12 Best Coatings & Sealants for RV Roof in 2022

Once the coating cures, it can produce a sturdy coating for your RV’s roof, which can last for a maximum of 10 years. What’s good about the EPDM coating is that you can easily apply it. It is even possible for you to complete the whole process in just one weekend provided the weather is good for the curing process.
The EPDM liquid RV roof coating is also known for being weatherproof, puncture-resistant, energy-efficient, and flame-retardant, which means that there’s no need for you to worry too much about spreading fire in case some nearby campfires get out of hand.
To help you choose a rubber roof coating in this category, here are some of your ideal options:
1. Flex Seal Liquid Rubber in a Can
The Flex Seal Liquid Rubber in a Can is excellent for a camper roof coating. It offers RV owners like me a more reliable and effective way to protect their motorhome interiors against water damage while safeguarding their roofs against the elements.
I like this roof coating’s liquid rubber formulation. Rubber is elastic, allowing it to withstand environmental factors better than other coating substrates.
It also forms a waterproof barrier on my camper roof, protecting the occupants against a drizzle when it rains. This RV rubber roof sealant has exceptional weather resistance that RVers will appreciate.
Unlike other roof sealants, applying this motorhome roof coating is a cinch. I dipped an ordinary paint roller in the container and rolled the material onto the roof. They can also use a regular paint brush or spatula. Its liquid formulation also makes it ideal for pouring into open spaces.
The best part about this roof coating is its extensive material compatibility. Most people use it on metal, brick, wood, concrete, glass, and ceramic surfaces. However, I find this product also suitable for fiberglass and aluminum motorhome roofs.
I will never worry about nasty mold and mildew growth, rust, and corrosion because this product effectively covers RV surfaces.
This RV roof coating also dries faster than other brands. It would be wise to plan the application to allow adequate surface smoothening. Unfortunately, the coating emits an offensive odor lasting four to five days. It would be best to leave the motorhome during this time.
2. Dicor Acrylic Elastomeric Coating for Metal RV Roofing

Like many elastomers, this product creates a strong bond on the metal surface. This roof sealant for RV is elastic enough to move with periodic surface contraction and expansion. RV owners will feel more confident this product retains its weather protection for many years.

Several brands of roof coatings for RVs emerge in the market today, making it convenient for RV owners to make a selection. The wide range of options for this product makes it a glory to buy since you can really find one that suits your specific needs.

Does Flex Seal work on RV roofs?
The answer to this question is a big yes. Take note that Flex Seal is one of the most versatile roof coating or sealant available in the market today. With that, you have a hundred percent guarantee that it will work well on your RV roof. It is perfect when applied to gutters, campers, RVs, mobile home roofs, gutters, vent pipes, and skylights.
When used in an RV roof, you are assured of its ability to seek into holes and cracks. Once dried, you will also notice that it is a flexible, watertight, and rubberized coating designed to last for quite a long time. It seals out water while also staying pliable and flexible.
How Flex Seal works, however, will also depend on the type of material used in your RV roof. It works well on fiberglass and metals but not that great when used in EPDM rubber roofs.
How to apply an RV rubber roof coating?
A rubber coating is one of your best options if you are looking for a coating for your roof. Applying it is not also difficult. You just need to apply the rubber roofing product to enjoy its durability, flexibility, reliable protection, and UV stability for a long time. The first step in applying the coating is to measure the width and length of your RV roof.
Determine the roof’s actual surface area by multiplying the two measurements then dividing the result by 42. The result will give you a rough estimate of the number of gallons you will need for the whole RV rubber roof coating application process. Make sure to apply the coating in an area with proper ventilation.
Get rid of any source of ignition. Note that uncured product is considered as a flammable liquid. Also, ensure that the product needs to be in an area with room temperature to make it much easier to apply.
Prepare the roof’s surface afterward. You can do that by combining water and laundry detergent then using it to give your roof a power wash or scrub it. Your goal is to get rid of as many surface dirt as possible. Take out anything, which is made of silicone. It is because you can’t expect the coating to adhere to this material.
You should also remove poorly adhering roof coatings and loose caulking. Flush these things out using clean water. Let the area dry completely. Once it dries, you should get a brush and use it in applying a light coat of the rubber coating. Your goal here is to cover depressions, seams, and any other options that protrude to the roof.
These include pipes, skylights, and vents. Also, apply a light coating on areas that are quite difficult to access using a roller. In case of rounded edges in a roof membrane, ensure that you put on a light coating with the help of a brush. Apply this to the rounded edges as well as the vertical part.
Let the coating dry for around three hours. After that, you should put on more coat (but make sure that it is just thin) to the whole roof surface with the help of a nap roller. Once done, you should let it dry for approximately 48 hours. After 48 hours, get a long nap roller and use it to apply a finishing coat, if needed.
How often should you coat your RV roof?
How often RV owners must recoat their RV roof depends on a few factors. Still, the average is once every two to four years.
It is ideal for RV owners to inspect their motorhome roofs every six months as a crucial aspect of periodic maintenance. It enables people to identify tiny roof problems they can fix immediately before growing out of proportion, requiring costly repairs.
Seasoned RV owners also recommend inspecting the roof after every extreme weather condition. For example, one must assess the RV roof after heavy snow or severe storm.
Exposure to extreme weather and climate conditions can shorten an RV roof coat’s longevity. Hailstorms, strong winds, dusty environments, and heavy rains can also increase wear and tear. Hence, people might need to apply a new camper roof sealer sooner than later.
What should I coat my camper roof with?
RV owners should coat their camper roof with a product compatible with the roof material.
- Many RVs have an ethylene propylene diene monomer (EPDM) or thermoplastic polyolefin (TPO) roofing. It would be best to use an EPDM roof coating for these motorhomes. This roof sealant is weather-resistant, UV-resistant, and has exceptional elastomeric properties.
- On the other hand, metal roofs should have a coating of metal-specific sealants.
- Fiberglass roofs require a different product to ensure maximum adhesion and surface protection.
- An all-purpose roof sealant is an excellent buy because it is compatible with most materials, such as metal, glass, wood, ceramic, concrete, brick, and plastic.
Besides material specificity, RV owners must also use a roof coat with excellent elastomeric properties to enable the sealant to withstand extreme temperature variations.
What is the longest lasting roof coating?
Sprayed polyurethane foam coating is the longest-lasting roof coating, reaching more than 50 years with the correct installation.
Adding an elastomeric topcoat to the foam layer can extend its longevity by 20 years.
On the other hand, silicone spray coatings can provide up to 50 years of roof protection. Unsurprisingly, many people use silicone as a sealant for RV roof. Ethylene propylene diene monomer (EPDM) roof coatings also last 50 years, relying on their elastomeric properties to ward off premature wear.
How to seal a camper/trailer/RV roof?
Sealing the roof of your camper, trailer, or RV is actually an activity that you can do on your own. The first step, in this case, is to clean the roof thoroughly. Your goal here is to get rid of all the dirt particles. Dry the roof completely. After that, your next step is scraping old rood or debris.
Be extra cautious when you are performing this step as it might punch a hole or elongate a tear in your RV roof. Check with your dealer so you can determine the specific sealant that is compatible with your RV roof. You should then wear gloves. Use a trowel or paint brunch to apply the coating into your RV roof evenly.
Seal anything that sticks through your RV’s roof, including vents and antennas. Note that such areas have the tendency of developing small leaks, causing a gradual damage to your RV. Coat the seams well. Make sure that you cover all seams, instead of just the damaged parts. With that, you can have an assurance that leaks will be prevented.
In case your roof is either torn or ripped down, it is advisable to buy the fiberglass repair tape. You should then spread your chosen RV sealer over the part that requires a patch. Put one piece of the tape over the problematic patch. You should then cover it by applying more sealer.
