Roofing requires so many materials to use. And EPDM is the most common among them. But you may wonder, what is EPDM Roofing? 

Well, EPDM is a synthesized rubber roof material that lasts a long time. For more than 40 years, it has been utilized on low-slope roofs.  

Feel more to know to be convinced? We are here to meet your thrust. 

Let’s take a closer look at the whole content and have the desired answer.

What Is EPDM Roofing?

EPDM is an acronym for ethylene propylene diene terpolymer. It is mostly made up of propylene as well as ethylene, these two are sourced from oil, natural gas respectively.

EPDM roofing was first introduced in 1970. Over the last 40 years, it has a fantastic track record in commercial uses. It is commonly utilized for its excellent water resistance and durability. This roofing is also cost-effective. Now we’ll tell you about some of the remarkable features for which it is well-known.

EPDM comes in 2 colors. The one is black, while other one is white. It’s also available in various sizes. Its width ranges from 7.5 of between 50 feet and a thickness of 45 and 60 mils. A completely attached, mechanically connected, or ballasted system can be used to implement EPDM. Continue reading if you want to learn more about it.

Some Important Aspects Of EPDM 

High ultraviolet light resistance

EPDM is extremely resistant towards ultraviolet light, which is why it never fades and keeps the business floor area cooler than it would be otherwise. As a result, it is an acceptable option for a wide range of commercial needs.

Resistance to fatigue

EPDM has a high level of fatigue resistance, which is a measurement of a bearing’s strength, particularly in the case of combustion engines, where the loading is periodic in both direction and intensity. This incredible characteristic allows it to fit in with any type of construction.

Resistance to water

EPDM has been proven to be extremely resistant to hail damage as well as ozone-induced corrosion. Furthermore, with the significant temperature swings that so many areas of the globe are facing, EPDM roofing provides a solution to roof damage caused by excessive temperature swings.

Since the consequences of global climate change are becoming more widespread every day, any business must have a weather-resistant roofing system. EPDM roofing is thus among the most advantageous options available for a company.

Resistance to fire

Having an EPDM rooftop over any business building may be considered as a major milestone in the fight against major fire-related disasters. Because the EPDM roof is very resistant to fire hazard. It guarantees that you are safe underneath the EPDM roof implementation.


Because of its remarkable durability, EPDM is often regarded as the best choice for low-slope commercial roofing. It has the ability to provide long-term performance as well.

EPDM may be applied in three ways:

Ballasted System

This is the most common EPDM roofing system, responsible for about 35% of all EPDM roof constructions currently. Ballasted systems are mostly utilized during new major infrastructure works. However, they may also be employed for roof repair as well as recovery installations if the current system can handle the extra weight.

This method, which employs large panels of roughly fifty by two hundred feet, enables quick coverage at such a cheap price. Ballasted techniques are by far the easiest to set up of any system.

Mechanically Connected System

Mechanically connected systems are small and light, making them suitable for a wide range of building measurements and designs.

Mechanically connected systems may be implemented in two ways: big panels can be attached through its membrane, and small panels can be attached mostly in the sides lap.

Based on the needs of the landlord, scrim reinforced and non-reinforced coverings can also be employed. Then the covering is connected with its bottom deck with either circular plates or batten strips.

Completely Attached System

Due to technical improvements, the fully attached system has become the standard option for professional roofing projects in many parts of the state. This method makes use of panels that are roughly thirty by one hundred feet in size.

The membrane is physically adhered to the insulation through mechanical screws, adhesives, and stress plates. Coverings that are both scrim reinforced and non-reinforced can be used.


I hope you have found this information useful. And you are now aware about What Is EPDM Roofing?

The rubber based EPDM roof already has remained a popular choice for low-slope roof construction for nearly 40 years.

Roof consultants, builders, and architects choose the highest roofing choice for both new housing and restoration roof installations, as per market research from Building Design and Construction, roofing/insulation/sliding magazines, also the National Roofing Contractors Association.

So, it was our utmost effort to give you the answer. Have a good day.


As a civil engineer and roofer, I love to share the experience that I have gained through the last couple of years. In the roofing industry, practical experience is a very crucial fact that can help you a lot. Hence, I want to help you with my blog.
