INSTALLING ZINC STRIP MOSS AND MILDEW PREVENTER
How zinc strip works. Zinc strip does not kill moss or mildew, it inhibits their growth so that in most cases roof cleaning is reduced or eliminated. The zinc strip is installed along both sides of the ridge of the roof, so that most of the strip is exposed. The exposed zinc will oxidize, forming zinc oxide. Every time it rains, some of this zinc oxide leaches down the roof, inhibiting the growth of moss and mildew.
Very large roofs may require extra protection. If the roof extends for more than 14 feet, down from the ridge where the zinc strip is installed, regrowth may reoccur. In these cases installing a second zinc strip about halfway down the slope may be required.
The roof must be cleaned of moss and/or mildew. Zinc strip will help control the growth of moss and mildew, it will not remove growth that is already there.
Zinc strip can be used on composition shingles, wood shakes, and tile roofs. Note however, that it is not as effective when used on barrel tile type roofs as the fungus inhibiting action remains mainly in the valleys of the tiles.
Only areas below the strip will receive protection. On hip roofs, this means that for full coverage, each side of each hip needs to have zinc strip applied.
If regrowth is a continuing problem, it may indicate another problem, such as inadequate attic ventilation, which is supplying moisture that encourages mildew or moss growth.
COMPOSITION AND WOOD SHAKES
1. Install zinc strip on both sides of the ridge
2. Install under the cap shingle on both sides of the ridge. Do not insert more than 1” under shingles.
3. Use roofing nails with neoprene washers, spaced 12” apart. Nails are best located under the covering shingle.
4. If you prefer, the zinc strip can be glued, using a high grade, exterior construction adhesive.

Rated 4.3 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by 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. September 22, 2015
Rated 5.0 out of 5.0 by Excellent The zinc moss strip was ordered for a free energy science project. So happy that though it was not at the local Home Depot, I was able to order online and it was there within 4 days. Excellent service - much appreciated/ and product as described. December 8, 2015
Rated 4.0 out of 5.0 by 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! September 29, 2015
Rated 3.0 out of 5.0 by zinc flashing Just installed so no results yet as to if it works. Was easy to unroll and slip under top row of shingles. Less expensive here than with Amazon! August 12, 2015
Rated 3.0 out of 5.0 by Good but a little wider would be great! If this. We're 1 inch wider it would be great. As it is it is a little finicky putting down. Definitely need mastque and foam sealing nails. The low profile makes it vertually inviable though. Time will tell how it works. I did take off the heavy moss with a wooden paint stearer and used "wet it and forget it" to get ahead of it. September 23, 2014
Rated 5.0 out of 5.0 by very nice item the metel was firm and had nice support . open easy and very easy to install. would do it aginge last time i need was soon. thje support was nice and quick time. would purchase agine lickly. October 7, 2014
Rated 5.0 out of 5.0 by Zinc strips Too early to tell results installed pieces in rafters of an upper deck to stp algae on lower deck. October 21, 2014
Rated 4.0 out of 5.0 by Looks like what I expected for a Zinc roll strip So far looks good but I will not know for a year how effective it is. October 22, 2014
