StainGuarder® - What Causes Gutter Staining?

Video Note : The left side of this gutter section shows with StainGuarder® installed, contaminants and liquid are completely channelled away fromt he gutter face preventing any staining. The right side without StainGuarder® allows water to stick to (due to surface adhesioin) the face of the gutter, causing and allowing the gutter face to become stained, streaked and "tiger striped". StainGuarder® also reduces ice formation (icicles).

New gutters on a house are one of the first exterior finishes on a house to stain and lose their new appearance. Within a few short months (sometimes weeks) new gutters will begin staining, streaking and get what is known in the industry as "tiger striping".

The cause of staining : There are several factors that lead to and cause gutter staining including petroleum-based run-off (roof-shingles), tannic acid from leaves, pollution, acid rain, pollen, general dirt and debris as well as various other contaminants all leading to gutter staining.

These harsh contaminants along with certain atmospheric conditions lead to contaminant filled condensation and forms a bond with the gutter surface that allows the inevitable staining and blackening of the gutter face. This condensation that accumulates on the top horizontal edge of the gutter eventually runs down the gutter day after day and in short order begins the staining process.
