The presence of GutterBrush decreases winter gutter icing. The GutterBrush flow channel improves winter drainage and decreases ice issues that originate from snow packed gutters. By improving drainage in snow packed gutters, the ice growth cycle doesn't even begin in most conditions. Without the presence of GutterBrush, snow packed gutters overflow during melting or rain, and freeze that night beginning the ice growth cycle problem.
