I have a gable roof with ridge vents on both ends and got a new metal (aluminum) roof a few years ago and my attic temps dropped considerably - just from going from asphalt shingles to the metal.

Got the gable vent sealed up and much of the ridge vents along the highest ridge just above the powered fans.
This roof is a combination of hip and one single vented gable. My plan is to evaluate the performance of the fans before sealing up the ridge rents along the hips.
