rv roof sealants lg

Your RV is your sanctuary on the road. But a leaking roof is a surefire way to drown all the fun. Luckily, it’s not that hard to reseal your RV’s roof. But what is the best RV roof sealant?

Thankfully, some of the best RV roof sealants and coatings are available on the market. No need to go to a dealer to get your roof fixed, all you need is your trusty RV roof sealant, and some finesse, and you’ll be ready to roll in no time.

Coating a damaged roof can save you money instantly and in the long run as well.

There is no need to postpone getting the roof repaired. You can do it yourself, thanks to some great quality RV roof sealants. I highly recommend you keep one sealant, coating, or at least sealant tape in the RV for emergency repairs.

Types of RV Roof Sealants and Coatings

Liquid – Liquid sealants and coatings are kind of like paints. They both require surface prepping before they can be applied. You will need to clean the roof as well as prime it before applying. This is simply because the liquid sealants take a while to set in and cure fully.

The low viscosity demands you leave the coating alone for at least a couple of weeks before painting the surface. There are different types of liquid sealants and coatings. The best one is silicone-based. There are also acrylic and urethane-based liquid RV sealants. The type of sealant you use matters a lot.

Sealing Tape – What if you don’t have weeks to wait for the liquid sealant to cure? Then you can use sealing tape. There will be no surface preparation needed when you are simply going to apply tape sealants to repair the damage.

The sealing tape has an adhesive that makes a strong bond with the surface of the roof, effectively repairing any damage or cracks. The tape also has elasticity and can expand or contract according to weather conditions. Good quality sealing tapes can last years before they need to be replaced.

Let’s check out the best RV Roof Sealants and Coatings for 2022 and discover which one is a good choice for your RV roof.

25 Best RV Roof Sealants & Coatings for 2022

1. Heng’s Rubber Roof Coat

Heng’s Roof Coat is a fan favorite among long-time RV owners, and for a good reason.

The coating is specially made to be used on RV rubber roofs. It is best used for repairing cracks and tears that formulate on the rubber roof.

The sealant is also great for waterproofing surfaces, especially around air vents, vent pipes, and air conditioners. It is non-toxic and environmentally friendly.

I like the fact that it has some elasticity, and it can expand and contract according to the temperature.

Application is also straightforward; it is malleable and easy to work with. You can also apply it in direct sunlight without the worry of it bubbling under heat. You could use a primer to make the application go even easier (not a requirement though).

The only thing that would’ve made it better was silicone. Heng’s Rubber Roof Coating is acrylic-based, so it won’t last a long time. But don’t worry, it’ll still last years before needing a recoating.

2. Dicor EPDM Self-Leveling Sealant

Looking to have a strong seal along the roof edges?

The Dicor EPDM Self-Leveling Sealant is a product perfect for that. It can form a secure seal on a variety of different surfaces, as well as vents and screw heads. I’ve used it on fiberglass, wood, aluminum, metal, and vinyl.

The sealant comes in white color, which is what most roofs are colored in RVs. It is great for horizontal surfaces but can be a bit runny on vertical ones.

The Dicor EPDM Self-Leveling Sealant is perfect for sealing screw heads. All you need to do is apply a generous amount and let it self-level. It is also the best product for sealing leaks and cracks.

The only downside is the size of the tube. If you have a large RV-based project, you’ll easily use up at least 5-6 tubes of the sealant. This adds up the cost.

3. Rust-Oleum LeakSeal Rubber Coating

Want to stop leaks but don’t want to ruin the color scheme of your RV?

Rust-Oleum LeakSeal Rubber Coating has your back with its crystal-clear formula. The oil-based rubber coating is a great choice whether you are using it inside or outside. The container has 30 ounces of coating, which is more than enough for 40 square feet.

The best part is its curing time of just an hour, which allows you to paint over it as soon as possible.

The Rust-Oleum LeakSeal Rubber Coating gives you a waterproof coating that can resist extreme weather conditions, all the while improving surface insulation.

The seal can be used on multiple surfaces apart from the RV roof. You can apply it on PVC, ducts, metals, and even concrete.

4. KST Coating Premium Elastomeric Finish Coat

KST Coating Premium Elastomeric Finish Coat is a resin coating that becomes rubber-like once cured.

The product offers excellent protection against humidity, mildew, soaps, and algae. The coating is also capable of resisting 90% UV rays and remains flexible even during extreme temperatures.

I recommend doing a double coating of the Elastomeric coat, as it is a bit thin when applied only once. So double coats are essential if you don’t want flaking to happen.

The manufacturer provides a 7-year warranty for KST Coating Premium Elastomeric Finish Coat, always a good sign in my books.

5. Ziollo RV Flex Repair Tape

The Ziollo RV Flex Repair Tape offers a fast route when it comes to repairing RV roof leaks.

It is one of the best RV roof sealants when it comes to convenience. The white tape is around 50 feet long and comes with an adhesive butyl sealant. The tape can be used on rubber, metal, fiberglass, plastic, and anything else you can think of. It doesn’t play well with silicone though.

The package also contains a seam roller that helps in activating the sealant.

The tape is resistant to UV light damage, increasing its lifetime. Keep in mind that the Ziollo RV Flex Repair Seal Tape is quite sticky, so you’ll have to be careful while applying it.

6. Flex Seal Liquid Rubber in a Can

The Flex Seal Liquid Rubber in a Can is a goopy material that is easy to work with. You can roll it, pour it or even brush it on your RV roof. It works well with other surfaces too. If you need a watertight rubberized coating on any surface, this product can do the job.

The Liquid Rubber in a Can forms a watertight coating that keeps water and moisture out.

The product is also non-flammable and UV resistant. I like the fact that the RV roof material is non-toxic and can be safely used inside as well. I recommend at least 3 coats of Flex Seal Liquid Rubber in a Can to create the perfect, watertight seal.

7. Liquid Rubber RV Roof Coating

The Liquid Rubber RV Roof Coating not only works on our roofs but also on a number of different surfaces.

From metal roofs to sheds and from fences to foundations, it can create a flexible solar reflective coating on any surface. You can even use it on concrete or wood, and it will work perfectly well.

It is also a great way to ensure the summer sun doesn’t scorch your RV. It is UV resistant which means the sun won’t be able to damage the product either.

Applying the coating is also easy; you can use a brush, a roller, or even a paint sprayer. For this, like any other liquid rubber coating, I recommend at least two to three coats before the waterproof membrane forms.

8. Rubberseal Liquid Rubber Protective Coating

This liquid rubber protective coating can be used not only on RV roofs but on all kinds of roofs. After application, the liquid rubber sealant turns into an elastic acrylic coating that is surprisingly sturdy. The water-based formula is easy on the surface and won’t cause any formation or buildups.

If you’re looking for the best value for money, the Rubberseal Liquid Rubber Protective Coating can easily spread at the rate of 60 ft.² per gallon at 20 Imperial mils. In layman’s terms, it can spread on a large surface area.

9. ToughGrade Self-Leveling RV Lap Sealant

ToughGrade Self-Leveling RV Lap Sealant is specially designed for rubber roofs and prevents sun damage, discoloration, and even leaks.

It is designed for horizontal surfaces, and this is how it self-levels into the surface. This is also how it can efficiently seal any damages or cracks formed on the roof surface.

The formula can also withstand extreme weather conditions, and its application is straightforward and easy. The only downside is that it has a slight white color, which may look great on a colored RV roof. It also cannot be used on vertical surfaces.

10. Premier Pro Products RV Roof Sealant

The Premier Pro Products RV Roof Sealant can be applied on rubber, void, metal, and even asphalt. The product comes in a pouch-like package, which makes it a lot easier to apply and reseal safely. You won’t even need a caulk gun to use this roof sealant. The roof sealant is also self-leveling, so it doesn’t need a lot of input from you either.

All you need to do is apply the product and wait for it to self-level, and you’ll get a smooth finish without much effort.

It also has pretty good tensile strength and elongation properties, so it can expand and contract according to the temperature.

The only downside is that it is not designed to be used in extremely cold temperatures, so if your weather is often going below freezing temperatures, Premier Pro Products RV Roof Sealant is not the best choice.

11. Dicor RP-MRC-1 Elastomeric Coating

Walking into the specialty category, the Dicor RP-MRC-1 Elastomeric Coating is made to be used on metal or fiberglass roofs. The coating contains a hundred percent acrylic isomeric resins and has a strikingly bright color to it.

After application, it will form an elastic rubber-like coating on the roof which can move seamlessly during your travels.

The expansion and contraction of the coating helps extend the life of the roof as well as the product, reducing the likelihood of cracks and leaks from forming. Two coats of the Dicor RP-MRC-1 Elastomeric Coating are recommended for creating a perfect seal.

Need a quick and easy repairing solution? The Eternabond RoofSeal Sealant Tape is what you’re looking for.

It is not designed to be a permanent solution to your roof leaks, but it will help you make urgent repairs until you can find a long-term solution.

I recommend the EternaBond RSW RoofSeal Sealant Tape simply because it can adhere to a number of different roof types. TPO, EPDM, metals, plastics, you name it, it can stick to it. The 4-inch wide tape comes in strips.

The strips have a primer applied for a stronger bond with the surface. The Eternabond RSW-4-50 is also a great option.

13. Geocel Pro Flex RV Instant Repair

If you’re on a budget and need to repair leaks and cracks in your RV roof, this one is one of the best RV/camper roof sealant.

The only downside is that it is specifically designed for metal roofs, but it can still work on wood, sheet metals, steel, and vinyl as well. The instant repair in the name is true. The formula works fast and stops leaks in no time and is also great for patching up seams, splits, holes, tears, and breaks.

After application, your RV will be ready in under an hour to hit the road. It is the best sealant if you need to move your travel trailers urgently.

The rubberized finish not only protects your RV from relentless sun rays but also provides slight soundproofing. It is a must-have if you hate rain and hail hitting on the metal roof.

Frequently Asked Questions

How Often Should You Seal Your RV Roof?

This depends on how damaged your roof gets as well as how sturdy your initial coating was. I recommend checking the condition of the roof every 3-6 months. If you see visual damage, cracks, or flakes forming, it’s time to seal. While a good quality sealant can last up to a year, other RV equipment has varying lifespans.

Here’s a recent article that talks about it.

Is RV Roof Sealant Self-Leveling?

Yes, Most RV Roof sealants are self-leveling and can only be used on horizontal surfaces. However, you should take a look at what the manufacturer says, as some may need leveling assistance from you. Using liquid sealants on a vertical surface isn’t a good idea.

How Do You Reseal an RV Roof?

You can do this by getting a product listed in the best RV roof sealants.

It also depends on the material of your RV roof. Don’t get a sealant specially made for rubber roofs and apply it on metal. It can work, but why take a risk.

But for most of you, you’ll be buying a liquid rubber product in a gallon container. So here are the steps involved:

  1. Clean the roof thoroughly to remove any dirt, leaves, or debris
  2. Use repair tape on any cracks
  3. Seal around vents or antennae with silicone-type roof sealant
  4. Tape plastic tarps to the sides, front, and back of the RV to prevent sealant from dripping down the sides
  5. Pour a self-leveling rubber coating onto the roof, starting at the front and working your way back to the ladder (so you can climb down without tracking through the coating)
  6. Use a standard long-handled paint roller to spread the coating evenly.
  7. Do I need a 2nd coat? For RVs older than 10 years, it may be a good idea to apply the 2nd coat after the 1st coat dries.

Don’t have a rubber roof?

If your roof isn’t currently rubber, it’s most likely fiberglass. In that case, the steps are basically the same, but you’ll want to use silicone sealant instead of rubber.

Have a metal roof?

Older RVs often have aluminum roofs. In this case, you’ll want to use something specifically for metal, such as Dicor Metal RV roof coating from Amazon.

You can also invest in a good-quality RV cover to minimize general wear and tear.

A recent article explores the world of RV covers, how easy they are to take on and off, how much they actually help with the lifespan of your roof and RV, and whether they are really worth it.

Just click that link to read it on my site.

Seal Your RV Roof For Life

Conclusion

This concludes the best RV roof sealants and covers list.

I hope you’ve found the perfect match for your roof, and it will only extend the life of your vehicle. I recommend getting a normal liquid coating and a spray or tape for instant repairs.

This way, you’ll be able to patch up any damage quickly without the worry of damaging anything inside the RV. I also recommend reading up on other best RV roof sealant reviews to gain even more insight.

It is always better to periodically check the roof of your RV, clean it thoroughly, and, if possible, apply a new coat of sealant. Preventive action is better than damage control.
