post your tips on how to get up on rooftops and other buildings.

i look around the building and look for close trees that i can climb and jump on to the building from it. i look for a big pipe leading up to the roof.
and look if a car or van or trailor is parked next to it, so i get up on it and get on to the roof. or i get a friend that has a tall van i can get up on. then i tell him to park near it so i can get up.

here is a pic on how to get up on top that i made:

just use you graffiti mind.
