Roof-mounted intake vents are unreliable in snowy climates because snow blocks the airflow, causing the ventilation system to fail. This leads to ice dams and moisture buildup. Instead of relying on these vents, focus on air-sealing the ceiling and increasing attic insulation to keep the roof deck cold.
Roof-mounted intake vents frequently fail in cold climates when buried by snow. Learn why this happens and how to manage attic ventilation effectively.
Installing intake vents in cold climates requires careful planning. Learn why edge vents may fail in snow and how to effectively prevent ice dams.
