EPDM (Ethylene Propylene Diene Terpolymer) is a rubber roofing material that has been commonly used in the low-slope roofing industry for over 40 years. It has proven itself time and time again to hold up in the harshest of climates. Which is why it is one of the most common types of low-slope roofing options available.
Architects, roofing professionals, and builders of new construction can all attest to the high quality of this product. But don’t take their word on it. The true test of a high-quality building material is its longevity. EPDM has proven itself to be the leader in low-slope roofing options with most applications lasting an average of 40 years.
Why is this product so effective at sealing out the elements of a low-slope roof? Let’s have a look at some of its components first:
- Excellent resistance to heat from sunshine and fire
- Extreme resistance to hail damage
- Proven durability against thermal shock
- It maintains flexibility even in the coldest of climates
- Fatigue resistant membrane
- Strong ultraviolet resistance
EPDM is also a proven leader in wind resistance, making it the top choice for windy locations. This roofing system has several options the installer can use to protect against wind uplift, including a rating from 0-120 MPH! Truly, an unprecedented achievement in roofing technology.
What is EPDM?
EPDM is a man-made form of synthetic rubber, which has high elasticity characteristics. As well as low-sloped commercial roofing systems, it is also made into gaskets, electrical insulation, and lamination’s.
It comes in large sheets, which range from 10 feet – 50 feet wide, and up to 200 feet long. Thickness varies from 45 – 90 mils.
Installation is done by adhering the rubber membrane to the substrate material by use of a bonding agent. This bonding agent is applied either manually or with mechanical devices, which ease installation and speed up the process. When the width of the roof is greater than the membrane roll, the edges are butted together and joined with a seaming tape which allows the membrane to maintain its waterproof qualities.
When repairs are required. EPDM is the most easily repaired roofing system on the market. The roofing material is not affected by age so repairs can be done easily and quickly without affecting the long-term durability.
Unlike other roofing materials that often times degrade over time, EPDM single-ply membrane maintains elasticity. To make the repairs, oftentimes the contractor will simply wash the area that needs repair, prepare the area for the repair, apply the adhesive and install the new membrane over the top of the damaged area.
If you are looking for long-term durability at a low cost for your commercial flat roof, then ask your local contractor if EPDM roofing is the right choice for your application. It comes with an excellent guarantee and will surely outlast any other type of roofing material.
