Attic ventilation is a necessity in any house, not just one in a warm climate; in fact, houses in colder climates need ventilation even more than those in warm climates. Venting is important for climate control, but its main function is to circulate air through the attic and prevent the buildup of condensation. Vents should be split evenly between those in the soffits and those in the roof. Gable vents often function as roof vents.
