The most typical problem associated with skylights is water leakage, which can stem from several different structural and environmental factors. Leakage most frequently occurs due to the breakdown of exterior caulking, aging rubber gaskets, or damaged and improperly installed metal flashing around the base of the skylight curb. Another extremely common issue is indoor condensation, which occurs when warm, humid air inside the home rises and meets the cold glass pane of the skylight, causing water droplets to form and drip down into the living space—a phenomenon often mistaken for an exterior roof leak. Additionally, issues like seal failure between double-paned glass resulting in internal fogging, as well as physical damage from severe hailstorms or falling tree branches, also rank among the most frequent challenges homeowners face with their skylights.
