What is more important for helping reduce heat in an uninsulated attic? The roof color or the amount (ratio to sf) the attic is ventilated?

  Hello Amanda,

  I don't know the answer. But I think it depends. The climate zone, slope direction. And I think in some local building code, roof ventilation is mandatory.
