How Our Patented Rain Gutter System Works Gutter Helmet® has a field-proven and time-tested design that uses surface tension and gravity to keep rainwater flowing through your gutters, while keeping debris and gunk out. Where the Water Goes Gutter Helmet has a textured surface that allows rainwater to cling to it as the water flows downward and into the gutter channel. Did you know that the highest recorded amount of rainfall in the U.S. is 11 inches per hour? With the ability to handle 22 inches of rain per hour without overflowing, Gutter Helmet proves it has the ability to handle even more than nature can throw your way. Where the Debris Goes Gutter Helmet also has a curved edge that extends past the edge of the gutter. Once rainwater rounds the edge of the gutter cover, it passes through a slit that is only 3/8” wide. This stops debris from getting into your gutters. Twigs, leaves and other clog-causing debris are simply swept off the surface and fall to the ground. This unique design has made our gutter protection system America’s #1 choice for over 35 years, with millions of feet of gutter covers installed and a nationwide dealer network serving more than 30 states.
