When a person uses an extension ladder it is imperative that the extension ladder is placed securely against the structure so that it will not sway from side to side or tip to prevent personal injury to the person who is standing on the ladder. The device will permit the use of an extension ladder as originally intended, but will also provide additional surface area that is placed on the roof surface to insure greater stability to the ladder. The device will be attached to an extension ladder and will self-adjust as the extension ladder is placed on the roof of the structure.
