How Do Tiger Stripes on Gutters Form?

Tiger stripes are dark brownish or blackish vertical lines or streaks that appear on the front of the rain gutter. They usually start from the gutter lip and run down the front to the bottom edge of the gutter. Sometimes, these dirt lines can continue down the fascias and siding.  The unsightly lines are most often seen on white or light colored aluminum gutters and can reduce your home’s curb appeal.

These striped discolorations form due to dust, dirt, pollen, and mildew buildup on the lip of the gutter. Other pollutants are insecticides, tree sap, and chimney fumes. When moisture from dew, raindrops, or other forms of precipitation combine with the dust, dirt and other debris; a grimy solution forms.

It then slowly trickles down the face of the gutter. This cycle will continue until your gutters are cleaned. Oxidation can also cause the streaks to stain the surface and make them even more difficult to clean.

Is Cleaning Tiger Stripes a DIY Project?

Although tiger stripes themselves may not be deadly, attempting to clean them can be! According to the World Health Organization, falls are the second leading cause of accidental deaths around the world. Falls cause approximately 424,000 deaths and millions of ER visits each year. Did you know:

  • Falls account for approximately 3/4ths of all roofing industry fatalities
