Everyone knows that when water freezes, it expands, which can lead to disastrous results in an RV. If that water gets in some problematic areas, it can cause the roof to leak. There's really nothing worse than opening your camper in the spring, anticipating a traveling adventure, only to find a different kind of adventure that includes cleaning, mold removal and fixing water damaged parts. 
The best way to avoid this scenario is to store your RV indoors during freezing weather. If you don't have a large building, you can usually rent indoor storage in the winter, which has the additional benefit of freeing up space in your driveway or yard too.
If you don't have an indoor storage option, then you need to decide whether you should cover your RV. Covering will protect your RV from water, pine needles, leaves and other debris, but it's important to choose the right cover. Purchasing a large tarp from the home improvement store seems like a good, cost-effective solution, but many people find an unwelcome surprise when they remove it in the spring. These tarps don't allow air flow, so any moisture that gets under the tarp, even just from condensation, will turn to mildew and mold, which is a hassle to remove.
A special RV cover is the best option to take care of your RV that is stored outside in the winter. Choose a quality product that will allow air flow and claims to be tear-proof. It will protect the camper without trapping moisture underneath. Make sure the RV is clean and dry before putting it on, and use extreme caution if you need to get up on the roof to install the cover.
Water damage can be very costly to an RV, and in some cases the damage can be irreparable. In addition to taking care of winterization of the water lines and tanks, make sure you protect the roof of your camper by storing it indoors or using a specialized RV cover.
