A ventilator (10) for disposition along a roof ridge for venting the internal atmosphere in an enclosure is provided. The ventilator (10) includes a sheet-like cover (12) having a generally inverted V-shaped cross section. A pair of baffles (14) are disposed on the lower surface (18) of the cover (12) and include a plurality of spaced partitions (26) for supporting the baffles (14) rigidly against the cover (12). A post member (42) is disposed between adjacent partitions (26). The baffles (14) include inside (28) and outside (30) edges extending continuously along the lower surface (18) of the cover (12) having female dimples (52) disposed therein matingly shaped to interlock with corrsponding male studs (54) on the lower surface (18) of the cover (12). The inside (28) and outside (30) edges of the baffles (14) are thermally bonded to the lower surface (18) of the cover (12). A plurality of narrow vent slots (60) extend along the baffles (14). Vent slot dividers (62) between each of the vent slots (60) have triangular-shaped cross sections for decreasing resistance to fluid flow thereover.
