Skylight Leak in National City, CA.
A leak around a skylight in National City is almost always a flashing or seal failure, not a defect in the skylight glass itself. Water finds the gap where the skylight frame meets the roof and works its way in from there. Most skylight leaks in Central are a contained, fixable repair.
Skylight Leak in Central San Diego
Central San Diego's mix of home ages around National City means skylight leaks here range from original 1980s units with outdated flashing to recent installs with a simple seal failure. A roofer checks the skylight's age before diagnosing the cause.
What causes a skylight leak and what to do
Skylight flashing takes more stress than the surrounding roof because it has to seal a hard edge where the frame meets the roofing material, and that seal degrades with age and movement. In National City, a roofer traces the water path first, since a leak that shows up only in wind-driven rain often points to a different spot than one that leaks in any rain. Reflashing the skylight usually solves it; replacing the skylight unit itself is only needed if the frame or glass has failed.
National City runs older 1940s-60s craftsman and ranch stock with significant multi-family inventory along the SR-54 and 8th Street corridors. Composition shingle on single-family, low-slope membrane on the multi-family, both reaching replacement window in coordinated waves.

National City a skylight leak questions
Is my skylight leak from the glass or the flashing in National City?
Nearly always the flashing or seal around the frame, not the glass itself. A roofer in National City traces the actual water path, since a leak appearing at the ceiling doesn't necessarily mean the entry point is directly above it.
Do I need a new skylight or just a reseal?
Most skylight leaks are solved by reflashing and resealing around the existing unit. A full skylight replacement is only necessary if the frame has warped, the glass seal has failed internally, or the unit is decades past its rated life.
