The Bill Baker Amphitheatre is covered by a roof that was furnished and installed by Novum. The roof features a Pegram spaceframe truss covered by PVC architectural fabric. The membrane is stretched over hemispherical discs above the nodes of the spaceframe structure. PVC, with a performance enhancing coating, was selected as the roof material because of its flexibility and durability. The 53 ft. wide roof is sloped for drainage and spans 78ft.
