Hi, My contractor installed a metal R-Panel style roof over 1x4 purlins over existing shingles on a hip roof. The top ridge has vented ridge cap, but the hip ridges are not vented. There is wide butyl tape running down the hip ridges with a ridge cap on top. My question is that since a substantial area of the roof surface peaks at the hip ridges, shouldn't they be vented just like the top ridge?

They can be. The key is to balance air intake at the eave with air exhaust at the ridge/hip.
