Wet Insulation in Attic — Roof Leak or Condensation

Wet attic insulation in BC homes indicates a roof leak or condensation issue requiring investigation before mould and structural damage develop.

Possible Causes

  • Roof leak from damaged shingles or flashing
  • Ice damming forcing water under roof sheathing
  • Bathroom or kitchen exhaust fan venting moist air into attic
  • Inadequate attic ventilation causing condensation
  • Plumbing vent pipe leak in attic space

Recommended Steps

  • 1Locate wet insulation area and note position relative to roof features above
  • 2Wear protective gear (mask, gloves) when handling wet insulation
  • 3Check bathroom and kitchen fan exhaust terminations — should vent outside, not into attic
  • 4Improve attic ventilation with ridge and soffit vents as needed
  • 5Call professional roof leak detection with thermal imaging for accurate source identification
