One of the best things about an RV is the fact that it provides you with a home away from home when you feel the need to travel. It gives you a solid roof over your head, and certainly one you don’t want to take for granted. This is why it’s very important to give your RV roof the proper care it requires, including using the best RV roof sealant to ensure it is watertight.

Water damage from a leaking roof doesn’t just cost you hundreds, if not thousands of dollars. It can also severely damage your RV beyond repair, not to mention damaging your valuable possessions inside of it.

Choosing an RV Roof Sealant: What to Take Into Consideration

Here’s the thing: all RVs are different, so there isn’t a ‘one size fits all’ solution when it comes to roof sealant for your RV. These are the important aspects you first need to take into consideration to determine which RV roof sealant is for you:

The level of damage: Why does your RV’s roof need sealing? Is there a small leak that needs a quick and easy application of sealant, or full-blown damage over the years requiring a complete roof re-seal? Depending on your needs, your required product will vary.

The roof material: Many RV roof sealants are also targeted towards specific roof materials, such as rubber, fiberglass, or aluminum. Keep in mind that there are also two different types of rubber roof, including EPDM (Ethylene Propylene Diene Monomer) and TPO (Thermal Poly Olefin).

The level of elasticity or tear resistance required: This will vary between liquid RV roof sealants and tape sealants. According to Car Care Total, “You need to use the right materials in the right spots. A very rubbery sealant is ideal for joints that expand and contract, while a stronger or rigid sealant is great for areas that have to support some weight.”

Resistance to UV: Like many parts of your RV, your roof can also wear down over time from being exposed to harmful UV rays. Not only can you select RV roof sealing that is UV resistant, but you should also further protect your RV’s roof with a cover.

How to Seal an RV Roof
