You can use bleach and get the same resault if not better. I feel it's safer than what You can use bleach and get the same result if not better. I feel it's safer than what Glenn sells. They are great people and I do feel they are right on with what they do and they are honest. I just feel that sodium hydroxide is too strong to put on a roof. But that is a debate among the different contractors.Glenn sells. They are great people and I do feel they are right on with what they do and they are honest.

I agree with Dan.
While it can be argued that pool chems are pool chems., sterilizing a pool is just one of the many things sodium hypochlorite is used for. Therefore, is chlorine just a pool chem? The answer, no. Is an algecide, just a pool chem? I don't think so.
Renew is sod hydroxide (I think), is that made for roofs. Not exactly, but it is used on them.
Get my point. It's all a matter of preference. Everyone's is different. I have been using New Again Roof and Deck cleaner, supposed to work great on roofs, but I don't use it for that. I have my own choice that I think works great.
Whatever gets the job done, men!

Roof cleaning
Your right it is a matter of opinion, but my customers feel much better when show them I'm using a special chemical thats just for cleaning black roofs. the renew label that says specially formulated for roofs,100% bio degradable. Specialy after the last guy used a harsh bleach recipie and killed all there expensive plants... Dan any chemical you use can be too strong if not used in the right proportion, (bleach or sh)
Frosty if you have a less intrusive formula for roof cl
leaning ,please share it for the whole board to see... zap

My 2 cents:
The manufacturers of s/h products would be sued out of existance if their product was harmful to asphalt shingles. These products are tested/labled and marketed as safe for cleaning roofs...if they weren't, I would be first in line at my attorney's door.
Would I use it for cleaning an asphalt driveway? As with any chemical, only if it is labled for that use.

Suds, I used a little over 1 1/2 gallons of the New Again. One job was as a cleaner on a deck that had never been sealed. Worked fine, neutralized and brightened with oxylic acid.
Second job was on a railroad truss retaining wall. Down-streamed it. Worked very well, although, I think it would work better and I would rather not downstream it and use it in more of a concentration.
Haven't used it on a roof. The instructions on the bottle say to mix at 5-7 to one, apply to roof, and rinse with low PSI. 500 or so PSI.
I like this product as a wood cleaner, and I think that is what I will use it as. I suppose someday when I have the urge--and time--I will try it on a roof and compare it to what I use now.
What I have will last me awhile. I have more chemical stock than I need. Always looking for something better--even when I find something that works. Like to try different things. However, the answer is YES, I would (and will) buy New Again when I run out. Good product.

thanks for all the replies. i just now saw them. for some reason, i didn't get an e-mail telling me there were responses. the "quat" i'm refering to is mentioned in a couple of articles on deck cleaning in powerwash magazine(if that's the name). supposed to kill the spores, which i'm told are generally not eliminated by chlorine or sh. i think it's intended for use after another chemical(bleach, sh) has killed the mildew or fungus growth.
in any event, i've learned that i was misinformed about the composition of the shingles. they are actually asbestos shingles, which i assume are no longer used in new construction but are apparently available for restoration of pre-existing asbestos roofs.
the house is literally in the woods about 75' uphill from a creek(which, incidently, is home to the vermillian darter, an endangered species). wild hydrangas(sp?) and dogwood trees, among other indiginous vegitation, surround the house and would be directly hit by the run-off from the roof.
i'm aware of the environmental issues (which is why i'm going to try the quat first) and the on-going debate about which chemical is less environmentally hostile. what i don't know is anything about asbestos shingles--whether they might be damaged by certain chemicals, how much pressure they can withstand, whether the process of cleaning them release asbestos into the air in dangerous amounts, and so forth. some of the shingles have been replaced recently, but most are original to the house, which was built in the late 1930's.
i've told the owner that i would do the job only if i satisfied myself--after consulting with my experts (the members of this bullitin bourd)--that i didn't run any risk of damaging the roof or creating a dangerous situation.
i look forward to getting yall's thoughts.

ps another problem, and the subject of a different thread, is that the water supply available is only about 3.5 gpm's, and the manual on my 4 gpm washer says it requires 5 gpm's.

new again will not harm the driveway. we spray it on p/w off. black top , concrete, patio stone, brick walks, stucco . we even do barbecue grills .(i tell them to heat the grill like you would a stove before using and wipe off the rack). i would like to ask a question does anyone have a dollar amount you want to get for machine hour?
