Ventilating into roof space

Our first floor bathroom has no ventilation, and is very wet after a shower.
Our walls are very thick, and it will be a large job to put a ventilation fan in the walls. Can we ventilate into the empty roof space? (It's definitely not very sealed up there!). Or will it make it damp?
(We have a separate loft space that we use for storage.)
We can get a new window put in with trickle vents, and open windows etc, but I think it won't be enough.
Any other ventilation ideas?

I will start by saying I know nothing about this but if you are worried about the loft getting wet can you put the vent all the way out of the roof?

I would go in to the loft space and then have a duct going to the eaves.

Our bathroom has no window and has an extractor fan that is ducted through the loft space and out of the eaves.

Ah! Yes, that of course makes much more sense. Thank you!

Our bathroom has no extractor fan , just open the window when showering and leave it open after… no dampness , no mould .

We've vented through the roof in both our bathrooms. You can buy a vent kit that comes with an extendable tube. The fans are more expensive than wall fans though.
You'll also need a replacement vented tile for the roof which is plastic.
My DP did both vents himself and it's not a difficult job.

OP, like you mentioned, our main bathroom also has walls too thick for a fan, so roof ventilation was the obvious solution.
