An RV that isn’t properly sealed can lead to hundreds of dollars in water damage. Therefore, it’s important to protect your RV – and your wallet – in the first place. Resealing your RV isn’t a difficult task and it’s definitely worth the little bit of time that it’ll take.
In order to reseal your RV roof, clean the top of your RV thoroughly to get rid of any dirt buildup. Next, repair structural damage, such as cracks, with repair tape. Then, seal any vents and antenna. Finally, apply a self-leveling sealant that suits your roof type (using the wrong one could cause serious damage).
You’ll also need to ensure that you always inspect all the seams of your RV year-round, and use a sealer to fix up cracks to avoid any future damage.
I’m going to tell you exactly what you need to know about resealing your RV roof:
Benefits of RV roof sealant and coating
There are several benefits that come from RV sealant and coating:
1. It provides structural protection
When it comes to keeping your RV in good condition, structural protection plays a significant role. The good thing about using RV roof sealant and coating is that it helps to keep it in proper condition. The structure of your RV is what keeps it functioning well.

One thing you need to know or already know if you own an RV is that they tend to use a lot of energy. Even when going for short trips, an RV can use a lot of energy which can be quite costly. Luckily, the use of RV sealant and coating can help to reduce too much energy usage.
An RV coating helps to add insulation into the vehicle, which in turn, will help to reduce too much consumption of energy. Therefore, this will help to reduce these energy costs and make it possible for you to save money.
3. Reduces wear and tear
The older your RV, the more it takes a beating on the roof surface. When your RV stays for longer and gets exposed to the outside world, its roof can start to wear and tear which may require repair.
The good news is that RV roof sealant and coating can help to fix this issue. You can consider rubber roofing at the top, which will help to minimize the wear and tear of your RV roof. This will eventually help you save on costs.
4. Temperature regulation
When you apply roof coating on your RV, it will help to form a preventative barrier that will regulate the temperature inside. This will help to keep the inside of your RV cooler during the warmer or summer season and also in the winter.
When the temperature of your RV is well regulated inside, it will help you use less power, mainly because you won’t need to crank up the heating or air conditioning. This will be a win-win situation because you’ll be able to save on costs over a long period.
5. It reduces costs
Generally, the main benefit of RV sealant and coating is that it helps you significantly save on costs. All the benefits we’ve discussed above point to the fact that they minimize your costs and help you save money. When you keep your RV in great shape, you are bound to save money in the long run.
Keeping your RV’s roof properly and preventing any damages on the structure such as warping will help you save a lot of money that would have gone in repairing or roof maintenance. Therefore, you will end up saving more compared to the option of repairs.
Types of RV roof sealant and coating
There are three main types of RV sealant and coating which we are going to discuss in this section. These sealants and coatings are quite efficient, affordable, and beneficial. See them below:
1. Urethane Coating
Urethane coating is one of the most durable options that you can consider. It can be the perfect coating for your RV’s roof. It’s actually quite popular among RV owners and also mobile homeowners. What makes this RV coating stand out is the fact that it has a great structure that works well to protect against any falling branches or other small debris.
It also offers excellent protection on your roof against any other forms or elements that may try to cause it damage. However, it is essential to note that urethane comes at a higher cost. It also requires two coats to be effective.
2. Acrylic Coating
Acrylic is one of the cheapest RV roof sealant and coating, but it offers a good solution for dealing with any gaps on your roof. If you want to prevent further damages to your RV’s roof, you can fully count on the acrylic coating. It’s also ideal for your RV’s structure and it efficiently manages to reflect a considerable amount of sunlight.
The acrylic coating works really well and can help to seal any cracks or leaks on the roof of your RV, thereby preventing water from coming in. The only drawdown with this coating is that it is not durable compared to others on the market. It also requires too much effort in terms of application and can take up too much of your time.
3. Silicone Coating
Silicone coating is one of the most expensive RV coatings on the market. However, in terms of durability, you can fully count on it. The good thing about the silicone coating is that it helps in the prevention of weather degradation, sun, and wind damage. It also prevents your RV from pounding water.
It has an ideal structure that enables it to stay elastic and leaves it intact for a long period of time. The drawdown of using the silicone coating is that it can easily get dirty, which means you need to wash it regularly to ensure it stays in proper condition.

1. RV roof type
What kind of roof does your RV have? This is one of the crucial questions you need to ask yourself before going to buy any RV sealant and coating. Remember, you need to buy products that will work well with your RV’s roof to avoid regrets later on. Therefore, make sure you conduct thorough research and identify a sealant and coating that will be ideal for your RV’s roof.
2. Sealant & coating type
You should note that the sealant and coating are quite similar, but they serve different purposes. Therefore, when buying you should any of them you need to consider the roof type of your RV. A coating helps to protect your RV from damages, it offers insulation, and also adds structural features. A sealant helps to seal cracks, leaks, or patchwork in small areas.
The material that has been used to make the sealant or coating that you’re using will significantly affect its performance. However, when we are talking about tape sealant and pasting sealant, the formulation doesn’t matter as much, due to the quality of the product. Most RV coatings are made from a wide range of materials, which makes silicone the best one for weather resistance even though urethane and acrylic also serve the same purpose.
4. Ease of application
Formulations are quite different in terms of application and the amount of time they take to dry, as well as the number of coats they require to work effectively. Silicone is efficient because it’s easy to work with, dries faster, it’s easy to apply, and only requires a single coat. Urethane and acrylic tend to vary although most of them require a primer coat and several coats to become effective.
