Here is an interesting thing I found when I was looking at some gutter guards that I installed a year ago. I was checking out an unrelated gutter problem when I noticed In the middle of a length of gutter, a piece of foam filter had weeds growing out of it. Under further inspection I discovered a network of roots grown through the filter itself. This weed is only growing in one spot which so happens to be over an area of the gutter containing some standing water. This length of gutter is not obtimally pitched so there is some rain water sitting in the middle. This is a very common situation with aluminum gutters.
How did this weed grow? Apparently if you combine sitting water with a gutter foam filter there is the potential of having weeds grow from it.
