There are three main types of roofing ventilation:
1. Exhaust ventilation: This type of ventilation relies on a system of vents, fans, and ducts to draw hot air and moisture out of the attic and exhaust it outdoors.
2. Intake ventilation: This type of ventilation brings in cooler, drier air from outside to replace the hot, humid air that's being exhausted from the attic.
3. Ridge ventilation: This type of ventilation uses a continuous vent along the ridge of the roof to create a natural flow of air. Hot air rises and escapes through the vent, and cool air is drawn in through vents at the eaves.
