Thermoplastic polyolefin roofing, often abbreviated TPO) is an effective roofing option for many commercial buildings with flat roofs. In fact, across the United States, there are more TPO roofs on commercial buildings than any other option. While it used to be, business owners could expect to get about 25 years from this type of roofing. Thicker options have raised averages substantially.
TPO roofing comes in sheets measuring from 8 to 20 feet wide, and it can be custom cut to fit your flat roof’s size. The name is a little misleading because plastic is not used to make this roofing. Instead, manufacturers make it with different types of rubber. Roofers apply it with hot air welds, so you need to be sure that you are working with a professional roofer in Longwood, like Dehlinger, to have this roofing material applied or it will leak.
There are many different advantages of TPO roofing depending on your unique circumstances. It receives a Class A fire rating from the Underwriters Laboratories when manufacturers add fire-retardant chemicals during the manufacturing process, which may help you save money on your commercial insurance. These roofs are usually white, so they do a great job of reflecting the sun helping to keep interior temperatures cooler.
You have a choice of many different insulations with TPO since the insulation is not attached to the roofing material. Many business owners choose to go with polyisocyanurate (Polyiso) insulation because it offers a decent R-value while being cost effective. If you want to raise the R-value, consider extruded polystyrene as it provides a better R-value per dollar spent. At the top of the line is expanded polystyrene, which provides an exceptional R-value and will not retain moisture, which may help keep your roof from leaking.
Like all products, there are some disadvantages to TPO roofing. It is a single-membrane roofing material, which can cause roofs to leak more quickly than if you have multiple layers. Therefore, you should be sure to choose thicker options that are less likely to be penetrated. Since it is a single-membrane roof, it is easier to find leaks. Therefore, repair costs are often lower.
