What does attic ventilation include?

Attic ventilation encompasses various designs and configurations, not limited solely to accessible spaces. It is essential for regulating temperature and moisture levels, contributing to the overall health and efficiency of a building. This includes roof structures without accessible attics, acknowledging that even these areas can benefit from ventilation systems to assist in heat exhaust and moisture control. Proper ventilation in these roof areas can help prevent issues such as ice damming, mold growth, and roof structural problems.

When looking at different types of roofs, ventilation may occur through passive systems like vents located at the eaves and ridge, or through active systems that involve fans. Thus, the configuration of the roof, whether sloped or flat and whether it includes an accessible attic or not, plays a crucial role in the ventilation approach. This broad definition supports effective climate control across all roof types.
