Background: New roof this August, ridge vent running the entire length of the house, also lots of soffit vents. I went up in the attic this morning this morning because I noticed a spot of water on a vaulted wall. It turns out that the entire attic is covered in a very thin layer of frozen condensation. The humidity in the house has been about 35-40% consistently as of late, though I did just get a humidifier because my throat was not dealing well with the dryness. We had it running all night and it filled the bedroom with approximately 1.5 gallons of water. Think that was enough to cause all the frozen condensation there? That is where a majority of it sits in the attic. The wall that I noticed was sweating is the bedroom wall, as well.
