Pros: A classic example of the inner city zombie hideout: Only a few entrances, which means it's easy to defend; tough enough to withstand a full-on zombie assault; a great view of the surroundings (which will most likely be ash and rubble, but perhaps the occasional rescue helicopter as well). And you'll always know what time it is.
Cons: Few escape routes. If the ground entrances are swarming with the undead, you can only go up. Once you're on the roof, that's it.
