Lilly Miller Moss Out! For Roofs And Structures Dry Formula 6 Pounds

Used in 1600 sq ft roof, killed the moss after a week or two with rain, handle on container makes for easy spreading. Followed it with zinc roll on both sides of pitched roof. Watch your step up there.

This is the only product we have found to be effective on our roof moss. Zinc strips act as preventive, but this killed the existing moss. Living underneath oak trees here, moss is inevitable.

AIt did good job. I used three on my rambler. Roof looks great.

This product is an excellent cost effective way to control roofing or other structural moss on those surface areas. Easy to use where you can just sprinkle it on at the apex of your roof tops and then just let nature go to work. Really a cost effective value and a wonderful solution for mold issues. Estimates of results takes a few weeks and can have a lasting long term durability depending on environmental factors. Found these offered here at a better price than at the local big box hardware store, great value for that DIY maintenance fix!

excellent product... I have an area that gets very little sun, and moss is constantly there..... but this product helps me keep the moss under control, and eliminates the damp odor I sometimes have... I'm never without this product....

I really wanted to find a zinc based liquid for this moss eradication but since I couldn't I thought I would settle for this. I really needed to apply it with a sprayer as sprinkling the granules seems very impractical for my roof and patio. NOTE: these granules do NOT dissolve easily in cold water! In my first attempt, I mixed them into cold water too fast and they literally turned into large clumps hard as rock!. I spent the next 30 minutes smashing them up and vigorously mixing them into the water solution - but not very successfully. My sprayer nozzle clogged in the first 10 seconds of spraying because of the undissolved granules in the mixture. I ended up taking the nozzle off and got the first gallon+ spread around. In my second attempt I used BOILING hot water - MUCH better results in getting the granules to dissolve. I only had to clear the sprayer nozzle twice. This zinc based product definitely killed the moss so I would give it four stars if not for the granules which I would have expected to dissolve much easier in water. The instructions are a little unfriendly when they talk about mixing "pounds" of granules into gallons of water. I also thought the product was a little expensive but I will pay to get good results.

Usually products work just "OK". I was blown away at how well this product destroyed the moss all over my driveway. It absolutely works. The moss just turned brown and disappeared. Just an amazing product.

Good product be sure to apply on a wet morning when there’s dew on the roof.
