Here are some pictures of the dirtiest roof yet . . . .

My mix was 20 gal 12 %
two big bottles of Ajax
15 gal Water


This thing was NASTY!!!

I sprayed the nasty part first then continued around the roof and applied a second coat to the nasty stuff right before we left. . .


I think it turned out nice. .. .


What do you all think ????



BTW i did NOT rinse this roof i don't rinse any of my roofs . . . saves me time and money . . .

The lichen and algae had actually stared eating away at the granules on the far end of the roof

In this photo the dark spot is actually clean it just has some of the white and green granules missing . . .. it was a pretty good roof for pictures also an awesome roof to educate the HO on . . . they swore up and down it was from the trees and the factories lol

They were very happy with the results!
 
Looking Good there Scrappy doo! I don't rinse to many roofs off either. (whenever possible.)They always come out real nice after a good rain. Mother nature can do in 3-5 minutes what takes us 30-45 minutes.
Good Job! :)
 
Looks real good AJAX? and thats it - I will try this method this weekend - I tried not rinsing today on a roof but for some reason I just cant do it - I had my helper rinse it - gave hime somnthing to do?
 
Good job Scrappy, that roof looks a LOT better now!
 
I will be honest the roof is not going to look brand new when you leave (it wil look clean but will have sorta what i think looks like a glaze over it . . . But i tell the customers this up front when giving them the quote . . . but in less than a week it looks awesome . .. .

Yes ajax i use (2) two quart bottles of the grape fruit with bleach alternative in it . . .


I apply with a delevan 5800 series set up from bob 1/2 inch hose
 
Your "WORST ROOF YET" turned out VERY NICE Scrappy,

A few questions for you if you don't mind.

I did noticed some granular material loss as in some areas the coating materials are almost gone......but you say you don't rinse...ever?

So having said that, then, you did not cause the loss of the silica or granulars as seen in the photos. I am curious, how do you account for all the loss of the granular material? Maybe the last cleaning? Do you know the age of the roof?
Anyway, for a roof that looks as if it is close to 1/2 to 3/4 (10 -18 years) thru its useful life cycle, you definitely gave it a major FACE LIFT.

Scrappy, for the new guy starting out and trying to grasp what your chemical mixture is, and how you deliver the cleaning agents to the roof surface, let me reiterate, if I may, and see if I understand you.

My apologies to you old pros for reducing this to its basics.

Your cleaning mixture-You used 20 gallons of 12% Hydrochloride Solution (Pool type Chlorine) and two bottles of Liquid AJAX Brand Dish washing Soap (the regular, not the ultra concentrate) and you then mixed it in a 35 gallon poly tank with 15 gallons of water at the site as to keep the mix potent. Then you applied it with a chemically resistant, diaphragm pump (DELAVAN 5800) and used a 1/2" chemical resistant clear braided hose to keep your flow rate up while on the roof. Is this your mix and chemical delivery setup? If this is correct, let us know, Scrappy. Also, describe if you waited for a good rain or did it just "magically" turn the roof into the "AFTER" photos.

Scrappy, please explain for the new roof cleaner so they don't think you know some impressive magic tricks. :)

And finally, so I personally understand your cleaning method. Once you apply the cleaning agent, you then, go back over the really heavy algae laden areas for a more complete coverage and then you roll up and go home? So does that mean you just let the rain do the work and come back and take your after photos after a good heavy downpour? let us know also if you apply a fungicide or algaecide afterward (after allowing nature to do the rinsing) or do you just leave the solution on and collect payment?

Thanks Again, Scrappy for sharing your experiences with us.

The HO said it was around 12 yrs old but i must mention there is heavy tree cover over the WHOLE ROOF (note the spotted looking before picture is because the sun was out the after pictures are because it was cloudy) My only consensus with the missing granule is that this roof was in such bad shape it had actually started to deteriorate ??? Chris does that sound possible????

I did this job on a Thursday it rained Fri. and Sat. after pictures where taken on Tuesday of the following week!

Spray-Collect-Come Back take afters and Spot Treat if needed!!! This is the third roof i have got to sign up for a service cleaning for next you . . .just a light coat to keep it from coming back!!!

Thanks Again, Scrappy for sharing your experiences with us.

I recently cleaned a roof with a heavy carpet of moss in certain areas without rinsing. When I returned a few days later to inspect, I noticed that where the moss used to be you could easily notice missing granules. I assume it is from the roots lifting the granules off

DJ "Scrappy",

Great follow up and thanks for your answers to my questions.

I hope they help answer the "mysteries" of cleaning roofs for those who were previously doing some head scratching trying to read between the lines.

Good job again and I and I'm sure others, as well as I, look forward to your progress and more pics and more great things for you! All the Best DJ and Rubber Side Down! (P.S. If your not sure what I mean by rubber side down, just remember when the rubber sides up your probably landing on your a@%!)
 
I have noticed granule loss is due to heavy lichen and moss growth. Once the lichen and moss have attached to the shingles, and after you kill them with chemical they will fall off with the granules that they have attached to.

Chris has mentioned before, once the roof has grown excessive lichen and moss it's a damned if you do damned if you don't job. Granule loss is unavoidable.
