The roof comprises a number of structural elements and the oldest, including the main train shed roof Spans 1-3, was built in the 1850’s by I. K. Brunel. Various developments and alterations have been made with the most substantial being the addition of Span 4 train shed roof and the London Street deck in 1916. Span 4 has not been maintained for a significant time, such that it has started to fall into disrepair. A scaffold crash deck has been installed below the majority of the span to protect the station from falling debris. There is a tension fabric canopy below the section of Span 4 over the concourse area.
