SIGA Natural Slate offers a true alternative to extinct Scottish Slate, preserving Scotland’s roofing heritage.
SIGA 120 is sourced from Welsh quarries and has been designed to be a close match for texture, colour and size to Ballachulish Slate, without the slightest compromise on quality. Approved for use by Historic Scotland on many listed buildings, it is available in a range of sizes to replicate diminishing courses for a beautiful, authentic roof finish.
Scottish Geologist, Dr. Joan Walsh has identified SIGA 120 as a perfect solution to maintain Scottish historic and heritage roof coverings and practices, minimising the impact of foreign imported slates in conservation areas.
The Augustine United Church has recently been re-slated with SIGA 120 restoring the roof to its former glory; creating a stunning outcome which is visually indistinguishable from original Ballachulish slate. For all the details read our Augustine United Church case study.
