  • Can be used for living roofs and ponds
  • Waterbased

If you are planning on using these to coat a living roof or pond, they should work just fine. A main concern when using a liquid roof coating is seeing how well it will hold up over time. Because these are water-based, the worry of peeling away, or the coating losing its shine with time is significantly reduced.

This is one of the easiest to use coatings that I tested. Though I didn’t test a whole lot, I was impressed with how easy it was to put the kit together. Simply apply a thin even coating, allow to dry, and lightly scuff it to give it a sandpaper-like texture.

I like that some of the coatings, like this one form a bond between the shingles and the metal. This will make future repairs much easier if ever needed.

Frequently Asked Questions (FAQ)

What is the best RV roof coating?

It depends on your priorities. There are four main factors you should consider:

  • _ Durability – how long will it last?
  • _ Fire Protection – how long will it take to burn through?
  • _ Cost – is it worth the price?
  • _ Sustainability – is it "green" and environmentally friendly?
  • How long does RV roofing last?

Most RV roofing material has a life expectancy of about 20-25 years, with the majority lasting closer to 20 than 25. This means 20-25 years of water repellent protection. That’s about 82-100 weekly cycles, and it can vary depending on the manufacturer.

What type of roofing material should I get?

There are two main types of roofing material for RVs, though there are exceptions to both:

What is the best rubber roof sealer?

Since sealing your roof will likely prolong its life, then you should choose a quality roof sealer that will last the longest. Silicone based rubber roof sealants have been around a while and have stood the test of time. They are ideally suited for areas with high UV exposure and weathering conditions like you might experience in your RV. These roofing sealants also have longer lifespans than acrylic sealants.

For simple, budget-friendly choices, acrylic roof sealants are a good choice. They are much easier to work with than silicone when applying and in most cases they do a quality job of sealing.

For those seeking the best rubber roof sealer in the long-term, opt for silicone based sealants…which will probably end up being more cost effective too!

Can You Use Flex Seal on RV roofs?


We found this product in a bunch of places, claiming that it is suited for RV roofs. They everywhere say that it can easily fix RV roof leaks. We were impressed by the number of positive reviews given to Flex Seal. We decided to conduct a little research of our own.

The short answer is that it can work to fix leaks, but ONLY if they are caused by a puncture in the roof. If the leak was caused by an RV missing piece of shingles, then Flex Seal will only hold that piece up until a piece is cut and installed properly.

We honestly cannot see Flex Seal being as good as a custom cut roofing piece. For the first option, you'll have basically a 1/4 inch insulation between the new replacement shingles and the existing surface beneath, which might not be a great idea.

What is the best coating for a flat roof?

The best coating for a flat roof is a long-lasting one. The lifespan of a flat roof depends on where you live. Colder areas mean more frozen ice and snow, which means more wear and tear on the roof. In the hotter areas, there could be more sun and sun damage. You’ll need to consider the amount of use your roof will receive and the weather conditions your roof has to endure.

You will need to know the exact pitch of your roof and then select either a snow-rated or sun-rated roof based on that rating. This will determine how flat or sloped it is, which largely determines how much it will wear down over time.


The world has a large number of RV roofs; some are shiny and some are dull. Does your RV roof look dull? Well you obviously need to fix that. We’re going to take you from various types of RV roof coatings to a buyer’s guide that will guide you during the process of buying the best RV coating for your roof. We’ll also review 10 roof coatings that have been rated highly after extensive testing.
