The 9 Best RV Roof Coatings
This wiki has been updated 25 times since it was first published in October of 2018. Chances are your RV spends all of its time outside, subjecting it to the often-brutal elements. You’ll need a quality roof coating to stave off leaks, drafts, and uncomfortable temperatures due to energy loss. These sealants come in liquid form and, once applied, they dry into a sturdy, solid surface. Be sure to pick the right option to keep the roof functional and protected from damage.

Editor's Notes
March 08, 2021:
Generally speaking, there are two types of RV roof sealants: Acrylic and silicone-based. They both perform well, although silicone is more resilient toward UV rays and water, and can maintain integrity even if water pools up on top of it. On the other hand, acrylic coating is compatible with more sealant types, more flexible, easier to apply, and often less expensive.
Overall, Dicor Signature Extended Life is one of the top silicone options out there, which is why it's earned the top spot. The difference between it and Dicor CoolCoat comes down to what level of insulation you need, and how much effort you're willing to go through to apply it. Both of these are widely considered to be the top of the class.
Alternatively, KST Kool Seal also offers positive insulation benefits, and Heng’s Industries TG-976 is about as easy to use as can be. Finally, if you need to be extra certain that your older motor home can fight leaks for years to come, you might consider Flex Seal Liquid Rubber in a Can. It's not purposely designed for RV roofs, but it works great and is about as durable a coating as you'll find.
