I have had great success on very consistent cleaning of HIGHLY SOILED ROOF TILES...
I put this down to my recent purchase of a foaming apparatus for the end of my hose...works like a charm...
I pump my regular mix from my tank but in my foaming pot I have a high alkaline detergent which has a small amount of caustic as well as a very thick and highly foaming bleach component...
This foaming gun is putting my mix on roofing tiles in a most beautiful foam which significantly enhances its dwell times meaning I am having not spotty cleans...i.e. The ridges of tiles are not requiring a second coat...
Its fantastic and also enjoyable to watch...
My foaming gun is called a Hydo Foamer and only cost me 100 aussie dollar...its made up of mainly plastic and seems to hold up quite well against the chemicals...

WASH N WOW Non-Pressure Roof Cleaning "We do the WASH, you do the WOW"
You and I think alike, our roofs are differant to shingle roofs that are rough, gravelly and hold water and have grip to walk on, our roofs are tile & tin that are very slippery when wet and water runs off them like water off a ducks back, In another life I was an Electrician and have been on a lot of roofs in my time, and nearly fell of a few due to wet mold, slime or light rain. I am glad to see the foam thing works for you, I was thinking about going down the same road, I even thought about using just a commercial foamer machine, no pumps, no batteries and depending on the situation no mixing as the proper foamers have chemical proportioners, just drop the chem hose into the SH / surfactant concentrate mix, connect water hose (may be a compressor) and foam away, change the ratio of the mix simply by turning a knob from 5% to 50% depending on the job. I'm also glad to see that you are getting work for roof cleaning, are you having trouble getting people to do it, or are they happy to know that it can be done, cheap

Also while you are there, i have been searching for that Amonyxly Lo or what ever they call it and have found 2 places here in Oz that sell simular stuff Vicchem in Melbourne sell Vicamox 401- Lauryl Dimethyl Amine Oxide and this place in Sydney http://www.albright.com.au/products/industrial/gardiquat-obau/ sells a simular stuff it's about $2 to $3 per Kg (they sell chemicals by weight even liquids) I have some samples on the way and will let you know how they go. Cheers.
Wonder how often you have to fill the container during a cleaning? I'm all ears on this one. Like you say Chris, may we can all learn something.
I was thinking the same, BUT, remember, it is only soap in there. so ya just carry the gallon of surfactant up therte, and re fill, I guess ? I guess the question is How long does the soap in cannister last ? Blowing Bubbles, a little soap goes a long way, LOL
A little concerned that ya can't see what is going on, under the foam, and it will make tile roof slippery ?
fellas i will post some pictures of it in action...got a commercial job next week where im going to use it..
the thing is im using a very thick bleach and caustic foaming detergent i get from my chem supplier...doesnt even weaken the mix so it works a charm...
it lasts a longgggg time...my foaming pot is 2.8 L and the foaming attachment sucks only a tiny amount from the pot at a time...because the stuff i put in it is a high foaming detergent it doesnt use much because a small amount does a longgggg way
ill post the brand and name of it when i post the pics...
hey martin from aussie!
yeh mate roofs downunder are very prone to run off...without the right solution a lot of waste is incurred...martin you come across many glazed terracotta tiles that were put up in the 20's and 30's post world world?? now they are a challenge!!

Yeah, I remeber blowing bubbles, the mix lasted a long time. There are several high foaming bleach compatable detergent formulations commercially for sale, or we freaking rool our own ? Wow, that pretty cool, most foamers have a small hose to suck suds from. This is basically a hose end sprayer, huh ? I wrote to the company for literature a few days ago. This looks real cool!
It would help clean because it keeps the mix on the roof and not on the ground giving more contact time. yes it is just bubbles, but if you think about it like layers, the first contact covers the roof then as the bubbles disolve an other layer comes in to contact with the roof and so on, SH stays active for about 15 minutes so if you could keep it on the roof for 15 min then it would be doing it's thing for longer, Run off is wasted SH and dose nothing to clean anything apart from frying worms in the ground, This is my line of thinking any way.
upstreaming like in pressure washing and real foaming from foaming equipment are two differant things, do not confuse them. the whole idea of foam is to allow longer chemical contact times that is why foamers were invented. foam generally only last minutes depending on what you use
I guess I understand it in theory, but not in practice. SH is so damn aggressive, I can't believe it matters that much. I would think that a drop of pure love would be more powerful than a foam bubble of love.

Roof Washing Exterior House Cleaning Grand Rapids, MI
It is ALL about dwell time guys. The more dwell time, assuming the chemical is still active, the better you can clean, and with less total chemical. The less total chemical used, the less potential damage to our earth. And, the less our COST to clean a roof.
However, the better it sticks to a roof, the better it sticks to plants/pets
I saw an Aussie Dingo with a face full of roof cleaning foam running the outback, blind! He answered to the name of "Lucky" LOL
i suppose why some of you dont understand the foam theory is because we are probably talking about totally different roof types...
In the US i know you guys encounter mainly shingle roofs...over in Australia its mainly tile and they are really soiled...
Ive done the tests...Ive sprayed normal apple cider on the roof and yes it does clean most stuff off, in my experience though, on heavily soiled roofs the ridges of the tile are still very dirty...
The concept is to create a foam which enhances the dwell time giving the chemical more chance to work as chris was saying

I wasn't going to say anything more about foaming but if you look at this video (which is not realy a good example of foaming) http://www.youtube.com/watch?v=gkYG9HYqdQg but you will see with a real foamer you can adjust the foam level from a "wet" foam to a "dry" foam and every combernation in between, real foamers will shoot 25 to 30 feet the same as a fatboy. the foamer in the video is a foammaster 890 in OZ they cost around $650 complete in the USA they would be around $300 complete. Lafferty make the best foamers, eg. Lafferty HV foamer in the USA complete with hose and wond $450 in Australia the same unit is a whopping $1,800!!!!!! http://www.youtube.com/watch?v=7uVvWplg7DU I want to say when I in perticular talk about foamers our roofs are 90% tile roofs the rest are colourbond steel roofs, as such we refer to foamers for TILE & TIN ROOFS I can count the number of shingle roofs I have seen in my life time on one hand, and ALL of our roofs have gutters.
