Gutter Caps

A gutter cap is a smooth piece of curved, painted metal installed over the top of the gutter to keep out leaves and other debris. When it rains, water flows down the roof directly onto the cap. The water clings to the cap’s surface as it flows over it. The cap’s design draws the water down, around, and under the cap and into the gutter; leaves and other debris, which do not adhere to the cap’s surface, fall to the ground. A number of gutter caps and one-piece gutters with built-in caps are on the market. All these products operate on the same basic principle. Gutter caps are sometimes less effective in an area of the roof with a steep valley. Unless diverters or other correcting devices are installed, the large amount of water flowing down the valley during a heavy rain can overshoot the gutters. Since this issue is specific to individual roof design, seek advice from a competent gutter contractor.
