I use a cheap bleach all the time to take green slime off ashphalt, pavers, potplants etc. Each Autumn, I lose the sun in my courtyards and all pavers, ashphalt etc takes on a green tinge. I used to use a great product called 30 Seconds (in Australia) and I could smell it had a strong bleach smell so I thought I would buy the cheapest bleach I could and try spraying tht instead - and it worked! Just spray it on and leave. You can rinse it off if you want after the mold has gone but in Australia we in drought conditions so I don't do this any more. If it doesn't come off enough first time just do it again. I also to it on the wooden seats and retainer walls and it doesn not seem to hurt them at all. I use one of those pressure sprayers that you fill up and pump the air out of and then spray thru a hose. The bleach doesn't seem to hurt any plants it comes in contact with although I am careful to avoid them if I can. It takes the green and black mold off but not ingrained stains. Just be careful of what you are wearing when you do it as the tiniest amount of bleach on your clothes and they are wrecked. I have found that the better quality of the bleach, the better it works. Also, it doesn't get rid of it for good. I usually have to do it 2 0r 3 times a year.
bleach will dry the shingles out.there really isnt anything you can use to clean them,the mold will grow back quickly.the proper kind of shingles have to be used to prevent mold.
How To Clean Asphalt Shingle Roofs





Roof Cleaning can be a very dangerous task for the typical homeowner. Spraying a solution on your roof, then rinsing your roof will make your shingles very slick, and in just a blink of an eye, your foot could slip sending you down to the ground with serious injuries, or God forbid losing your life.





Some homeowners however like to tackle projects on their own. Many projects are easy to do, while some are difficult. On a scale from 1 to 10, 10 being the hardest task to accomplish, I would say cleaning stains from roof shingles is off the chart, and the majority of that is due to the safety issues involved.





With that being said, we are going to share with you a simple solution that will remove the streaks off your roof, and tell you how to apply this roof cleaning solution for the average homeowner.





First, you will need the following: a 2 gallon sprayer, a box of Tri Sodium Phosphate (the red box usually bought at Lowes or Home Depot), 10 gallons of sodium hypochlorite, at least fifty feet of garden hose, a garden sprayer, and a protection mask with cartridges to protect your lungs from breathing the solution. You will also need a good sturdy ladder, and also a helper.





First, you will need to hose off all your plants, and give them a heavy coat of water. This solution can damage and burn bushes, flowers, plants, etc. So make sure you give everything a good coat of water first, and while you are cleaning the roof, your helper will continue rinsing off all plants.





Second is mixing the solution we talked about above. Dissolve ½ cup of the tsp in hot water. Fill your 2 gallon sprayer with 1 ¼ gallons of water and ¾ of Sodium Hypochlorite. Pour in your tsp solution and mix well. You can add a squirt of household dish soap as well.





Third, apply this solution to your roof. Make sure you are wearing your protective mask at all times and also protective eyewear. Many times a gust of wind will blow up, blowing the solution into your eyes. You want to always be able to see on the roof. Apply this solution starting at the gutter line, about a ten foot wide section at a time. You will need to coat the entire roof where you have roof stains for the roof to come out even-looking. One 2 gallon container should cover 100-150 sq ft. On a 2000 sq ft. roof you will need several refills to complete the task. Make sure while you are coating the roof your helper continues to water down all plants. You would need your helper to also water down any surface besides the roof this solution comes in contact with.





Fourth, once you see your stains disappearing or turning brown, it is time to rinse the roof. Using the hose your helper was using and a garden sprayer, rinse your roof really well. The shingles will be extremely wet now, so be very careful in your movements.





Finally, once you have finished rinsing the roof, check to see if you have successfully removed all the stains. If not, repeat the process just for the stained area. If you have removed all the stains, then congratulations, you have successfully removed black stains from your shingled roof.

What is causing the algae on your roof ?





New shingles are prone to serious attack by algae, moss and black stains. Shingle formulas have changed to include extenders like limestone, cellulose and various wood products. Less and less petroleum and felt ingredients are now used. The unexpected result is an increase in destructive algae infestation (black or green shingle stains) on millions of homes all across America. The stains also attack wood shakes and clay tile roof material. Shingle manufacturers did not intentionally create this side effect. However, moss, algae, and fungus are now consuming and decomposing your shingles, just as a fallen tree is decomposed in the forest. Both are nutritious plant food. Shingle formulas will not be changing back to the other stuff (non-algae food). After significant testing and research, we discovered a safe and effective cure. Successful treatment involves understanding the cause of the problem, not just splashing chemicals on the roof. Equally challenging is that algae are able to flourish on shingles as we stand helpless on the ground. Once Shingle Renew has treated your roof no other work is required. Rain will finish the rinsing process for you. The rapid rinse process can be used for immediate results.





Moss, algae and fungus decompose shingles, wood shakes and clay tile, just as they do fallen trees. Algae, moss and fungus are not harmless. They are destructive and cost home owners millions in unnecessary water leaks and roof replacements. They even reduce the value and appeal of your home. One could argue that primitive algae are stealing from you. The look of most shingles after a few short years in service is disgraceful. Investing thousands in a new roof can actually make your home look worse, not better!





What does the leading shingle manufacturer say about this new eyesore?





“Mold and mildew are functions of environmental conditions and are not manufacturing defects. As such, mold and mildew are not covered by this warranty or any implied warranty” Sorry homeowner, but you’re on your own.





If your roof is damaged prematurely by this type of growth, don’t look to the manufacturer for help. You would know this had you read your shingle warranty carefully. This pointless destruction is easy to prevent, and very affordable. Especially when compared to the rising cost of a new roof. At first glance, roof stains seem harmless enough. Not true. They are a very serious problem. If you already have black streaks or moss, or see it beginning to form contact Shingle Renew for treatment now.More info provided at www.ShingleRenew.com
