Q: For the last four years, my wife and I have been building a house. She decided on open beam ceilings in the living room so we put up insulation. But, before we could put up the sheet rock, winter came. From the heat and the cold mixing, we have about two inches of condensation between the insulation and the roof. If I put the insulation up against the roof, will that stop the dripping or do I have to put vents on the roof? Thanks. — Sean, Corbett, OR

A: Richard says: I'm not sure I understand enough of what your condition is but I will offer you two caveats to insulating. First, the roof surface (where the shingles are applied) should be cold in the winter so you need to ventilate, ventilate, ventilate. The second caveat is to see rule one again. The bottom-line? Ventilate.
