On summer days, our attic gets crazy hot. At night, this heat radiates back into our house, and our AC has to work extra to combat this stored heat.

Roofs already have vents to reduce the trapped heat. Why can't houses have a ridgeline that raises up for several minutes when the inner and outer heat differential is great to let the hot attic air escape?

I am sure that if our roof did this at sundown every night, our electric bill would be significantly reduced. Also, it would probably extend the life of the roof.
