Best RV Roof Coating and Sealants
RV roof coating and sealants are among the most essential and crucial products for your recreational vehicle’s maintenance, care, and life-span. An RV roof coating seals, weatherproof, and waterproofs the roofs of RVs, campers, trailer-homes, and such vehicles.
Long time RV owners lay testament to the fact that a well-cared, well maintained, and dependable roof eliminates three quarters of the hardships and costs associated with RVs’ durability.
RV roofs are usually made out of rubber, aluminum, or fiberglass. Rubber roofs are the most common, and they are what most RV roof coating products cater to specifically. Aluminum roofs are similar to rubber roofs in that they also require the same amount of care and attention, if not more. Fiberglass roofs are more resilient to weather, water, and cracks but cannot be left unattended year long.
Why do you need RV Coatings and Sealants?
RV roof coatings provide a layer of protection from the elements in nature, including dust, rain, winds, debris, leaves, twigs, snow, and harsh UV rays. An excellent, effective roof coating helps prevent cracks in the roof, prevents molds and leakages, and protects the base roof membrane against decay.
They are especially important along with the linings of pipes, windows, and air conditioning, where most leakages and cracks originate. RV roof coatings are also used to fix tears and cracks as a sealant. Roof repair work is mostly never complete without roof coatings, which seal and coat the roof against nature’s damage.
A recreational home is not an affordable investment for most people. Operating and living expenses are also hefty if not optimally managed. It should be vital that we protect and care for the individual parts of our home-on-wheels like the roof, and minimize the maintenance and the operating costs to provide the biggest bang-for-the-buck when camping living in recreational vehicles.
Obviously, for maintenance purposes, RV roof coatings are crucial for the ‘roof over our heads.’ Leakages, cracks, and moisture in the roof membrane can start as a slight discomfort but quickly make it almost impossible to live inside an RV. Moreover, energy costs often take the most significant chunk of the overall running expenses when living inside an RV.
Again, leakages and cracks in the roof or along the seams of protruding pipes and windows let the air conditioning escape from the insides of an RV, which drive up energy costs.
RV roof coatings (EPDM rubber or silicon) work as a weatherproofing, waterproofing sealant against potential cracks, tears, decay, and motorizing of the roof of an RV. They not only help make the roof durable and protected against degradation; they also help seal in the air-conditioning to prevent leakages and keep the energy consumption low.
In addition to this, urethane and silicone types RV roof coatings offer a high reflectivity, which protects against harsh UV rays and keep the RV roof from heating up in sunlight, which again pushes down energy costs. Acrylic type roof coatings are less expensive than silicone and urethane, but their best do provide minimal reflectivity.
Be sure to clean your roof first using a good RV Wash product.
11 Best RV Roof Coatings on the market
We have taken the challenge to research through the RV roof coating products most popular and critically acclaimed by a wide range of diverse RV users, to see how they stack up against water, dust, snow, high winds, and the general shifts in temperature all year round.
Below we have listed the products we think are the best when it comes to RV roof coating in terms of protection, water resistance, sealability, reflectivity, durability, and ease of applying.
1. Liquid Rubber RV Roof Coating
Liquid Rubber RV roof coating is a flexible, protective sealant that is relatively easy to apply and makes for an environmentally friendly roof coating. Meant for rubber roofs and aluminum roofs, in 3 relatively thick coats, it provides a resilient adhesive rubber-line thick coat on your roof, sealing in the cracks and protecting against sunlight, rain, dust, debris, and snow.
Liquid rubber RV roof coating works well for all conditions, but the application weather preparations must be followed at the application time. This should not be applied on a humid, rainy day.
Most users complain about it not sticking well in such conditions. Hence make sure the prepping conditions are right. Overall this product makes for a good, if not the best, roof coating, protective, strong thick layering, reflective, and flexible. You cannot help but like this product if applied the right way and in the right conditions.
2. Heng’s Rubber Roof Coating:
Probably one of the most critically approved and popular products on the Market for RV roof coating, Heng’s Rubber-based roof coating is easy to apply. It fills in the cracks and seals vents and air conditioning to a very high degree of satisfaction.
Many roof coatings tick these boxes but maybe not to this high degree of reliability as maybe Heng’s Rubber roof coating does.
The application process involves first having the roof of your RV cleaned as best as possible, most people prefer a car wash, but it can be done yourself with some effort. Then you have to let it dry out before cleaning it again with a degreaser like Simple Clean.
After that, you seal in all straight and squared edges with Eternabond Tape, mostly around the pipes, vents, air conditioning, antennas, and other protruding materials whose edges are prone to cracking and leakages.
Then all that’s left is applying the product with a standard roller and paint tray. After a single coat, you must let it dry out before applying the second and third coat. Hopefully, you should have chosen a sunny day because moisture during the application process affects the product’s drying.
3. KST White Reflective Roof Coating:
An acrylic-based elastomeric (flexible and stretchable) RV roof coating, KST White Roof Coating, provides a reliable weather-protected roof coating.
A somewhat less known product on the market, users have ranked it high in terms of durability and ease of use, and the white coat provides a reasonable degree of reflectivity, keeping cooling costs down.
4. Liquid Roof RV Roof Repair Liquid EPDM Coatings – 5 Gallon Pail:
This EPDM RV roof coating is long-lasting, up to a decade if maintained, reflective of UV rays and ozone, and can be applied over all roofing materials except asphalt (understandable!) and Alpha rubber.
Epdm and alpha rubber are incompatible together; hence the Proflex flexible primer should be applied before the Liquid Roof Coating. Moreover, only one coat is required for the complete application.
The thing to keep in mind for this RV roof coating product is that when applying, one needs to make sure the weather conditions and instructions are followed. Some users complain that the product dries too quickly when using, so sometimes, half of the roof may begin to dry while you have not finished applying to the other half.
The trick to this is to set up in advance, read all the instructions before starting, have all the tools ready and at hand, and of course, checking the weather app before starting to work. Most users have found it worth the slightly higher price.
5. Proguard F99911 Liquid Roof Gallon
Another underrated yet vital RV roof coating product on the market is pro guard F99911 Liquid Roof. This EPDM-based liquid roof coating comes with a 5-year warranty and requires only one coating.
However, it will not work if applied to Alpha rubber roofs, as it says in the instructions. It also requires the Proflex flexible primer before it can be applied.
Many users have tested this product, and none have complained of any weaknesses in the adhesive quality and resilient nature of the Proguard F99911 Liquid Roof Coating.
Another decisive factor about these EPDM rubber RV roof coatings and mainly this one is that they withstand high and low temperatures and contract and expand with the RV’s roof.
This is very helpful in preventing cracks and tears in all sorts of climates and weather conditions. Our only second thought to this product is the demanding application process, which can get slow and tiresome, as some users have complained. However, in the long run, it seems to be worth it.
6. Dicor Fiberglass RV Roof Coating
This coating works to protect and beautify fiberglass as well as RV roofs that were previously coated. However, it is advised that this coating should not be used for EPDM Rubber or TPO Roofing.
The Dicor Fiberglass RV Roof Coating, made with 100% acrylic fiberglass resins, is flexible and fitting. It will expand and contract with the roof’s movement.
The RV roof coating is available in two colors: gloss white and gloss white tan. According to reviews, it bonds well to the roof, especially after two coats.
These light colors are reflective and will help you maintain low interior temperatures. The dry film coating helps resist mildew and algae, making it suitable for various weather where it will protect your roof.
7. Jetcoat White Reflective Roof Coating
It is a top-rated RV roof coating product among those who have tried it. Jetcoat Cool King provides an acrylic type elastic coating to an RV’s roof, which is reflective, seals cracks and tears, and protects the roof membrane against the harsh elements.
Users are initially concerned that the consistency of this liquid is relatively runny compared to others. As the manufacturers say, two coatings are necessary, and the third one is highly recommended.
This should be applied on a day when the temperature is above 60 degrees Fahrenheit. It takes about 3 hours to dry, but wait another couple of hours after drying before applying the second coating.
8. Ziollo RV Flex Repair Tape | White | 4-inch x 50 Foot Roll | Seal and Waterproof Roofs | Bond to EPDM Rubber with Butyl Sealant | Seam | Vent | Skylight | Flashing | Motorhome | Trailer | Camper |
The Ziollo RV Flex Repair tape can be used for sealing and waterproofing RV roofs. It has a butyl sealant of Teflon, making it an excellent option to stick to any surface that is not silicone-based. It bonds very well with EPDM and rubber surfaces.
This RV roof tape also works well with Caulking sealants. This Repair tape comes with a Seam Roller, which makes the butyl adhesive stick firmly on the surfaces and takes care of any bubbles or air gaps.
The adhesive layer is tricky to use in warm temperatures. Putting the tape in the refrigerator before using it works well. The adhesive side needs to be exposed by peeling off the plastic covering, but it isn’t easy to do in warmer temperatures.
Hence, if the tape is cooled before using, it works without a lot of effort. It would be best if you cooled it before using it, but not freeze it. Once applied, the tape stands well against direct sunlight and does not peel off.
The RV roof coating tape material also remains flexible and non-stiff in cold weather. Apart from being tricky to work with, this Roof tape does its job entirely to repair any damages or cover any seams that may be leaking—making it reliable for roof protection.
9. Kohree UV & Weatherproof Sealant Roofing Tape for RV Repair
The Kohree RV Sealant Tape is a Roof seal tape used for RV repairing, window sealing, camper roof leaks, etc. It works great in all weather. The UV technology makes it resistant to temperature changes and also protects it from direct sunlight. The firm and sticky adhesive acts as a self-priming seal.
This RV roof coating tape protects against moisture, toxic chemicals, and water or air leakages of any sort. The Roof tape works well with many kinds of materials, such as metal, EPDM, PVC, TPO, and rubber roofs. The process is straightforward and easy.
The non-sticky paper edges ensure that the tape does not stick with the covering it arrives in. Another benefit of using Kohree RV Sealant Tape is that its adhesion will increase over time, making it last for years. One can paint over this roof tape and caulk it for sealing it completely.
10. EternaBond RSW-4-50 Roof Sealant Tape
The EternaBond RSW-4-50 RoofSeal tape comes in three variants: 2″, 4″ and 6″ widths, and all are 50 feet long. The RV roof coating tape is 35mm in thickness. This adhesive is considered one of the stickiest available in the market, making it stand out from an array of products.
The UV protection allows the roof tape to withstand sunny weather and hot temperatures. It works on all kinds of surface material, be it rubber, metal, TPO, EPDM, or any surface. The sealant adhesive comes with a built-in primer and synthetic resins, making it sustain any water damage.
The easy application of this roof tape makes it perfect for repairing any damages or leakages. Another fantastic feature of this Roof seal is that it can easily sustain weather changes because of its elongation factor, making it an all-rounder roof maintenance and coating product.
11. Camp’N – RV Roof Tape – 4″ x 50′ – Weatherproof Patch/Repair/Seal for Rubber and EPDM Roofs
This RV roof coating product has a fair amount of adhesive, which becomes apparent when the plastic back is peeled off. The application process is straightforward, but the adhesive might stick to the protective coating hands in warm temperatures.
It works well for rubber and EPDM roofs and can also be used on metal roofs. The white coating may peel off in some cases, but the adhesive still protects from the water leaks. I
t is an affordable roof sealant that works on a variety of materials. The temperature range for this tape sealant is not wide, but it will prevent water and air leaks in the roof.
