1.0 out of 5 stars[UPDATE Nov] It doesn't work. [It makes it worse... yes, really]
Reviewed in the United States 🇺🇸 on October 11, 2020
[Update Nov] It has been 80 days, tropical storms and a hurricane have come through, the untreated and treated areas are exactly the same. The
treated area that went through the above and then I power washed looks worse than the area I did not treat and just power washed. See photo. Amazon made it right and refunded my money.
[/Update Nov]
[Update Oct]
It actually sealed in the mildew / algae and now the power washed can't get it off. I'm adding photos. FOR THE LOVE OF ALL THAT IS GOOD... DO. NOT. BUY!!! This is after 30 days, two applications, and multiple Florida tropical storms... No change. I have been taking picture
regularly with a control area that has not been treated on the west side of my house. The manufacturer states it _could_ take up to 60 - 180 days... [doubt]
[/Update]
TLDR; Barrel tile roof in Florida, power washed most of one side, then used this on the remainder. I followed the instructions and used the standard mix, no change. Repeated with max mix, no change. Power washed the rest of the roof.
Living in Florida with a barrel tile roof and an HOA is fun. Thank goodness for Florida Man to keep us entertained. I power washed the front (east) and most of the north side before running out of gas. My neighbor suggested this stuff so I thought sure, good time to try it. I bought two 1 gallon jugs and a backpack sprayer. I mixed at the standard rate and applied to un-power washed area of the north side leaving a control area. It did not rain for a day and then we had a few days of typical downpours. No change. I mixed up to the max rate and treated the area again. It didn't rain for three days, then again downpours for a few days. Still no change. I power washed the rest of the roof that was not treated. I really wanted it to work, power washing a roof is not fun... letting the west side work for a little longer to see if it does work eventually.

Removes stains. Does not remove moss.
I bought this exact product from Home Depot in June of 2019 to remove bright green moss growth on the north side of my roof, mostly because the before and after pictures on the product label attached to the bottle clearly show that's what it's for. And, within 48 hours of application, the moss turned brown. Great! Unfortunately, that's all that happened. Nine months later, Feb. 2020, that ugly brown growth is still attached to my shingles, as firmly as ever. Now, I'm thinking that I'll have to power wash it off, which is what I should have done in the first place! This product does remove mildew stain (that I didn't even realize was there), but it does NOT remove moss growth. The before and after pictures attached to the product label clearly indicate that it should, but as my own pictures show, that's not been my experience.

Works as described
Sprayed it on & forgot it. Within 2-3 days, mildew, moss, and stains were gone or killed. Heavy moss on roof died & used a push broom to brush it off. Used a garden sprayer with recommended dilution to apply it.

Forget what?
Doesn't seem to clean the driveway but did kill the moss. Will it wash off later. After a week it looks bad.

I've used the pre-mmix solution that hooks up to a hose and that worked great. With the gallon, after following instructions to the letter, and even adding a little extra which the instructions said could be done, didn't do the job. I would not recommend the gallon, and the premix gets expensive. So I'm back to Jomax and bleach. That I know works...

No to the large container
I don't like the 5 gallon container as there is a lot of waste when trying to transfer it into a smaller, usable container. I wanted some one gallon containers at the time but there wasn't any available. I won't buy the larger container again.

I have used this excellent product for a number of years. I am in Georgia in the woods and the roof is mainly in the shade. Mold grows easily and even moss. I need a treatment about every two years to keep the shingles clean. As the directions tell you it does takes some time to see the results.
