Rated 5.0 out of 5.0 by ChrisNJ Totally works, even on siding - which doesn't get much rain
One of the best purchases ever - super simple, and it actually works.
I followed the directions including: spraying plants, grass, bushes, BEFORE and AFTER application.
I used two whole bottles and throughly soaked the areas which really needed it.
Its only been about 1.5 months during the summer - so some light rain, but not a whole lot. And the pictures will speak for themselves.... complete change. There is some slight residue left - so I'll try maybe spraying it off myself.
HomeDepot only allows 6 pics max - but you'll get the point.
But overall, very very happy with the results.

Rated 5.0 out of 5.0 by Lady Great product
Being surrounded by trees my roof doesn't get enough sunlight so the moss thrive on the shingles, I also have black streaking on the shingles. Last spring I used Spray and Forget for the first time. After being sprayed it showed no signs of improvement, but mixed with the natural elements over a period of time the moss is gone as well as the black streaking, the roof looks like new. It was so easy to apply by just hooking to the hose and spraying. I chose to apply it on a warm dry day with no rain in sight. I bought a new supply this year to do over the garage, as it saved my roof from further damage. Even though it is a little pricey it was far cheaper than hiring a crew to do the same job

Rated 5.0 out of 5.0 by Jerry Very Very satisfied !
I Had some pretty nasty stains on my roof.I did not know what they where. After some research I learned that they were letchen mold that it actualy eats the shingles. Not only did it look bad but I had two contractors tell me I needed a new roof and this one is only five years old.
Being finacialiy challenged, I began searching for an alternate solution. I found Spray and Forget at my favorite store the Home Depot and liked the reviews. I thought it might be a waste of money but its still cheaper than a new roof.
It did take a few months to work. I applied It in early June and by the first of September the stains are so negligible you can hardly see them and its still working ! It did kill the grass around the down spouts from the rain run off but O Well.
I would like to apply another application next year in the spring but I might not need it.
Thanks for saving my roof !!!

Get rid if those black streaks on your roof....just spray and forget....just like the product says. I have used this product several times with outstanding results! It does cost a bit but you will be satisfied with the results. I am!

Rated 4.0 out of 5.0 by CentralPennsylvania Almost Ideal
Spray & Forget 32 oz. Super Concentrated Non-Refillable Roof and Exterior Surface Cleaner with Hose Sprayer is an almost ideal solution for roof moss, lichen and wind-blown algae that causes black streaks on asphalt shingles.
Application is easy. Desired results for roof moss appear in about a week. Desired results for lichen and wind-blown algae occur over many months in conjunction with rain.
Spray & Forget delivers positive results, but is not 100% effective. Sometimes a second application is required, and depending upon the environmental conditions in your area, reapplication is required every 12 - 18 months.
Spray & Forget Super Concentrated Non-Refillable Roof and Exterior Surface Cleaner is not inexpensive, but it is considerably less expensive than the costs associated with repairing asphalt shingles and roofs due to damage caused by roof moss, lichen and wind-blown algae.

Not exactly spray and forget, but after it's sprayed and left on for a while the muck comes off pretty easily with a low setting on a pressure washer. Easier job with than without. Definitely worth a try.

Rated 1.0 out of 5.0 by NeilH31 Didn't work for us!
We tried this on our roof, used both bottles and followed the directions completely. We waited the 6 months as the bottle stated and the stains are still on the roof. I have before and after pictures to prove this and will be sending to the company asking for a refund. Long story short, this product didn't work for us and we are out $70 dollars.

Rated 5.0 out of 5.0 by Houtexan99 Works Great, but takes time!
Does the job, but not for those who want immediate, quick results.
I have a 2,400 sq ft home and the roof was put on in 2001. Dark mold stains started appearing about 8 years ago, and within 2 years of that, was really streaky and ugly.
I used the self mix-up Spray & Forget in May 2014. Didn't notice much in the way of stains disappearing until 8-9 months later. I re-applied in May 2015 using the hose-end sprayer and it was much easier and much quicker. Really can tell the difference now. Stains gone!
