Zinc strips on roof to help with roof moss (do they work?)
Does anyone have direct experience with using zinc strips on a roof to prevent future moss? We recently treated the moss on our roof with Wet & Forget and while researching came across a product called Stainhandler zinc strips that are applied using clear adhesive caulk. (No nailing into the roof shingles needed.) The adv. says "EPA approved, and long term results (20 year or more protection from fungus, moss, mildew etc.)" I am also wondering if the caulk is likely to hold these strips on our 10 year old roof (other than the moss it is in really great condition) and to keep these strips in place in a rough and tumble country setting. Am I setting myself up for failure and constant re-caulking of them? Also do I place one strip at the top of do I have to place strips every so many feet down the roof. Advice/feedback please?
