a continous ridge vent?If not, you could have some serious problems with rot down the road.
Air needs to flow in from the soffit vents and out the ridge.By insulating the the roof you have closed off the exit of air and moisture.
Unless you use the attic space for living space,Isee no need to insulate the roof.Your attic temp should be near the outside temp,this is a good way to tell if you have good ventilation.Luck
