TPO Commercial Roofing

TPO polymers are blends of EBR (polypropylene plastic or polypropylene and ethylene propylene rubber) and EPDM (ethylene propylene diene terpolymer rubber). Before it is formed into a membrane, other additives are added to the mixture. The membrane is then attached to the roof board with fasteners. When combined with several other elements (like a weathering package, fire retardants, and insulation), the TPO membrane becomes a part of an entire roofing system.

TPO membranes are produced by calendering with lamination, extrusion with lamination, or extrusion-coating techniques. Polypropylene and ethylene propylene polymers are combined to make TPO sheets and usually are reinforced with polyester. TPO sheets contain colorant, flame retardants, UV absorbers and other proprietary substances to achieve desired physical properties.

TPO is one of the newer roofing systems and has quickly climbed in popularity. TPO is designed as a combination of EPDM (rubber) and PVC (polyvinyl chloride). Its flexibility, strength, and resistance to harsh temperatures and wild weather. TPO roofing has many advantages, but it doesn’t have a long track record compared to more traditional roofing systems.

TPO Roofing Systems

TPO is favored due to its strength, ease of installation, and longevity. TPO can be heat-welded during installation because of its material’s thermoplasticity, which is a huge advantage since seams are usually the weakest part of a roof. In fact, TPO seams are said to be 3-4 times stronger than EPDM systems and 6 times stronger than systems that use glue seams or tape systems! They are resistant to chemicals, do well in high heat, are flexible in cold temperatures, and are generally quite affordable. TPO systems can last 10-20 years, with proper installation and maintenance . TPO systems are also environmentally friendly, making them an even better choice for your roof.

These systems don’t degrade under UV radiation, contain no plasticizers and come in white (which reflects heat, helping the building stay cool). Plus, TPO can be made from some recycled materials! It is the perfect choice for your “green” building.

TPO does have some cons, like other roofing systems. Most of its downfalls are because it is still so new. It is not time-tested, and doesn’t have the reliable reputation that some other roofing systems have. The strength of any roof (TPO especially) depends greatly on the quality of installation. If you choose a reliable roofing contractor and get your yearly maintenance checks taken care of, you shouldn’t have any problems when choosing a TPO roofing system.
