Rated 5.0 out of 5.0 by MikeVancouverWA This really works...what more can I say. I've used it for a few years now and I wouldn't even consider getting rid of moss on my driveway and roof with any other product.

Rated 5.0 out of 5.0 by TC Easy to use...will update with results...
I have a shed in the backyard and some tree limbs overhang its roof. There got to be a decent amount of moss on the shingles of the shed and I was looking for an easy way to kill and remove the moss. This product was easy to mix in a standard household sprayer and simple to apply. I used the 5 parts water to 1 part concentration mixture since, as you can see in the before pictures, I had a significant amount of moss to dispatch. The mixture wasn't much thicker than water and had no trouble reaching the peak of the roof of the shed using a one-gallon, $15 Roundup sprayer (which I highly recommend) while standing on a ladder to the side of the shed.
I just applied Spray & Forget yesterday so can't comment on its effectiveness just yet. I'll update my review in a few weeks with some after pictures and to see if my rating needs to be changed. As far as the ease of use, it doesn't get much easier than this.

We normally use bleach to kill mildew on our roof line and gutters and also on the screen enclosure over the pool. This year we decided to try this product instead. My wife carefully followed the instructions, especially the recommendation to wet all vegetation down before using and then rinsing all plants afterward. Two days after applying this product, any plants and grass that came in contact with it had white spots, dropped their leaves or simply died. This product is the best herbicide I have ever used. I am hoping my plants will eventually come back and the new sod that was damaged will regrow, but my hopes are not high. Our Hawaiian plumeria tree managed to survive twenty years of Florida "cold" snaps, but was no match for this product and quickly shed all of its leaves.
As to the mold: most of the black mold was quickly eliminated, but there is still green mold that has not yet been eliminated after two weeks. Bottom line: this may be fine if you have no plants around your house, and the warning regarding plant damage needs to be much more emphatic. It smells awful, too. So next time: good old cheap bleach.

This product does work but it needs to say that heavy or severe build up must first be removed or lessened to a point where this product and do its job to finish cleaning and maintaining

Rated 5.0 out of 5.0 by Jeff Great for paver driveways
I can't comment on roof use. My driveway is 1700+ SF of paver bricks that collect mold, dirt, etc. I used to have them pressure washed each year for several hundred dollars. Then I heard about Spray and Forget.
I sprayed the whole driveway and the results are outstanding! The accumulated stuff went away. It takes time, however, it isn't instant. But over several weeks, the pavers cleared. I did use several coats on some trouble areas. The best thing is that the mold and other black stuff doesn't return! What a terrific product.

Rated 5.0 out of 5.0 by Bighouse Does what it advertised.
I was suspect as to how effective this product would be, however this product worked superbly. It killed the moss quickly. It is a great product. I would recommend it to anyone trying to get rid of moss on your roof.

Rated 1.0 out of 5.0 by cw Terrible product, waste of money
Use vinegar and water it works much better. I did half of my roof with Spray & Forget and the other half with vinegar and water. The vinegar and water side worked fairly well in just a day. After 30 days the Spray & Forget side was still covered with moss so I did another application. Looks like I will need a third application, so I will just go back to the vinegar and water and get it done. This product is expensive and does not work well. My suggestion- use vinegar and water.

Rated 1.0 out of 5.0 by OldDiyer Fiberglass awning did not work
Used on fiberglass awning that has some tree cover. Mechanically cleaned algae and lichen before applying this product at maximum concentration that is suggested. After about six weeks I see lichen returning. Product did not work for me ans was a waste of money. Maybe others will have better luck.
