EPDM is a synthetic rubber that is extremely durable and flexible making it perfect for RV roofs. It’s even resistant to UV so where other rubbers will split and crack EPDM will last for years in the sun on the roof of your RV.

This article will answer what is an EPDM RV roof, and go into more detail about what EPDM is and why it’s so good to use it as a roof cover on your RV.

What is EPDM?

EPDM stands for ethylene propylene diene monomer, which is a type of rubber. It became popular because of its durability and resistance to UV radiation. Because of this it is used in many different industries.

EPDM is a rubber waterproofing membrane that is commonly used in the construction of swimming pools, parking garages, and driveways. Epdm can be installed on flat roofs, sloping roofs, RV roofs and vertical walls. It is an alternative to liquid-applied roofing membranes because it can withstand higher temperatures and provides a longer warranty. It also contains a UV-radiant barrier that protects it from solar radiation.

EPDM was discovered by German scientist Karl Ziegler who later won a Nobel Prize for Chemistry for his work on controlled polymerisation. [1

Why is EPDM Used on RV Roofs?

EPDM is used on RV roofs because of the number of benefits it offers over conventional rubber. EPDM has a life expectancy of 20-30 years and decreased maintenance. 

It’s also resistant to tears and punctures, which means it can withstand hail storms and high winds. EPDM is also resistant to mention debris and bird droppings which makes it perfect for the daily life on the road that comes with an RV.

The problem with a standard rubber roof is that it is a natural material that will eventually deteriorate and crack. This means that it is going to need constant upkeep, which can be hard for those living in a RV. The rubber material will also ooze and drip when the heat is too high or if it freezes, which can be very unsafe for those below. EDPM is resistant to UV and temperature changes therefore making it hardier and less likely to split and crack over time.

Furthermore, EPDM may have an environmental advantage over other roofing materials, because it doesn’t contain any petroleum byproducts or volatile organic compounds that may harm wildlife habitats.

All of these properties make EPDM ideal for roofing and even better for RV roofs as they are prone to even more changes in the environment than static buildings.

How is EPDM Applied to an RV Roof?

Installing EPDM to an RV roof is a simple process, you simply glue it on. Make sure that the rubber side is applied face down directly onto the roof and the UV protected side (usually white) is facing upwards.

Apply the glue to the roof and roll out the EPDM whilst it’s still wet, smooth out any air bubbles with a brush and then trim the edges. This Youtube video will show you how to do it:

 

How do I know if my RV roof is EPDM?

To figure out if your RV roof is made from EDPM already you can either check the warranty or user manual if your RV is new and not had any work done to the roof then it should tell you.

If your RV is older then the best way to tell if your RV roof is EPDM is to look at both sides. If one side is white and the other a black rubber then it’s EPDM. if it’s the same color on the top and bottom then it’s likely that your roof is made with TPO.

Advantages Of EPDM For RVs

The benefits of using EPDM roofing for RVs are many. With high resistance to UV rays and chemicals, this type of roofing is ideal for the frequent trips and often-humid environments that an RV will experience. The rubber material is also highly flexible, making it a perfect choice for such a mobile structure. 

Here are some of the advantages to using EPDM on the roof of your RV:

  • Longer life expectancy
  • Flexible
  • Resistant to tears and punctures
  • Resistant to UV 
  • Resistant to temperature changes 
  • Environmentally friendly

Disadvantages Of EPDM For RVs 

The only real disadvantage to EPDM for your RV roof is the price. This is mainly due to EPDM coming in black as a standard color, which is not the color you will want on your RV roof so it costs and extra 30 to 40% more for the white EPDM.

Final Thoughts

If you’re looking for a material that will provide the best solution for the roof of your RV then EPDM is your best bet. Unlike other materials that can cause leaks over time, EPDM is designed to be puncture resistant and watertight. This means it won’t leak or fail to keep out water.
