Best RV Roof Sealant Buying Guide
Things to Consider When Buying an RV Roof Sealant
There are a number of things to consider when you buy roof sealant. First, you need to look at the size of your RV roof repairs. This will help you choose between paint, caulk gun, and tape. It will also help you to calculate how much to buy. Also, bear in mind how good you are at applying these types of products. If you find caulk guns awkward, it’s probably best to use a different type. Lastly, look at the length of time you have to finish your RV roof repair. Some products are quicker than others due to more straightforward application or lack of preparation needed.
Benefits of Using RV Roof Sealants
There are many benefits to using roof sealants which make them well worth looking into to completing on your RV. They include:
1. Temperature Regulation
Keeping your RV cool is useful, not only in Summer but all year round. An RV sealant can really help with that plus, by not having to use your air conditioning all the time, it will save you a lot in power too. With a mobile home roof coating, the inner temperature of an RV remains far more level and consistent. The result is that owners don’t have to switch on the air con all the time and have it constantly cycling round and round. This is purely due to the better insulation that an RV roof sealant coating can produce.
2. Lowering the amount of energy used
Any RV owner knows how great recreational vehicles can be, but they also are acutely aware of the amount of energy that they use on even the shortest of journeys. Roof coatings can materially help reduce the amount of energy consumption an RV goes through. This not only helps to reduce the running costs of your RV, but it also is far better for the environment due to the reduced amount of emissions created. Again, this is down to the much improved insulation of the vehicle.
3. Reducing your roof’s wear and tear
Perhaps one of the best benefits of adding a liquid rubber roof coating to the top of your camper is that you can help your RV’s roof have a far longer shelf life. This is particularly true of an RV sealant that has a cooling effect too. This characteristic can help deflect sunlight and other weather elements so that your RV has a great deal less wear and tear on it as time goes on.
4. Protecting your RV’s structure
The best type of liquid rubber roof coating will help extend your RV’s shelf life by protecting the structure. By protecting your roof from the elements, a rubber roof sealant can stop water and heat from destroying certain parts of your roof through general wear and tear and the growth of mold or other nasties. Heat, in particular, can cause the metal structure of your RV to continually contract and expand depending on the weather, so a protective rubber roofing can reduce this from happening.
5. It makes for a more comfortable ride
The use of a rubber roof repair product can seal holes in your roof and stop water from coming into your RV. You’ll give yourself a far more comfortable ride. You are also helping keep the interior of your RV at a far more consistent temperature owing to that all important improved insulation. Both of these add up to a far more comfortable ride and a happier RV user. This is true in both cold and hot weather as the rubber roofing that you have installed is able to protect your RV against both types of temperature.
6. Reducing the amount it costs to run an RV
Running an RV, as previously mentioned, is not always the cheapest activity. However, by being conscientious about roof maintenance and repair, you will find that your overall maintenance costs start to decrease. This is due to all that extra protection that you have added to your RV that will mean you have far fewer repairs to take care of elsewhere, in addition to lowering those running costs.
Types Of RV Roof Coatings
There are a number of roof coatings or camper roof products that may suit your needs better than others. You’ll need to think about the type, size, and location of your RV before deciding which is best for you.
- Acrylic RV Roof Coatings
Acrylic RV coatings are a good option if you need a slightly cheaper solution to act as a stop-gap in between when you have the time and the money to spend on a full-on RV roof repair. That being said, they’ll still manage to reflect a high amount of damaging sunlight and offer excellent protection against rain, water damage, and leaks. They are fairly UV resistant forms of RV roof coatings too. Where they lack is that an acrylic roof sealant is not great against pounding water, which may not even be an issue for some RV owners anyway. Acrylic roof coatings do not last quite as long as other RV sealant types and also require a couple of coats, a primer, and fabric reinforcer. This is obviously an extra cost and more time-consuming.
- Urethane RV Roof Coating
This type of RV roof coating is more expensive than acrylic, though slightly cheaper than other types mentioned on this list. Urethane used for a mobile home roof coating is also more durable than acrylic and other types, plus are great to protect against impacts like falling branches and other small debris. If you take your car around built up areas or within areas with lots of traffic, a urethane RV roof coating is a good idea. Obviously, however, you have to weigh up whether the added cost of using a Urethane RV roof coating is worthwhile for you. Plus, other negative points include a strong, pungent smell during application as well as the fact that this type of RV sealant needs two coats thus increasing the amount of time required to apply it.
- Silicone RV Roof Coating
Silicone is the last type of RV roof coating. It is the most expensive of all types of roof repair, but it is often bought simply because the benefits can outweigh the costs. It only requires a single coating and doesn’t require you to clean and apply a primer. Sometimes the cost of applying it to the roof can be cheaper. It is such an effective RV roof sealant or RV roof coating because it is highly resistant to weather, wind, and rain degradation. Additionally, it is good at deflecting against the harm of pounding water plus it can stay extremely elastic over time. It won’t become brittle or crack nearly as easily as other forms of RV coating products. One downside to silicone coatings is that it gets dirty far more easily than with other types of RV roof sealants. Regular washes will make light work of this dirt, however. Silicone also can only be applied to another silicone product so once it has been applied, it can only be repaired with other silicone RV sealant products.
The Best RV Roof Sealant and Coating FAQ:
Q: What actually is RV roof sealant and how does it work?
A: A roof sealant can take the guise of a tape or a mix between a paint and a varnish coating. It works by making RVs waterproof by sealing up cracks and holes that may be forming on roofs or around air vents or air conditioning units. They adhere to an RV’s surface to create a solid coating and make it strong again. Plus, many products are formulated to protect against any further damage being caused to your vehicle by being resistant to impacts, UV rays, the sun, water, and wind. All these environmental elements can play havoc with your RV, so it’s a great idea to use a coating of RV sealant as soon as you see a crack or hole forming.
Q: How do I apply RV roof coating?
A: Applying an RV roof coating is far easier than many may originally think. Plus, the key applying any type of liquid rubber roof coating is in the preparation. You need to ensure that you clean the surface thoroughly before any new rubber roof sealant can be applied. Some RV sealant producers, like a Dicor lap sealant, may even provide a specialized RV roof cleaner to help in this step. Following cleaning the surface, it is best to also apply some denatured alcohol with a soft cloth.
One more step prior to applying a new RV rubber roof coating is to remove any old sealant that has come away from the roof of the RV.
From there, apply your chosen RV roof coating product with a caulking gun by running a bead of caulk over the part of the RV roof you need to repair. That’s all there is to it. If you are trying to repair a crack, you need far less RV sealant products than if you plan to coat the entire roof. Start with less at first as you can always apply more.
Q: How many coats do I need for an RV roof repair?
A: As briefly mentioned in listing the types of camper roof sealant above, the amount of coats that you need for an RV roof repair depends on the type of RV roof sealant that you use. Urethane and acrylic forms of RV sealant will need at least a couple of coats in addition to a primer. Any camper roof coating that you apply which is silicone based only ever needs a single coat and no primer.
If using a urethane RV roof coating or an acrylic RV roof sealant, remember it is better to apply to thinner coats of the product than it is to apply one thick coat of the product. That way your RV will reap all the benefits that an RV roof repair can provide your vehicle with.
Q: What are good roof sealant brands?
A: We rate brands such as EternaBond and Dicor. They have been known to produce highly capable RV sealants that will last for years after being applied to any surface or RV roof. Additionally, we also like Geocel, Heng’s and Beech Lane. They all produce various forms of liquid rubber or other types of camper roof sealant products that can be used to perform an RV roof repair. Some RV users prefer to use tape like products on their vehicles while others prefer products that are more like paint. All manufacturers mentioned here produce a version of these products that are suitable for use on an RV that will more than amply perform an excellent RV roof repair.
Our Top Pick
