We had the leaf guard gutters, the genuine article, installed on our house, and while they haven't clogged yet, just as much water runs off the front of them as goes down them. We have a drip ridge on the ground around our house now.
Maybe they should come with a french drain system too.
When they were installed, the installer scratched every piece, so they had to redo the complete job. Also ruined the flashing we just had installed where we have a bump-out section on the front of the house. I didn't realize they had done that until I noticed rot where the water is now running down and behind trim boards. Will have to repair due to inferior installation of gutters.
After dealing with the company in Mankato MN that installed and scratched first set, I'll just fix the rot myself.
Not worth the hassle dealing with them again,and corp not willing to listen or help. I would not recommend this system to anyone at this point.
