is attic vented?

I think he covered that!

any exhaust from the living space vented into the attic instead of
outdoors?

I live in western NY and the weather here for the last week or so has
been around low 30"s, I was in the attic the other day and the nails
coming through the roof are dripping water....I have a full ridge
vent, full soffit on the west side of the house(and they aren't
blocked by any insulation), and gable vents. It is definately cold in
the attic and there is about R25 on floor w/ barrier down towards
living space, the roof was replaced about 10 yrs ago....what is
causing this and should I be concerned?
