An installed gutter having a main flow channel and an exposed curved front surface including an upper generally vertically disposed surface directly adjacent the flow channel for receiving any overflow from the channel and having disposed at least on the vertical portion a protective strip coating or cover characterized by having nonwater wetting characteristics. This strip may comprise any suitable material such as Teflon, polyethylene, polypropylene and the like. The strip may extend for the entire gutter length or for a predetermined portion or length of the gutter. According to the preferred design, the protective strip is secured to the gutter such that it tightly adheres to the front face of the gutter so that overflow does not seep between the strip and gutter. Other adaptations of this invention include use on bridges, overpasses and the like to prevent icicle formation.
A protective strip in combination with a gutter for securement to a structure, said gutter comprising an elongated flow passageway having a bottom, a front face and a rear face, said protective strip having a uniform thickness and a nonwettable front surface over which water from said gutter freely flows and mounted on at least a top portion of said front face of said gutter in tightly sealed relation to the adjacent front face, said strip beginning at and extending downward from the top of said gutter for a predetermined distance which is situated above said bottom, and means for securing said strip only to said front face at said top portion.
