Common Water Issue in BC
Skylight Leaking — Roof Penetration Leak Detection
Skylights are common roof penetration points that frequently develop leaks in BC's rainy climate. Failed flashing or sealant can cause water to run down walls and ceilings far from the skylight itself.
Possible Causes
- •Failed skylight flashing at roof junction
- •Deteriorated sealant between skylight frame and roof deck
- •Cracked or failed skylight dome or glazing seal
- •Clogged skylight drain channels on curb-mounted units
- •Condensation within skylight frame mimicking a leak
Recommended Steps
- 1Check if leak appears during rain only — confirms roof penetration issue
- 2Inspect skylight from exterior if safely accessible
- 3Check for damaged or lifted flashing around skylight base
- 4Clear any debris from skylight curb and drain channels
- 5Call professional roof leak detection with thermal imaging for accurate diagnosis
