Debris is the main reason people consider installing gutter guard protection devices. When trash gets into the gutters of your home it lays there soaking up water and rotting until someone can go up and clean it out. When you install a Gutter Filler gutter guard, only water passes through the Gutter Filler. The water runs through as intended – free of any leaves. Many types of guards will eventually allow trash into the gutters around the edges and through the slots. Gutter Filler gutter guard products never allow trash in and the material’s porous surface allows air to get underneath any debris and dry it out quickly. This debris is exposed to the wind and blows away easily.
