    I've cleaned many, many conservatory roofs without issue, however, I have a roof to clean that's an absolute mare.
    Its polycarbonate that's overhung by trees and the sheets are literally black.
    I've done it twice before. Once using a karcher pressure washer (I know), and once using a strong mix of virosol. Both times took me forever and my shoulders took a pounding. Neither times left a great finish, although the customer was happy.
    So what I'm wondering, is how would using hypo work out? Your opinions or ideas please on what mix or if its a bad idea.

    I think many people on here talk about hypo and don't know enough about it. Proceed with caution.

    First what is the 'black' stuff?

    Second, have you googled it to see if there is something less nasty to remove it?

    Lastly, conservatory ladder, bucket of hot water and heavy flash floor cleaner and scrubbing brush.

    Good luck with it.

    Maybe try whats been suggested before, spray with Algon a week before you clean it, supposed to help break down algae n stuff? Maybe wont work, Ive never tried it.

    There are two sides to this roof and the side facing the trees is much worse. So the black stuff is something to do with the trees.

    Have you ever used it for pre-treatment of gutters?

    :eek::eek: Mother of God! :eek::eek:

    I have never seen one like that.. Holy Birch trees Batman!

    That looks like a coating that is perishing, not dirt piling up.

    I would go with a heavy bleach mix, key being to keep it wet at all times, and keep it moving.

    Wet the roof, apply bleach, agitate, wait 5 mins, repeat and then again and again.

    Only do 4 - 5 panels a time as you don't want them to dry.

    This is a job that I fear is all labor, no shortcut here. I hope you billed well, I would be asking at least a day & half to know I have time to finish it well.

    Good luck.
