Hi, i have a customer who wants his conny roof cleaning, it has a yellow coloured stain all over it. I went up on ladders to have a close look, thinking the panels had just all faded and discoloured but on close inspection it looks like it is a build up of something, he has not had it cleaned properly for years.
What would some of you more experienced roof cleaners use?? many thanks

you will not remove the yellow staining , it's down to uv light, usually the whole panel turns yellow, whilst others on same roof are un affected.

The sun has discoloured the pannel by the sounds of it.... only way to fix that is to replace the pannel
