Rated 1.0 out of 5.0 by unhappy terrible product
I bought the double product premixed spray to make it easier to apply to the roof. I also bought one bottle of the concentrate to wash the house. While it was easier than mixing it doesn't matter because it made things look worse. Take a look at the picture. Awful results. It looks worse now than before i washed the house. I tried to upload a second picture but wasn't allowed. I washed the exterior as well and that looks worse too! Save your money.

Rated 1.0 out of 5.0 by Paul A waste of time and of money
If you have a lot of time and money to waste than this is the product for you. I bought and used more than I needed to cover my roof. After months there is NO difference, you would never know that the roof was treated with anything. If there was a way to put this useless product back in the bottles I would do it and return it.

Rated 2.0 out of 5.0 by king Didn't work for me
Purchased four (4) containers for a 1483SF roof. I only applied to east and south side that had mold, etc. I sprayed enough until the entire area I covered looked like it was a snow covered roof. That was seven (7) month ago. Rainfall has been plentiful. The roof looks partially clean in spots. It did not work for me. I had a small amount left that I saved. I recently returned it to Home Depot who refunded the purchase. I cannot recommend.

It looks like the Spray and Forget I purchased is doing it's job removing the algae from the roof shingles; however, the algae has not completely disappeared from the shingles. It may be worthwhile to note that we've only had one period of rain since I treated the shingles but the algae is being removed. Hopefully, whenever we get more rain, the algae will be totally removed.
Would also like to mention that when the product arrived one of the bottles was half full. When I called Home Depot to ask that they provide a replacement bottle for the bottle that was not full, when I received the replacement, the manufacturer had shipped two bottles instead of one. Thank you, Home Depot!

Rated 5.0 out of 5.0 by MrProject Great for getting rid of mildew and moss
I've battled mildew growing on my roof for several years, as well as black growth on my driveway. This product really worked. The mildew on the roof turned brown and flaked off, the driveway is looking better - and it killed the moss growing in the cracks of my driveway. I just ordered 2 more bottles.

Application was easy..to early to tell if it worked. Coverage was about what the product said....time will tell if it works as advertised.
