Common Water Issue in BC
Attic Moisture — Condensation or Roof Leak
Moisture in BC attics can be from condensation (ventilation issue) or a roof leak. Identifying the source is essential for proper remediation.
Possible Causes
- •Inadequate attic ventilation causing moisture buildup
- •Warm air leaking from living space into cold attic
- •Bathroom or kitchen exhaust fans venting into attic
- •Roof leak allowing water entry at flashing or shingle defect
- •Ice damming forcing water under roof sheathing
Recommended Steps
- 1Check attic on a dry sunny day — if moisture is present, it is condensation, not a roof leak
- 2Ensure bathroom and kitchen fans vent outside, not into attic
- 3Check attic insulation — should not block soffit vents
- 4Use a flashlight at night in attic to check for light coming through roof — indicates hole
- 5Call professional inspection combining thermal imaging with attic assessment
