There must be inlet and outlet. Air must be able to enter at the soffits therefore a gap must be left where the roof meets the wall.
Spacers are available at home improvement centers which keeps the insulation from touching the roof in this area.
A general rule of thumb in most areas is 1 sq.ft. of vent for every 300 sq.ft. of attic.
