Inadequate ventilation may lead to excess heat and humidity in the attic or rafter cavity. Attic rafter vents are also known as baffles. Ventilation is typically provided by some combination of gable, ridge and soffit vents. Typically building codes require that unheated attics or cathedral ceiling rafter cavities be provided with a minimum amount of ventilation.
