Thermoplastics are a single-ply roofing membrane commonly used on flat or low-slope roofs to keep water from entering the building. Based on polymers, the material is known for its ability to be repeatedly heated and cooled, offering a flexible, lightweight and affordable alternative to hot asphalt.
First used as a roofing material in Europe in the 1960s, thermoplastic roofing products didn’t surface in the United States until a decade later. Since then, it has been made popular by so-called “big-box” retail construction, and is considered ideal for second-generation (roof-over) applications and so-called “cool roofs.”
Of the five common types of thermoplastic membranes, the most widely used are polyvinyl chloride and thermoplastic polyolefin, also known by the acronyms PVC and TPO. Though each has unique benefits, TPO and PVC offer many of the same advantages.
- Sound Investment: The factory-made sheets range in thickness and size — 40 to 100 mils (thousandths of an inch) thick and six to 12 feet wide – and are welded together, often using hot air to create a continuous membrane that is easy to maintain and repair. Thermoplastics also provide better UV protection than many conventional roofing systems, making it a popular option in hot and dry climates. In fact, some manufacturers claim PVC and TPO can reduce a building’s cooling costs by 30%, or more.
- Excellent Durability: Thermoplastic membranes are resistant to tears and many chemicals, and remain flexible as they age. Welding the sheets together creates exceptionally strong seams.
- Environmentally Friendly: Thermoplastic roofs can be a cost-effective step towards an environmentally-friendly building. Some manufacturers claim the materials can reduce roof surface temperatures by as much as 70 degrees.
- Warranties: Because warranties vary depending on product and manufacturer, ROOFCORP has built strong relationships with leading manufacturers such as GAF, Versico and Carlisle SynTec Systems. Guarantees offered by these established Manufacturer’s can run up to 30 years (and in some cases longer) and often can be supplemented with additional coverage.
ROOFCORP’s associates are specially trained to install thermoplastic roofing systems, ensuring the best quality and workmanship and results that last for years to come. In fact, it is the most commonly requested roofing system by ROOFCORP clients.
