Roof valleys can cause excessive rainwater and debris build up creating challenges for gutters and gutter guards. Our rainwater diverters hold debris back and away from the gutter allowing water to flow through more freely. Our rainwater diverters are perforated with small holes to allow for even more distribution of water, and are designed to disperse water over a wider area of your gutter. Concerned about voiding your roof warranty? Simply attach the diverter with an exterior adhesive.
