Best way to vent (or unvent) roof?
I am looking for suggestions on how to handle insulating this roof. The main problem is that where there are gables, there aren't any eaves for venting. The house is in Zone 6, I am looking to get R100 by insulating the rafter plane with dense pack cellulose.

Neither idea seams great and spray foam would be very costly.
