Roof Vent Caulking Maintenance

Most popup camper roofs are made of fiberglass while the roof vent is plastic. Since those two materials expand and contract at different rates when heated or cooled, caulking is needed to create a proper seal. That caulking must be regularly maintained to prevent leaks. Here’s how to do it.

  1. Order a tube of ProFlex RV caulk (also available in other colors).
  2. Clean the existing caulk, vent and roof thoroughly, but don’t worry about removing the existing caulk.
  3. Apply a thin bead of caulk to both the seam of the vent and the roof.
  4. Smooth out the caulk with your finger (preferably inside a latex glove), making sure all cracked areas are now covered with new caulk. The ProFlex caulk will settle after a few hours, creating an even smoother look.

I recommend checking the caulk twice a year – once before your first trip, and a second time just before winterizing for the year.

I've been camping regularly since I was a kid, from quick Cub/Boy Scout trips to week-long backpacking trips and everything else in-between. We got a popup camper when our kids were 1 and 3 years old to enjoy more time outdoors together alongside a few conveniences like heat and running water. Since then, we've spent over 75 nights together as a family in our popup camper. I've learned a lot about the intricacies of a popup tent camper during this time and love to share those lessons here for the benefit of others.
