at all. After we cut bunch trees around the house, the condition of the
roof became much better.
if you want to dyi, just apply bleach or roof cleaner and let mother nature
do the rinsing for you. It took us at least 6 months to get rid off all of
the moss on the roof.
if you want fast result, you may brush the moss while it is wet, but make
sure presoak the affected area at least 7 days before you brush the area.
