I must agree with the other complaint-comment on the Leaf Filter gutter system.
If you have numerous deciduous, pines or cedar trees and get the typical tree debris build up, I sure wouldn't recommend Leaf-Filter! All that stuff sits and doesn't blow off on the next windy day. It gets embedded in the "surgical micro-mesh screen" and grows moss!
True, the gutters don't clog, as the water cascades right over the gutter-cover and onto the area below.
I have to use my "gutter brush" and from a wheelchair, cruise around the entire house and sweep off the gutter cover!
