What type of ventilation is installed on the ridge of the roof to allow warm air to escape?

Ridge vents are installed at the peak of the roof and play a crucial role in allowing warm air to escape from the attic space. As warm air rises, it accumulates at the highest point of the roof. The ridge vent provides a continuous opening along the ridge line that facilitates the outflow of this warm air, effectively managing attic temperatures and promoting better air circulation within the structure.

This ventilation method is particularly effective because it helps to create a balanced airflow system when used in conjunction with other vents, such as soffit vents, which draw cooler air into the attic. By allowing warm air to exit, ridge vents help prevent issues related to heat buildup, such as premature aging of roofing materials and increased energy costs for cooling.

In contrast, the other types of vents serve different purposes: soffit vents are located underneath the eaves and work with ridge vents to promote airflow, cornice vents are installed in the cornice boards to facilitate some airflow but are less commonly used, and gable vents are typically positioned on the gable ends of a building and permit less controlled ventilation, primarily based on prevailing winds.
