Diamond slate roofing is a single lap method of slating, often used with terracotta hip and ridge capping. This was the ‘in vogue’ style at the time of the Federation of Australia, and so was called the ‘Federation Style’.
Normally these style roofs were done using asbestos cement, but there is not an effective replacement for the old asbestos shingles in terms of quality and longevity.
The fibre-cement type shingles (either in the rectangle or diamond shape) are no longer available in Australia due to quality problems.
