They are right, nothing enters the gutters, not even the rain. Once the screen gets covered with debris it stays and clogs the screen.
No good with the smaller type pine needdles. Not good where valleys meet. Service call, they blame everything on your roof. I asked " why did you install it if my roof isn't right".
The answer," we are not trained in how the roof is put on". Have an excuse for everything.
A bad product and I would not recomend to anyone. I was taken.....
