If there's one key to the clog-free performance of the LeafGuard system, it may be the way its design leverages the principle of liquid adhesion. Here’s how it works: When rainfall cascades down the roof and reaches the curved hood of the gutter, it flows right around the lip and into the trough. Meanwhile, when debris comes into contact with the hood, it gets deflected to the ground. With leaves, twigs, and pine needles unable to enter, the gutter remains unobstructed at all times, ensuring the free flow of water all the way to the downspouts and away from your home. That's why you never need to clean LeafGuard gutters: They don't get dirty in the first place!
