  • Start by washing off all the dust, dirt and debris using a pressure power washer 2,000 PSI or under.
  • Get a bucket full of a gallon of cold water.
  • Mix 6 to 10 ounces of a mild non abrasive detergent or cleaning solution with the water to create a TPO safe cleaning solution.
  • Choose a push broom with soft bristles and start sweeping from one side of the roof.
  • Make sure to sweep all the dirt in one direction towards the drain for easy clean up.
  • Once sweeping the entire roof, use the pressure washer and wash off the accumulated dirt from the roof.
  • Repeat this same cleaning process as many times as necessary until all the dirt is completely cleared away.
  • Rinse away all the cleaner from the roof using the water hose.

3. Installing A Good Drainage System

Since the RV roof is completely flat, it needs a proper drainage system to function. Otherwise, rainwater or snow will gather around on the roof without any actual drainway to go into. As a result, the roof will get pools of water which will damage it.

Install a proper drainage system with gutters and downspouts that lead outside. Check it periodically to make sure that no debris or dirt is blocking the drainway.

These materials can withstand hail, snow, rain, high temperature and protect the roof from all these rough environments. You can also choose fluid coatings in order to avoid the problem of pooling water.
