Interior, 2nd floor ceiling is knotty pine boards/slats. 2 individual slat pieces in two different areas show visible black spots that look like mold. Insulation is above these areas, then a metal roof that is about 8 – 9 yrs old. Are these leaks? What else could be happening and what can I do to clean them? Thank you!

Could be ventilation issues in the roof or high humidity in the house. Try cleaning with TSP and hot water, but more than likely it will not remove completely. It may need to b sanded to remove.
