ABSTRACT:
The roof nail extractor is a device for removing fasteners that are embedded in the surface of roof materials. The extractor has a base that is positioned flat on the top of a roof surface. The base includes mounting projections that extend upwardly from the top of the base. Each of the projections has a plurality of through holes adapted to receive a pivot bar that extends through the through holes. A hinge is mounted along the pivot bar, which pivotally mounts the lever to the base. The lever is an elongate rod having a handle coupled to its top end and a fastener engaging head disposed on its bottom end. The head is adapted to grip the top of an embedded fastener. Once the head grips a fastener the lever is pushed downward. The head is then raised and removes the embedded fastener.
