roof cleaning?

Has anyone ever cleaned shingles with powdered bleach to remove fungus from shingles? If so I was curious of the results.>>>

My buddy said he uses oxygenated bleach because it doesn't hurt plants, animals, insects, etc... I've never used it though.>>>

Copper, We charge $350.00 a roof. The only cost is the bleach. I really dont see this as a money maker not enough calls for it. Another issue most new shingles are algae resistant.>>>

Nobody has any answers to my questions? My thinking was with a bad economy people may be inclined to spend a little on keeping what they have look good. I'm looking to get into this if I think I can make a buck with little overhead.>>>

Bump>>>

what kind of money can you get for cleaning a roof? And does it last? Are there products you apply to prevent new growths>>>

There is a consise article in Professional Roofing I recieved this morning.>>>

the bleach doesn't do very well at all. i use www.roofshampoo.com you can do about 4,000 a day in cleaning with two guys and 60 dollars in material. but getting the work you kinda gotta hustle for. not breaking the bank with it but its a nice addition. we do maintenance on a couple hundred houses this year is the first year we are going back with this system in our company,.......i am curious how many we can get from that....a lot of them are stained>>>

I think I saw some sort of an accessory that went with a ridge vent made out of zinc. That was for algae, but acid rain and various mat interactions require different remedies....I like that machine someone had , like a floor buffer/ scrubber .... >>>

If you mix the bleach and water in a garden sprayer and then spray the roof with it till it just about starts to run, it will do the trick. The algae will die in short order and the roof will clean up with the rain. The problem is that when the old mold and algae goes away, the holes where the roots were before will allow for more to grow. A vicious cycle. Copper strips will help to keep the algae from starting, but will not do muchg once it has established.>>>

Hi,

Take care with the bleach it might damage shrubbery, plants etc.

How about the old copper strip ?>>>

Thanks, Mike. That product could be interesting in dealing with algae buildup on granulated steel roofs. But I'd really like to know what the ingredients are - sometimes the cure is worse than the disease. :huh:>>>

Always want instant....... jobs not done until results show. How could it be easier than a garden hose ?????????? Bleach at hardware store and water ur done and paid. Next job.>>>

Bleach and water mixed up with a garden hose not too much pressure should do you just fine have done it a bunch The algae does damage the shingles check after the cleaning.>>>

my concern would be biogradeable and harm to plants below, and asphalt and concrete and decks. Citrus sounds good though>>>

Thanks Jed, recently a few homeowners have asked me I dont know what direction to point them in.>>>
