Q. Almost every year the ceilings on the north facing edge of my house get wet. At the end of winter there is also dripping from the tops of the window frames into the space between the storms and inside windows on the north side. Both problems are worse in the eastern corner where there are large trees. The house has Z-Brick on it and the north side is visibly wet and stays wet for weeks.

 There are no eaves on my roof, but when the last roof was installed we got rubber sheeting under the shingles and a ridge vent. Roofers have said that the problem is ice dams. But this year the ceiling is wet and we have had almost no snow. Could moisture from a bathroom without a venting fan seep into the covered entry hole to the attic and condense? Is there a way to adequately ventilate the attic? Will heating cables help?
