Over a year and a half ago I had Leaf Filter install their product on my house including a new eave trough on the front of my house. I have had problems with leaves building upon the eave trough they installed going up on the roof. The company has been called twice before to fix the problem, but when I called this time I was told there would be a charge. I said that I thought it was a lifetime guarantee, but was told "only the first year, you should have read the fine print." Now I am out $100 for paying another company to realign the eave trough.
