In sloped roof construction the Soffit area must be vented to allow fresh air intake from the Outside.  This air is drawn in through the soffits, circulated through the attic space and vented out through the output vents installed near the top of the roof line.  It is imperative that soffits vent properly or else they must be compensated for with Lower Roof Intake Vents.
