you sure are 
i meant to ask you guy, what can i use to get the green furry stuff of the roof rubber? dont want to scrub it incase it breaks :/
Green furry stuff? Do you mean mould?
Apply some TFR or APC over the area and agitate with a detail brush.. Then jetwash and it should come straight off.
If you are using a garage forecourt jetwash do not use the brush lance.
You can also apply the same technique to door shuts and around boot and bonnet hinge areas which are another mould and dirt collection point.
