Leak-free RV roof
Getting RV roof repairs is expensive especially if the problem isn’t small. When it comes to leaks, preventing it is better than stopping it when already there. You should get an RV roof sealant if you want to protect your RV roof from leaks.
UV resistance and reflectivity
Most of the best products have high UV resistance, so they resist discoloration and deterioration. Some of them also have high UV reflectivity, a measure of the specific heat and light amount reflected away from the RV roof.

How We Picked
We understand the difficulty of looking for the right RV roof sealant. There are many kinds of these products; each can be used for different situations to achieve a specific desired result. That is why we’ve made a list of considerations when comparing and reviewing each sealant we’re reviewed in this guide.
The application reason
One of the first things to consider when shopping around for an RV roof caulking or sealing product is its ability to seal the application reason or purpose you have. It is the same reason you have to determine the application purpose before buying one.
If you just also need to fix a small leak, buying a tube sealant might just be what you need. On the other hand, you might need a larger variety if you need to do a huge repair on your roof that has degrade over time and needing recoating.
For this reason, you should also figure out the level of degradation your roof has before buying a roof sealant.
The roofing material
Know the exact roofing material you have to determine the right kind of product top buy. The most common roofing material is rubber. It is what most recreational vehicles have because it is cheap and lightweight. You should pick a sealant to work well and stick on this surface for the best-desired effects. Shop around for roof sealants that can work effectively on rubber roofing materials.
Another kind is Ethylene Propylene Diene Monomer (EPDM), which requires no extra UV protection; however, it needs recoating from time to time. You should take note of that.
On the other hand is the Thermal Poly Olefin (TPO) roofing material, which is sturdier than EPDM as well as shinier than the other types of roofing materials.
We also considered elasticity when comparing the products we’ve featured in this guide. It is the product’s ability of twisting or turning and expanding or contracting without losing the protection that it provides the RV roof with. On the other hand, tear resistance refers to the strength of the product when it comes to the amount of force it can deal with before it breaks up.
Elasticity applies to both types of RV roof sealants – the tapes and the liquid sealants. Liquid sealants might need bit flexibility for the changes. For tape sealants, look for those difficult to tear and have a high flexibility.
Ease of application
You shouldn’t buy a roof sealant that requires much effort and time to install. In addition, you might want to avoid varieties requiring an activator or a primer that you probably don’t have with you. That is why you have to check carefully before buying. Buy one that is easy to use and clean up in the case of mistakes in application.
