Gutters that leak are gutters that give storm water the chance to do damage. Even drips and drabs of water can compromise exterior paint or rot wood trim. Fortunately, with LeafGuard there's no way for water to escape once it enters the gutters. That's because, in a class of its own, LeafGuard provides the only drainage solution that's 100 percent seamless, with no flimsy connections for water to sneak through. Another big advantage: Whereas the installation of many two-piece gutter guards requires altering roof shingles, often in violation of their warranties, the seamless, one-piece design of the LeafGuard system enables it to sidestep that headache altogether.
