Lilly Miller Moss Out! Roofs Moss Killer Concentrate, Herbicide, 6 lb. (2 Pack)

Product seems to be working already on my roof where the shingles were darkened with a slight greenish tinge. The granules sprinkle on white but are turning a yellowish color in places and the shingles under those areas are restored to their original color! Amazing! I only wish it had come with a sifter type tool os sprinkle device….

Got this at a really good price and it Worked great. Applied in the afternoon, next day the moss and algae was already killed!

If it does what it says it will solve my moss problem on my roof. The product has been applied but not enough time has passed to see results. Product was available, delivered on time and at a reasonable price.

I have used this product twice a year for many years now to prevent moss growth on my roof. It works great! Walmart had the best price beating Amazon. Delivery to my home was free. Keep up the good work.

Purchased new house with a lot of trees over garage. Love the canopy, but was worried about the moss growing on the shingles in the shade. Applied and it's working immediately.

I've been using Moss Out! on my roof twice a year for many years now, and there's not a speck of moss on it. And living in the Great Pacific Northwest where we get more than our fair share of moisture, that's truly saying something. And I can tell you this without so much as a doubt. It's MUCH easier to prevent moss growth than to remove it once it's taken hold.

I had moss on my roof and what this product advocates is true.

The jury is still out. Easy to understand instructions. i used a sprayer. Easy to apply. Too early gor results. Ordering was easy. Delivery was prompt and on time.

This roof moss killer product comes in very small pellet form and at least half of the product rolls off and ends up on the ground below. Lilly Miller did not think though the application on roofs.

I used 10 times that amount directed and it still didn't kill the moss. I used two cans for 1000 square feet. The can doesn't have a sprinkle lid it just dumps out more than you want. That's how I used 10 times the amount. It's likely engineered that way to sell more. I had light rain after spreading it so it was applied as directed. Nothing except lush green moss. See picture.
