About This Product

For best results, apply Lilly Miller's Moss Out For Roofs and Structures just prior to the time when fall rains begin or in early spring. Moss growth can occur in nearly any location where dampness persists. Such areas include roofs, decks, steps, patios, walks, fence posts, and foundations. Since moisture is essential, most moss growth appears during the fall, some in the winter and in the spring. Very little moss forms in Summertime. Destroying existing moss is done most effectively during times when its growth is most rapid and when rain is not expected for several days. Controlling moss may add months, or years, of service to roofs, patios and such areas.

Highlights

  • Kills moss quickly
  • Non-staining formula can be used on roofs, cedar shakes and composition singles, cedar siding, stucco, wood decks, fences, walks, bricks, stone, sidewalks, driveways and other structural surfaces
  • See results in hours
  • Covers up to 500 sq. ft.
  • Moss Out Complete Moss Control

          Hit or Miss! (20-80%) For me anyway
          Unlike moss out lawn, this one didnt work this time. Used a decade ago and it worked really well, so bought some more and very disappointed, so far. In fairness, done Saturday, but repeated yesterday and still huge areas where the moss is a green and lush as it was on Friday evening! Again coverage much higher than they suggest, which perhaps is an issue with the mixer bottle head that it came with more than product, but I guess at least I have plenty left to go up a 3rd time!!!!!

          I have fairly heavy moss growth on the side of my house and a discoloration on the front. The front faces North and the side West. I sprayed a discolored area on the front and saw no improvement, even though I waited over a week. On the side, the results were better. I sprayed the center block in this picture and you can see the block is brighter and in the bright area there is no discoloration or moss.

          Thought I would get a head start this spring by ordering this early, but spring is really taking it's time getting here this year, so the moss on my roof hasn't started greening yet. Gonna be a while yet for the optimum time to use this...here's what I've figured out in the meantime... This stuff can be applied anytime, best in spring & fall, when actively growing. It works on moss & algae, not sure about lichen. It does warn in the directions to avoid spray & runoff on desirable plants, so be aware. Some other products on the market don't need this warning. This is a concentrate...6.8 oz per gallon water, 54 oz. bottle. Apply liberally, when moss is moist. Apply when frequent rain expected. If rain within 24 hrs., repeat application. Treats 1000 sq. ft. max. Looking at 2 possible application techniques...tank sprayer, or hose-end sprayer...tank is probably more economical & precise, if you don't mind roof-walking (or if it sprays a distance). There was no price listed at the time the Seeds program provided this, so no idea of “value” rating.

          The bottle was leaking when the store associate handed it to me. She put it in a plastic bag but knew full well it was leaking.

          leaking bottle
          I picked up the order today at my local HD. It was in a box. When I opened the box at home the product had leaked from the bottle. Although it was bagged in plastic, it leaked through. All of the important paperwork is unreadable. Whether it was packed at HD or at the manufacturer someone should be notified. I will attempt to find the instructions and cautions online. I hope that it works better than it was packaged.

            Moss Out was needed to clean the moss off of my roof. I’ll be using it on all of my outside brick.
