Roofing

The existing roofs consist of corrugated sheet metal that appears to be zincalume. There is evidence of timber shingles on a section of verandah roof at the rear of the administration buildings (within the Prison wall). It appears that the original roof was slate, likely to have been of Welsh origin.

SPECIFIC POLICY 51: As roofs reach the end of their usable lives, and subject to further investigation to confirm that shingles or slate were present, consider the replacement of roofs with shingles or slate.

​

SPECIFIC POLICY 52: All roofs should be maintained in good condition including all associated rainwater goods consisting of flashings, gutters and downpipes.

​

SPECIFIC POLICY 53: The downpipes contain baffle shrouds to prevent people climbing them. This detail is unique to the operation of the Prison and should be maintained and reinstated where missing or degraded.

​

SPECIFIC POLICY 54: Continue to paint all external painted rainwater goods using oil or alkyd paints. Avoid the use of epoxy or acrylic paints for metal work. These are not traditional paint systems for metal products.

SPECIFIC ACTION 35: Through regular monitoring, continue to prepare and paint all painted rainwater goods on a regular cycle of 7–10 years.
