Choosing the right waterproofing system for a flat roof is very important. The choice is usually made according to the existing support and the needs of the beneficiary. TPO and EPDM single-ply membranes are currently among the most popular commercial roofing CT solutions.

TPO membrane can be installed quickly and easily by a professional roofer, even without removing the old layer of bituminous membrane. It is an elastic membrane that can be easily stretched on large surfaces, regardless of their irregularities.

TPO membrane is installed by hot air welded seams, which ensures a superior strength to any adhesive. In general, you will not need major repairs for at least 30 years from the moment of having a TPO membrane installed on your roof, if the work was done with a sense of responsibility, by a professional roofer.

EPDM waterproofing systems are designed for circulating terraces, non-circulating terraces, flat or low-slope roofs of commercial buildings and industrial halls, hydrotechnical works and can also be used to support vegetal roofs and/or extensive photovoltaic systems. Independent studies on the strength of EPDM roof membranes indicate a service life of more than 50 years, which makes this product the top range of waterproofing membranes and one of the most environmentally-friendly systems currently on the market.

A major difference between the two types of single-ply membranes consists in their potential to influence the energy-efficiency of a building. EPDM membranes are dark, so they will absorb heat in the summer, forcing the HVAC systems to work more for cooling the indoor environment. On the other hand, TPO membranes are light colored, so they reflect sunlight, allowing air conditioners to work more efficiently.
