Through the celing to nearest attic pot vents. Thinking about adding
dedicated roof vents for both of these and insulating the runs.

Your house moisture problem could be solved by addition of an HRV (Heat
Recovery Ventilator) to the furnace.

Interesting. Looks to be out of my short-term budget at the moment but
at least I've a dropped ceiling in the basement that provides good
access to the ductwork. I have a sheet metal buddy that might be able
to help with the labor.

Another option that should be cheaper is a dehumidifier.

Do have a pump model, however it's in the shop right now for a
warranty repair to its fancy schmancy computer panel. It does help but
the heat it generates in the summer makes me shove it in a back corner
of the laundry room.

Thanks for the thoughtful reply. I'm on information overload at the
moment -- so much to think about -- but much better prepared for the
roofing estimators due out over the next few days. I often get
patronized or condescended to by contractors as being a dumb blonde so
getting some facts in hand first keeps me from wasting time with the
jerk specimens. ;P
