Wooden roof windows turn black from condensation because when warm, moist air comes into contact with a cold surface, such as the window pane, it condenses and forms water droplets. This moisture can then lead to the growth of mold and mildew on the wooden surface, causing it to turn black over time. Additionally, the lack of proper ventilation in the attic or roof space can exacerbate the condensation issue, leading to further moisture buildup and discoloration of the wooden window frames. Regular maintenance and ensuring proper ventilation can help prevent this issue. **
