Buy from Amazon

If you are having difficulty stopping a leak in your RV roof, you might want to try the Marine Fast Cure Adhesive Sealant by market leaders 3M. Designed to seal below the waterline on boats, this high-strength sealant permanently bonds aluminum, gelcoat, wood, and fiberglass.

Its highly flexible, durable elastomeric bonds provide a watertight seal, thanks to its gap-filling, moisture-curing polyurethane formula. As it is so flexible, it allows for joint movement, vibrations, and stress for a permanent bond. What’s more, it is also easy to apply, remaining workable for up to four hours after applying with a trowel or spatula. Plus, it won’t sag or flow in horizontal or vertical seams.

However, this ease of application also means a cure time of around 48 hours, although it does become tack-free within one to two hours. This sealant does stick exceptionally well, which justifies its fairly high price tag. While you should be able to fix small leaks with this three fluid ounce tube, you may want to invest in the larger 10 ounce version for more extensive roof renovations.

If you live in a very hot climate, or frequently travel to areas where you get a lot of sun, you may want to check out some of our other recommendations for RV roof sealants with extra UV protection. However, against the wet alone, you won’t find a harder-working sealant than this one.

Looking for an easy way to a professional RV roof seam finish? One that will keep water out of your coach for years to come? EternaBond Roof Sealant Tape is the ideal solution to repair and seal any tear or open seam on your RV’s roof. What’s more, it’s compatible with almost all motorhome roofing materials, including EPDM and TPO roofs.

Installation is extremely simple, with just a little surface preparation required before use. You can also use this sealant tape to seal around certain objects, for example, vents, as the tape also sticks to itself. However, curves can be fairly tricky to master, so you’re best starting off with straights. Also, once you’ve stuck it down, it’s very, very difficult to get it back up, so slow and steady is the rule!

Thanks to its MicroSealant Technology, consisting of synthetic resins, thermoplastics, and non-curing rubber, EternaBond Sealant Tape has a very high elongation factor. This not only ensures that your roof remains watertight, it also means that the seal is able to expand or contract depending on changing conditions for outstanding long-term performance.

Its UV-stable backing ensures that this roof sealant can stand up to sunny environments, while its built-in primer allows for maximum adhesion. At four inches wide and 50 feet long, this roll should be plenty to do your RV roof seams with a little leftover for any emergency situations.

While it is pretty expensive, this stuff can last for years and years, ensuring your coach remains protected. It also reduces the amount of time you’ll need to spend on RV roof seam maintenance, so much so that over 25 prestigious RV manufacturers are now using EternaBond products during their manufacturing process. Need we say more!

Trusted by RVers all over the country, the ever-popular Dicor’s three-stage roofing system is certainly tried and tested. This self-leveling Lap Sealant is the third part, providing a secure secondary seal wherever you need it on your RV roof.

Specially formulated for ¼” and ⅜” beads, use this sealant to keep water out of your coach. It seals roof edges, around air vents and pipes, as well as screw heads and seams. Fiberglass, galvanized metal, aluminum, vinyl, mortar, wood, and concrete, this sealant adheres to a wide range of materials.

While it is also compatible with EPDM and TPO sheeting, bear in mind that the packaging states that it may not be suitable for some TPO roofs, so double-check if this could potentially affect you.

This self-leveling formula is an excellent choice for a professional finish on your RV roof. Once applied, the sealant flattens out, which will allow water to flow across it, while securely sealing your exterior. This makes this RV roof sealant very easy to apply, a must if you have shaky hands or are just no good at caulking in general.

Another advantage of this particular RV roof sealant is that it remains flexible once applied, so you can be sure it won’t crack, even with joint movement. UV-stabilized to prevent discoloration and deterioration, you can rely on this product to keep your coach protected in all weather conditions.

Waterproof in four hours, 80% cured after 48, and fully cured after a month, this product is highly effective and available at a good price, making it well worth having a tube or two to hand.

All in all, a top RV roof sealant that is one of the easiest around to apply.

Best “No Caulk Gun” RV Roof Sealant

Premier Pro Products RV Roof Sealant

This Universal Roof Repair Sealant has been formulated by Premier Pro Products after over 30 years of hands-on experience in the roof repair industry. Made in the USA, this RV roof sealant comes in an innovative 25.3 fluid ounce pouch, making it easily resealable, unlike your average 10 fluid ounce tube.

Another advantage of this product is that you don’t need a caulk gun to use it. Getting a smooth bead out of the bag does take a bit of practice, however, you can use tape and wipe it over with a damp cloth for a smooth, neat finish. As it is easy to clean off before it tacks up, it’s a great choice if you are a little heavy-handed and have trouble with regular caulk that is often tricky to remove.

As this lap sealant is self-leveling, you get good results for very little effort. What’s more, as with all self-leveling products, you get a finish that water will flow over, rather than pooling. This universal sealant is suitable for rubber, metal, asphalt, and most roof types.

This RV sealant provides exceptional sag resistance. It also has some tough physical properties, boasting high tensile strength and excellent elongation – ideal for taking on the harsh exposure that your RV roof goes through.

With 130 linear feet coverage in one pack, it certainly goes a long way, and what you have left over can simply be resealed for future usage.

Highly versatile and available at an affordable price, Lexel Adhesive Caulk by Sashco makes a great buy. This copolymer rubber-based sealant is made in the USA and compatible with a wide range of materials, so you can use it to touch up other areas in addition to your RV roof.

While Lexel is suitable for use with most plastics, metals, and common building materials, including fiberglass, PVC, vinyl, aluminum, steel, glass, and plexiglass, among many, many more, unfortunately, it does not work at its best with rubber or silicone materials. In fact, if your RV roof has a rubber liner or a Kynar finish, it is recommended that you do not use this product.

Lexel is tough and extremely tear-resistant. However, it is also a soft rubber. This allows it to flex with your RV, being able to handle up to 400% joint movement. What’s more, it is also highly UV-resistant, so you won’t experience any yellowing or loss of protection due to sun exposure. It is also easy to paint and crack resistant.

Thanks to its high levels of elasticity, Lexel is also easy to apply. You can even apply it in any weather as it is instantly waterproof upon application and it won’t freeze. It even sticks to itself for recoating purposes, or if you decide you need a bit extra to fill out a deep seam.

Tough, elastic, and UV resistant, if you are looking for a sealant for your RV roof, as well as for applying around your RV, both inside and out, Lexel is a highly versatile, relatively low cost buy.

This 100% EPDM rubber roof has a five-year warranty, although it’s not uncommon to discover it’s still in excellent condition 10, or even 15, years down the line. It provides unparalleled protection for your RV and really gives your roof a seamless, professional-looking finish. You can even apply more a month after as being a rubber it adheres to itself.

As you would expect, getting your entire roof ready and finished is quite a bit of work. However, once you have cleaned and primed if necessary plus caulked, this product goes over like a coat of paint. Just be sure you have all your tape in place and are 100% ready to go before mixing the two parts thoroughly and getting started. It can get a bit messy and you’ll want some throwaway gloves, old clothes, and brushes.

This sealant waterproofs immediately on application, protecting your coach from water damage. It does, however, take 24 hours to develop a skin, so be sure to park up away from any trees or anywhere where you’re likely to get dirt falling on your new unset roof. After three days, you can walk on it, so it’s really pretty quick considering you’re getting a whole new roof coating.

Unlike your average caulk or silicone, this tape won’t crack, harden, or shrink, giving you a reliable, durable bond that will really hold for years to come. What’s more, as it’s a tape, you get instant waterproofing, with no waiting or cure times.

Buyer’s Guide to Buying the Best RV Roof Sealant

With so many different RV roof sealants to choose from, choosing the right one can be a little tricky. Here’s what you need to look out for when you’re buying a new RV roof sealant.


No one wants to pay over the odds. However, when it comes down to choosing a roof sealant for your RV, you’re better off spending a few extra dollars to get a high quality RV-specific sealant.

Not only will it save you money in the long term, as you won’t have to replace it as often, a tried and trusted RV roof sealant will better protect your coach and could potentially save you hundreds, or even thousands, of dollars in costly repairs caused by water damage.

Unless you are looking at adding a liquid rubber membrane, most RV sealants are priced fairly evenly. Expect to pay anywhere between 10-22 dollars for your average 10 fluid ounce tube. Tape comes in at a bit more, however, it can save you time on application, plus any unused part of the roll won’t go off and is very handy to have onboard in case of any damage.

Type of Roof Material

Perhaps the most important criteria, you need to be absolutely certain that your RV roof sealant is compatible with your roof type. If you don’t, it could fail to adhere correctly, wasting your time and money, or in the worst-case scenario, it could even damage your roof.


Rubber is the most common type of RV roof around. Lightweight and relatively cheap, it’s easy to see the advantages of using rubber for your motorhome’s roof. However, they do require regular maintenance.

Most RV rubber roofs are either EPDM or TPO roofs. You really need to know the exact specifics of your RV rubber roof before selecting an appropriate sealant. Always make sure that your sealant clearly states that it is suitable for use with your particular type of rubber roof. If you have any doubts, contact the manufacturer for further details.

As general roof and all-purpose sealants tend to be less suitable for EPDM and TPO roofs, it’s best to use an RV-specific version that is specially recommended for these materials.


Lightweight and strong, fiberglass is another popular RV roofing material. While fiberglass roofs are less common than rubber ones, they do have the advantage of requiring less maintenance. They are also compatible with the vast majority of RV roof sealants, so the stakes won’t be quite as high when you make your selection.


Less common again, metal roofs are more likely to be found on old-style RVs. Aluminum in particular, given its low weight and high resistance to the elements, is a proven favorite. It is also highly durable and requires little in the way of maintenance.

Elasticity & Tear Resistance

To withstand conditions out on the road, you’ll need a roof sealant that has plenty of elasticity. Unlike your bricks and mortar roof, RV roofs need to withstand vibrations, bumps in the road, and increased expansion and retraction of joints.

Elasticity alone is not enough, your RV roof sealant also needs to be tear resistant. This will ensure that your sealant, be it tape or caulk, has enough tensile strength to withstand the forces that are placed upon by various weather conditions as well as driving on the freeway and down uneven roads littered with potholes.


RV roofs tend to get a lot of sun, so it makes sense to opt for a sealant with UV-resistance. Not only will this protect against any ugly yellowing, it will also protect against your sealant during out and cracking, extending its lifespan and efficacy.

Ease of Application

Even if it’s the best RV sealant in the world, if it’s not easy to apply then you’re unlikely to finish its application.

While caulking, in general, can be a little tricky, most RV roof sealants in our selection are fairly easy to apply. Above all, you need to take your time and prepare your area carefully before applying.

Don’t try to do too much in one go. Sealants that remain flexible for some time afterward can generally withstand more corrections. While tape is a popular choice, you need to be very well prepared and focused for a smooth application.

If you don’t stick it correctly, then you won’t be able to start over again.

Reason for Getting a Sealant

You also need to match your RV roof sealant to your needs. Do you have an emergency leak that you need to stop right away? Are you doing annual maintenance? Or, are you looking for a just-in-case sealant for your next trip?

If you need to urgently stop a leak, you will be focusing on rapid delivery times and a rapid cure. For your annual maintenance, you will probably want a decent amount of RV sealant to go over any potential areas that could leak in the near future.

Just-in-case sealants can be pretty much any type, however, they need to be easy to apply when you’re out and about on the road. Tape is a popular choice or a caulk that tacks over pretty quickly.

Curing Time

The curing time is how long it will take for your sealant to completely set.

This can vary considerably from one manufacturer to another. Sometimes you may find that faster setting versions are priced higher, however, in a lot of cases your sealant will skin over within a few hours.

If you need to get your RV out on the road as soon as possible, then take a closer look at the curing times. If you are doing your annual maintenance and have a more relaxed schedule then this won’t really be much of an issue for you.

Some RV roof sealants can take several weeks to cure completely, although most are waterproof on application.

Types of RV Roof Sealant

There are several different types of RV roof sealant on the market. Find out which is best for your motorhome, skills, and needs, right here with our guide to the most popular RV roof sealant types.


Simply put, caulk is a waterproof filler that is used in repairs and maintenance.

Standard RV roof caulk comes in 10 fluid ounce tubes that need to be applied with a caulking gun. Just like caulking around your bathroom at home, you want to get a nice bead that will fill the gap that you need to seal.

While caulk is fairly easy to apply depending on how much practice you’ve had, it doesn’t tend to keep very well after use, so you may want to look at smaller or resealable versions if you only have a small area to treat.


Liquid EPDM RV roof sealants tend to be the most work to apply, requiring large amounts of preparation and extensive priming.

While most liquid RV roof sealants go on like paint, you still need to tape up your edges and prime your roof. They give you a seamless finish and excellent waterproofing. They can take a while to fully cure, however, after a month or so you can add another coat or do another part of your roof as the rubber adheres to itself.

This is a great way to improve the quality of a neglected RV roof. While Liquid RV roof sealants are relatively expensive compared to simple sealants for spot repairs, they do work out a lot cheaper than replacing the entire roof.

Also, their seamless finish and improved weather resistance will improve the looks of your RV and add value.


Tape sealants are another popular choice. They have no curing time and are fairly easy to apply, as long as you place them down correctly the first time over, as there won’t be a second time. They give you a neat seal with no cure time or cleaning up required afterward.


Mostly PU polymers, RV adhesive roof sealants are extremely tear-resistant. They provide exceptionally strong bonds, making them a good choice for resistant leak sites that other sealants have failed to adequately block.


Self-leveling RV roof sealants are a good choice for a neat finish, without having to do too much work.

This makes them easier and faster to apply, however, they are only suitable for horizontal application. As they self-level flat, they will give you a good finish that will prevent water from pooling, preventing any future issues from developing in that area.

So, let’s dive into the frequently asked questions about RV roof sealants and equip you with the knowledge to make informed decisions about protecting and maintaining your RV’s roof.

What is RV roof sealant, and why is it important?

RV roof sealant is a specialized product designed to protect and seal the roof of your RV. It creates a waterproof barrier that prevents leaks, protects against UV rays, and helps maintain the integrity of your RV’s roof. It is important because a properly sealed roof can prevent water damage, mold, and structural issues.

When should I apply RV roof sealant?

It is recommended to apply RV roof sealant at least once a year as part of regular RV maintenance. However, you should also check for signs of damage or wear, such as cracks, gaps, or peeling sealant, and address them immediately by reapplying the sealant.

What types of RV roof sealants are available?

There are several types of RV roof sealants available, including silicone, acrylic, and butyl rubber. Silicone sealants offer excellent waterproofing and UV protection, while acrylic sealants are more affordable and easier to work with. Butyl rubber sealants are known for their flexibility and durability.

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

Applying RV roof sealant can be a DIY project if you are comfortable working on your RV. However, if you’re unsure or have a complex roof structure, it may be best to consult a professional to ensure proper application and avoid potential issues.

What preparation is needed before applying RV roof sealant?

Before applying RV roof sealant, it is crucial to clean the roof thoroughly to remove dirt, debris, and old sealant. Use a suitable cleaner and a soft brush or sponge to scrub the surface gently. Allow the roof to dry completely before applying the sealant.

How long does RV roof sealant last?

The lifespan of RV roof sealant depends on various factors, such as the type of sealant, weather conditions, and maintenance. On average, a well-applied RV roof sealant can last anywhere from one to five years. Regular inspections and maintenance can help identify when reapplication is necessary.

Can I apply RV roof sealant over existing sealant?

In most cases, it is not recommended to apply new sealant directly over existing sealant. It’s crucial to remove any old or damaged sealant before applying a new layer. Failing to do so may result in poor adhesion and compromised waterproofing.

Are there any specific precautions I should take when applying RV roof sealant?

Yes, when applying RV roof sealant, it is essential to wear protective gloves and goggles to avoid skin and eye irritation. Follow the manufacturer’s instructions regarding application techniques, temperature requirements, and curing time. Work in a well-ventilated area and avoid applying sealant during rainy or excessively humid conditions.

Can I walk on the roof after applying RV roof sealant?

It is generally recommended to avoid walking on the roof after applying RV roof sealant, especially during the curing period. Walking on the sealant can disrupt its adhesion and affect its effectiveness. If access to the roof is necessary, use proper precautions and walk on support beams or boards to distribute your weight.

Where can I purchase RV roof sealant?

RV roof sealants are available at RV supply stores, camping stores, and online retailers. You can also check with your RV manufacturer or local service centers for recommended sealant brands and suppliers.

Remember, while this FAQ section provides general information, it’s essential to consult the specific instructions provided by the manufacturer of your chosen RV roof sealant for the best results.
