Customers want this growth removing from her roof ( the white spots ) she doesn't want it cleaning, just the spots gone, any ideas?

[Smurf]

So she don't want the tiles cleand then really
Just attempting to remove the white lichen would leave the tiles looking all patchy as the tiles are filthy

The customer sounds a right oddball to me and probably thinks it's bird poop...Good luck with that

I would only do it if she had the full roof done.
Soft wash.

Think Algoclear is your best bet.

She did'nt go for it, as smurf said I told her it would look patchy unless we gave it a full clean but the price was too high.

I have been asked to quote four roof cleans, and I didn't get one !    I think people have a low expectation of what they need to have to pay for a professional job 

[Smurf]

Thing is to do a roof clean properly within H&S regs most would not want it done as the price would be astronomical.
That’s why you get idiots walking about on roofs using a pressure washer without any fall protection then they wonder why they get taken to court and fined.

You are very wise for a smurf

I'm on spiced rum tonight  so don't take any notice of my ramblings.

Algoclear Pro does a very good job on roofs. It takes time to work on lichen though.
