Cleaning black algae streaks from roof AMAZING RESULTS!!

Cleaning my asphalt shingle roof using clorox outdoor bleach

You just helped me make $500 bucks in 6 hours. Thanks!

In the future, try to buy non Ammonia based surfactants such as Dawn. To use homeowner grade soap to save a buck, try to use Gain or some type of laundry detergent that doesn't have NH4 in it because it makes a gas when mixed with bleach. Laundry detergent should be even more sticky, allowing the bleach to sit and dwell even longer, making it even more worth your while. Otherwise very savvy work, very impressive sir.

Good job! I bought a bottle of swimming pool algae remover a while back. I already had the pressure washer and the foam cannon. After watching this, I can't wait to try it out. Thanks

I believe foam cannons typically have an output ratio of 1:10, meaning that if you use the strongest bleach available at 12%, then you'd only be getting about 1.2% down on the roof, which is a little on the weak side. Clorox outdoor is about 8%, so you were only putting down about 0.8% bleach, while I believe most softwashers put down closer to 2.5%. Great idea, but this method may not be as affective.

Whatever you do, don't "paint" yourself into a "corner". You don't want to have to walk over the slippery stuff just to get down off the roof. Plan ahead.

That works great. I just ordered a foam cannon off Amazon to use with my pressure washer.

I use wet and forget. A little more expensive but it last for years because it reactivates after every rain.

[stanpeezy]

That actually looks pretty good great job man!!!

[bigbadclan]

did you rinse it down ith ware after? how long does it look foamy for after you applicated it @shawn h

[markcorson]

U could also mix say 20 l of the solution in a tub, leave it on t ground and let the pressure washer suck it up using the other outlet on t pressure washer

[rafaelrosario]

Should’ve gave us a before and after picture of the difference up close

Would love to see more vids of this process that you developed an how you improved it. I love the idea of using a foam cannon as it seems to simplify the process more to my appreciation. Thank you so much for sharing...please update

[paulhester]

Thanks for sharing! Lotsa Great Information.

Hey man, where you get that chemical bottle mixer on end of your pressure washer? I ain't never seen one of them before.

[lzh]

I never thought about foam cannon. I just used it wash my cars. Thx

[TheSouthernSkunk]

What do you think your chemical ratio ended up being?

[truthbetold]

Just as a heads up don't waste your money on outdoor bleach the concentration is the same a normal household bleach at a fraction of the cost. At most you'll have a concentration of 8.25% Sodium Hypochlorite which is what kills the mold and mildew. If it's higher than that percentage then it is considered Chlorine. Honestly the dollar store bleach is just as good at cleaning a roof as the $10 Clorox outdoor bleach for a tenth of the cost. It's shady marketing for the unknowledgeable customer your basically pay more money for the same exact thing that's in the laundry aisle for cheaper.

What about Runoff ? Did the Bleach stain Grass/Plants

[mrsaintlewis]

I going to try this on my house siding.

[SRSnure]

Great idea! Have you tried using this procedure to clean a concrete driveway or brick wall?
