If you are in need of an RV roof repair because of a jammed or stuck exit air vent, you might get lucky and be able to repair the vent by simply spraying some WD-40 (or other penetrating oil) on the louvers and blades of the vent. However, this is usually a temporary fix at best. Therefore, it is usually a much better idea to simply replace the eighth at an event on your RV. Replacing the van is much easier than you might think, and this simple step-by-step how-to guide will show you everything you need to know. Let's get started.

Step 1 - Purchase Replacement Roof Exit Air Vent

This is a local recreational vehicle dealership that tells your make and model RV. Participates in air cover for your particular model. Even if an exact match is not available for your exit air vent, the dealer should be able to provide you with a vent of the same size that will work. You don't need to really worry about the screw holes for the new vent lighting up with the holes use for the old one. In fact, it is a much better idea to create new screw holes as this will help created that are still around the vent and prevent air and moisture from in your RV when the vent is not open.

Step 2 - Prepare to Work 

Take the ladder and place it on the side of your RV. If you want to protect the paint on your RV, you can take a couple of old T-shirts and wrap them around the edges of the ladder at the top. Then, have someone help you move your tools up on top of the RV.

Step 3 - Remove the Old Exit Vent

Located the screws that hold the exit air vent in place on top of your RV. Sometimes, they are covered with caulk to help prevent  moisture from getting in to the vent. Therefore, you may need to take your putty knife and dig around in the caulk so you can find the screws. Once you find the screws, remove them and then use a flat head screwdriver to help pry the vent out of its hole.

Step 4 - Scrape and Sand Away Old Caulk

Use a putty knife and scrape away all of the old caulk. When you have almost all of the caulk scraped away, take a piece of sandpaper and sand the edges of the hole where the new exit air vent will be installed.

Step 5 - Pre-Drill Installation Screw Holes

Take the new exit air vent and set it into the hole opening in your RV. Then, take a pencil and mark where the screw holes need to be drilled. Remove the exit air vent.Take a drill bit that is slightly smaller than the installation screws and drill pilot holes.

Step 6 - Install New Vent

Set the new exit air vent in place and tighten down the screws securely with a screwdriver.

Step 7 - Caulk the Edges Around the Vent

Use your caulk gun and a high quality exterior silicone based caulk to caulk the edges of the new exit air vent.
