Water diverter and related methods

A water diverter for installation between siding panels of exterior siding includes a diverter body elongated in a longitudinal direction between first and second ends. The diverter body defining a channel extending in the longitudinal direction and has first and second edges extending in the longitudinal direction and defining an opening into the channel therebetween. The first and second edges can each be angled inwardly toward each to form first and second hooks, such that either one of the first and second hooks can be snap-fit into a horizontal junction between the siding panels and water flowing down the siding panel above the water diverter enters the channel through the opening and exits through at least one of the first and second ends.
