Pros and Cons of EPDM Roofing

EPDM(ethylene propylene diene monomer) also referred to as ‘rubber roof’ is known for its highly durable synthetic rubber membrane. It’s functional in both commercial and residential applications, from flat roof to patio roofs. You can find EPDM in black or white, and it’s available in a range of widths from 7.5′ to 50′, and thickness from 45 mil(1.1mm) to 90 mil (2.3mm). EPDM, like any other roofing system, has its share of advantages and disadvantages. Let’s take a quick look at some of the pros and cons of EPDM.


Pros of EPDM

Least Expensive Commercial Roofing to Install 

When compared to other commercial roofing systems like TPO, EPDM is the most affordable when it comes to installation.

Not Costly to Repair

EPDM rolls are long and wide, having fewer seams to fail, in comparison to other roofing types, like asphalt shingles or metal sheets. With the potential for fewer leaks, especially since EPDM ranges in thickness, or if it’s ballasted, repair costs tend to be cheaper than other roofing options. 

EPDM is Longest Lasting

Compared to other roofing systems, EPDM can outlast TPO and PVC commercial roofing systems. Many homeowners have enjoyed as much as 30 years and some, even more, from their EPDM. If your EPDM is professionally and properly installed, designed, and constructed it will last you a long time before it fails.

Hail & Ozone Resistant

EPDM is rubber roofing, which makes it resistant to impact by hail. It can even withstand large hailstones if your choice of EPDM is thicker than 75 or 90 mil and feature a ballasted layer. With an ozone-resistant rating of ‘A’ or 100º F, EPDM can keep the harmful effects of the sun at bay.

Other pros of EPDM include: 

  • Energy reduction, 
  • Fire resistant
  • High wind resistant

Cons of EPDM

Not Ideal For DIY Installation

It’s not that it’s impossible to do a DIY EPDM installation job, but it’s not encouraged. You have to know about the roofing system and what’s appropriate. For instance, it’s unwise to install EPDM roofing atop asphalt shingles will cause it to fail. Leave it up to a qualified EDPM professional installer should install an EPDM roof.

Can Be Punctured

EPDM can be punctured, but with a range of membrane thickness, it is possible to choose a membrane that is less likely to puncture. Choose a thicker membrane, like a 75 mil, with ballast for added protection from punctures. 

Unappealing Appearance

EPDM membrane is not the most visually appealing roofing on its own. What’s interesting about a large sheet of white or black rubber roof? Not much. However, with ballast, like rocks, EPDM can gain a little character.
