Anybody know what could cause this, or how to fix it? Do I just need to re wash it?

It is hard to tell from the pics Josh, but it looks like the reddish colored shingles have less granules on them!
The Granules are what determines the color of the shingles, and if they are gone, it will greatly effect the way the shingles look.
Has this roof ever been cleaned before, and if so, was it pressure washed ?
 
Happened again. You guys sure I'm not doing something wrong? PM is pretty pissed.

Wow! That looks terrible!
I am beginning to wonder if it is not a bad interaction between the Roof Snot and the Fresh Wash ?
I know some people who just use one of those products, or the other, at a time.

We switched to the Liquid Gain Dishsoap a few years back Josh, and clean many many roofs in the Tampa Florida area, 6 days a week, w/o any of this happening.

I also need to ask, are you putting out a decent spray pattern Josh ?
 
20 gallons SH 45 gallons water, 32 oz Fresh Wash, 32 oz Roof Snot.

Ah Ha! I missed this, the first time!
I believe this may be your problem!
WHO the*** told you to use this much of those things ?
Your solution is only 65 Gallons !
ONE 16 oz bottle of Liquid Gain Dishsoap would have been more then enough soap.

Well, Roof Snot is recommended 32 ounce per 50 gallons. Most people recommend one ounce per gallon of mix with fresh wash. It didn't seem to make much of a difference though, so I just added half the normal amount of fresh wash instead of adding another 10 ounces of Roof Snot.

Well, I suggest you start by using what Larry Millette and I use, since we both clean a TON of roofs here in Florida.
Then, see if you have any problems (we don't).
Be SURE and get all that stuff out of your hose and tanks, because something sure ain't right.
I know Roof Snot and Fresh Wash to both be ok products to use for roof cleaning by themselves, maybe combined together, aint good ?
 
I see those patterns on roof's over here in Palm Coast Fl and I have been assuming when the housing boom occurred here the contractors were grabbing shingles from where ever they could find them and they were slightly different color...but hey I'm sure they got paid.....
 
To me its clear as day that either the roofer screwed up the install and put up two different colors of shingles or the shingle manufacturer lacked quality control on their colors. I see that exact pattern on brand new roofs from time to time and very often on patch repairs.

I have seen that too, but on BOTH roofs he provided pictures for ?
Have you looked at all the pictures in this thread ?
There are 2 roofs in question, a brown one, and a blue/gray one.
There is a problem on both roofs he has cleaned, and that would indicate to me that he (something he did) is the problem.
In fact, the Property Manager said they have never had this problem on one of the roofs, and it had been cleaned before.

If that's the case though, I just don't know what the problem could be. I have heard of plenty of people mixing Roof Snot and Fresh Wash with no problem at all. In fact I have used that same mix on a few other roofs with no problem.

Well, it is really weird, with 2 roofs, having the same problem.
LOL, unless a bad roofer is alive and well, up in Ocala

That is a possibility I certainly would not rule out.

LOL, me either, it seems that "anything goes" up there in Ocala! That entire are grew so freaking fast because of The Villages, that good help was very hard to find, especially help that spoke English!
Now you come along, clean the roof, and they can see the crappy job that the black algae hid!

I once did some condos full of senior citizens. The painters spilled some solvent on the shingles, the algae grew over the streaks caused by the solvent, we cleaned it, and we became "the bad guys" !
They actually took us to court, but they LOST !
 
If it was because of something you did I seriously doubt that it would be so razor straight. You say you have used the same exact mix with other roofs and no problem, if thats the case just those two facts would rule out anything you did.
 
Hey Chris & Larry..... In going back a few years there was some major storm action in that area if memory serves me right. and those look like a repair to me. Being in the roofing biz for about 30 years it seems that the repair was done with an alternate shingle color. The discoloration pattern looks like the image showing wind damage.
Learn some roofing installation basics is a big benefit it helps with these issues. My final thought is the roof was repaired from wind damage, color was not matched and algae grew and now is cleaned revealing to a new owner the real roof.. But I could be wrong.

My questions are:
How long has the owner owned the home?
If a length of time was there a repair done? from storm or hurricane, tornado wind damage?
Check the slot lines to see if the color splits between shingles.
Learn some roofing installation info and this should help you be more educated about what your cleaning as well as the cleaning.
Here is a picture shingles blown off and the pattern

Good point Randy. Josh, look the property up on the property appraiser web site for your area. Any roofing repairs or new roofing work should show up. Most likely on the bottom of the page where they had to pull permits. I know it shows up on the Pinellas County property appraiser site that I use.

Hello Kim! There are different 2 roofs in this thread, have u seen both of them ?
I wonder what Randy, your roofer husband thinks, and I know you have been around roofing for many many years.
Check out the Tan Shingle roof pic he posted, see what you and Randy think ?
 
Ah gotcha Chris didn't see the second one.. But I would say that is a miscode in the dye lot when the shingles were installed.. I can take some pics up her in the north of roofs not cleaned ever and it will show the same thing. Definitely a miscode I will grab some pics and post them..
The thing is when installing the shingle, some companys pay no attention to the dye lot coming from the supplier, the supplier in turn cares less what the contractor gets, halfway through the install oops... colors are showing different, some will be more obvious then others depending on the color. We always insist that our order comes from one lot , never mixed. as a couple guys had mentioned in the heyday of slapping shingles on from fast builds to storm damage, the supplys were low and this is what very well could have happened. Will post some miscodes later today...
BTW We are shooting into Fl this week, got a few lined up to do. down there. maybe grab a lunch if the time allows your schedules.
