From the Syracuse.com article in post 3005:
Sala said the roof will be inverted when it’s brought down. Concrete weights will be brought inside to hold the roof from flopping. The roof doesn’t get any closer than about 30 feet to the floor when it’s collapsed, Sala said.
“It’ll be exactly as you see it, just the opposite way,” Sala said.
“Once the roof comes down, a contractor will remove the roof from the frame,” Sala said. “Right now it’s clamped into a framing system. They’ll cut it and take it off. It will come down when they do that.”
Sala said the Teflon-coated fiberglass structure will be removed within eight hours.Part of the roof will remain on the ground to protect the existing floor during the project, Sala said. Other pieces will be kept in storage before being shipped out for reuse.
