How to prevent leaking skylights?

Preventing skylight leaks requires proactive, routine maintenance and early intervention before minor wear turns into major water infiltration. Start by inspecting your skylights at least twice a year—ideally in the spring and fall—clearing away accumulated leaves, pine needles, twigs, and dirt that can block water drainage channels around the frame. Check the exterior metal flashing and counter-flashing annually for loose fasteners, rust, or gaps where sealant may have weathered away. Examine the interior drywall or wood framing around the skylight for any early discoloration, peeling paint, or dampness, which indicate minor seal failures before active dripping occurs. Additionally, ensure that your attic maintains proper ventilation and insulation to prevent internal condensation from forming on the cold glass surface and trickling down into your home.
