The event originated as a "no-notice hospitality check" in flying units, where pilots proceeded to a commander's residence to check their ability to entertain the group with beverages, food, and entertainment.
Members proceed directly to their squadron mate's house and stomp on the roof in an attempt to be let in.
Originally these events were intended as surprises, but more frequently now, the member's significant other is notified to prepare and make necessary arrangements for the gathering.
According to Greg Tims: Traditionally, a roof stomp is where you greet a new commander or celebrate some sort of special occasion by climbing up on the commander's roof and begin to make a LOT of noise while others are outside banging on the windows and doors.
When he or she opens the door, the commander invites the group in for food and drink.
