What Is TPO Roofing Material?
If you’re looking to add a new roof to your property, you might be wondering, what is TPO roofing material? This versatile roofing material combines the benefits of EPDM and PVC. This unique roofing material is composed of three layers: a thermoplastic polyolefin (TPO) base, a polyester-reinforced fabric center, and a reinforcement layer. The most popular TPO roofing material comes in 45mils or 60mils, but some manufacturers make it 80 mils or 90 mils. You can get sheet widths of up to 12 ft. (3.66m). steel roofing
While EPDM and TPO roofing membranes have the same fire resistance ratings, the differences between the two are minimal. Both materials are highly reflective, and TPO roofs tend to be whiter than their counterparts. Hence, whiter roofs are much more energy efficient. However, white TPO roofing materials are not completely maintenance free. In addition to cleaning, TPO roofs need periodic expert maintenance to retain their reflectivity. Roofing contractors and experts should check fasteners and flashing regularly, and they can repair any leaks.
Another advantage of TPO roofing is its flexibility. TPO roofing sheets can be installed easily with minimal overlaps. They are also lightweight, which means that only one layer of roofing material needs to be installed. TPO roofs can be installed using adhesives or direct fastening. TPO roofing is heat-reflective, reducing energy usage during the summer. TPO roofing can last for twenty or more years, which is why TPO roofs are a good investment for commercial and residential properties alike.
One of the advantages of TPO roofing is its low maintenance cost. TPO membranes need to be cleaned regularly, and these maintenance programs can help you get the best possible warranty. However, you should also check with your owner’s manual to be sure. If you don’t have time to install a new roof, consider upgrading to EPDM membranes. They are more energy-efficient and will reduce your monthly energy bills.
In terms of durability, TPO roofing is one of the most durable and energy-efficient materials available. Its white color is highly reflective, which reduces the heat load on the roof and helps maintain a lower temperature than buildings with darker colors. Hence, a building with TPO roofing doesn’t need as much A/C as one with PVC roofing. A TPO roof system that uses GenFlex TPO roofing is capable of staying up to 50 degrees cooler than conventional roofs.
Cost-wise, TPO is comparable to PVC. You can expect to spend anywhere from $5.50 to $8.50 per square foot on a roof made of TPO material. For the same area, a standard flat roof made of PVC would cost between $4.00 and $8.00 per square foot. Moreover, TPO can last anywhere from 15 to 20 years in its current form, making it more affordable than other roofing materials.
As a thermoplastic roofing material, TPO is considered a highly durable material that can last up to twenty years. However, repairs can be necessary due to membrane punctures, seam ripping, and flashing failure. Another sign that TPO roofing needs repair is when water penetrates the building. Once the seams are ripped open, water can penetrate the roofing insulation and the deck below. This will create leaks.
