Abstract: A ridge vent for a roof includes a body having a first end, a second end located opposite the first end, a first side, and a second side located opposite the first side. The vent also includes a plurality of ports formed in the first and second sides of the body. The ports have a shape that permits the vent to be installed on the roof using a nail gun. An interlock system provides a positive and accurate interlock between adjacent vents when a series of vents are required to cover the ridgeline of the roof. The vent further provides a mechanical means for reliably mounting a filter, such as a spun-bond fabric weather filter, to the vent during manufacture and for retaining the filter in place during installation of the vent.

Abstract: A shingle ridge cap cutter utilized for cutting uniform sections from roof shingles comprising a frame along which a shingle is guided to a manually operated cutter that comprises spaced blades that are moved to sever a section of the shingle. The cutter blades are provided in spaced-apart, non parallel relationship so that a combined rectangular and trapezoidal-shaped ridge cap is made by single movement of the cutter with the roof shingle positioned so that the cutter blades are aligned with the slots along one edge of the shingle. Provision is made for operation to prevent injury to the hands of the worker.
