Workers removed the copper from the south side of the Study earlier this week. That leaves two sides without copper and two sides still covered. You can see the wooden decking and battens, just like what they found on the east side, before they installed the weatherproof barrier. From their investigation inside the dome, the workers report additional interior steel supports for the wood and copper that make up the roof.
