The act of gaining access and exploring roofs, both flat and angled in nature.
1. Take the elevator to the top floor, and then the stairs to the very top level. Many times, buildings will have roof access via stairs that go past the top floor to a door that leads directly to the roof, or a vertical ladder that leads straight up to a roof hatch.
2. Look for windows of top-floor or lower-level offices, bathrooms, or laboratories that may open up onto the roof.
3. If at a construction site, use ladders that may be laying around to prop up against existing structures to access higher areas.
Tips on rooftopping: * If climbing on a shingled roof, look for surfaces with angles to each other like this:
see the valley flashing? it's easier to climb up a roof with hands and feet at angles to each other than climbing straight up the side. * Gutters may be unstable. test your weight to see if they'll hold before trusting them entirely. * Doors in stairwells may lock behind you. Check to make sure they don't before you are forced to walk all the way down to the bottom level. * You can also take an old hotel room card with some double sided tape or putty on it and stick that inside the door jam so that a door can't close behind you. That way a door will close fully, but the latch cannot lock the door and trap you in a stairwell. [shotgun mario's tip]
Things to bring: * Medical tape or duct tape (to tape open the locks of doors for future access) * Door stop * Flashlight
If climbing shingled or angled roofs * Shoes with traction * Gloves (but usually bare hands work well) * Rope * Camera (if there's a particularly lovely view)
Be wary of: * Turning on or waving around flashlights on roofs, especially at night - they are highly visible if in a highly populated area * Making a lot of noise.
