It’s all about airflow
Roof ventilation is based on the simple fact that warm air rises. In summer, the sun heats air in the attic. In winter, heat from your home warms attic air. In either season, good venting occurs when cool air can enter the attic near the eaves and exit near the peak. Ideally, half of the vent area should be low and half high. The ultimate goal is that the temperature and humidity levels in the attic space match the conditions outdoors.
