What is one of the most routinely missed aspects of RV maintenance? I’d have to say that it’s taking care of your RV roof, in this article we will cover Best RV Roof Coating reviews and guides.
The RV roof is often exposed to the elements, and sometimes when seemingly small damage occurs, it can snowball into a much bigger problem down the line.
RVs typically have coatings, and when those coatings suffer damage, water can seep into the roof of your RV and cause expensive damage.
Fortunately, this damage is very preventable, which is why I’ve created this guide that’s complete with reviews so that you can protect your RV from roof issues.
RV Roof Coating Buying Guide
Before we get into more detailed product reviews, I think it can really help you to know what to look for in the best RV roof coating options.
It’s important to remember that these products are best used yearly so that you can have a good level of protection during the RVing season.
While some RVers believe that coating should be done fairly often, many only refresh their coating once every several years. In this buying guide, we will cover the different types as well as what are some good features of the best RV roof coating solutions.
Why This Product Is Needed for RVing?
One of the aspects of an RV that is most often neglected, in my opinion, is the roof.
What results from this neglect is often thousands of dollars of repair work in order to shore up leaks. Coating provides a layer of protection that blocks both water and ultraviolet light from the sun.
Additionally, for those that want to save on RV weight, a rubber coat like EPDM or TPO is designed to not weigh much at all, which is why many RVers prefer this to other materials.
EPDM And TPO
Ethylene Propylene Diene Monomer (EPDM) is a great rubber material that has becomes something of an industry-standard in the past decade or so.
One of its best features is its lesser need for maintenance; EPDM coated roofs really won’t need much work for the first 10 years or so. EPDM is particularly resilient when it’s exposed to water or UV.
Also known as Thermal Poly Olefin, TPO has a different material construction than EPDM.
As a rule, TPO coating has a higher degree of rigidity than EPDM and is also significantly shinier.
TPO doesn’t oxidize as easily as EPDM and uses less plastic in its construction.
Ease Of Application
For the most part, I always suggest buying a product that has a house paint-like consistency. This allows you to coat your roof with a few simple tools like a squeegee and a paint roller.
Also, when it’s easy to apply, you can ensure that the coating is smoother and more attractive.
Insulation And Heat Flux Reduction
When we’re out camping, the roofs of our RVs can get very hot. This is why a coating that has a good level of heat flux reduction and insulation is useful.
These coatings actively reduce the heat transfer between the coats so that your cabin isn’t blazingly hot on warmer days.
This is a very useful feature to have in an RV coating material because, in the long run, it can reduce your draw on the electricity needed to power your RV’s AC unit.
This varies from product to product, but cure time is the time it takes the coating to solidify and become road-ready. Some coatings can take as much as seven days while others can take less than two.
Typically, warmer weather will speed up the process of curing, which is why I always try to cure my RV roof on as clear and warm a day as possible.
5 Best RV Roof Coating Reviews
I really like Liquid Roof because it is made of liquid EPDM, which means that it will actively replace your EPDM roof coating.
Additionally, this product also only needs to be applied in a single layer; this is particularly impressive because there are several products, even some on this list that will require two or more coats for a good layer of protection.
Liquid Roof applies like paint; it’s very easy to get onto the surface of your RV. You can even use a squeegee to get a good layer of coverage.
Once covered, the product is guaranteed by the manufacturer to last for a full five years, which is very impressive for a product of this type. In fact, a single coat can cover a 42-foot RV with a 20-millimeter thick coating.
- Protection for a full five years is very impressive.
- A gallon of the solution will cover a 46 square foot roof.
- It’s super easy to apply.
- The product is made of liquid EPDM.
- Roof bubbles can take a bit of time to flatten out.
- This can be a bit of a nuclear option for spot repairs. If you need to repair small leaks, you can just use a tape product.
There’s a reason why this Liquid Roof product is the go-to product for a lot of RVers; it’s reliable, has a long protection life, and is really easy to apply and protect your RV. If you need a nice product that’ll protect your roof, give it a try.
If you’re in need of a good amount of overall coverage, then I recommend this product by Dicor. Their RPCRC1 can manage 125 square feet of roofing with a single gallon, though it’s important to note that two coats are required per job.
Also, if you have a TPO roof, then this product can coat it with no issues at all. The product will protect against sun damage to your roofing membrane and will provide a nice and sealed layer so that water doesn’t become a major issue.
Since this product has such a good level of coverage, I find that it works well for multilayer applications. You can really get a high degree of protection for your EPDM or TPO membranes, which will add life to your roof and even save you a lot of cash on costly roof repairs.
- You can use a single gallon to cover a lot of roofs.
- This will completely protect roofs from the damage of sun and weather.
- It’s pretty easy to apply; just use a paint roller.
- This product will even help manage micro-tears in the membrane.
- It can take a while to cure.
- It can be hard to remove from clothes if you get some on you.
Dicor has done a great job at providing a reliable product with their RPCRC1 coating. It has a good amount of coverage, can manage EPDM and TPO roof membranes, and will provide protection for years. It even has an easy-to-coat formulation.
Heng’s is known for its ability to provide a bubble-free coating of its rubber material. Its overall consistency is somewhat like house paint; and as a result, it goes on very easily onto the surface of your RV roof membrane. A single gallon of the product will provide two to three coats on a thirty-square-foot RV roof.
One of the best features of Heng’s is its ability to flex and contract with the needs of the roof. This means that this product will be able to withstand changes in the temperature with ease. Heng’s is also a product that has good bonding ability; simply put, it’s designed to have a high adhesion level when applied to rubber.
- It’s slightly thicker than house paint, which means it goes on easily.
- This product does a great job of adding a protective layer to your RV.
- It bonds very well to rubber.
- Compared to some other RV roof coating options, it is fairly inexpensive.
- This Heng’s product can take up to seven days to fully cure on your roof.
- Water residue can form on the surface of the coating.
Heng’s Rubber Roof Coating is a great option for someone looking for a good way to coat their roofing membrane without spending a lot of cash. It’s easy to apply and can flex with your roof in order to withstand a wide variety of RVing conditions.
Liquid Rubber’s EPDM roof coating is a good option that you can use on rubber, fiberglass, acrylic, or metal roofs. Since it’s comprised of liquid EPDM, this product does a great job at providing a nice and protective coat for the roof of your RV.
One of the aspects that I really liked about this roofing option is its one-coat operation; this frees up a lot of time because you can just squeegee on a layer and let it begin its curing process.
When it comes to long-term viability, this coating won’t chalk-like some other EPDM coatings after seven or eight years. It also has an amazing temperature range; not only can it protect in temperatures as low as -40, but it can withstand blazing temperatures well over 300 degrees Fahrenheit.
- It has a great protective temperature range.
- It’s a long-term solution for RV roof coating; it’ll outperform other coating materials like elastomeric and urethane.
- There’s only a need for a single coat, which can save on labor.
- The catalyst in the coating forces air to the surface, which helps prevent cracks and pockets inside of the coating.
- This product has a tendency to put out some fumes, so wear a protective mask when applying.
Liquid Rubber’s EPDM product is a great option for just about anyone. Personally, I loved how versatile it was and the fact that it only requires a single coat makes it very convenient to use on a roof coating job for your RV.
Dicor RP-IRC-1 is called “CoolCoat” because of its ability to reduce heat flux transfer in your RV. This means that in addition to its ability to protect your RV roofing from the elements like water and heat, this coating will also provide an insulating effect for your RV, which will save you money in the long run.
As a result of the insulation, this product can reduce the internal temperature of the RV by as much as 29 percent of the roof temperature.
This is done through microcells, which are inside the material of the coating. These microcells are nano-sized and have an internal vacuum that allows for a reduced heat transfer from surface to surface. I think that this would serve just about any RVer well, especially when it starts to get particularly hot.
- The reduced heat transfer is very useful.
- Damages caused by UV light and water are very effectively reduced with this product. It dries quickly.
- The consistency of the material can vary a bit.
This product uses some amazingly high-tech solutions in order to provide a good degree of functionality.
Keeping your RV cool is something that we all need to do and the unique heat flux reducing features of the Dicor RP-IRC-1 CoolCoat really make it stand out as a good product for most RVers.
Finding an optimal solution for your RV roofing is important because it’ll save you money in the long run. Each of the products that I reviewed in this guide will last you for years and provide some top-notch protection from both sun and water.
If I had to select a favorite out of the products that I’ve covered, I’d say that the Dicor RP-IRC-1 CoolCoat edges out the competition because of its excellent and high-tech heat flux reduction abilities. This product is also excellent for overall protection as well.
