Quick question on your insulation for the ceiling -- If I recall you have an unvented roof. Are you only using cellulose in the roof rafters?
I ended up going with an unvented design as well. However, in order to meet the r-value code requirements (recently changed to r-38) and to make sure it is a tight space, 2 different insulation contractors recommended 2" of closed cell foam, followed by 7" of cellulose. On the roof we used standard roofing felt for breath-ability. This is the way I am currently going -- I know the closed cell won't help with sound...
