Liquid EPDM Roof Repair: The Best Kept Secret for RV Owners

Your RV is a source of liberty and adventure. You can go almost anywhere in comfort and style, and you’re never at a loss for things to do and places to see – whether you’ve got your trusty pop-up camper trailing behind you or you’re driving down the road in a luxury RV that would leave a rock band on tour with green-eyed jealousy.
But owning an RV of any type isn’t all Guns ‘n’ Roses. Even the smallest camper is a major investment – and if your RV suffers damage from something like a leaky roof, it can lead to a serious headache if you don’t catch it right away. Sure, you can get your RV repaired at the dealership if water gets into the subfloor, but it’s going to put your vehicle out of commission for weeks. It will also cost you a bundle. Happily, there’s a fantastic, low-cost option to keep your RV roof sealed watertight at all times. It’s called a liquid EPDM RV roof repair solution, and it’s the best-kept secret of all the savviest RV owners.

What in the World Is It?

EPDM, or ethylene propylene diene monomer, is a synthetic rubber that comes in both solid preformed sheets or in liquid form, stored in buckets similar to paint cans. While solid EPDM rubber is a great choice for commercial roofing projects, liquid EPDM is an amazing choice for smaller jobs – like patching the roof of an RV. Whether it’s liquid or solid, EPDM has incredible properties – it waterproofs the moment you apply it, even if you’re painting it on your RV roof – and it’s so durable and puncture-resistant that you might not have to replace your liquid EPDM coating for as long as ten years. Think that’s impressive? Solid EPDM sheets fitted to commercial buildings are capable of lasting half a century under the right conditions!

Never Worry About Your RV Roof Again

One coating – that’s all it takes. You don’t even have to set down a primer in most cases, as you can simply start with a clean, dry RV roof and apply it like you would with paint, and you’re sealed. The process will probably take you around 2 hours or less unless you’ve got one of those world-class 45 foot long RVs, and you can expect to use anywhere from 3 to 8 gallons depending on the size of your RV or trailer. On top of that, your RV will look better than ever thanks to its super-smooth coating. At this point, the only thing you’ll need to worry about is if you hit a low-hanging branch or two while you’re out on the road. There’s a good chance your liquid EPDM coating came through just fine, but take a quick look the next chance you have to make sure you don’t have to re-apply a few square feet to repair any damage done.

Use Liquid Roof RV Repair Products to Fix Leaks

It’s a scenario no RV owner wants to think about. They’re on the road or they’ve retired for the night when the rain begins. First, they hear the sound of each drop hitting the roof. Then they hear another sound. It’s drops of rain hitting the inside of their vehicle. A leak has formed somewhere and it will need to be addressed immediately or the rain will cause all kinds of problems. Obviously, rainwater could damage the inside of your RV, but it could also fry the electric system. This is why you should turn to a liquid roof RV repair product like EPDM.

What Is EPDM?

EPDM stands for ethylene propylene diene, with the M representing the type of monomer this rubber is. This liquid rubber has become extremely popular over the years, being used for RV roofs, commercial and residential roofs, plus more. Though it is often applied in liquid form, when EPDM dries (which can take a couple of minutes to a couple of hours), it becomes a very durable form of rubber.

Unmatched Durability

That’s the first reason many people prefer a liquid roof repair with EPDM coating for their RV. They definitely don’t want another leak happening and don’t want to risk any further problems. With EPDM, you can bet that the opening is shut for good and that no amount of damage from the elements will change that. This type of rubber has even been tested in temperatures from 40 below to 300 Fahrenheit and it survived. Therefore, chances are that any temperatures you run into shouldn’t be a problem either.

An Affordable Option

Another reason people love using this product is that it’s extremely affordable to purchase a good amount of EPDM. This liquid roof RV product can be purchased in single-use containers or you could buy enough to coat your entire roof.
If you’re worried about handing the job by yourself, you should know that applying a liquid roof to your RV really couldn’t be much easier. Still, there are plenty of professionals who can handle your EPDM liquid roof RV job as well. It still shouldn’t cost you much, though, because the liquid is cheap and it won’t take long, meaning labor should be cheap.

Long Lasting

Aside from just being durable, a liquid roof RV repair job done with EPDM is going to last for years. In fact, you can expect to get decades out of your application. This is why you may want to consider applying a liquid roof to your whole RV roof, not just the portion where a leak occurred. Do it now before you experience any problems and chances are you won’t have any in the future either.
The tight seal formed by EPDM will also mean that the inside of your vehicle will remain cooler when you have the A/C on and keep the sun’s heat out.
Whether it’s for a leak or some other type of damage, liquid roof repair with an EPDM coating is always a wise move. It’s also worth coating your vehicle’s roof now before problems ever occur.

How You Should Handle Your Next RV Roof Repair Job

A lot goes into making an RV road-worthy and comfortable. While it takes all kinds of different parts, it should go without saying that the roof is essential. Even the tiniest of leaks could become a big problem if you don’t quickly repair it with EPDM.

EPDM Is Long Lasting

The only thing worse than having to handle RV roof repair because of a pesky leak would be going to the trouble of fixing the problem only to have it happen again. Too many RV owners have had to go through this. They think the problem is history. Then they hit the road. As soon as it rains again, they realize they were mistaken and are now too far away to do anything about it.

You can rest assured that EPDM will take care of the leak once and for all. Chances are you’ll never have to handle an RV leaks repair job in that area ever again.

Simple Application

If you pay someone to take care of your RV roof repair needs, it can be still be pretty affordable if they use EPDM. That’s because this form of RV rubber roof repair is so easy to apply there will be minimal labor costs to cover.

This means that it’s also easy to handle on your own. You can find all kinds of EPDM products these days. Most just require you to spray them over the problem area. Then just wait for it to dry and you’re good to go. Larger leaks may need a version that is applied more like paint, but it still won’t require much time and you definitely don’t need prior experience using it.


Like we just touched on, EPDM is extremely affordable, even if someone else applies it for you. Depending on the size of your leak, you should be able to fix the problem and still have plenty of the rubber left over in case you ever need it again.

Little-to-No Maintenance

Just like you don’t want another leak springing up after you went to the trouble of fixing the first one, you also don’t want to spend hours of your life going forward making sure that your repairs will stick.

Fortunately, EPDM is extremely low maintenance. In fact, cleaning the area is basically all it takes to keep any recurring problems from being an issue. It doesn’t take much, though, so just hit the area like you normally would when you wash your RV and you should be fine.

Preempting Problems

If you want to make sure that needing an RV leaks repair job never becomes necessary, your best bet would be to use EPDM beforehand. Again, it’s extremely affordable, so you won’t have to break the bank to cover the roof of your RV with the material. This coating won’t just keep the rain out, though. It will also keep the sun’s rays at bay and your A/C inside where it belongs.

RV rubber roof repair is the way to go when you get a leak. Just be sure it’s EPDM and that you handle the job right away.

5 Must Know Tips for Successful RV Roof Repair Project

RV roofs are lightweight, durable and resistant to the elements, but that doesn’t mean they’re impenetrable. It actually takes surprisingly little to damage your RV’s roof. Strong winds might blow a branch down, punching through the roof and creating a serious leak. Over time, mold and mildew might compromise your roof’s integrity as well. RV roof repair can be tricky, particularly if you’re doing it yourself, but there are several tips that can make the process easier.

RV Roof Tip-1 : Find the Leak First

Your leak might be obvious. That branch sticking out the top of your RV? That’s the most likely culprit. However, it’s also possible that the source of the leak isn’t that obvious. If that’s the case, you’ll need to get up on top of the RV to inspect things. If your RV is older, chances are it has a metal roof. However, if it’s a newer model (manufactured within the last 10 years or so), it probably has an EPDM (rubber) roof. Don’t walk on metal roofs without first putting down supports – plywood slats work. EDPM roofs can be walked on with care.

RV Roof Tip-2 : Find the Defect

There’s a difference between RV leaks repair and just sealing leak temporarily. If there’s a defect causing the leak, such as a puncture, you’ll need to make an actual repair to the underlying structure of the roof. If the rubber coating over the roof is damaged, you can use RV rubber roof repair to seal it. If there’s a defect or damage, repair it first, then seal the damaged area with RV roof repair rubber.

RV Roof Tip-3 : Small Leaks

If you notice a very small water leak from your RV’s roof, you can handle it without too much trouble. These leaks generally involve nothing more than a minor problem with the rubber roof or one of the seals. In these instances, a couple of coats of RV rubber roof repair sealant will be all that’s necessary. However, before you do anything, make sure the leak really is minor.

RV Roof Tip-4 : A Note on Bubbling

It’s normal to see some bubbling on your RV’s roof. However, that doesn’t mean these are defects or flaws. Rather than trying to cut out the bubble, just repair the leak. Bubbles will usually go away on their own over time. In fact, it’s somewhat normal to see bubbles form in the rubber leak repair material itself. These will shrink and disappear shortly.

RV Roof Tip-5 : Buy the Right Products

As a final note, you should make sure you’re actually buying products made for RV roof repair. There are products designed for residential and commercial use that are similar, but you need to make sure that you’re purchasing rubber roof repair material designed for use with RVs. RVs uses EPDM roofing material, and it takes the right type of material to repair leaks here.

RV roof repair doesn’t have to be time consuming or difficult. A handy owner can usually tackle basic RV roof repair needs on their own. However, know when a problem is too big for you, and get professional help.

There’s no getting around the importance a roof plays in any structure. Whether it be a home, a warehouse, office building, etc. you need a strong roof that can provide shelter from the elements. Leaks do happen, however, at which point, you want to act fast to solve the problem. Despite all the options available, you can’t do much better than having EPDM roof coatings above your head. Keep reading to learn why applying EPDM to your roof is one of the best decisions you can make for the structure.

Immune to Most Climates:

EPDM roof coatings can handle just about any climate condition short of a tornado. They can withstand low temperatures all the way down to -40 F without cracking or becoming brittle.

If you live in the Southern Hemisphere, you’ll be glad to know that a roof covered in EPDM doesn’t mind the warmth, either. While temperatures will never get up to 300 F, EPDM has shown it wouldn’t be a problem if it did.

The really great thing about EPDM roof coatings, when it comes to climate, is how much it can save you in energy costs. EPDM gets a lot of credit for keeping the elements out, but the truth is that it does just as good a job keeping your cold air or heat in, where it belongs.

As the above attests, a roof covered in EPDM will have an easy time withstanding the elements. Yet EPDM needs very little, if any, maintenance. While you’ll want to clean your roof periodically, simply to keep things like fungi or algae from growing, the synthetic rubber itself won’t need any help.

This also provides greater savings. The longer you can go without having to fix your roof again, the more of a return you’re getting on your investment. But this can also provide great savings for use on an office building. As that type of building constantly undergoes inspections for worker safety, you won’t have to worry about spending more to keep it up to code.


It’s hard to think of another option that can provide the kind of longevity you’ll get from installing EPDM Roof coatings. The ERA (EPDM Roofing Association) recently conducted a study. In it, they examined a number of EPDM roof coatings that were 30 years old. Their finding was that, even after 3 decades, the EPDM maintained a high degree of tensile strength, almost as if it were new.
