Why You Need Roof Coatings for RV

Applying camper roof coating is part of the periodic maintenance that you need to perform as an RV owner. It may not seem like the most urgent item on your to-do list, but waiting until there are cracks or leaks in your roof is asking for trouble.

It can be a tedious task, but it needs to get done. Here are a few reasons why you need RV roof coatings.


The coating on your RV roof will eventually wear out. When it does, it will be prone to leaks and cracks. Keep rain, snow, and heat outside where they belong by applying a fresh RV trailer roof coating whenever necessary.


A properly coated roof gives your RV an extra layer of insulation against the heat. Your air conditioning unit will work better too. Maintain your RV’s roof coating to make sure that temperatures inside your RV stay comfortable.

Protection from Dirt

Roof coatings protect your roof not just from heat and UV rays, but dirt as well. Dirt is a lot less likely to stick to your RV’s roof if it has the right coating.

Securing Electronic Equipment

Appliances don’t do too well in harsh temperatures. They also run the risk of being thrown around as you travel in your RV. Roof coatings can be used to secure electronic equipment and patch up vents that are exposed to cracks or tears in your RV.


RV roof coating will protect your roof from corrosion saving you from expensive repairs and time-consuming replacements.


The coating material will affect how hot it gets inside the RV. You might need an AC to keep cool in the RV, but it will cool more efficiently and cut running costs if your roof absorbs less heat.

UV Rays

Sun exposure is not something you can avoid. UV rays can cause the finish of your roof to crack, dry, and fade. A roof coating is like sunscreen for your RV.

Factors to Keep in Mind When Choosing A Coating For RV


RV roof coatings depend more on your needs and less on expenses. While silicone or metal coatings are more expensive than rubber, the best thing to do is to purchase a coating based on the features you need. Research on the best roof coating for campers to avoid buying the wrong coating.


You might be looking for a roof coating that doesn’t wear out quickly. A metal coating is the most low-maintenance RV roof coat, but it is also the heaviest.


An RV coating with the longest lifespan may seem like an obvious choice, but you should also keep the age of your RV and its cost in mind.


Most times the coating and the roof are made of the same material.

Types of RV Roof Coatings

RV Roof Paint

A layer of white paint is the best option for those who love camping in hot weather. The color prevents most heat from being absorbed into the roof of your RV while helping to prevent damage and AC usage.

Camper roof paint can also add to the protection of the coat by helping it stay on longer.

Elastomeric RV Roof Coatings

As its name suggests, this is an ‘elastic’ rubber roof coating for RVs. These are also known as rubber coats. Elastomers generally refer to synthetic coating similar to the structure of rubber roof RV coating.

They are waterproof, flexible, and have a thick layer that protects the structure of your roof. Since it is flexible, it moves with your RV so there are fewer tears or cracks. It is also easy to use and will last up to 15 years with proper maintenance.

The RV rubber roof paint is the most commonly used coatings in RV roofs. This type of trailer rubber roof coating is lightweight, low maintenance, and cheaper than others.

They come in two varieties: EPDM (Ethylene Propylene Diene Monomer) and TPO (Thermal PolyOlefin). Both are essentially RV rubber roof coatings, but their characteristics and maintenance requirements aren’t the same.

EPDM Roof Coating For RV

RV roof coating EPDM is a synthetic type of travel trailer rubber roof coating that is characterized by its matte-like finish.

Rubber roof paint for RVs last longer than TPO rubber coatings and are more popular due to their affordability. These coatings are cheap because the manufacturing costs are low. They’re made from recycled tires, sawdust, and slate dust. These materials make your roof immune to cracks, rot, blisters, or tears. This is the best eco-friendly coating for your roof. It is a strong coat that works better on flat surfaces.

Even as TPO coating becomes increasingly resistant to heat exposure, it is still some ways off from overtaking EPDM coating.

The best EPDM roof coatings are high-quality and give you all the benefits of the TPO coating. EPDM is also easier to repair since it only requires a sealant.

The higher cost of EPDM RV roof coating comes from the fact that it needs to be colored after manufacturing. EPDM coatings are originally black when created. The average lifespan of an EPDM coated roof is 20 years.

TPO Roof Coating For RV

TPO is still pretty much in the development phase. As newer TPO coatings are introduced in the market, they could become the most affordable and durable camper rubber roof coating. They are quite similar to EPDM.

TPO coats are shiny. They are also white to begin with so that’s one less cost in the manufacturing process. They are UV-resistant, mold-resistant, dirt-resistant, and can withstand all the harsh vibrations and movements that your RV puts it through.

This type of coating is the most durable coat when it comes to thermal exposure. If you use your RV in different climates, a TPO coating is the best rubber roof coating for RVs.

The average lifespan of TPO coatings is more than twice that of EPDM coatings at 50 years.

Vinyl Roof Coating/PVC Coating

Polyvinyl chloride or PVC roof coatings can be welded to the RV roof. They are resistant to fire, chemicals, wind, and weather which makes them a long-lasting and highly durable option.

Their lightweight coat is best if you want an easy application. PVC is also a recyclable, eco-friendly product. However, it is relatively more expensive than other coatings.

Acrylic Coating

Acrylic is affordable but requires two coats: a primer and a fabric reinforcement.

It is also a water-based coating and unsuitable in cold regions where there is a lot of rain. RV roofs coated with an acrylic coating are UV resistant but will weaken after long exposure to rough camping weather. However, if you only camp in summer and in hot regions, then the acrylic coating will be perfectly fine.

With proper care, your acrylic coating will last you 20 years.

Silicone Coating

Silicone coating is the most expensive coating if you compare it based on its price per gallon. However, it is not that expensive if you consider that you will need fewer coats and no primer when applying it.

Silicone is also better at being resistant to something called “ponding water” which means it doesn’t get damaged by water that collects on your roof. Just make sure to dry the coating properly and you’re done.

However, the catch with silicone coating is that you cannot use it unless the roof of your RV is also made out of silicone.

A silicone roof is highly reflective, weatherproof, and stays elastic throughout its lifetime. A good silicone coating can last you up to 15 years with the right maintenance and periodic inspections after harsh weather conditions.

Liquid Coating

A liquid coating is EPDM liquid rubber roofing for RVs. It has all the features of a rubber coating but it is one step ahead with its liquid consistency.

It can be applied on any type of roof and also self-levels. To use it, you only need to remove the previous layer of sealant before applying the liquid coating.

Any unused leftover product expires within a year so make sure not to buy more than what you need.

Urethane Coating

Urethane is the most durable of all coatings. It is also quite expensive.

It needs to be applied in two coats but doesn’t entail a lot of time or effort on your part. It’s resistant to impact, UV exposure, and moisture.

It has a rather unpleasant odor that disappears after the coat has dried.

RV Sealing Tape

It fixes cracks, blisters, and tears on the roof permanently. It also lasts for a long time.

A sealing tape is similar to adhesive tape but instead of taping together paper, it helps seal cracks and leaks on your RV’s roof. These tapes expand and contract with your RV as it moves.

What Material Is Your RV Roof Made Of?


Fiberglass is made of molded fiberglass or reinforced plastic which is embedded with glass fibers. It is low maintenance, weighs heavily, and hard to the touch.

Fiberglass roofs last for 10 to 20 years.

The disadvantage with fiberglass is it’s prone to oxidation which turns the coating into a fine dust-like residue. A wax coating is one solution, but it only adds to the required maintenance. Wax ensures your fiberglass roof doesn’t get damaged by anything falling on it. Fiberglass is also known to develop hairline cracks after some time.

With all these drawbacks, you may wonder why anyone opts for fiberglass, but it’s very low maintenance and can last longer with proper care. This makes it appealing to campers who prefer to forget about their roof for the most part.


Aluminum has a shiny metallic shiny finish. Metal coatings such as this have similar benefits as fiberglass. They are stronger, low maintenance, highly durable, and can last for up to 10 years without repairs.

However, they are heavier and hard to the touch. Aluminum is also more expensive to buy and install. Since it is metal, it is inflexible and will not expand and contract with your RV’s movement. Therefore, there is a greater tendency for aluminum roofs to become cracked. Unfortunately, leaks in this material don’t show up immediately until the damage becomes bigger.

Aluminum roofs also absorb more heat than other materials.


The biggest advantage of EPDM and TPO roofs is that they are the least expensive. They are also easy to install and repair. These are lightweight materials that don’t get scratched, scuffed, or dented easily.

Tips to Increase the Lifespan of Your Motorhome Roof Coating

  • Put a cover over your RV whenever you’re not using it.
  • Check for leaks particularly after harsh weather conditions.
  • Attend necessary repairs right away.
  • Clean the roof as often as possible.
  • Read the user manual for additional care instructions.

What’s the Difference Between Coating and Sealant?

Coating covers the entire roof and is applied periodically. It is part of the maintenance you need to perform for your RV. Sealants are used to address and resolve cracks, tears, or damage to the RV.


There’s a good reason why a lot of RV owners spend generously on their RV roof. Just like the roof in your house, an RV roof is invisible until it needs repairs and water starts pouring through the ceiling.

Not all RVs are the same. There is no universal solution for the best RV roof coating. The best RV roof coating takes into account the material of your RV’s roof, the amount of energy you are willing to put into a new coating, and the weather where you’ll be taking your vehicle.

If you’re reading this article, it means you’ve either already had an issue with your RV roof or you’re taking all the precautions for your first trip. Either way, we hope we made it easier for you to choose the best roof coating for RV with our RV roof coating guide.
