  • Patent number: 6880318
    Abstract: A roof-raking device designed to safely and efficiently remove pine straw and leaf debris from roofs of houses. When attached to a lightweight telescopic or other long pole this device can be used by a person standing at ground level or on a ladder, eliminating the risk of climbing and walking on a pitched roof. Formed of a flexible, resilient material our rake-head is a one-piece injection molded device comprising a plurality of deeply curved, reinforced tines, a central housing support structure and a female flange fitting. The tines are of varying length, width, thickness and curve radius. When slight downward hand pressure is applied to the upper surface of a connecting pole the flexible self-adjusting tines form themselves evenly to any horizontal pitched roof surface, and when applied to a V-shaped roof angle where two roof planes meet, the tines flex and form themselves to both roof planes simultaneously.
