How To Cut A Hole In Your RV Roof And Install A Vent Fan In New Location

CAUTION: Please be careful when working on the roof or your RV.
This video shows how to cut a 14" x 14" hole in your RV roof and install a powered vent fan in a location that did not previously have a vent hole. We chose the MaxxAir brand, Maxxfan Deluxe, although the procedure will be very similar for other brands or models of vent fans.
One of the most important parts of the job is carefully choosing the location for your new hole. It has to be free of structural components of the roof and electrical wiring. You will probably want to contact your RV manufacturer for a plan drawing of your particular rig, unless you know the layout of the roof super structure, to make sure the location you choose to cut a hole is free of any obstructions. My roof has steel cross members on the roof, so a strong magnet was very helpful in locating them. Your RV's building components might be different than mine.
You will need one tube of Dicor lap sealant, a roll of putty tape, some basic hand tools and a saw to cut the hole. We used a small sabre saw. It only took us a few hours to complete this job and we are very happy with the results. Good luck installing your new vent fan...you can do it!
