Did an energy audit on a home and found an attic that was:
Not sealed nor properly ventilated. A previous contractor vented the bathroom vent directly into the attic. The hatchway leading into the attic was not air sealed. I expect there are a lot of other entry points into the attic for warm moist air from the living space.
This is the most horrid condensation on the interior of the roof deck I have ever seen. The roof is fairly new and the homeowner claims that the attic is dry during the summer. So I don't think I have any roof leakage issues.
I can't insulate up here until the attic is dried (and yes.. there is mold growing). I have to remove all the existing fiberglass (its wet also), air-seal the attic, vent the bathroom directly to the outside (stop the moisture from getting in to begin with).
I haven't figured out how to dry out the attic before insulating though. I was looking at drying out the attic like I would a crawl space: renting some dehumidifiers, installing some heat lamps, but not sure if this will be enough. Anyone here have suggestions?
