By cleaning the roof of your RV at least once a year, you ensure that the material will last much longer and keep your unit free of leaks and damage. Taking care of an RV roof is a simple process, but it can be fairly time consuming and dangerous if you don’t take the proper precaution. With the right methods and materials, you can keep your roof in tiptop shape and not have to worry about it until its next cleaning. In this lesson, we teach you how to clean a TPO roof with basic commercial products and an hour of your spare time.

How to clean a TPO roof: a step-by-step guide

When it comes to most makes and models, the warranty on your RV should last 10 years, assuming you take proper care of the vehicle. That goes for every component on the unit, including the roof. If you clean and condition the roof regularly, it should be under warranty should you experience any unforeseen issues. With that in mind, you should only need to clean your roof once a year to keep it in good shape. To help you figure out the correct way to maintain your rubber roof, Dave Solberg walks you through a step-by-step demonstration on how to clean a TPO roof.

In beginning to show you how to clean a TPO roof, Dave introduces some things you should be aware of when you’re up on the rubber roof, including walking on wet spots near the corners of the roof. He explains which products he prefers to use, such as a rubber roof cleaner and conditioner you can pick up at a local store, and then teaches you how to clean a TPO roof with simple scrubbing motions.

You’ll learn some easy tips for maintaining the areas around vents and antennae, as well as how to safely clean a TPO roof to avoid damage to the rubber. He also recommends keeping a close eye on cracks and indentations that might eventually lead to punctures and, in turn, leaks. With this quick walkthrough on how to clean a TPO roof, you’ll be able to thoroughly wash and condition your rubber roof to make it last much, much longer!

      Hi, Mike. For this demonstration video we used a rubber membrane cleaner from Camco purchased at our local Walmart store! This works well, but it depends on the type of material you are cleaning! EPDM and TPO can be cleaned with either the Camco product or even Dicor, however Dawn Dish Soap is now being recommended by the fiberglass and Alpha membrane manufacturers. We used it on a fiberglass roof in one of our exterior care and maintenance classes and it worked great!

    If there is no ladder to get on the top of the roof, is it ok to get up on the roof? I have a 2017 Keystone Cougar X-Lite 33RES?

      Hello Timothy,

      Yes, some manufacturers do not put a ladder due to the fiberglass cap on the back or a picture window! Just be careful to not step to close to roof vents, the air conditioner, and other items that have been cut into the roof as there might not be much structure around them to hold the weight. I would stay at least 2’ from these items. If you don’t have the 2’ area, place a long 2×6” board on the area you want to walk which will transfer the weight across the roof.

    Could you tell me what brand long handle brush you used and where purchased.

      Hello Jerry,

      I bought this mop at Menards which is a midwest home improvement store similar to Home Depot and do not remember the brand. However I see HD has several “Quickee” brand models that are very similar. It’s a simple mop with a soft sponge on one side and a scrubber material like scotchbrite on the other side. You can also use a broom with a very soft bristle head also available at most home improvement stores. Typically these are wider and you would need a wider bucket and they do not hold the soap solution as well as a sponge type head.

      Hello Jerome,

      I use one gallon of water for one jug of cleaner. Another option is to use Dawn Dish Soap (blue) and put in about 3 oz for every gallon of water.
