What is tiger striping on gutters you ask? They are darkened lines that appear on the face/ or front of the gutter. They are most prominent on white gutters and most homes have these stripes.
Some homeowners are led to believe that water overflows from the gutters and causes tiger striping on the face of the gutter. In actuality, most stripes are caused by rain water hitting the top and sliding down. Some paint finishes play a large role in tiger striping.
