How to get rid of mold near skylights?
First you need to fix the source of the moisture thats causing the mold. Then if the material that’s mouldy is soaked wet or damp, it really should be completely removed and replaced with that whole area dried out. If it is dry now, but the mold keeps creeping back, the only solution is to mix some household bleach with water and cover everything below and get up there and spray the solution on and leave it dry. You’ll then need to seal that area with a good sealer like Kilz. Then you can repaint.
