With a hip roof, 5' of ridge vent isn't doing anything. It's like breathing through a straw. You need either a lot of turtle backs or a power vent of some kind as mentioned.

For power vents, the solar powered ones just look too big and clumsy. Maybe it's the fact that I've seen people install them in really bad places seen from the front of the house. I like all on the back and hidden (as well as any plumbing vents).
