TPO can help. The membrane is incredibly energy efficient at reflecting the sun's natural light. Therefore, you use less energy during the hot months to cool the building. This is cheaper for you, and it means fewer emissions. White TPO roofs do a better job at reflecting the sun, and if they become dirty, they may absorb more. TPO is also safe for the environment because no dangerous gases are emitted during its process. Plus, when your TPO roof is removed in the future, the entire thing can be recycled to make a new roof.  

When it comes to flat business roofs, TPO is a great choice because of its many benefits. You may be able to reduce your cooling costs and help protect the environment. For more information, contact a commercial roofing contractor in your area today.
