In June 2016 Ellis and Co completed an eight month programme of major repairs to the slate and lead roofs.
Special photographic hording was commissioned to give a ‘business as usual’ feel to the building and the works were completed under cover. Two king post trussed roofs with slate coverings sit to the east and west with an expansive flat lead roof in central area over the main entrance.
Leadwork was replaced including moulded details, access hatches and steps. We repaired and reglazed the two lantern rooflights. The slate roof was retiled using original slate where possible.
Uncovering the roofs provided an opportunity to learn more about the construction of this historic building and SKF consulting were appointed review the building phases and inform the further repair work. Throughout the work samples of the materials used were approved by the Rodney Melville and Partners Chartered Architects.
Brick supports for the bearings of the king post trusses were cleaned and consolidated. Ten common rafters that had dropped over the banqueting room were raised and secured. Common joists over the main entrance and decayed rafters on the north end of the roof were supplemented with new treated timber supports. During the works we installed protection to the ceiling of the Banqueting Hall to conserve any loose plasterwork from the original ceiling.
Asbestos roof slates were removed. We installed walkways in the ceiling voids, laid new lead on the roofs including detailed lead steps to the access hatch and introduced fall arrest, lightening conduction and bird management systems. We appointed subcontractors to install PV solar panels and an air conditioning system to manage humidity in the building.
Our joiners repaired and redecorated the decayed rooflights, window cills and sashes and we redecorated the vaulted section of ceiling in the crown court.
