How to Replace the Roof Gasket Seal on a Coleman Popup Trailer

Last Updated: November 27, 2021

Has the rubber seal on your Coleman popup trailer deteriorated or come apart? Luckily, you can easily replace a worn-out seal. Our how-to guide will show you how to replace your old gasket with a new ABS roof seal on your Coleman/Fleetwood popup trailer.

Steps

1
Put your trailer roof/top up 6–12 inches (15.2–30.5 cm) so you can work on it. Remove the old rubber seal. Usually you can just pull it right off the roof. Sometimes you may need to slide a putty knife between the ABS roof and the old seal to coax it off.
2
Scrape off the old glue residue from the roof edge with a putty knife or razor blade. Using a clean cloth clean the roof edge with Acetone, so the new glue will stick well.

You will need about 41 feet (12.5 m) of new seal for the largest of the Coleman Popup Trailers. (Available on Amazon.com: just do a search for "Coleman Roof Seal") As you go along, put a 1/8" bead of adhesive into the groove of the new seal. One good choice is 3M 3008 Super Weatherstrip Adhesive.^{[1]

Starting from the center back of the trailer press the new seal onto the roof edge. If needed use a rubber mallet to gently tap the new seal securely onto the roof edge. Continue all around the trailer until you meet back at your starting point. Then cut the remaining seal to fit flush against the starting edge of your seal.^{[2]

Some blue painters tape will hold it up until it dries. MMM 3008 dries really fast.
