Trinity Slate - A Heritage Alternative
“Trinity” slates are so named in Australia because they are quarried near Trinity Bay in Newfoundland, Canada. They are a Cambrian slate similar in colour to Welsh Penrhyn and of the same geological era; detailed analysis indicates there are also similarities in their chemical and mechanical profiles.
The standard slates are 508x254mm in size and 4 – 6mm in thickness. Officially they are described as “heather” in colour and are a purple slate with a slight reddish or plum hue. They have been used widely in for roof restoration work on heritage buildings over the last 10-15 years and are performing exceptionally well. Photographs of buildings with trinity slate roofs can be seen in Case Studies - Slate Roof Heritage section.
