Do I Need To Close My MaxxAir MaxxFan RV Rooftop Vent With Fan Every Time It Rains?  

Updated 02/26/2026 | Published 02/25/2026

Question:

We camp in Florida and get surprise rain almost every afternoon. If I install the MA96WV, do I have to run outside and close it every time it sprinkles?

Good morning Tony, since the MaxxAir rv roof vent with fan and white lid # MA96WV (also available with smoked lid # MA36WV) is a manual lift model, you would need to close the lid during rain unless you add a vent cover. And you would not need to go outside. It closes by using the knob inside the camper under the vent. It's easy to do.

I think you might be interested in a vent cover for this situation. Installing the white cover # MA00-955001 or smoked cover # MA00-955003 over the vent lets you keep the lid open in light rain while still protecting the fan. It basically gives you all-weather ventilation without stepping up to a rain-sensing model.

If you camp in frequent showers like Florida, I’d strongly consider pairing them.

Are you replacing an existing vent, or adding this as an upgrade during a roof reseal?

That makes sense. Replacing damaged vent. If I add the FanMate cover, does it make the whole setup a lot taller on the roof? I park in a storage building and clearance is already kind of tight.

@Tony The FanMate cover will add some height above the vent, so if your clearance is tight it’s worth measuring before you commit. The vent itself sits fairly low when closed (3" above roof), but the cover does sit higher since it shields the lid (10-1/4" above roof) And since you’ll be pulling the vent to add the cover/upgrade anyway, I recommend using the Roof Vent Installation Kit # 344270KITW so you’ve got fresh butyl tape and sealant for a watertight install.
