Wondering how long a Zinc Protect strip will last on your roof? It's designed to fight off discoloration and decay from moss, algae, fungus, and mold, and the manufacturer claims it can protect your roof for over 20 years thanks to its 99.9% pure zinc makeup.

The way it works is pretty simple. When rainwater flows over the zinc strip, it creates zinc carbonate, which helps keep those pesky organisms from taking over your roof.

Now, our research shows a mix of results. Some folks see great success, especially in shadowy spots where moss loves to grow. We came across one person who had good results in the Pacific Northwest—which is notorious for its dampness.

On the flip side, there are reports where people didn’t notice much difference even after six months, like with a shed installation. It seems that the outcome can depend a lot on factors like how the roof is set up, the climate, or how well the strip was installed.

Speaking of setup, a lot of people say putting these strips on is pretty straightforward. You just nail them in place, but do make sure you're getting the right length to cover the needed space—any mismatch could affect how well they work.

Lastly, there are a few mentions of rust, which is odd since zinc is supposed to resist corrosion. So keep an eye on how environmental conditions might impact it, especially if your roof is shaded and more prone to moss.

It might not hurt to look into other anti-moss ideas as a backup.

In the end, while the Zinc Protect strip has the potential for long-lasting protection and is fairly easy to install, your mileage might vary based on the specific situation with your roof and how you install it.
