ABSTRACT:
The ventilating cap for the ridge of a roof includes multiple plies of ventilating material disposed on opposite sides of an opening cut along the ridge of the roof. The ventilating cap includes a connecting ply which interconnects a pair of vent parts disposed on opposite sides of the vent opening. The connecting ply is folded along a crease line, and, according to one embodiment of the invention, includes a groove which extends longitudinally along the connecting ply at the crease line to permit a consistent fold of the connecting ply. According to another embodiment of the invention, the groove consists of two channels which cooperate to form a rib running along the center of the groove. The rib stabilizes the fold, thereby permitting a consistent fold about the rib.
