Flashings, gutters, slates, chimneys and glass lantern were observed from the roof valley. No serious faults were evident, but the entire building suffers due to neglect of the perimeter gutters and rones, which have had no maintenance for more that 10 years, going by the build up of sediment, grass and thriving trees in them. Similarly, the central valley gutter around the glass lantern has been allowed to overflow due to blockage of the 4 internal rones around its perimeter, causing some internal damage.

A comprehensive overhaul of the slates, flashings, lantern, gutters and all rainwater conductors is absolutely essential for the survival of the building fabric, together with annual planned maintenance of these aspects.
