A Close Look at a Roll of EPDM Roofing

Rubberised Membranes & Affordable Roofing

Flat systems take on a variety of unique challenges in the roofing world. From trapped debris to ponding water, there are plenty of hazards that threaten to cause a premature end for your flat roof. Thankfully, there are cost-effective and trusted solutions to protect your building from the elements.

Today, we’ll discuss one of the most popular and widely sought after flat solutions on the commercial market: EPDM roofing. We’ll chart the various pros and cons of the solution so that you can determine whether or not it may fit your business’ needs. Let’s dive in!

Is EPDM Roofing Any Good?

That’s the real question that businesses need answered. EPDM roofing provides very capable protection against a variety of weather-related problems. We’ll break down the capabilities of this single ply solution below.

Key EPDM Roofing Benefits

Most commercial businesses favor EPDM for its very affordable pricing. Both material costs and the price of installation typically fall below other single ply materials. Because of its rubber base, EPDM also offers wonderful flexibility against the daily expansion and contraction caused by solar heat.

The two major downsides for EPDM roofing is the traditionally black surface and the occasional leak. Because dark colors tend to absorb more heat than reflective options, rubber roofs often admit more heat into the building.

While they have fewer seams than other forms of roofing, EPDM roofs utilize seam tape (which is vulnerable to leaks in the long-term). Leaks aren’t typically as dramatic as a water heater repair incident, but they are something to look out for after serious storms. Potential for leakage is influenced by the chosen membrane thickness. How thick is EPDM roofing? You’ll find most solutions fall under 45 mils or 60 mils thickness.
