So...If I had a vent on my roof the extreme hot air could escape in
summer, probably reducing or eliminating my condensation problem. But in
winter this vent would need to be closed.

Does anybody out there know of a roof vent that can be opened in summer
yet switched off in winter?

Since it's going to be in a visible location, how about a good
quality skylight that opens?

That's worth considering.
Thanks.
