roof moss

**R* P* <r*@richpomerantz.com>**

I've been wrestling with the question of my roof moss for a few years now. I
know there are those who advocate leaving it alone, it looks rustic and
charming, etc etc, and I agree, it does. It also shortens the life of my
roof, and I am unfortunately not in a position to enjoy that kind of luxury,
so I want to remove it. I know power washing is not the answer as it will
certainly damage the asphalt shingles.  I have been told that bleach will
not work. The solution seems to be to use some kind of herbicide to kill it,
then remove it gently with a brush. I am fine with this approach, except I
do not want to use something that will also run off the roof and poison
everything it comes into contact with around the perimeter of my garage and
my studio, the two roofs where I have moss growing.

What does the collective wisdom here suggest?
