How to reseal an RV roof: Stay dry and protect your rig!

Knowing how to reseal an RV roof and keeping up with this critical maintenance step can add years to the life of your RV. Follow our simple instructions for trouble-free travel.

How often should you seal your RV roof?

Rain, UV light, detergents, harsh weather, and other factors will gradually wear out the roof on your RV or trailer. Left unattended, roofing materials can weather and dry out, leading to small cracks that can cause leaks. 

Good maintenance can prevent this from happening. A key to a well-kept RV or trailer roof is regular checkups to take note of and repair any areas showing wear. It’s also necessary to reseal the entire roof periodically. This not only prevents leaks but will extend the life of the roof.

If your RV roof is topped with rubber, vinyl, or a similar material, you will want to seal the trailer roof surface every 2 or 3 years to keep it in top condition. Many RV roofs are now made of synthetic materials, so check your owner’s manual or with the manufacturer for a compatible sealant.

How to seal the roof of an RV: What you need to know

Wondering how to seal a camper roof? This is how to get started: Thoroughly clean your RV roof before doing maintenance work. This will expose any small cracks or areas that need attention. 

As you inspect the roof, be especially observant of the condition of the sealant around skylights, air conditioners, fans, and other items that are mounted on top. Inspect the seal around any roof penetration, such as where wires, antennas, or pipes enter the RV.

Repair or tighten any loose fixtures or broken parts. Exterior adhesive or a patch kit can be used to repair minor tears as well as more extensive damage.

Once repairs are done, you are ready to reseal the RV roof. Here is a list of tools and supplies you will need:

  • caulking gun (if using cartridge-type sealant)
  • sealant tool for smoothing and shaping 
  • putty knife or utility knife
  • clean cloths

Follow these steps for a thorough reseal of your RV roof:

  1. Scrape away any damaged or loose sealant with a putty knife or razor. (A heat gun can be used to soften stubborn sealant.)
  2. Apply sealant anywhere there is a gap, crack, or additional coverage is necessary. Be sure to check all seams, corners, and fasteners on the roof. 
  3. Smooth out the sealant and feather the edges with the sealant tool or a gloved finger.
  4. Allow the new sealant to cure. Check the directions for drying time before driving or doing other work to the roof. Generally, this takes between 24–48 hours, see your product label for exact times.
