Here is a review of the LeafGuard gutter filter system as provided by a real owner. Sounds like another argument for the cheapest possible Do-it-Yourself gutter guard system.
I had a very bad experience with LeafGuard. The gutters never worked proberly ! Rather than fixing them, the company blamed it on my roof. Eight different contractors said that my roof was not to blame, that the gutters were improperly installed. They need to be removed and put on correctly. The summer rains found water coming over the gutters as well as between the fascia and the gutter, as well as under the shingles, making a wet deck. This has caused the fascia to rot. In the winter, the water which was always pushed up under the shingles,summer and winter, froze. The ice dams melted slowly on warmer days, putting water on the sidewalks and at night this froze, so I had ice on the walks at my exits. It was a complete nightmare.
The company just stalled and wouldn’t answer most of my calls. I tried to work with them on a solution, but they just blamed the roof. When I thought that we had an agreement, they refused to put anything in writing. I gave up in dispair and disgust. I finally had to take them to small claims court where I won a judgment against them. Now, I can find a good contractor to remove and replace the gutters.
Customer service appears to be a foreign concept for them.
