Gutter Cap's patented design incorporates the principle of water surface tension in which rainwater adheres to the dome of the cap while leaves and debris fall off the roof. Most of the debris is blown off by the wind. The remainder of debris is pushed off by the rain, while the water flows into the gutters. The existing gutters become a free-flowing roof drainage system, eliminating the hassle and danger of cleaning gutters, and preventing thousands of dollars in damage each year.
