My bathroom ceiling has a small slow dripping leak that comes and goes! I have a ceiling fan that is about two feet from the area in question. I run my fan during the showering phase and for about 15 to 20 min after a shower. I have been in my attic many times looking for leaks in the roof and don't see anything stained on the sheeting. Also have looked at the shingles all over the roof and didn't see any areas of question! Do you have any ideas?
