We live in Michigan and we recently noticed that we have drips of water coming from our Bathroom Ceiling Fan...not actually from it, but around it on the side. We get about 1 drop every 10 seconds. Is this normal condensation or something much worse, like a leaky roof? It's currently January and we are going through some very cold weather. We've been in the house for just over 3 years (the house is 25 years old), and this is the first time it's ever done this. I've seen posts where they talk about the piping, but I haven't been up in the attic yet to inspect the piping. Any advice would be greatly appreciated.
