Master Flow® power Roof ventilators (roof or gable mount) are your best overall investment in attic ventilation. While they may cost more to install than other types of ventilation, they remove the greatest volume of hot and/or humid air from your attic, saving you more in heating and cooling costs than any other type of ventilation!
