Disadvantages of EPDM RV roofs

While EPDM (Ethylene Propylene Diene Monomer) is a very popular material for RV roofs, it does come with its disadvantages. One of the biggest disadvantages of EPDM is its susceptibility to punctures and tears. This can be due to a number of factors such as sharp branches, hailstones, or even walking on the roof with hard-soled shoes. If left unattended, these punctures and tears can lead to leaks, which can cause significant damage to the internal structure of the RV.

Another disadvantage of EPDM is its poor resistance to UV rays. Over time, the sun's rays can cause the rubber to break down and crack, which will again lead to leaks. While there are coatings and sealants that can be applied to help protect the rubber from UV damage, this is an additional cost and maintenance step that needs to be taken.

Finally, EPDM roofs have been known to retain heat, which can make the interior of the RV uncomfortably warm during hot summer days. This can put additional strain on the air conditioning system, leading to increased energy costs.

Despite these disadvantages, EPDM is still a popular choice for RV roofs due to its affordability and ease of installation. However, it's important to be aware of these disadvantages and take steps to maintain and protect the roof to ensure its longevity.

Disadvantages of TPO RV roofs

While TPO roofs have many advantages, they also come with their own set of disadvantages. One of the main disadvantages of TPO RV roofs is their susceptibility to puncture and tearing. This is because TPO roofs are typically thinner than EPDM roofs and may not hold up as well against sharp objects like tree branches, hail, or debris on the road. It is important to take extra care when walking on a TPO roof to avoid causing unnecessary damage.

Another disadvantage of TPO roofs is their tendency to absorb heat, which can lead to increased energy costs for the RV owner. The white surface of TPO roofs reflects sunlight and helps to keep the RV cooler, but over time, the material can become discolored and lose its reflectivity, resulting in a hotter RV interior. Additionally, TPO roofs may be more prone to cracking and fading over time due to exposure to UV rays.

Finally, TPO roofs may be more difficult to repair than EPDM roofs. While EPDM roofs can be patched with a simple adhesive, repairing TPO roofs often requires heat welding, which can be more expensive and time-consuming. If a TPO roof is damaged, it is important to have it repaired by a professional to ensure the integrity of the roof is not compromised.

Overall, TPO roofs are a great option for RV owners looking for a durable, energy-efficient, and low-maintenance roofing material. However, it is important to weigh the advantages and disadvantages carefully to determine if TPO is the right choice for your RV.
