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.

I used the concentrate on my Florida shingle home that was beginning to turn black on the north side. After a couple of months, I could tell a big difference. I'm going to buy a couple of more gallons to finish the whole roof. My neighbor with a clay tile roof mentioned the same and is planning to buy the garden hose sprayer so he doesn't have to climb up onto the tiles.

Rated 1.0 out of 5.0 by Art It may eventually work
Have applied product twice within the last month to the same areas and still have black streaks. It gets just a little better each time. It take four or five applications to clean a small area. Very expensive for the results so far.

I used one of the bottles on the back of my roof. My house is only 1100 sq feet. It started looking yellow, like it was going to kill it, but it didn't. I had to have someone actually go up on my roof and clean it.

The product worked on the North side garage wall and removed the green mold in three days. I will be using it on the roof to remove black streaks and hope that it works as well on those.

Rated 5.0 out of 5.0 by Roger Most effective roof cleaner on the market
I've now used this concentrate version of Spray N' Forget for three years across my entire roof. It is a slow acting product but highly effective in killing moss, algae and other growth on my slate roof. I never thought I would be able to regain the original look of the slate roof after it was nearly covered in moss. Two applications over six months and the roof is now clean and in remarkable condition.

Rated 5.0 out of 5.0 by ciso305 Great product.
I first used the product on my shingle roof over two years ago and it looks like new. When I first applied the product I did not have enough to finish the entire roof. I procrastinated and a few month and when I finally purchased more of the product and got on the roof to spray it I could notice the difference between the treated and untreated areas. This last purchase I did was for my mother's roof which is tile.
I will see if it works as good on tile as it did with shingle.

easy to use but has not seen any difference yet. It has been on for two months I guess I have to give it more time. After a few more month I will review it.
