its so hard knowing how long it will take being the first one as for hourly rate what should i aim for cheers
It's not for me to tell you how much Mark.
Because it's your first one then you'll have to use it as a learning curve. I understand it's hard for you to estimate the time it will take so I would allow for a bit of breathing space.
Personally, I like to use a detergent, I use none caustic TFR but there's probably a multitude of products available that would be just as good. On the roof I spray it on first with a pump up garden sprayer, then wfp as normal. You don't have to use it but personally I find it makes the job much easier on heavy soiling.
One tip- BE VERY CAREFUL WITH THE FINNIALS!!! (the fancy bit along the peak of the roof apex) They are easily knocked off!
Good luck

There's good money to be made with conservatories.
