Your attic needs to breathe. Poor ventilation may lead to excess heat and moisture and potential roof system degradation. The attic ventilation options that are best for your home will vary based on the style of your roof to ensure that each attic space has a balanced system for intake and exhaust. Balanced systems need to draw in fresh air and export hot, moist air.
