LeafGuard gutters worked fine for about 3 years. Then I noticed one dounspout was not draining any water after a rain.
A peek inside the gutter revealed it was clogged with pine needles. If you have any pine trees nearby, they will definalely cause the gutter to clog in time. The bottome line is, they will not work in areas where pine trees are near the house. I have not tried to unclog the downspout yet.
Don't know what is involved in doing so.
Will probably have to call in a professional to get it unclogged. I suspect other downspouts will be clogged soon.
