Keeping your RV in tiptop shape is just as important as buying the right RV for you. One of the things that an RV owner should maintain is its roofing.  As such, rubber roofs are often preferred over those made in aluminum and fiberglass because they are lightweight and cheap.  Whatever you decide, you’ll want to make sure you get the best RV roof coating.

You must realize, however, that the initial layer on RV roofs will wear off over time, which is normal. And regardless of your roofing material, giving it a liquid coating is a must.

Summary

The positives: excellent coverage, waterproof, versatility, UV resistance, ability to prevent cracks, environment-friendliness, hassle-free usage

This is our top choice for a number of reasons.  While you can do just a single application, Heng’s Rubber Roof Coating covers the roof surface more evenly after two coats.  It comes with a bubble-free formula that will give your roof a flawless finish just like a good paint job.  This is why it applies easily to the RV rubber roofing.

The Heng’s Rubber Roof Coating also doubles as a sealant for your rubber roofs, seams, and tears.  What’s more is that it can even seal your AC unit and vent.  You can take advantage of its capacity of 1 gallon at an affordable price.  As such, it can provide full roof coverage for a camper that is 25 feet long.

This coat binds nicely to a rubber roof.  When you need to clean it up after application, it does quite easily.  As soon as it’s been fully dried and cured, its outer durability is very impressive.

Its UV-resistant quality will make sure you are protected from radiation and heat transfer.  It is also comforting to know that it is made of non-toxic chemicals and will not pollute the environment.

A good coating will allow flexibility and adjust to the movements of your RV roof.  Such is another strong feature of this roof coating.  Your Heng-coated roof will be able to withstand not only the sunniest climate but also inclement weather.

  • What other consumers liked about Heng’s Rubber Roof Coating
  • Excellent quality – Some attest to the roof coating’s longevity even for RVs that are used in warm climates. The product holds up even after a year from its application.
  • Economical value – As it is, it is very affordable at about $50. And for that cost which is equivalent to a gallon of this coat is enough to cover an RV that is over 20 feet in length.
  • Waterproof feature – This coat being waterproof, it will help maintain the integrity of your RV roof and keep it leak-free for many years.
  • Stickability – Even without a primer, the coat still gives good coverage and adheres to the roof surface nicely.
  • Areas for improvement:
  • Curing of the coat may take up to a week.
  • The product has thin viscosity, like latex paint.

Summary

The positives: wider coverage, use of liquid EPDM, cured membrane, seals leaks, cleans easily, waterproof, versatility, UV and ozone resistance

Not necessarily the second next best thing and more like being alongside the top spot, this coating promises to exceed your coverage expectations.  Liquid Roof is actually the name of the company which is a highly reputable provider and counts this as one of their best in their quality roster.

This roof coating is quite impressive with its ease of application.  Its one-gallon tub goes a long way with broad coverage of up to 46 feet.  That’s because all you need is just one coat and your roof will be protected.

Liquid Roof RV Roof Coating and Repair uses a liquid EPDM which has a superior ability to resist heat up to 300 degrees Fahrenheit and cold of -40 degrees Fahrenheit. This is also responsible for providing a barrier to UV rays and ozone.

The membrane, which is chemically cured, results in a vibrant color finish that lasts.  Any old, dilapidated roof can look like what it once was, if not even better when you use this coating.

This product is also known for its long-lasting effect aside from its aesthetic qualities.  You will not need another coating for the next three years or so.  You can also count on this roof coat to fix any leaks so you don’t have to buy a sealant for that purpose.

  • What other consumers liked about Liquid Roof RV Roof Coating and Repair
  • Highly effective in preventing leaks – There are those who have used this product on their RV roofs and are ecstatic to share that they have not had recurring leak problems anymore compared to when they were using other coating brands.
  • Sticks on the surface very well – The efficiency of this coating does not stop at its single application.  This liquid roof coat grips the surface like a magnet even with old caulking and seals it tight.
  • Magically transforms an old roof into a new one – The amazing part is that even after more than a year from its coating, the roof still looks vibrant and fresh.
  • Cleans without hassle – Maintaining the roof does not require much fuss as you can easily clean it with water using a hose or a pressure washer.
  • Areas for improvement:
  • The messy application can be tough.
  • A bit more expensive than other good brands.

Summary

The positives: specialized for rubber roof, coats up to 125 square feet, good ready-to-use packaging, uncomplicated use, provides excellent protection, UV proof

This Dicor product is easily one of the most sought after when it comes to providing weather protection for your RV roof.  For one, it is catered specifically for rubber roofs and it does a great job at it.

You must know that it is an acrylic coat which offers good and lasting performance. It leaves no room for moisture buildup as it seals your roof against it.  Amazingly, it can cover a good 125 square feet using just one gallon.

Like the other top 2 brands, the Dicor RPCRC1 can be easily applied on the roof surface using a roller or brush.  You will need to coat twice to get the best results.  This way, your roof membrane will have improved longevity.

You will also benefit from its elastomeric layer that will give your roof excellent protection. This product is formulated with a primer which preps your roof as demonstrated with the first coat.

The acrylic component will then reinforce your roof barrier.  In effect, your roof will not require any recoating for the next three years at least.

  • What other consumers liked about Dicor RPCRC1 White EPDM Rubber Roof Coating
  • Impressive coverage –  Buyers of this product are happy that they are able to stretch its use with more surface area, but without compromising the quality when it’s done.
  • Smooth application –  Applying this coat on your RV was not difficult.  And it creates a beautiful finish afterward.
  • Areas for improvement:
  • The cost is a bit high compared to Heng’s Rubber Roof Coating.
  • Drying time takes quite longer than usual.

Summary

The positives:  value for money, all-weather, high sticking ability, 90% UV reflective, durable, quick cleaning

If you are looking for a roof coat in the elastomeric category, then this variant is for you.  It gives a thicker coat than EPDM and offers decent protection on your roof that can last long.

With this barrier, moisture will not penetrate your interiors and chances of leaks are close to none.  This is bolstered by its near 100% UV reflective properties. All these contribute to a generous protective barrier of this product.

Another good feature of the KST063600-16 coating is its stickiness no matter what season you’re in. You don’t have to wait for a warmer climate anymore just to do the coating task.  Curing improves its resistance to mildew and mold.

The material composition of this coat is nontoxic, hence it will not harm the environment.  And characteristic of a good brand of roof coating, it adjusts to the expansion of your roof surface caused by heat and its contraction due to cold temperatures.

Best of all, it is very affordable.  Short of $150, you can get 5 gallons of lush coat for your RV roof.

  • Pros
  • value for money
  • all-weather
  • high sticking ability

Summary

The positives: versatile, multi-purpose, comes in bigger tubs, prolongs roof lifespan, beautiful finish, UV reflective, single coat, seals leaks

This is a considerable choice when looking for a reliable coat for your RV roof.  Its bigger 5-gallon size can accommodate more surface area and coating jobs.  For every gallon of this variant, you can cover up to 42 square feet.

The single coat application allows you to do more with the product.  You can use it to seal any leaks without buying a separate sealant.  It’s not only suitable for roofs on RVs.  You may also use it for trailers and mobile homes.

You will get more life from your roof with its stable protective barrier that allows it to withstand varying temperatures, reflecting heat whenever the sun’s out.

What amazes the most in this liquid roof variant is how your roof turns out after curing it.  The sleek finish is very impressive.  And the best thing about it is not having to prep your roof with a primer prior to application.

Aside from the fact that you are only applying one coat, it dries fast which can be both a good and a bad thing.  Looking at its benefit, your roof will practically be ready in no time.  And this roof will look very sturdy as well.

  • versatile
  • multi-purpose
  • comes in bigger tubs
  • prolongs roof lifespan

The 7 Best RV Roof Coatings: Weatherproof Your RV For Less

Keeping your RV in tiptop shape is just as important as buying the right RV for you. One of the things that an RV owner should maintain is its roofing.  As such, rubber roofs are often preferred over those made in aluminum and fiberglass because they are lightweight and cheap.  Whatever you decide, you’ll want to make sure you get the best RV roof coating.

An RV roof coating will give your roof a nice sheen and shield it from harmful ultraviolet rays and other harsh elements. It becomes a protective barrier, which will prolong the lifespan of your RV, making it more durable even with frequent use.

However, going to the store to buy one can be daunting, especially if you don’t know what you should be looking for in the first place.  It is important to determine which qualities must be taken into consideration before grabbing the first tub that you see.

What you need to know

I have come up with the following tips that could help you ensure that you are buying the right coating for your RV roof.

Check what your RV roof is made of

Does your RV have a rubber roof or a fiberglass one?  Knowing your roof material is the deciding factor in choosing the appropriate liquid coating.

Roof coating composed of TPO (or Thermoplastic Polyolefin) or EPDM (Ethylene Propylene Diene Terpolymer) is suitable for rubber roofs.  Then there are liquid coatings that are formulated with polyester to cater to other types of roofing like fiberglass as well as aluminum.

Fiberglass roof is heavier just like an aluminum roof, but more expensive. Both types, however, require low maintenance compared to rubber roofing.

Check the roof coating’s DIY factor

When you see the liquid coating in the store, which resembles a paint coating, you’d want the same application process as well.  In other words, you can apply it like you’re just painting over a surface.

So you will be looking for a roof coating that can be applied using an extended brush, squeegee, or a roller.  Sometimes just like with regular paint, a primer will be required for a smoother finish.  Ultimately, you should be able to do the task yourself and it’s important that it should be an easy application.

Check the insulation and reduction of thermal flux features on your roof coating

As you know, RVs are often exposed to the sun’s rays especially during summer.  It is best if your roof coat provides additional insulation and can also reduce heat flow from roof to ceiling.  This will make your stay inside as cool and comfortable as possible.

Another benefit of this feature will be on your AC’s efficiency.  When you get extra insulation from your liquid coating,  your AC will not have to work extra hard to cool the cabin.  This will mean savings on electricity or gas depending on your AC’s power source.

Check how fast the coating will cure

Curing is critical.  When your RV roof has observed the proper curing time, you will have a good, solid coating that’s ready to rock and roll. You definitely don’t want to mess this up.

Essentially, cure times will vary among different brands and types of liquid coating, which will range from 2 days to as long as 7 days.  You must note that weather can be a factor, too.

Summer is a good time to apply a roof coat because it can dry much faster compared to any other season.  You will be left with a shiny and beautiful coating that will last longer.

After reading all there is that you need to know about RV roof coating, it’s time to check out the brands you can choose from.    There’s just too many in the market so I have narrowed it down for you with only the best.  Let’s get right into it.

You must realize, however, that the initial layer on RV roofs will wear off over time, which is normal. And regardless of your roofing material, giving it a liquid coating is a must.

Other roof maintenance tips for your RV

For you to get the most out of your RV, create a habit of inspecting your RV especially before storing it in your garage or embarking on a road trip.  Aside from giving it a fresh coat, regular checks on the roof, in particular, are necessary so problems, if any, can be caught in their early stages.

  1. Get a visual of your RV roof surface by using a ladder instead of just climbing on top of it so that you’ll be able to hose any dirt off.  This is because it can be slippery as the roof material can’t support any considerable weight above it.  Cleaning the roof surface should be done at least every 3 months, or more if your RV is always parked under a tree.
  2. Before anything, don’t forget to refer to your RV manual to determine the cleaning procedure recommended for your roof.  It is not uncommon to stay away from the harsher chemicals like those that contain citric acids, abrasives, and solvents, which cannot be used on rubber surfaces.  Once you have picked the right cleaning agent, scrub using a sponge or soft brush and rinse off until no trace of cleaner can be found.
  3. Give your roof a careful scan for any cracks, punctures and any sign of deterioration and seal them right away.  Doing this will keep moisture away from your RV, which otherwise can bring mold and mildew that can be health hazards as well.

Conclusion

I hope you have learned a lot from the above for you to make an informed decision.  Ultimately, any RV owner will like to enjoy their vehicle for a long time, making many memorable trips in the process. So never take your roof maintenance for granted to make this possible.  Go and pick out the right roof coat for your RV.
