I have leaves, etc. that are constantly getting into the gutters. Is there anything out there that really works other than a ladder and my hand reaching in to unclog the downspout? I have seen all of the gutter cover type things. A contractor that did some other work on my house says none of them really work...espacially in a downpour. Yes, I know...cut all of the trees down!
I did see a product called Rain Tube. It is like perforated sewer tile laying in the gutter. But very costly. It still required some cleaning off.
I haave tried those little round screen things that you put into the downspout, but they still get covered up with leaves.
