@FoFa, if you have any limbs hanging over the roof you need to have them cut back. Â It does help prevent a lot of that kind of thing over timeSeems like if you get enough of those, it will just be extra insulation. Â lol
When I first bought my house I had some on my roof before we replaced it. I cleaned them off with a wire grill brush. And then sprayed a little 50/50 bleach water on the area. it seemed to do the trick. 4951
Gosh, I would have cleaned them off before they got that big. Â Who wants ferns growing on their roof? Â But it does look a little better than the 2 inches of black and green mold on my neighbors garage that I have to look at when I am in my backyard... 4951
