What is an RV Roof Coating or Sealant?

An RV roof coating or sealant is a product that you use for the roof of your RV to give it a new shine. It adds an extra layer of protection to an already completed roof which helps in extending its life.

How Does RV Roof Sealant or Coating Work?

A good quality RV roof coating or sealant works by reducing the transfer of heat into the roof of your camper. It also lessens thermal shock which is caused by the expansion and contraction of the membrane of your RV roof. By doing this, it protects your RV roof and extends its life.

This roof coating for RV will help mitigate leaks in your rig. It will make sure that all seams are covered so that even if there’s a heavy downpour, no amount of water or moisture can make its way inside your camper.

Your RV roof coating also enhances the overall look of your rig. Reflective coatings or sealant also lessen your energy costs.

How well an RV roof sealant or coating performs its job will depend largely on which material your RV roof is made of and the type of roof coating that you choose. The best RV roof coating is one that is compatible with your camper’s roof material so that it can do what it’s supposed to do.

For example, you have a roof that’s made of metal, you can use a liquid or rubber roof coating for RV. If your roof is made of plastic, then it is recommended that you get a rubber coating. This is why it is important to know more about the different types of RV roof coating and sealant and how each one works with a particular type of material used for RV roof.

Types of RV Roof Sealant & Coating

There are various types of RV roof coating and sealant. You have to have a basic understanding of each type when choosing the best RV roof coating. As mentioned earlier, the performance of a specific type of RV roof coating would depend on its compatibility with the material used for your rig’s roofing so you have to be careful in choosing the right type of roof sealant and coating.

Rubber Coating

Rubber roof coating is the most common RV roof coating used by RV owners. There are 2 variants of rubber roof coating: one is made from thermal poly Ofelin and the other is made from ethylene propylene monomer.

These 2 variants differ in terms of their application and maintenance that’s why you need to check the product info to know how to use the particular variant of rubber coating that you’re getting for your roof.

Acrylic Coating

A more affordable option for RV owners that still provides good protection for the roof is the acrylic coating. This type of coating has good reflectivity and gives adequate protection from leaks and moisture.

Acrylic coating is resistant to harmful UV rays. In order to get this kind of protection, you need to apply two coatings – one for the primer and the other for the reinforcer.

However, there have been instances when acrylic coating failed in handling ponding water over the roof which leads to peeling or degradation of the RV roof coating and eventually, there were leaks inside the rig. So if you frequently travel to very wet climates, this might not be the best option for you.

Silicone Coating

Silicone RV roof coating is a more expensive option for RV owners but the price is worth it because of the benefits that it offers. It is sold on a per gallon basis.

You just need a single coating of a silicone RV roof coating which makes up for its price. You don’t need a primer for this as a single coat is enough to get the job done. This also means it consumes less time during the application process.

Silicone RV roof coating is weatherproof, has a high reflectivity and wind degradation. It also resists ponding water and is able to retain its elasticity for a very long time. You can be sure that it won’t easily become brittle or hard and can stand the test of time. With these qualities, it is a very good investment and provide good value for money in the long run because of its excellent performance.

Liquid Coating

A liquid RV roof coating is naturally resistant to water. This property makes it reliable in preventing corrosion.

Many RV owners also recommend this type of roof coating because it is very easy to apply. You apply the coating in the same manner that you paint your walls. Or you can just pour it directly over your roof then spread it evenly with the help of a rolling brush.

Liquid coating also adds to the aesthetic appeal of your RV’s roof and provides it with good protection from UV rays. That is why you can rely on it to help prolong the life of your camper.

Fiberglass Coating

Fiberglass RV roof coating is a good choice because it requires less maintenance compared to other types of RV roof coating. However, its application on your roof requires more effort. It is also more expensive. This type of coating adds more weight to the roof of your rig so it might cause some issues if your roof’s structural integrity is already compromised to begin with.

Urethane Coating

Urethane coating is more durable than acrylic and silicon coatings. It has properties that make it reflective and resistant to UV rays. It can also withstand pools of water on your roof. It is also perfect to use on the road because it has a good resistance to impact. You don’t know what might fall on your roof as you travel so it’s good to know that your urethane coating will protect you from these elements.

The downside to this type of RV roof coating is that it is expensive. It also has a strong odor. You have to install it in a place where there aren’t many people around so that they won’t be exposed to the unwanted odor.

As you can see, there are different types of RV roof coating that you can buy in the market. There are advantages and disadvantages in choosing one type over the other. But in the end, you have to choose the best RV roof coating that suits your rig and will give you the most number of benefits.

Features to Look for in RV Roof Sealants

With the added protection that RV roof sealants and roof coatings provide to your rig, for sure you’re very excited to get the best RV roof coating and best RV roof sealant in the market. But what makes a best RV roof coating? Here’s our guide to help you choose the best RV roof coating for your rig.

Type of RV Roof Sealant & Coating

As mentioned earlier, there are various types of RV roof sealants and coatings. The most common RV coatings in the market are rubber, silicone, acrylic, fiberglass, urethane and liquid coatings.

Each one has distinct properties and come with its own set of advantages and disadvantages. Choose the one that offers more benefits for your situation.

Your Roof Material

RV roofs can be made of different materials. These can be EPDM rubber, aluminum, fiberglass, or rubber TPO. What your rig’s roof is made of will determine which kind of roof coating and roof sealant you can use on it.

So you better check what material your roof is made of before you buy the best RV roof coating for your rig. Check your RV manual or the manufacturer’s website for more information.

If your RV roof is made of aluminum, it rarely needs a new coating because it already has innate weatherproof and durable properties.

You have to make sure that your chosen RV roof coating will work well on the material of your RV roof. You can be assured that there’s a strong bond between them and you’re not just wasting your money.


Durability means how long the roof coating or roof sealant will last before you need to reapply another one. It must have the elasticity and tear resistance to be able to stay glued to your roof no matter how many twists and turns you make.

You can check the product information regarding the recommended application. There are some manufacturers that will advise you to reapply the coating every 2 years while there are some that need to be reapplied every 6 months.

This tells you a lot about the durability of the product. The longer it takes to reapply another coating, the more durable it is.

Application of the roof sealant or coating can take a whole weekend and it is not something that you’d want to do frequently when you can use that time for camping and enjoying the outdoors. So you’d want to choose a more durable RV roof sealant or coating.

UV Resistance

The roof of your RV is exposed to the sun for a long period of time. You can’t always put a cover on it to shield it from the harmful rays of the sun and over time, this constant exposure to heat will cause wear and tear on your camper’s roof.

Without a good quality roof coating, this wear and tear will happen sooner than you want. Applying a roof coating should be a part of your maintenance for your RV. And it would help a lot if your coating comes with UV protection.

You can get this information from the product description. In case the manufacturer doesn’t mention this in the product info, then it would be to your interest to avoid buying that roof coating. The best RV roof coatings offer good resistance against ultraviolet rays and give your roof the protection that it needs.

Ability To Repel Water

A good quality RV roof sealant and coating must have a water repelling property. You can’t help it when the raindrops keep falling over the roof of your rig. Most of the time, water will tend to accumulate creating a pool on your roof.

This is bad for your roof because it will cause peeling of the paint and coating. Water and moisture will also find their way inside your rig causing more damage to your interiors.

This is why you need to invest in a good quality roof sealant and roof coating which can repel water. The best RV roof coatings have an excellent natural ability to resist wetness because it is what they have been designed to do.

You can read the customers’ reviews about the product to get an idea regarding the roof coating’s water repelling property. The experiences of the consumers will let you know the effectiveness of the product because it is only through experience that you will know if the roof coating is really up for the job.

Ease of Application

By ease of application, we mean the time you need to spend on applying the roof coating or sealant. It also refers to the number of coats you need to apply to achieve its optimum level of performance. A roof coating is also easy to apply when you can just use a paint roller or squeegee to spread it evenly on the roof.

There are some roof coatings that would require you to put a primer first or other solution before applying the roof coating. This is done to ensure that the coating will bond securely with your roof. Other roof coatings require 2 or more coats to be able to provide you with the protection that you need. This will also have an impact on the overall cost of coating your roof.

Of course, you’d want a roof sealant or coating that would require minimum amount of time and quantity to get done.

Chemical Composition

It is important to consider the chemical composition of the roof coating or sealant that you’re buying because you need to know that it’s safe to use. Manufacturers also state the safety precautions needed when applying their product.

You would want a roof sealant or coating that uses non-toxic chemicals so that you can be sure that it’s safer and easier to use. It is also a big plus when the chemical composition of the sealant and coating is environment-friendly. This way, you don’t contribute to pollutants in our surroundings when applying the coating and when the coating flakes off the roof.

Cure Time

This refers to the amount of time that it would take for the coating or sealant to completely dry or set on your roof s that you can use your rig again.

There are roof coatings that only take 2 to 3 days to complete the application process while some would take a whole week before you can take your rig on the road again.

Cure time depends on the weather conditions and the type of roof sealant and coating that you want. When the weather is hot, curing time is usually shorter. So it’s a good idea to schedule your roof coating during the summer.

Wrap Up

Getting a good quality roof coating and roof sealant is an essential part of your RV maintenance. It will help prolong the life of your roof and also your camper as a whole. This is why you should get the best RV roof coating so that you can protect your investment.

Frequently Asked Questions

What Is An EPDM Rubber Roof?

An EPDM rubber roof has been a trusted choice for over 4 decades now among RV manufacturers especially those making low-slope roofs. EPDM stands for ethylene propylene monomer. The main ingredients, which are ethylene and propylene, are derived from natural gas and oil.

It is a synthetic material that’s available in the market in strips usually with a thickness between 45 to 60 millimeters and length ranging from 7.5 feet to 50 feet. When putting up an EPDM rubber roof, the edges need to be secured by using a specially formulated tape or liquid adhesive.

How To Apply An RV Roof Coating?

Different types of roof coatings and sealants have different requirements for their proper application. You need to follow these steps carefully to ensure a long lasting bond between your roof and the sealant.

The first thing you have to do is determine the area of your roof. You need to measure how much square footage it covers so that you know how much roof coating you need to buy.  

Take note also of the application requirement of the roof coating that you will buy. If it requires two coats, it means you need to double the measurement of your roof so that you will have enough supply for the entire application process.

Before applying the coating or sealant, you need to prep your RV roof. If the old coating or sealant on your RV’s roof is already flaking, you should remove it carefully. Make sure your roof is clean and free from dirt so that nothing will get in the way when you apply the coating. This will help ensure the effectiveness of the sealant.

You can have your roof power washed or you can scrub it with soap and water to remove all the dirt on top of it. Then you have to wait for it to be completely dry before you apply the roof coating or sealant.

RV sealants or coatings may contain flammable properties so make sure that you remove any items that can be a possible source of ignition to avoid danger.

When you’re ready to apply the coating, take off your shoes as they can also be a source of dirt and debris. You can just wear your socks or use shoe covers when you go up the roof to start applying your coating.

Start by applying a light coat on your roof. The goal here is for you to cover first all the seams, depressions, and other bumps and humps on the roof including the skylights, pipes, and vents.

You should also apply a light coating on those areas which would be hard to reach when using a roller brush. As for the vertical parts and rounded edges of your roof, you can use a brush to put on a light coating on these surfaces.

Let it dry for about 3 hours. Then, with the help of a nap roller, you can put on more coat on the whole surface of your roof. Let it dry for 48 hours. After this, you can apply a finishing coat (only if needed) using a longer nap roller. Wait for it to dry completely before taking your RV on the road again.

How to seal a camper/trailer/RV roof?

This is a good DIY project for RV owners. It is a relatively simple process that’s why you can definitely o this on your own.

Before buying a roof sealant, you should also check with your dealer or your manufacturer’s website which RV roof sealant is compatible with your rig.

The first thing you have to do is make sure that your RV roof is completely free from any kind of dirt, debris, and unwanted particles. You can use water with soap for cleaning. Then, allow it to dry completely.

Then, carefully scrape off any old rood or debris that you find on your roof. Take extra care not to cause a hole or tear in your roof.

When applying the roof sealant, you should wear your gloves. Use a paint brush or trowel to apply the sealant on your roof evenly.

You should seal anything that sticks through the roof of your RV. This includes your antennas and vents. Make sure that all the holes and seams are covered completely or else they will cause leaks later on as water makes its way through those tiny holes.

Do not just focus on the damaged parts, make sure you apply the sealant on each hole and seam on your roof. This is how you can prevent leaks from happening.

If a portion of your roof is ripped or torn, use a fiberglass repair tape before you apply the roof sealant over the patches.

Is Flex Seal good for RV roofs?

Yes, Flex Seal is good to use on RV roofs. Flex Seal is a versatile product that you can use for your roof, skylights, vent pipes, and roof gutters.

It has properties that make it capable of adhering to different kinds of roof materials. But Flex Seal is recommended to be used on RV roofs made of fiberglass or metal. If you have an EPDM rubber roof, you better stick to rubber coatings to guarantee its effectiveness.

Flex Seal has a natural ability to seep into holes and cracks and seal them shut. Once it is fully dry, it retains its elasticity very well that’s why it is very flexible. It is also durable and water resistant. This is what makes it so effective and a trusted product by many RV owners.

How do you clean an RV roof before sealing?

As mentioned earlier, you can either have your roof power washed or you can also clean it by yourself by using soap and water. Make sure you remove all the dirt, debris, and unwanted particles that can be found on your roof so that they won’t affect the effectiveness of the roof sealant.

Can you walk on the roof of an RV?

It depends on the material used for your RV roof. If it is made of fiberglass, then yes, you can walk on it. Fiberglass is strong so it won’t break or bend when you walk over it. Just be careful because it can get slippery when it’s wet.

Be careful because some manufacturers use thin plywood for the roof so that they can cut back on the cost and weight. If your travel trailer happens to be one of these, then it is not safe for you to walk on your roof.
