My parents' home in southeast Florida faces southeast and is about 4 miles from the ocean. They designed and built their home in the late 1960s. They have a terra cotta hip-tile roof with a medium pitch and four-foot overhangs. There are no roof leaks. Thirty-six inches of the underside of the overhang features corrugated perforated aluminum soffit. They have a brand new roof-mounted 6-ton Carrier heat pump heating/airconditioning unit. All the ductwork in the attic has been repaired and inspected and has no leaks. However, on the ceilings in rooms on the west/northwest side of the house there is a continuing problem with condensation around the AC vents that is damaging the plaster. If the roof doesn't leak and the ductwork doesn't leak, where is the water coming from? One handyman checked my parents' attic humidity levels, which were very high on the west/northwest side of the house. He suggested that moisture was getting into the attic through the corrugated soffit under the overhangs and that my parents should block them. Aren't attics supposed to get ventilation? Why is the moisture problem only on one side of the house? Does anybody have any suggestions? Thanks.

Hi staplesa43,

As you know, when warm air comes in contact with a cooler surface, the moisture condenses OUT of the warm air onto the cooler surface.

If the ductwork isn't insulated, then what you're experiencing is an eventuality. Yes, usually attics are to be vented. How and how-much, depends. Convection will cause a transfer of heat and cold between surfaces. That could be contributing to your problem depending on which 'side' of the situation is warm, and which side is cooler.

Insulate and leave some 'space' around the ductwork, and you should be fine. Of course, I can't see it from here. My best to ya and hope this helps.
