A roof exhaust fan removes heat and moisture for fresh airflow.
Roof fans pull warm air out and bring fresh air into your home.
Fan blades create pressure that pushes hot, humid air outside.
Pick fan size based on room area, airflow, noise, and watt use.
Place the fan centrally, secure it well, and seal all gaps.
Roof fans reduce humidity, odors, smoke, and trapped indoor heat.
Roof exhaust fans cost ₹900 to ₹3,000 based on size and model.
