JeffWard 14 Report post Posted June 25, 2007 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.

CALLTODD 15 Report post Posted August 28, 2007 Zink sulfate is a powder and can br purchased at the feed store. Sprinkle it on thick and the moss will be dead in 5 weeks. Zink cloride is available at most any garden type store and can be sprayed on. Mix acording to the lable. 5 weeks also. Bleach tsp borax is also another quick method. but zink is a better maintaince product. Share this post Link to post Share on other sites
Tmrrptr 164 Report post Posted August 31, 2007 That zinc sulphate might be a good ingredient in a rinse, to keep things from coming back... I thought it was interesting when you mentioned results after 5 weeks, or so, when applying the zinc sulphate by sprinkling... HUGE difference in attitude between the great Pacific Northwest and us down here in Socal. These people want it done NOW and expect better than new! r Share this post Link to post Share on other sites

Spraying, caustics, 12% bleach, brighteners etc.from a backpack sprayer is bad news. You can get some nasty burns on your backside. Think about what your chemical is desinged to do, and then , think about what it can do to your skin. .........just the medic in me coming out!!!!!!! Share this post Link to post Share on other sites
Apple Roof Cleaning 202 Report post Posted September 3, 2007 We can do it NOW with Applesauce. But if you live in the trees or near by,gonna need zink every year.(maintaince program) Search out the Hillbilly Roof Treatment thread I started here a while back. In it, there are some ideas about treating a roof. The idea in treating a roof is to be sure there is always some Moss/Algae posion ON the roof. Once rinsed off, most prevention chemicals are almost useless, unless re applied every year. Share this post Link to post Share on other sites
