Why should I use rubber roof coating?

RVs will typically stay outdoors throughout the year. An outdoor environment is not good for roofing, plastic walls, wood, and so on. When you keep your RV in an outdoor environment, your exterior will naturally start to lose its shine, especially in areas with dramatic climatic conditions such as cold winters or hot summers. This is especially true in climates with heavy amounts of precipitation. In these sorts of conditions, a rubber roof will prove to be a strong defense against nature’s forces.

How long does rubber roof coating last?

Although you might just paint your rubber roof coating on once, you will likely want to put a new coat on every 3-5 years to make sure that it maintains the same effects. Since putting on rubber coating is a relatively straight forward process you won’t be dreading the next time that you have to do it. In the end, it will only help your vehicle last longer.

What types of RV roof coating are there?

RV roof coating comes in two different formulas, EPDM and TPO.

EPDM, or Ethylene Propylene Diene Monomer typically requires less maintenance so a roof coated in this material will often remain protected for longer before needing further coats. EPDM is noted for its resilience to both water and UV exposure.

TPO, or Thermal Poly Olefin is contracted differently to EPDM.

Typically, TPO provides a shinier finish and provides a lot more rigidity than EPDM. It is also less prone to oxidization as it is contracted using less plastic.

How do you install rubber roof coating?

Putting rubber roof coating on your vehicle can be done within one day. To do this, first, decide which product is best for you. Then all you will need to do is use a roller and apply the coating like paint to the roof. It is best to do this process in temperate conditions that are neither hot nor cold so that it dries as evenly as it should. You can use this on any RV roof, and it will need to occasionally be redone.
