25 Roof Leak Warning Signs (With Photos) — When to Call a Roofer for Repair

Moment #20: Skylight flashing failure

Skylights are common leak points because they create multiple seams around the frame. Worn sealant, lifted flashing, or small gaps can let rainwater in during heavy storms. Leaks may show up as staining below the skylight or damp insulation around the opening. If you see repeated moisture after rain, skylight flashing is often the first area to service. Professional resealing or flashing repair may be required.
