Rated 1.0 out of 5.0 by Bobss So far not good
It has been several weeks since the product was applied...with no results. Every instruction was followed. In fairness the directions do state to allow up to six months for desired results. Additionally, there has been only a minimum amount of rain. If results are achieved at a later date, an effort will be made to update this review.

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.

This is described as slow acting product so we will see. The first bottle worked very well during application. The second didn't mix well for some reason and required constant shaking. I am not very confident at his point

I was looking for a product that would get rid of the black mold/mildew on my roof and siding. I wanted a hose end sprayer because I did not want to get on the roof. This product sprays at a far distance, so I could spray onto my ranch house roof from the ground. Sprayer works great.

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.

Rated 5.0 out of 5.0 by Andycap Great roof cleaner
I went with the hose end sprayer because of the high roof. I had used the product before where I had to mix the cleaner with water and use a pump sprayer but I couldn't reach the upper section of the roof. The improvement in the look of the roof is amazing.Just give it the time to work.
