I have a 4 car garage and above the garage. Half the attic is used for master bath. When I went above the garage I noticed there was still tyvec around the areas where the bathroom is and any interior house sections. I noticed that the tyvec is sweeting and wet. it was a humid day I was up there but putting my hand on the paper showed dampness. 

My question is should I take out all this tyvec from the attic? I would assume with all the roof venting it should breath?
