I started removing the wet sheetrock around my skylight to try and find out exactly where the leak is coming from. I found the leak coming from the bottom 2 corners of the skylight. It might be hard to see in the pics, but there is an opening in the corner with what appears to be some yellow caulking inside.
So my question is, what are these 2 openings for? I would like to fix the leak before I go ahead and finish the sheetrock. I thought about maybe caulking those 2 openings on the inside, but it is obvious the leak is coming from the outside on the glass. Can the seals be replaced? It is at least 20 years old.
