Many RV owners have issues with mold on the roof. Here you will learn how to DIY RV roof repair and clean existing mold away and how to help prevent it from forming in the future.
Steps for Cleaning:
It is important to keep your safety in mind whenever you are working on the roof of your RV. You could be seriously injured if you slipped and fell off the side. Always wear rubber-soled shoes that provide maximum traction when you are working. Be aware of anything that could cause you to trip.
The first steps are to sweep away any loose debris and then wash the roof as you normally would. There are cleansers made specifically for cleaning RVs. Once everything but the mold is rinsed away, climb back down and mix up your mold remover.
You will need one cup of household bleach mixed with one gallon of water. Fill a large spray bottle with the mixture and climb back up on the roof. Spray any areas where you see mold, mildew or other stains. Allow the solution to set for 15 minutes.
After the solution has dried, take a soft scrub brush and wet it with the same bleach solution. Scrub away at the stains. It may be necessary to spray the areas again if they are resistant to your scrubbing, and allow the solution to set again. Once you have removed all of the mold, rinse the area completely with clear water.
Mold grows in moist, dark and warm environments. Keeping your roof dry is the best way to prevent mold from growing. This typically means covering the vehicle whenever it is in storage.
Some covers are not resistant to wind. During a windy rainstorm, water can get up under the cover and settle on the roof. The sun comes out and dries up the water but also gives mold spores what they need to grow. Ideally, we would all have garages large enough to park our RVs indoors, but many of us do not.
Another solution is a water and weather resistant coating. There are a variety of these coatings like Liquid EPDM Coatings, Liquid Roof, Liquid Rubber Coatings, on the market. If you are the do-it-yourself type, you can apply the coating on a sunny weekend.
While the coatings may seem expensive at first glance, once you think about how difficult it was to remove the mold and mildew, you will see the advantage. RV stores sell the RV leaks repair coatings but you may get a better price at if you order online with http://www.epdmcoatings.com/.
