Bathroom Vents—
carry warm, humid air from bathroom exhaust fans safely outside the home.
If a bathroom fan vents into the attic—or if the ducting is broken or unsealed—moisture builds up within the roof deck and insulation, leading to possible wood rot, mold growth, frost accumulation, and unsightly staining.
QUICK ANSWERS
Warning signs — Attic condensation or frost, damp insulation, musty odors, staining near the bathroom fan, visible mold, or water dripping from the fan
Typical solution — Confirm that the exhaust duct terminates outdoors, reconnect or replace damaged ductwork, and install or repair the properly flashed exterior vent as needed
Expected longevity: Life of the surrounding roof when properly installed
Pricing: Evaluation required (dependent on attic access, ductwork condition, and exterior vent installation)
