I've installed vent covers - and the directions always say to screw into the vent frame. I'm about to do that again :-)

But that being said - I just tore out a non-powered vent and replaced it with a Fantastic Fan. The good news/bad news: the Dicor used to install the original vent back in 1998, was STILL sticky/gooey (a true PITA to remove) and there was no sign of water intrusion anywhere. I have a LOT of faith in Dicor to keep things sealed up tight.

If it wasn't for the fact that there will be holes in the roof screwing down into the roof makes a better installation IMHO.
I have installed two sets of covers using the recommended brackets into the opening wall and there can be issues: the screws into the wall can come loose from the vibration of the overhung load of the cover and the bolts/nuts can come loose for the same reason. Those nuts/bolts should be checked on occasion. I've had them loosen. and the overhung load isn't the greatest idea for an RV that bounces around like ours does.

What's done is done. I don't like holes in roof if not needed. These were not needed, but they are there. With proper maintenance, they will NOT leak, just like all the other MUCH LARGER holes in the roof 12"x12" vents, plumbing vents, antennas, etc. that will NOT leak if properly maintained. Plus my rig is under a metal carport that I built especially for it....to protect t from the sun damage as it rarely rains in SoCal

I would also be worried that they may have sealed the base of the new cover to the roof. They need to be able to drain any water that finds it's way inside the cover. If they screwed the base of the cover down to the roof, they may have put a bead of dicor down first. THAT would be a problem.

Normally there are L shaped brackets screwed to the sides of the vent frame, and they stick out and the cover sits on and is screwed to them, the cover actually does not touch the roof and may sit off of it as much as a quarter inch. It they screwed it directly to the roof it was a half ass job and they threw away the parts kit and the instructions. Shop manager not paying attention to what is going on and people who don't know and don't care.

Maxx Air II fans can be mounted to the vent housing or the roof as the dealer did. Also a Maxx air OEM fan has built in eyes in the bottom flange of the fan housing that the cover simply clips to with the snap pins, although when used OEM like that the cover ends up sticking into the sealant as its too close to the roof surface.

It all depends on the vent housing, with some and most of the newere plastic ones the supplied brackets when attached to the vertical sides of the vent housing will not line up properly for the snap pins.

Ahh...deltabravo- used your video as my guide to do my MaxxFan install back in Jan. Very nicely done, and helped tremendously.

Not sure why I waited so long to do the replacement of the OEM fan. that think is a pos. MaxxFan is wonderful.
