In my experience I have only found it to work the first 4' of the roof on moss.

Moss is growing right next to it?

I am not sure they work but I looked at an apartment complex today that has 31 buildings. They hav cleaned 18 of them and put the zink strips on after cleaning. I need to price the cleaning and installing the strips

I was asked about them this week also. Isaac, do you know how long that strip has been up? And is it confirmed that it is the proper strip?

What I think is going on in your pic Isaac is.... If you look about two feet under it doesnt really have moss. That is where the water/zinc goes down and is sucked up by the moss. Above the zic even though its touching the strp the water goes down after it hits the strip. Not sure if you get my drift?

Was installed last year. Not confirmed if it is the proper strip, I see quite a few of these here, and always on the filthiest roof. I liken them to gutter gaurds.....

Ya I got it. It just sucks seeing these all the time, you know?

I put a bid on one roof that the guy had strips every 4' of roof. He had the stripe thing going. It still had moss.

I tell customers all the time that the reason i do not try to sell zinc strips to them after I clean their roof, is because in my experience of 5 years i have never seen zinc or copper strips that work. I add that what they'll pay to have a roofer come and install the strips, they could hire me at least 1 more time maybe twice (averaging $500/per cleaning).

I have never seen a complete success story..as stated earlier maybe the first few feet or so. This is good for us guys..keep cleaning and make money!

I've used them on a few roofs at the customers request but they didn't help much.

They do not work at all here in Tampa, unless you place them every row of shingles!
There was a roof cleaning company here in the Tampa area that installed and guaranteed them called Roof ReNu.
They are long gone, and left a bunch of angry customers. Here are some pics of a filthy roof with Zinc Strips, in case your customers ask. I am not territorial, as long as you are not local, use the roof cleaning pictures to make your case that zinc strips don't work.

The thin roll out kind do not work in Portland Oregon . They might work if we installed them at the ridge then 4 feet down then four more feet down ect until the roof was an ugly mess of zinc strips and nail holes.

Wet and forget can be sprayed on using your chemical injector on your pressure washer. You will be able to treat moss annually to prevent moss growth without getting on the roof. I offer this for a little extra with annual gutter cleaning.

Not too well the best I have seen is about 4 feet from the strip.

I offer this for a little extra with annual gutter cleaning. Suggest you try some Borax or Copper Sulfate vs the Wet and Forget. This is what some use here in Tampa Florida to treat roofs with. That stuff don't work too well on the Tampa Strain of Algae, but we seldom see Moss down here in Tampa.
