What is a rainwater diverter and do I need one?
A rainwater diverter helps disperse heavier flows of rainwater over a wider space of your gutter to lessen the chance of the water running over your gutter. It does this by keeping most of the organic debris from piling up on top of the gutter guard. A typical location where a rainwater diverter would be installed is on an inside miter (roof valley intersection).
Your professional installer will be able to determine if a rainwater diverter is recommended for your site conditions.
