Are TPO Roofs Weather Resistant?

TPO roof waterproofing systems offer a unique combination of features and benefits that have been demonstrated on rooftops around the world. These membranes are made by combining a layer of ethylene-propylene rubber with a layer of polypropylene and reinforced with a polyester insert. The reinforced membrane combines the flexibility of rubber and the heat weldability of thermoplastic material into a sheet with great protective and self-leveling characteristics.

The TPO membrane does not contain plasticizers or flame retardant halogen, which leads to a special resistance to UV radiation (UV radiation is responsible for the premature aging of many other roofing materials). The TPO membranes are white and reflect the sun.  As a result, the temperature of the roof is reduced.

In addition to reducing the energy demand for cooling the entire building, a low roof temperature can also increase the efficiency of a photovoltaic system. In cases where there is a ventilation system, the efficiency of transporting cold air throughout the building is also dramatically increased. This leads not only to low energy consumption, but also to a positive effect on the environment.

The TPO membrane also shows a strong resistance to severe weather phenomena and extreme temperatures (it remains flexible and elastic at low temperatures up to -50 °C).

It has an estimated lifespan of at least 25 years and does not require special maintenance. Talk with one of the Highlands Ranch roofing companies who specialize in commercial roofs for answers on this roofing product and others.
