There are two types of sheet membranes for commercial roofing systems:e thermoplastic (can be remelted) and thermoset (remains in a permanent solid state). One of the most popular thermoset roofing materials today is ethylene propylene diene terpolymer, or EPDM. A durable synthetic rubber membrane used in flat roofs, it contains oil and natural gas ingredients that help enhance its performance. To install these membranes, installers seal the seams using specially formulated tape or liquid adhesives.
EPDM Roofing Benefits
Here are some of the benefits you can get from installing EPDM roofing:
- Weather resistance. Since EPDM is a rubber material, it can resist moisture exposure and general damp conditions. A good choice for commercial buildings in cold and stormy climates,it is not only waterproof but is also able to protect against damage due to the wind as well as ozone and UV radiation.
- Longevity. Its rubber quality makes EPDM roofing one of the most durable choices for commercial structures, regardless of its style. Properly installed and maintained, it can last up to 50 years or longer.
- Eco-friendliness. Originally developed as an alternative to traditional petroleum-based roofing systems, EPDM typically utilizes recycled products. This means the material can also be recycled at the end of its service life as another roofing product or accessory, such as roofing and walkway tiles. In addition, EPDM roofs can be made reflective with coatings, allowing it to keep passive heating at bay and normalize indoor temperatures. This stabilizes energy use, which helps you cut back on your utility bill while helping reduce strain on the grid.
Did You Know?
EPDM accounts for more than 1 billion square feet of new roofing annually in the United States alone, representing approximately 35% of the entire roofing market. The market share is 12% (and growing) in Europe, with market shares in the Middle East and China notably accelerating as well.
TPO is another popular roofing material used for commercial buildings today. In Part 3, we’ll be discussing the reasons why you should strongly consider this commercial roofing option. Stay tuned!
