we have a small shed and a 2 car garage in the woods, the shingles are covered with green moss. other than that they are in good condition. with limited tools. I have a sp2 backpack sprayer Model# 01SPO504-1 to apply. have sprayed Chlorine with before to clean my house shingles. my questions are how to kill and remove the moss? I assume by what i've read i would use copper sulphate. if so how much do i mix into 4 gals of water? when i spray it on do i just leave it or is it rinsed off? and where do i get this stuff? then after a couple week i was thinking of applying the cleaner, least time i mixed Chlorine/water 50/50 and added a spoon full of TSP for every 2 galons. and rinse the roof after 20 minutes. is this the correct way to do this or am i way off base? any feedback would be greatly appreciated.
