With this post I will show you how to change out a roof vent on a travel trailer. We recently bought an older unit. Honestly changing a roof vent out isn’t a hard thing to do.
Kids, you can easily go to an rv dealer or service center for this. I will however show you how to do it yourself and save a little money.
Let’s start with what you will need.
All you will need for this project is putty tape, an rv calking and of course the new roof vent. If you are in the Edmonton area, I go to RV Country Services. If not head on down to any RV dealer or part location for your supplies. Tons of vent styles are out there so pick the one you love.
Now for the fun part, replacing the vent. First you will need to remove all the old calking/sealant from around the existing vent.
For me this took the most amount of time. As you can see the person before me really overloaded the sealant.
Now I have a tin roof so scraping was easily done with a putty knife but if you have a rubber roof be sure to take your time. You don’t want to damage the rubber roof itself.
Next is remove the screws holding the vent in place. Use a drill, screwdriver or ratchet. Really what ever tool you feel comfortable with.
After this is done, pull out the vent. Do a final clean on the area once removed. Now is the time to inspect your opening for any damage. You are looking for water damage and wood rot. There could be mould if the vent was leaking as well so be sure to clean that up to.
When you are happy all is good, we can install the new vent. This step is the opposite of what you just did. First put on the putty tape under the lip of the new vent. Basically covering the screw holes and to make a seal against the roof.
Next set in the new vent and re-install the screws. Be sure not to over tighten them. Tighten just so some of the putty tape squishes out but not so much that you bend the metal lip.
After this, the most important step is next. Sealing up the new vent. For me I used Pro Flex RV calking.
Start by putting it around the screw heads.
After that is done, bead around the lip of the new vent to create a seal to the roof.
That’s all there is too it. Give it a couple of hours to set. (read the label of the product you choose) Afterward, you can water test the vent. Bring a garden hose up with you and spray the vent area. Have someone inside to see if water comes through. If leaks occur just add more sealant and if not you are done.
Add the interior trim piece and the vent install is complete. For me it took about 2.5 hours to remove all the old sealant off the original vent and about 30 minutes to remove/replace and re-seal the new vent. Time of this project will depend on how much sealant is on there to begin with.
I hope this helps you with your travel trailer maintenance. For me, this will be a spring time check each year. Enjoy your next camping trip.
