Gutter brushes work to keep gutters clear of leaves and other debris that cause clogs. The top bristles of the gutter brush collect debris, while the bottom bristles stay clear, allowing water to flow freely through the gutter.
Leaves and large pieces of debris usually pass across gutter brushes without getting caught. Small pieces of debris that may become lodged in a gutter brush's bristles eventually blow away or decompose. They do not prevent rainwater from flowing off the roof and into the gutters. Installing gutter brushes is a simple process that involves inserting the brushes along the entire length of the rain gutters. Gutters must be clean and free of clogs before the installation of gutter brushes.
