The 6 Best RV Roof Sealants: Product Reviews
1. EternaBond RV Tape – Best Overall
The EtarnaBond RV tape is a brilliant and easy-to-use tape sealant that can help you in a pinch or over the long term. This tape comes in a 50-foot roll and is easy to take with you wherever you go, making it perfect for emergencies.
This sealant tape is made for many uses and can stick to almost any surface, including all RV roof types. Since this is a tape, it is easy to apply to the exact area you need. It creates no mess and needs no time to cure or dry before withstanding even the harshest of weather.
This tape is also unlikely to let you down in extreme heat as it will expand and contract with the rest of your roof.
2. Flex Seal Liquid Rubber – Runner Up
The only reason Flex Seal Liquid Rubber is another sealant that you can apply to almost any material. You can apply this sealant to any surface using a couple of methods, including pouring, brushing, and rolling.
This sealant is UV resistant, flexible, and watertight, making it perfect for any RV roof cracks, leaks, or gaps. This sealant does take a bit of time to fully dry, but once it is on your roof will be water and airtight, making it perfect to seal the area around your AC or any other cracks or tears.
An added benefit to using this sealant is that it prevents rust and corrosion if you are worried about that.
3. Dicor Self-Leveling Sealant – Best For Aluminum Roof
Dicor’s self-leveling sealant is the best Aluminum RV roof sealant we have reviewed thus far. Applying this sealant is straightforward, and the sealant becomes water-resistant in as little as 4 hours after application, meaning that you do not have to worry about coming rain.
This sealant is excellent to use on most materials, but we recommend it for Aluminum roofs due to its self-leveling, which allows you a clean finish that gets into all the places you need. If you have previously used a sealant that is now coming loose, you don’t need to remove it to use this, as it easily applies over previous layers.
4. Heng’s Rubber Roof Coating – Best For Rubber Roof
Heng’s rubber roof coating is a sealant specially designed for use on rubber RV roofs. This sealant can resist cracking, withstand impact, and is made from non-toxic materials to keep both you and your RV safe.
This sealant is easily applied over your whole roof using a paint roller, and you can use a small brush for targeted areas like vents and cracks. This sealant can also expand, contract, and stretch with the roof, which is why it is so effective. The UV-resistant properties of this sealant also mean that it can withstand harsh sunlight.
5. Premier Pro Products RV Roof Sealant – Best For Fiberglass Roof
The Premier Pro roof sealant is a self-leveling sealant that is easy to use and perfect for fiberglass RV roofs. This sealant does not require a caulk gun to use either, as it comes in a self-sealing pouch, and you only need to apply the right amount of pressure for it to come out.
This sealant is also used on many surfaces and is considered contractor-grade quality, and some even use it on industrial buildings. Once you have applied this sealant, it becomes tack free after as little as 1.5 hours, making it much faster acting than most other RV roof sealants.
6. Liquid Rubber RV Roof Coating – Best For Whole Roof
Liquid Rubber’s RV Roof Coating is the best sealant for more significant projects like sealing your entire RV roof. This sealant is easy to apply by just using a paintbrush or roller, and it does not require you to use any masks as it is non-toxic, environmentally friendly, and safe for pets and humans alike.
This sealant comes in a 5-gallon size to ensure you have enough to make your RV properly waterproof. Not only is this sealant great to keep air and water out of your RV, but it is also UV resistant and solar reflective, meaning that it does not take damage from sunlight, nor does it allow your roof to become hot and heat your RV.
Buyer’s Guide
Naturally, not all RV sealants are the same, and it saves you money if you do research and buy the correct one the first time. Some of the aspects that can hinder or enhance the sealant’s effectiveness include the roof material, the drying time, and the application process.
RV Roof Material
You must ensure you buy the correct type of sealant for the roof you want to use it on. If you buy a sealant that is not compatible with the material of your roof, you could damage the roof, have the same problems, or waste money on a product that doesn’t work. When buying sealants, there is usually a list of materials it is compatible with in the product’s description, be sure to read it carefully.
Sealant Drying Time
If you live in an area known for bad weather or a lot of rain, you need to be sure you buy a sealant that works fast. The alternative to a fast-acting sealant is a garage with enough space for an RV. If you apply a sealant to the roof of your RV and it does not have time to dry before the rain, the sealant could wash off, meaning you have to start again, or your RV might sustain damage.
Application Process
The application process of a roof sealant isn’t always easy. Not only might you need special tools, but you might also have to do many coats, meaning that you will have to wait a long time before you complete the job. If you want to apply the sealant yourself, you must ensure that you buy one that is easy to use.
You must also consider the amount of sealant you will need to complete your task. Some sealants come in larger containers or don’t need many coats.
Water Resistance
One of the main reasons for applying a sealant to an RV roof is to seal it off and keep water out of the interior. To avoid wasting money or doing extra work, you must research the water resistance of all the sealants you consider buying. Some sealants require an extra coat of a different kind to become water-resistant. This tactic is an easy way for companies to make you spend more money.
UV Resistance
If a sealant is not UV resistant, the chances are that it will not last long in dry, hot, or sunny conditions. If you want to ensure that you buy a sealant that will last and continue to do its job for a long time, you will need to research the UV resistance of a sealant before finalizing your purchase.
Durability
Along with the UV resistance is the general durability of a sealant. If you want to seal holes, crack, or tears in your RV roof, you will need a sealant that can expand and contract as the RV heats up and cools down. Sealants that can not stretch and revert to their original state tend to crack or lift off the initially applied material leaving them useless and your RV with gaps.
Price
Though the price is not always the most significant factor to consider when buying roof sealants, there are some things you should always be wary of. Some companies sell sealants cheaply because they require other components to work correctly. In the same breath, some companies will charge you three times the price for the same sealant under a different name.
Reading reviews on a product is essential to ensure that it works properly, and it also helps you weigh up the cost compared to the quality.
What You Need To Do
The type of work you need to do on your RV roof is another factor that can significantly impact the sealant you buy. If you are looking to seal off the gap next to your AC, you can use a sealant that comes in a small package compared to a whole roof coating.
Not only can the amount of sealant you buy change, but the sealant itself can change based on what you need to do. If you are looking to fill in a hole, you will need a sealant that will dry quickly and stay in place, and if you need to seal around a vent, you will need a sealant that is easy to spread with a paintbrush. Be sure to compare the type and amount of sealant you buy to the task you need to do.
Conclusion
If you are looking for an RV roof sealant that is easy to use, works quickly and is compact, we recommend buying EternaBond RV tape. Not only is this tape easy to use and take with you, but it is essential if you need to make an emergency repair and you do not have time to wait for a coat of sealant to dry.
EternaBond RV tape is a quick and, at the very least, semi-permanent fix to any of your sealing problems. This specific tape is also compatible with all the materials used in an RV roof, making it practical for all RV owners.
If having a quick and easy fix to your problem is not enough, you can also buy a UV protector to allow the tape to stay in place even longer. Considering all the sealants we have tested, along with all their features, pros, and cons, EternaBond is the best RV roof sealant overall.
