Considered by many as one of the very best RV roof coatings out there, Proguard Liquid Roof can be applied over rubber, metal, fiberglass, wood, and fabric. It’s an excellent product that is highly durable.

This makes it an ideal choice for your RV roof, being able to withstand motion and vibrations, as well as huge temperature fluctuations from minus 60 degrees Fahrenheit up to 300. It won’t crack or dry out and even comes with a five-year warranty, although many users find it’s still in great shape over ten years down the line.

Application is fairly straightforward and this product has the bonus of only needing one coat – so it’s also a great time saver. Coverage is estimated at around 42 square feet per gallon, so, on an eight foot wide roof, you’ll get about five linear feet per gallon. It goes on pretty much like paint and you can apply it with a sponge, roller, or brush.

While this product waterproofs immediately on application, you’ll need a dry 24 hours to apply it. Tack-free in 24 hours, a full cure takes seven days, so it’s not a last-minute job.

Thanks to its one-coat application, five-year warranty, and fantastic reputation, this is by far one of the easiest and most highly recommended RV roof coverings around, making it worth its somewhat elevated purchase price.

Buyer’s Guide to Buying the Best RV Roof Coating

When you’re on the lookout for the best RV roof coating for your rig, there’s plenty of things you’ll need to bear in mind. To help you focus on what you really need from your RV roof coating, we’ve compiled a handy list of the most important considerations you’ll want to focus on.


While RV roof coatings aren’t exactly cheap, they are a lot cheaper than replacing your entire roof. They are also cheaper than redecorating and restoring your interior after a leak. Everyone has their own budget they need to stick to, although you’ll often find that more expensive RV roof coatings require fewer coats which will in turn save you time.

However, before opting for that large five-gallon pail that costs a little more than one-gallon of the premium stuff, just double-check how many coats you would need of each product, factoring in any recommended primers. You may find that some RV roof coatings that cost a lot more per gallon actually work out cheaper if you only need one coat.

Type of Roof

Always make sure that your RV roof coating is compatible with your RV roof type. If it’s not, you could damage your roof membrane – a costly mistake well worth avoiding.

If your coating is incompatible and fails to correctly adhere, you could not only ruin your vacation, but have a huge amount to repair, redecorate, and replace inside your coach due to water damage.

Rubber roof types often throw up the most compatibility issues, so if you have any doubts whatsoever, always double-check with the manufacturer before using. You may need a special primer or a different type of roof coating all together.

Ease of Application

While most RV roof coatings go on pretty easily, a lot like painting, the thicker premium versions tend to be easier to deal with. They also tend to require fewer coats which in turn means less work for you.

Most manufacturers have detailed application instructions with photos or videos available online. Don’t hesitate to check these out to get a better idea of what you’re getting yourself into. Most RV roof coatings can be applied with a brush, roller or sponge.

Another important aspect that you’ll need to pay close attention to is what kind of conditions you’ll need to apply your product in. Some RV roof coatings can only be applied above 50 degrees Fahrenheit for example, while others require 24 hours rain free or low humidity.
These constraints can rule out applying certain RV roof coatings in certain areas for whole months at a time.

Cure Time

Some RV roof coatings are very quick-drying and have rapid full cure times of around 24 hours. Others can take around seven days.

If your RV roof coating requires several coats, this can also affect your cure time, as can humidity levels and the weather. For example, some products are to be applied with some direct sunlight available for at least part of their cure time, or else the curing process can take considerably longer.

For a better idea of how practical a particular version will be for your needs, check out how quickly it becomes waterproof and hard to the touch. While some products have a long full cure time, they can be exposed to water just a few hours later. As all RV roof coatings are different, be sure to pay attention to each model’s specifics.

Non-toxic Materials

When possible, it is always preferable to purchase and handle non-toxic materials. If you are coating your RV roof in storage, then you may need to wear breathing protection apparatus, or if you have any underlying health conditions.

Opting for non-toxic, environmentally-friendly versions are also safer for nature, plus other people and any animals who may be around when you’re treating your roof.


Highly durable versions will last you anywhere between 5-10 years, although you will still want to do some regular roof maintenance and the occasional reapplication from time to time.

If durability is a real issue for you, for example if your RV is stored outdoors in harsh weather conditions, then we recommend paying extra for a highly durable silicone RV roof coating, or one that comes with a specific warranty for five or ten years.

UV resistance

It’s important to ensure that your RV roof coating is highly UV-resistant. While it goes without saying that all roof coatings need to be UV-resistant, it pays to double-check. Overtime UV radiation can degrade your RV roof, causing it to crack and fade, leading to leaks, hence the importance of using a good quality product that is resistant to UV rays.

Water Repellency

All RV roof coatings have good degrees of water repellency. However, if your roof isn’t in the best of shape to start with, you could be faced with a few areas where water tends to pond.

If this occurs and you don’t have the time, knowledge, or inclination to sort it out now, then you’ll want to opt for a silicone or urethane roof coating, as ponding water can cause acrylic ones to peel off.

Types of RV Roof Coating

Wondering what are the differences between each type of RV roof coating? Here’s the lowdown on the main properties of each type.

Urethane Coating

Durable and hard-wearing, urethane RV roof coatings are more expensive than acrylic versions, yet cheaper than their silicone equivalents. They are also reflective and UV-resistant, with improved waterproofing properties over acrylics.

Note that urethane RV roof coatings tend to give off a strong odor throughout installation and they often require two coats.

Acrylic Coating

Generally the cheapest type of RV roof coating, acrylic coatings are also reflective, UV-resistant, and provide good leak protection. They tend to be a little less durable than other coatings, although as they are cheaper, you may find it more economical to pay less and replace more often.

On the downside, if you have any areas of ponding water, acrylic coatings are likely to peel in these areas, causing leaks. So, make sure your roof is in good shape before applying. Additionally, you may need to use a primer and occasionally fabric reinforcement with an acrylic roof coating.

Silicone Coating

Silicone RV roof coatings are the most expensive on a per-gallon basis, however, as they only require one coat and no primer, they can actually work out cheaper than other types on a per-project basis. Silicone roof coatings are highly resistant, reflective, able to withstand huge temperature fluctuations, as well as having excellent waterproof qualities. They also have the distinct advantage of remaining extremely flexible so they won’t crack or degrade.

On the downside, silicone can hold onto dirt more noticeably than other types of RV roof coatings, although your roof will look like new again after a quick hose down or a light shower.

Also, bear in mind that you can only recoat silicone with silicone as other materials will not stick to it.

Rubber Coating

If you have an EPDM or a TPO rubber roof, then it makes sense to use a rubber RV roof coating that is specifically designed for use with these roof types.

Note that you will often require a specific primer and that not all rubber roofs are compatible with all RV rubber roof coatings, so be sure to double-check suitability before applying.

Rubber RV roof coatings hold up well to ponding water. They are UV-resistant and highly durable, with a good range of temperature tolerances, as well as waterproofing your roof even before they are fully cured.

Liquid Coating

Liquid EPDM RV roof coating is very similar to your traditional EPDM makeup. Liquid rubber RV roof coatings are generally easy to apply and they coat your entire roof in one seamless, waterproof membrane.

Suitable for use with a variety of different roof types, only one coat is required, saving your time and money. They are also highly durable, can tolerate both high and low temperatures, UV-resistant, and waterproof on application.

Fiberglass Coating

A popular choice for many travel trailers, RV fiberglass roof coatings typically utilize acrylic fiberglass resins for extra flexibility. They stand up to all weather conditions and won’t crack or peel with the sun. As they’re able to contract and expand with your roof’s movement, fiberglass coatings provide a high quality durable finish

We hope this FAQ section proves helpful in your journey to find the best RV roof coating for your needs. Let’s get started!

What is an RV roof coating?

An RV roof coating is a protective layer that is applied to the roof of your recreational vehicle to enhance its durability and extend its lifespan. It acts as a barrier against the elements, preventing leaks, reducing heat absorption, and protecting the roof from UV rays.

Why do I need to coat my RV roof?

Coating your RV roof is essential for maintaining its integrity and preventing potential damage. Over time, exposure to the sun, rain, and other weather conditions can cause the roof to deteriorate. A roof coating provides an extra layer of protection that helps to prevent leaks, reduces the risk of cracks and damage, and increases the overall lifespan of your RV roof.

What are the benefits of using RV roof coatings?

Some key benefits of using RV roof coatings include:

  • Waterproofing: Coatings form a seamless and watertight barrier, preventing water intrusion and leaks.
  • UV protection: Coatings reflect sunlight, reducing heat absorption and minimizing the damage caused by UV rays.
  • Energy efficiency: Reflective coatings can help keep the interior of your RV cooler, reducing the need for excessive air conditioning.
  • Longevity: Coatings can extend the lifespan of your RV roof by protecting it from environmental factors such as sun, rain, and pollutants.

How often should I recoat my RV roof?

The frequency of recoating your RV roof depends on several factors, including the type of coating used, the climate you’re in, and the condition of your roof. As a general guideline, it’s recommended to inspect your roof annually and recoat it every three to five years. However, it’s always best to consult the manufacturer’s instructions for the specific coating product you’re using.

Can I apply an RV roof coating myself, or should I hire a professional?

While some RV owners choose to apply roof coatings themselves, it’s often recommended to hire a professional for optimal results. Professional roof coating services have the expertise and equipment to ensure proper application and thorough coverage. If you decide to do it yourself, make sure to carefully follow the manufacturer’s instructions and take necessary safety precautions.

How do I prepare my RV roof before applying the coating?

Before applying an RV roof coating, it’s crucial to clean and prepare the roof surface properly. This typically involves removing dirt, debris, and any loose or damaged material. Additionally, you may need to perform repairs or patch any areas with cracks or leaks. Consult the specific instructions provided by the coating manufacturer for the recommended preparation steps.

Can I apply a roof coating over my existing RV roof material?

In most cases, yes. RV roof coatings are designed to adhere to various roof materials, including EPDM rubber, TPO, fiberglass, and aluminum. However, it’s important to ensure that the existing roof material is clean, dry, and in good condition before applying the coating. Some coatings may require a primer or specific preparation steps for optimal adhesion.

How long does it take for an RV roof coating to dry and cure?

The drying and curing time of an RV roof coating can vary depending on factors such as temperature, humidity, and the specific product used. Typically, the drying time ranges from a few hours to a day, while the full curing process may take several days or longer. It’s crucial to allow sufficient drying and curing time before exposing the roof to water, rain, or extreme weather conditions.

Are RV roof coatings permanent?

RV roof coatings are not permanent solutions, as they will eventually degrade over time due to exposure to the elements. However, they can significantly extend the lifespan of your RV roof and provide protection for several years, depending on the quality of the coating and the environmental conditions it faces.

Can I walk on my RV roof after applying a coating?

It’s generally not recommended to walk on an RV roof after applying a coating, especially during the drying and curing process. The coating needs time to properly bond and harden. If you need to access the roof for maintenance or repairs, use caution and follow any specific instructions provided by the coating manufacturer to avoid damaging the coating.

Remember, it’s always advisable to consult the specific instructions and recommendations provided by the manufacturer of the RV roof coating you choose, as different products may have specific guidelines and requirements.

Final Thoughts

There are an ever increasing number of RV roof coatings available. To ensure you find the best RV roof coating for your motorhome, be sure to focus on your roof type, as well as ease of application and any other constraints such as coverage and cure times.

If you are looking for a premium version, the highly popular Proguard Liquid Roof is a great option. This product requires just one coat, saving you time, money and effort.

On the other hand, if you’d prefer a more reasonably priced, middle-of-the-road version with a rapid cure time, we suggest going for Heng’s Rubber Roof Coating. Alternatively, for a budget application with a long warranty, you can’t go wrong with Kool Seal’s Elastomeric RV Roof Coating.
