We had a full hip on last house. Two ways to add vents Ridge Vents along ridges & Roof Vents through the roof deck. Both can be done with corrugated roof, through the deck is best in the upper portion of the roof & there are flat install panels, but not readily available here... We had shigles & added both, along with really upping the soffit venting. I have not seen the recommendation for sealing & insulation... Last I heard, sealing the attic area can bring a bunch of problems later & have seen some of the problems inc. fish lipping of the deck.
