WHAT ARE TIGER STRIPES?
Tiger stripes, those dark vertical stripes that appear on aluminum rain gutters. Customers sometimes call us about these dark stipes that will not wash off. The first assumption is that the paint has gone bad. This is usually not the case. Naturally, pollution and dirt build up on the top lip of the gutter. When moisture combines with these pollutants, it streams down the face of the gutter. Future precipitation will continuously follow the same path. Over time, the buildup becomes alternating light and dark stripes. Rain gutters require regular maintenance to prevent the normal buildup of soil deposits and oxide accumulations. The level of maintenance depends solely on the atmospheric conditions in a geographic region.
