Can this roof be saved?

Don't walk, run and laugh the whole way! He should make his wife stand out in the yard with a sandwich board that says " I used a cheap no tallent hack to clean my roof! I should have listened to my husband!" and the no tallent assclown that did that job should have to stand out there for a week 10 hrs a day wearing a sandwich board that says " I am the uninsured no tallent assclown that ruined this roof!" just my .02 cents
 
I would leave this job alone unless business was slow, which it is not now. You would lose by making less profit by taking the time to learn how to fix a problem in the busy season rather than concentrate on making money. We are seasonal.
 
I agree with Kory leave that mess alone and laugh at him for letting is cheap wife cause this mess on his roof.Like the other post said he is looking for a scapegoat good people like us dont eat briars.
 
I might have climbed up there to see it closer. Running away is the easiest and likely the best thing to do in this case. I would say if the rain doesn't take it away you might not want to mess with it. I have done some testing with cal hypo and it has all washed away.
 
Run and don't look back. How's that saying go "Fool me once shame on you. Fool me twice shame on me" They hired a low ball hack and left you hanging and now they want you to try and fix there mess because your probably a nice guy who aims to please.. Forget it. You'll feel used wasting your time with that disaster.

We take on some hack mess when it comes to wood restoration or concrete cleaning at times but even on those we get used sometimes because all they really wanted was another estimate for there insurance claims..
 
You made a good choice.

I would let them deal with the contractor that made the mess, you never know what they used up there and without that knowledge and a msds, you could cause a bad reaction that could be harmful/deadly and probably cause damage to the shingles, you just never know.

It is better to be safe than sorry and keep yourself healthy.

John has some good points about being used, you just never know what the real situation is, there is a good chance that you were being setup to take a huge fall.
 
1. Obviously looks like a pump up sprayer was used. The low volume caused thinly treated areas and not all of the GM was removed.
2. Pump sprayer would not had sufficiently dissolved the CH.
3. No surfactant was used to keep the CH in suspension.
4. There was a start and stop treatment approach that caused the CH to dry in inconsistent layers.
5. The CH was over mixed trying to get the % of available bleach up for an instant clean.

Looks to me that since the homeowner readily had a sample in hand that the home owner got cheap and did it him self. Then he was so embarrassed by the result that he tried to blame it on another contractor. Do nothing to the roof. Give it a few rains. Then take a pic and post it here again to show if it came off naturally or not. I bet the home owner got on some BB and lurked thinking he was now a roof cleaning expert and tried it him self.

Yes, the homeowner believed some stupid BS about calcium hypochlorite being suitable for cleaning when everyone knows what a gigantic disaster it is in reality.
Don't fall for internet con men, people.
