Abstract: A method for preventing clogs in a gutter assembly having a horizontal gutter with an end wall and a vertical leader connected to the gutter via a hole in a bottom of the gutter. The following steps are completed in the method: 1. removing the vertical leader from the gutter; 2. sealing the hole in the gutter; 3. removing the end wall of the gutter; 4. attaching a first end of a flexible tube to an end of the gutter where the end wall was removed so that water and debris flows through the gutter and into the flexible tube; and 5. attaching a second end of the flexible tube to the leader, so that water and debris from the flexible tube flows through the leader and out onto the ground.
