I have a skylight installed about 3 years ago and never check out how it looks like inside the attic. My attic is quite high. Few days ago, have someone installed a bathroom exhaust fan. So I took chance to get in and found that it is like a big chimney. I also found heavy moisture gathering on the attic ceiling at the lower side of that Chimney, also moisture found inside the plastic sheet that hold the insulation around it. I asked the exhaust fan installer, though he is not an insulation expert, but helpfully to check around, he confirmed that is the condensation rising and soaked the plywood ceiling, but he don't how to fix that. This may be a big problem for me. I wish to know how to eliminate the moisture built up there. (see photos)
As we can see the chimney is round-up with insulation and plastic sheet. Condensation/water appear inside the plastic sheet too, then rise and soak the ceiling. That is what the fan installer told me.
I hope some experts can tell me how to fix this problem. Thank you so much.
