All You Need to Know About EPDM Roofing Systems

EPDM roof is one of the house roofing system

When it comes to flat commercial roofing systems, there have been some major improvements made to the materials used in these roofing projects. One particular roofing material which is emerging as the best option for flat commercial roofs is known as EPDM, or Ethylene Propylene Diene Terpolymer. As far as most commercial property owners in the Vancouver area are concerned, an EPDM roofing system will be able to stand up to virtually anything nature has to throw at it for a number of years. To help you familiarize yourself with this roofing material, and to determine how well suited EPDM is for you commercial roofing needs, take a look at the helpful information listed below.

What is an EPDM Roof?

            This type of roofing material is made from a combination of rubber materials which are compressed into a single ply membrane that covers an entire flat roof. Originally introduced in the 1960s, constant improvements made to the EPDM formula and installation method has helped keep this material as one of the top choices for commercial flat roofing projects.

EPDM Roofing Benefits and Downsides

            While no roofing material will ever be perfect, EPDM has come a long way since its first uses in the mid 1960s. The durable single ply membrane is capable of resisting virtually all precipitation without shrinking or cracking in the sun for at least a couple of decades. In addition, the bright colour of EPDM allows it to remain effective at reflecting sunlight from a roof surface, which helps improve the efficiency of a commercial building. There is virtually no weather event that can reduce the resistance or lifespan of an EPDM roof membrane.

            Unfortunately, due to the single ply thickness, solid objects like falling branches can cause damage to an EPDM roof, and repairs and patches must be completed by professionals using appropriate materials. Building owners should also be aware of the fact that EPDM roofs require an experienced team for installation, as mistakes or poor installation can lead to cracks in the membrane seams, leading to leaks and extensive interior damage. One other consideration is the fact that EPDM can deteriorate from exposure to things like oil and grease, so commercial building owners with grease traps on their roofs should be aware before making EPDM their roof material choice.

Types of EPDM Roofing

            For the most part, the formula for all EPDM roof membranes is the same, and each type will come in a bright reflective colour for added UV protection. You can select EPDM roofing based on thickness. It is available in 45mm, 60mm and 90mm thickness. You can also choose between reinforced and non-reinforced membranes for additional protection.

Roofing Durability and Cost of EPDM

            Thanks to its flexibility and toughness, EPDM stands as one of the most durable flat roofing materials available today. In terms of its lifespan, a properly installed and well maintained EPDM roof is capable of lasting for up to 50 years! Due to this longevity, you might suspect that EPDM is also very expensive, but it is actually quite affordable compared to other flat roofing materials. Depending on the size of your roof and the quality of the EPDM you select, you can expect to pay between $4 and $6 per square foot.

Where is EPDM Usually Installed?

            Given that we are discussing this as a commercial flat roofing material, it should come as no shock that EPDM is usually meant for commercial flat roof covering. While this is probably the most effective method for using this roofing material, due to the flexibility and resistance to shrinking, EPDM can be used on irregular roofing projects as well. Keep in mind that the bright colour of EPDM really stands out, so it is usually best suited for roofs which are not entirely visible.

Who Can Install an EPDM Roofing System?

            As we mentioned above, the installation process of an EPDM roof requires a particular set of skills to ensure the roof lasts its entire lifespan. While it is possible for some people to take a DIY approach to patching and cleaning an EPDM roof, the initial installation of this membrane is best left up to an experienced team of professionals. Not only will this provide you with peace of mind knowing your roof is in good hands, you will also be able to qualify for extended warranties if you work with a certified roofing company.
