I purchased the Leaf Guard Gutter System from American Leaf Guard of Weschester County NY in December 2002. Since they installed them on my 90' long ranch, I have had water infiltration into the house both winter and summer. In the winter, I have had icicles up to 5' long hanging from the gutters making my house look like an ice palace! American Leaf Guard will not return my phone calls. I plan to remove them before winter and replace them with conventional gutters.
