Condensation is usually more noticeable on roof windows and flat roof windows because warm, moist air rises to the ceiling. The problem, however, usually isn't the roof window. It’s the excess moisture in the room. Condensation is more prevalent in new homes. After a few years, new homes tend to dry out and have less moisture problems. Eliminating excess moisture by using a dehumidifier and providing adequate ventilation and air circulation will go a long way in preventing condensation. Installing roofing underlay between the roof window frame and roofing material will help prevent condensation on the cladding.
