Did your galvanized/zinc roof moss strip kill plants?
I'm considering installing a zinc or galvanized strip on my roof peak to control moss on the asphalt shingles.
I am concerned the runoff will kill plant leaves under the roof dripline.
Any experience with using moss strips safely?
(I have used potassium salts previously, and the runoff killed vegetation within days. I want to be sure metal strips won't cause a chronic problem like this.)
Thanks a bunch for your advice.
