When the rain water passes over the copper flashing, a little copper gets mixed into the rain.
Which acts as a poison to the moss
and algae. The copper will change color to a green-like grey, but that’s a lot better looking than all that moss and algae!
The trick is to put the flashing under the tab of the shingle as far up the roof as you can. You can use a roofing tar and a few nails about every 32 inches apart. Making sure the flashing lays as flat as it can.
It’s always a good idea to run it the total length of the roof, why not, you’re up there anyway.
Besides copper, you can use zinc coated flashing but it may be harder to find in the stores. All flashing can be found at any home center.

Could you send me the name of the super duper roof cleaner you used in the video.What strip works better copper or zinc for killing and preventing moss?
Thanks, Dan Christopherson
The cleaner comes from Roof Sparkle.com however right now as of 7/2011 they are able to legally ship it via mail.
Either copper or zinc works good for preventing it but will not kill anything you have already. That would need to be cleaned first.
Does having moss on your roof damage the roof? Thanks.
Yes. Chances are once you have moss you have already lessen the life of your roof.
Will the liquid pool shock clean moss as well or will I need another process? Thanks.
Yes, you will have to repeat and then help the moss off the roof with a light brush or even by hand. The important thing is you kill the moss.
