Things to Consider When Buying RV Roof Sealant
Whether you're vacationing in your RV or living in it, roof cracks can be a major hindrance in the quality of the living space. If it's raining a crack can cause major issues for the inside of the RV space such as mold, grime, and ruined electronics.
Checking product specifications should be step one before buying any RV roof sealant. This will save you time, money, and help avoid unnecessary complications. We'll dive into some of the specifics to check on right now.
One specification to be aware of is the material used in making the sealant.
The material is an important component for numerous reasons because it affects the durability, longevity, and your ability to use the sealant effectively.
The material of the sealant, and the material of the RV roof or spot to be patched up should be taken into consideration. Common materials are typically EPDM or TPO rubbers.
EPDM rubbers are typically black, very durable, and can last up to a decade. So when maintenance is necessary on EPDM roof, you want to do it right. We'll mention which products go with EPDM in the product review section.
TPO roofing tends to be shiny and rigid and don’t last quite as long as EPDM, but with proper care and maintenance they can last as long as you need.
We will also be mentioning which sealants work best with the TPO material as well.
Another thing to consider before buying is how to apply the RV roof sealant. Application can pose complications if not careful with your choice. The different types of application processes include brushing on, squeezing from a tube, and sealant tape.
The process you choose should depend on the size of the RV crack. If it’s a really small slit in the roofing, a squeeze tube should get the job done. Roof sealant tape is one of the more convenient options and can easily be expanded or contracted for changing crack conditions.
Are all Roof Sealants the Same?
As mentioned earlier, not all roof sealants are the same. The material, longevity, ease of application, and durability of the RV roof sealants can vary widely. So be sure to check out the details of each sealant first.
