Working for a client yesterday, I saw a type of gutter installation I
hadn't seen before, and was wondering if someone here knew about it. It
consists of metal gutters that are completely covered with a fine screen
on top to keep debris out. The screen is sloped towards the roof edge.
Inside the gutter is a layer with bigger perforations in it. It looks as
if this would pretty much make gutter maintenance (i.e., cleaning stuff
out of them) a thing of the past. Stuff just slides off the screen.
