To avoid significant water damage in your RV, it is essential to keep up with roof seal maintenance. A tiny leak may not seem like a big deal, but it can create a very dangerous situation for you and those using your RV. Before you know it, mold could take over, or water damage could ruin your RV's interior and exterior walls. So today, let's go through everything you need to know about your RVs roof sealant.

How Often to reseal

According to our RV manufacturer, the roof should be inspected every six months to catch minor problems before they become large, expensive problems. I look over the sealants every time I get on the roof about once a month.

However, you don't need to reseal your RV roof that often. Typically the sealant will need to be completely removed and replaced every 8-10 years. Ruby, our 35 foot motorhome, is getting close after seven years. We will need to remove all the sealant sometime next year to prevent significant water issues down the road.

Deciding which sealant to use

Stack of owner's manuals

Many RV Roofs exist, including rubber, metal, and even fiberglass roofs. So it is essential to choose the best sealant for your specific roof. Using the wrong sealant on your RV roof can damage seals and cause a bigger problem. Always check with your RV manufacturer to see what sealant they recommend.

The area and size of the repair will be a factor in determining which sealant to use.

Another thing to consider before choosing your sealant is will you need rigid or flexible sealant. Flexible sealant can handle expansion and contraction with high temperatures. Rigid sealant is not flexible and is prone to crack.

Finally, UV resistance should be a consideration. It will prevent your sealant from being damaged by the sun’s heat and UV rays.

 
 

Types of sealant

There are a couple of options that you can use when sealing an RV roof. One of the most popular types is a liquid sealant. A liquid sealant often comes in a tube and needs a caulking gun for application. This sealant is an easy way to address large and minor fixes. Check with the brand of sealant for instructions.

Another popular option is sealant tape. This tape forms an airtight bond to help prevent water from penetrating gaps. A sealant tape is great for roof repairs but also preventative maintenance.

Even if you cannot get on the roof, it should be inspected regularly. You can find an RV technician to inspect your roof through the RV Technician Association of America’s RV tech locator. Once on the website, type in your current city and state, and it will show you all the certified RV technicians in your area.
