I spent last evening and a few hours this day helping a friend dismantle an... awning? I think it'd be called, at their home so they can build a proper entrance, the awning was built by the previous owners, and they were really, really, really afraid of that thing falling down. About 5 torx skrews of varying length every foot. 6 torx screws in each angle iron, and it went on and on. The battery for the screwdriver had to be charged three times... Good stuff.
