With the metal roof and the changes to the attic ventilation, the house stays cooler in the summer. Windows provide natural ventilation. When the first heat wave of 2006 came through, the outside temperature was 100º F, and the attic temperature was 110º F. Inside the house however, the upstairs temperature was 85º F, and bottom floor temperature was 76º F without any air conditioning. The air conditioner was only used for a few days during the entire summer. Since the first heat wave, the highest temperature of the lower floor was 81º F, and it was generally in the mid- to upper-70's.
