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?

Make sure if you negotiate the zinc, or copper, algae/moss preventative strips in your rreroofing job it really is zinc. And the roofers really put it up. And correctly. A big delay in my roof job has hit when the zinc didn't show up with my paid for materials. Then the roofer saying he'd put it up later!
I think he will have it by Tuesday and am paying an expert to watch them for that and other promised things included in price. They knew I'd not be up on the roof watching them,.
I live in Portland OR in a late 70's kind of contemporary home with some large areas and small areas of roof facing east and west. I have concrete tiles that started out with a clay coating on them, but that is another story. 2 years ago, after cleaning the roof of all dirt and moss, I put zinc strips from Home Depot on the highest spot of all areas. It did not work in any area. I was just up on the roof, and moss has grown into all the abutments between the tiles and on the front of every tile run across the roof. We get a lot of rain and very little sun for 6 months so it is asking a lot. I'm off to buy something to spray. Argh.
