2.67 in. x 50 ft. Zinc Moss and Mildew Preventer Strip is rated 4.4 out of 5 by 11.
Rated 5 out of 5 by from easy to use I had been looking all over for this. Actually more than I need but could not find at other stores at all.

Rated 5 out of 5 by from Very easy to install Installed under the ridge tiles on moss covered barn roof. It appears to have an immediate effect on eliminating the moss growth, but will have to have more rainy days to determine the total benefits. It's alot easier than trying to balance some 5 gals buckets of bleach on the roof ridge.

Rated 4 out of 5 by from Easy to install! The zinc strip rolled out without problem and maintained its shape throughout installation without crimping. Looks good; much better than a roof with heavy moss and mildew build-up which I had before!
