new roof insulation ventilation dilemma
I have dutch colonial with a gambrel roof. About to have a roof installed and trying to get my remodel up to energy star standards. It's a cold brick house. After tear off (shinles plus four layers) planned to sheath with plywood (no sheathing now) and install asphalt shingles. However, I'm stuck with how to ventilate and insulate. Building a wall lengthwise in attic to allow removing ceiling joists and raise ceiling in mbr. Can't really use remaining space because of struts and lots of moisture here so want to do natural ventilation in that portion. Any suggestions on how to get some R value from sheathing especially above raised ceiling and still ventilate remainder of attic. Has anyone done anthing like this?
