EPDM Roofing


If you are looking for a new roofing choice for your stand-alone commercial structure, then look no further than the quality and efficiency of an EPDM Roof. For more than 60 years, EPDM roofing installations have been considered the best choice for their versatility and flexibility, and that applies to flat roofs as well as semi-sloped.

But why does EPDM shine in comparison to other traditional commercial roof options? The answer to that is simple. It’s the material. Read on and learn what makes EPDM roofing an amazing choice for commercial roofing applications.

What is EPDM?

EPDM, or Ethelene Polypropylene Diene Monomer, is at its most basic core a membrane, single ply, made of mostly ethylene and propylene, and is so resilient, the typical life expectancy once properly installed can be 50 years or better. It does require some maintenance to last to its fullest life expectancy, but the upkeep is a small price to pay for such a lasting, high-quality roofing material.

Because of the materials, it is also called a “rubber roof.” When fully adhered, it is more flexible than any other roofing option, is the easiest material to install on commercial flat and low-slope roofs, and with its 4 distinct layers, is completely waterproof. And the materials will not degrade, so if it does get wet, the runoff will not result in pollution

The four layers of EPDM roofing are:

  • The Elastomeric Base Layer
  • The Fire-Retardant Middle Layer
  • The Polyester Reinforced Top Layer
  • And if you wish, an Optional White Top Layer can also be applied.

The Base layer is predominately rubber and is heat resistant, keeping your energy bills down inside the commercial structure. The middle and top layers are specifically for fire resistance. If you do opt for the white top layer, the main purpose is to reflect the sunlight, adding an additional cooling feature, much like the reflective visor in your windshield when you are not in your car.

Installation of EPDM

Your commercial roof takes a beating. The elements alone are enough to dry, degrade, and destroy even a quality commercial roof over time. The EPDM is designed to combat these attacks from nature and be a resilient force for steadfast longevity. Even high wind and hail are no match for EPDM. And that applies regardless of thickness and color choice as long as they are properly installed.

Installation is done in a few different ways. The most common begins with an approved floor deck, corrugated to allow air below the layers for heat evacuation. Then an insulation is added, followed by the 4-layer EPDM, and for aesthetics and extra security, stone or paver is poured on top. The gravel often seen on commercial roofs is this final layer.

The EPDM comes in sheets of three thicknesses, none more than 90 millimeters. The thicker the EPDM, the more resistant it is to damage. When having yours installed, where your building resides is going to be a factor. If you have constant windstorms, hailstorms, or torrential rain, a thicker EPDM will last you through most elemental barrages. If you have a low percentage of being hit by violent weather, something as thin as a 45-millimeter EPDM will work perfectly and save you money.

What Are the Benefits of EPDM?

We have touched on the versatility of the materials and how they function in cooling and protecting your structure. But the perks don’t stop there.

  • Cost-Effectiveness

In real estate and business, the bottom line is important. Compared to other roof installations and repairs, EPDM is second to none. It is quick and easy to apply, and if it gets damaged by puncturing or you notice leaks, the fix is as simple as putting on seam tape or replacing only the damaged section. Many commercial roofs require entire areas to be redone when under the same circumstances.

  • Quick and Easy Install

EPDM comes in lightweight rolls that cover large areas in almost no time. Speed of installation cuts down on your installer’s hourly estimate and overall material costs.

  • Energy Efficiency

Commercial structures are a monster to keep cool in the hot months. EPDM’s layered design helps to cool your space by absorbing and releasing solar radiation. During cold months, it insulates and retards hot air from escaping. The color of the membrane you choose will make the biggest difference. In hot climates, a white membrane reflects heat while in cold climates a black membrane will collect the sun’s warmth into your structure.

  • Quality Material

Durable, resilient, versatile, flexible. Need we say more? Yes, well how about its ability to naturally expand and retract in changing temperatures without cracking or splitting? With a thick EPDM roof, a ballast layer, and an external fleece reinforcement, you will not only be practically impervious to hail, snow, hard rain, high wind, and even punctures. EPDM is 300 times more resilient than other roofing materials where element-related damage is concerned.

Choose Cool Roofs For Your Next EPDM Installation Or Repair

If you are ready to have EPDM installed on your commercial structure, you have made a terrific decision. You will notice lower heating and cooling costs, lower maintenance bills for roof upkeep, and if you lease the space, your tenants will appreciate how EPDM affects their own bottom line. With only minimal upkeep, your investment will show dividends over the next 12-25 years depending on the thickness of the EPDM you choose. Can you say that about anything else in your commercial structure?
