How to fix a sagging roof on a pop-up camper by yourself

A pop-up camper or trailer tent roof is raised through a system of pulleys and cranks. Improper storage and care of the pop-up camper, including keeping it exposed to the elements, causes the vinyl roof to rot in some places and what we know as a sagging roof. 

If the damaged sections do not compromise the integrity of the camper, the pop-up roof can be restored instead of replacing it.

Here’s how you do it:

  1. Clean the damaged area on the inside and outside of the roof with a mixture of a spoon of dishwasher liquid and four cups of hot water. Dry at the cleaned area with a soft cloth to remove excess moisture without causing further damage.
  1.  Draw a square around the damaged area with a permanent marker. Cut the canvas along these lines with a sharp pair of scissors to remove the damaged area, creating a repairable hole.
  1. Cut two pieces of canvas, which is provided in the vinyl repair kit, slightly larger than the hole prepared in step two. Locate a vinyl repair kit from a local home or camping supply store that matches your pop up camper roof colour.
  1. Apply a thin layer of the kit’s vinyl adhesive around the hole on the inside of the RV roof. Center the patch over the hole, and hold it in place for 30 seconds. Let the glue dry for an hour or two.
  1.  Apply a thin layer of the kit’s vinyl adhesive around the hole on the outside of the RV roof. Center the patch over the hole, and hold it in place for at least 30 seconds to allow the glue to set.
  1. Allow the glue to set for another 24 hours before lowering the roof or using the unit.

Some useful tips:

  • Cover the pop-up camper with a plastic tarp or store it in a garage when not in use, especially during the winter.
  • Purchase a vinyl repair kit with the “waterproof” label. If one cannot be found, spray the exterior of the roof over the patch with waterproof silicone spray after the glue is allowed to set for at least 24 hours.
  • It is recommended that you replace the roof of a pop-up camper entirely that is badly rotted or damaged.
