Aluminum and steel, like most metals, are conductive of electricity and it seems metal would attract lighting, but no - nothing 'attracts' lightning. Lightning occurs on too large of a scale to be influenced by small objects on the ground, including metal objects.
The location of the thunderstorm overhead alone determines where lightning will hit the ground. A lightning bolt that is several miles long, generated by a cloud that is more than 6 to 10 miles high, is not going to be influenced by your jewelry, or even your house. The truth is, a metal roof is no more or less likely to get struck by lightning.
There are many myths about lightning that have been accepted as common knowledge for centuries. New discoveries and evidence has proved many of these false, although many myths are still widely propagated through news media.
