Roofing Slate In Australia
Natural slate roofing has become increasingly in demand for quality contemporary and restoration work. The most commonly available slates are listed below.
Australia's traditional Heritage slate, PENRHYN is the slate by which others are judged. Originally shipped to Australia in the early 1800's as ballast, Welsh PENRHYN slate roofing has stood the test of time on such landmark buildings as the Sydney Town Hall, St. Mary's Cathedral, Kirribilli House and Phillip Street Barracks. PENRHYN remains the traditional burgundy-grey in colour (also known as Heather Blue/Purple or Blue Bangor).
This slate provides not only unique aesthetic advantages in terms of colour, character and beauty, but also durability and longevity of performance proven over centuries of use both overseas and in Australia. PENRHYN is used extensively for period restoration work, but also for quality contemporary projects.
Cupa are the highest quality Spanish slates available and their appeal can be demonstrated on such distinctive buildings as St. Mary's Cathedral Presbytery and the Australian Golf Club, Kensington. Unlike other Spanish slates, CUPA is supplied with a 30 year performance guarantee and is increasingly in demand for quality domestic and commercial projects. CUPA is classic Spanish Charcoal in colour.

During this time they have proved their durability and unfading colour in conditions ranging from the severe winters of Canada to the variable summers of Australia (e.g. ANZ Bank Collins Street, Melbourne).
South Africa's unique Mazista Silver Blue roofing slate is now available in Australia. Mazista have been producing slate roofing since 1927 and have won a reputation for adaptability and durability in both Europe and the United States.
As a general guide, the labour cost for slate roofing is approximately $80 per metre for a typical slate roof. This price would usually include timber battens, sarking and ridge capping (e.g. lead, copper, colorbond etc.) The size and complexity of the roof may have a bearing on the final labour cost.
