<p>An apparatus eliminates ice/snow formation at roof edging and in this regard comprises a mesh casing and salt-based fill material. The apparatus may be placed into a typical gutter assembly adjacent a roof edge. The casing is flexible and degradable and comprises a salt-retaining surface, a matter-engaging surface, and a plurality of mesh apertures. The mesh apertures each comprise a maximal aperture dimension. The fill material comprises a plurality of salt pellets, each pellet comprising a minimal pellet dimension. The minimal pellet dimension is greater in magnitude than the maximal aperture dimension and thus the fill material is retained by the salt-retaining surface. A portion of the fill material dissolves in water when water contacts the fill material thus forming a flowable solution. The solution inherently has a depressed freezing point for preventing ice formation. Thus, the water-based solution flowing from the apparatus functions to eliminate ice at roof edging.</p> |
