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.
They covered the wooden structure with the rain and snow shield until they get the new copper on (ETA for new copper: next week!). Today they worked near the cupola to remove sealant and other material from around the windows and the joints between the cupola and roof. Even though they’re complying with safety regulations, I am glad they still steady themselves on stable parts of the building while they’re up there!
