We did a few gutter clean outs today and one in Jefferson was really bad. I don’t think the gutters had ever been cleaned out. Leaves decay over time and turn into basically black soil. It is just like compost. That is not something you want sitting inside your gutters.
If you do your own gutter clean outs I would suggest getting some gutter guards if the house is 2 stories. They don’t work perfectly but they keep the vast majority of leaves out of the gutters.
