(Note: You will need 1 RPG or 2, just in case you don't make it with the first RPG)
When you spawn go to start Menu and look at the map, go to the far left and when your there look behind you, you will see a hole in the wall, go into that building and go to that hole on the second floor.
Jump onto the hole and don't fall off, run jump onto the wooden bar on the left side of the Hole (it's tricky). Now move to the left and jump onto the corner of the Wooden Window Ledge. When you are on it look towards the wooden window and jump to the right then jump onto the middle of the yellow sheet on your left.
When your up face down at the ground (not the yellow sheet) and pull out your RPG and aim but don't shoot, then jump up then shoot your RPG. You should be on the roof, now turn around and stand on the brown wooden bar behind you then turn to your right, then run jump onto the Black Thin Coat Hanger and steady yourself.
Now turn to your left and walk along the invisible wall (note : There's a line on the floor walk along that you will not fall ).
When you have walked along jump down and then jump onto floor. Enjoy!
