BioAdvanced 2-in-1 Moss and Algae Killer and Cleaner for Lawns, Roofs, Patios, Decks, and More, Ready-to-Spray, 32 oz

I used this on this tree right before I went to work. You can see the side I didn’t treat to see if I could tell a difference. It’s completely dead! I also used it on my concrete and roof. There is a shady spot on my roof that started to grow moss. I sprayed it today as well. I’m sure it worked the same on the roof. It was pretty bad in all areas. So it will take a few treatments I’m sure. I had no clue that this was a thing. I was so worried about what to do. This product was easy to use. It has a smell but it’s not supposed to smell like nothing. The sprayer could be better but did the job. If you’re like me. A homeowner but can’t afford to pay someone to help keep your house and property free of things that could cause major issues. Then this is the easy way to do it and so much cheaper! I’d definitely recommend!!
