A roof ventilation system including a prefabricated ridge vent assembly with sidewalls secured at spacers. The spacers support a top cap spaced above the sidewalls which defines a net free ventilation area. The ventilation area is screened. The ridge vent assembly is maintained by mounting blocks which are secured to the ridge vent by connectors such as 2''x4'' lumber sections. The system may also utilize eave vent assemblies having a screened ventilation area. The eave vent assembly has a lip to support a trim piece such as a fascia board.
