Bayonet jump from tree to the north east of the way the guy in the picture is facing.
On the stairs into that building (the back), there is a light near it. Rocket jump from the stairs onto the light and jump onto the roof.
I'm pretty sure they patched the rocket onto lamp, I couldnt land on it and when I did, the roof had a barrier. Maybe I just got unlucky.
