For a natural ventilation of any attic and roof, there must be a cool air intake and a hot air exhaust. Mother Nature takes care of the rest. No electricity needed.

With gable vents placed at the highest level of the gable wall, they are usually the best heat exhaust vents the house could have. But soffit and cornice vents are where the majority of cool air enters to push the hot out. No matter the shape of the vent, at the highest possible point nearest the roof peak will vent the most of the heated air. This simple and Natural system is why it's been used and trusted for centuries to prolong the home's life. The two most important parts of a home is the foundation and the roof. The foundation holds everything up while the roof protects it all.
