I have lots of moss growing on my roof. I wish to deal with the problem permanently. The solution I would like to use is to fit copper strips onto the ridge of the roof to create a weak copper solution when it rains as this will kill and prevent moss. However I also collect rainwater to use on the garden. So, my question is will the copper in the rainwater have a detrimental affect on the garden when I use it to water plants etc?
