The house I just moved into was reroofed five years ago with asphalt tile. It's been raining here (in Southern California) unusually hard--about ten days. I went into the attic and noticed that a lot of the skip sheathing and some of the framing is looking pretty dark in spots, as if it were wet. It's hard to tell by touch, but some spots defintely feel moist, too. Only one area of the roof is actually dripping so far--where the plywood decking on top of the sheathing is cut wide around a vent. So my question: Should the sheathing be bone-dry, or is it normal for water to get past the shingles and plywood and into the sheathing?
