1 week after installation, water POURED on to my deck at a valley. A guy did come out and said it was a "rookie installation error" and drilled some holes and solved the problem. Not sure why he figured the error was only on 1 of the roof's valleys.
a month or so later, water was flowing over the gutters, called and a fellow called back and told me to pressure wash the gutters.
I did all that and the gutters are still overflowing with water flowing onto my foundation. I called again and no one ever bothered to call back.
THOUSANDS of dollars for an inferior system that was apparently installed wrong. I do have videos.
Review about: Leafguard Gutter Installation.
Reason of review: Bad quality.
Monetary Loss: $6000.
Preferred solution: perhaps correct the installation to correct problem.
