Well yes and no. As another poster said, for winter, you will have to
have a way to cover it or cut off the circulation so the cold air
doesn't get in.

LOL!
Nonsense. We have 35 below winters and I have never seen a turbine covered.
If it's venting an unheated space blocking it is down right dumb. It still
removes moisture from the space during the winter.

Funny but I HAVE seen them covered on the outside and it's possible
that even those not covered might have had some covering / blockage
from inside (dunno because I can't see the attic of course). I agree
that if you don't care about cold air getting inside, then no need to
do anything. And usually moisture isn't a problem in winter for
unheated areas.
