ABSTRACT:
A roofing vent adapted to be installed in the attic space of a building so as to communicate between a soffit zone and the attic space to improve the circulation of air therein and a special tool to facilitate the installation thereof. The roofing vent comprises an open-ended channel having a generally U-shaped cross-section and a plurality of transversely extending notches integrally formed in the bottom surface of the channel at spaced apart locations. The installation tool comprises an elongated handle having a vent gripping working surface at one end thereof. Also located proximate to this working surface is a roller member having its axis of rotation generally parallel to and a predetermined distance above the vent engaging surface. The length of the handle is such that an operator may stand in a location where the pitch of the roof permits sufficient head room for convenient working. By manipulating the tool, the roofing vent may be located proximate the intersection of the roof rafters with the ceiling joists.
