Open attic windows for last-resort ventilation?
I paid too little attention to the section on attic ventilation in our inspection report before buying our 1928 farm house in Wisconsin. The inspector wrote, clear as day: INADEQUATE VENTILATION. I'm fairly sure that there are no gable or soffit vents, but these weren't mentioned either way in the inspection report.
I hope to be having an energy audit very soon (in next month or two) to give me a comprehensive sense of what needs to be done.
My question for now is: should I leave the two windows on either side of the attic open to ensure that the attic is cold enough to prevent ice dams? I realize that the ventilation may be uneven and/or remain inadquate. But is it still worth doing until the auditor gives me his/her opinion on the situation?
Thanks for any and all thoughts!
