Why is the gap still leaking even after applying silicone, and should I reapply it or is there a different solution?

Hey, does anyone have an idea why it’s leaking from the gap there? I noticed there was silicone there, but it was still leaking even with it. Should I just put more silicone on it, or is there a better way to fix this?
Is there a leak? If you’re finding water above your bathroom ceiling, it’s important to investigate the cause as there shouldn’t be any water coming from there.
Condensation might be forming due to the contrast in temperatures between the cold outside and the heat on inside. Consider changing the fan and housing, and sealing any gaps while you’re at it.
Also, consider using insulated ducting to minimize the condensation. Before that, be sure to check the attic for any indications of a roof leak.
Hey, thanks for the info. The dripping only happens after I take a shower and run the water. It usually starts about 30 minutes later, which does make sense.
It’s most likely not vented outside, but into the attic – I’ve seen it happen many times.
I took a quick look in the attic and it appears that all the moisture is going towards the outdoor vent.
Seems like it’s condensation, so I wouldn’t seal it until the main issue is resolved – either insulate the exhaust ductwork and ensure it vents through the roof or sidewall, not into the attic. I suggest replacing the fan while you’re handling it. Fans are cheap and simple to replace. Best of luck!
Yep, if you seal the water in there, the issue disappears!
That’s pretty much what I was thinking too haha. Why can’t people just do things correctly?
Make sure to insulate the vent that goes from the fan to the hood.
Have you noticed any water leaks or dampness? Bathroom fans can corrode due to moisture. If your attic is chilly during winter, air seeping through gaps may lead to condensation when steamy hot showers happen. Try insulating the area around the fan in the attic by filling the space between the fan box and wood framing.
