Picture attached of a roof vent. Long story (rental), but difficult for me to get closer. Anyway, I’m not familiar with this type of vent, but landlord says its normal for them to make noise in wind.
I, OTOH, think it’s not normal to see the flappers moving freely from the wind coming over the roof. In other words, even with the wind not coming at them, they move. When the wind does point directly at them, they bang against the stops all night long. It gets windy in RI — that’s why they do all that sailing here. Lot’s of opportunity for the vents to make noise.
I’m thinking they have worn out or broken a spring, and should be fixed. Thoughts?
I do have a backup plan involving duct tape.
Tried reducing, hope it’s small enough for dial up. Edit, guess it is, photo didn’t attach.

They look like regular pot vents but I can't really see the pic. Are these for bath fans or what?
When using a digital camera, and you can't get up close, it's pretty easy to take a very high res picture and then use some kind of software to crop the pic to show the object you want, which also makes the file size smaller for internet use.
Really though - the first step for any repair is to have a close look, which would have facilitated a better pic... Go up there and take your duct tape with you... :-)

Thanks. Probably should have cropped the way you suggested.++++++++++++++++++

From what SeeYou said (the local roofig expert) sounds like some rubber bumpers might be the ticket to dampen the banging...
I, OTOH, think it's not normal to see the flappers moving freely from the wind coming over the roof.
Most of those vents have pretty imperfect flappers in them. When I build custom flapper vents, I add some stick-on weather stripping to the dampen the clanging.
The flapping can also be caused by negative pressure as the wind comes over the vent when it's on the leeward side.
You'll probably have to take the vent off the roof and reach thru from the inside to add weather stripping and the hinge mechanism may not allow the flapper to work right if it is weather stripped.

But you all knew that. I detailed it extensively in my blog.
I was afraid of what I think you're saying -- this is pretty normal for off-the-shelf vents with flappers and there may not be much I can do about it?Guess I may have to block them open.++++++++++++++++++

Maybe a weak magnet to hold it shut?
