9 Best RV Roof Coatings (for Fiberglass, Aluminum, Rubber etc.)

You did it! You finally have that RV you have always wanted! Your mind is in constant motion, thinking of all the great places you will visit.

Another thing to consider is what you might need to do to ensure that RV will be ready to travel in any kind of weather. You could pass through torrential thunderstorms, brutal sunlight, perhaps even snow and ice. But the weather isn’t the only possible issue. You could incur damage from a falling tree limb or other low-hanging obstacles that could poke a hole in your RV roof.

Taking preventative measures, such as a good roof coating, will protect the RV from wear, leaks, and other issues that could lead to more costly repair and maintenance.

Buying Guide

The cost of RV roof coating can vary quite a bit. Home Advisor reports that the average cost to seal a roof is $971 and typically ranges between $382 and $1,568. However, you may pay as little as $100 or as much as $3,200 or more. The type of roof, type of sealant used, the condition of your current roof, and your location all affect the price. When purchasing an RV roof coating, there are several things to consider. A few of them are:

  • The function of a good RV roof coating.
  • What are potential additional uses for RV roof coatings, such as other roofing or waterproofing needs around your house?
  • There are coatings for each type of RV – in particular, coatings for metal and rubber RV roofing are very different, so ensure you are purchasing the correct type of coating.
  • Benefits of a good roof coating – it provides waterproofing, reflects heat, extends life, and it resists flames and corrosion.

Solvent-based silicone coatings are viewed most favorably. They can be applied to a roofing system using many different techniques, including spraying or rolling. Silicone coatings are available in many colors, including reflective white and translucent.
