Condensation in loft - could it be bathroom extractor pipe not venting?

[lozcozard]

See attached image. The extractor fan pipe goes into the cavity between walls. Not best photo, the rafter is hiding it going in above the inner wall.

I was told this setup is common. But this half of the attic has a soaking roof, it's dripping. You can top of rafters are wet. The other side (I have an attic room in between) is dry. It's only this side that's wet. I have adequate ventilation, I've put these space things in between the felt. I can feel air blowing in there.

So only thing I can think of is the extractor fan is no good vented into the cavity between inner and outer wall. I have cavity insulation although shouldn't be any this high in attic.

Thanks

It is beyond my ken, but both ends of the extractor vent look to be very obstructed (top and bottom). That said, the lower compression should (possibly) result in water falling back down.

I'd wonder if anything is extracted through that pipe, it's crushed at both ends. Where does it go after that wall?

You need to get that either out of a vented roof tile or wall (preferably lower down).
