Skylights bring natural light into vaulted ceilings, but they are also vulnerable penetration points. When water drips down a skylight shaft, determining the exact cause is essential for a lasting repair.
Our technicians at Pittsburgh Roofing Specialists specialize in diagnosing complex skylight and chimney leaks.
3 Primary Causes of Skylight Leaks
1. Worn Glass Frame Rubber Gasket
Over 15 to 20 years, UV exposure degrades the factory rubber seal surrounding the glass pane. Water seeps past the glass frame and drips onto interior drywall.
2. Perimeter Step & Header Flashing Failure
Skylights rely on metal step flashing along the sides and a continuous top header flange. If metal flashing corrodes or sealant separates, water channels underneath surrounding shingles.
3. Condensation Misdiagnosed as a Leak
In cold winter weather, warm indoor humidity condenses on single-pane skylight glass, trickling down interior drywall frame corners.
