Slate supplied: SIGA 120 Random Diminishing Slate

Underwood House, Craigie is a 19th century Grade B listed residential property in Dundonald Ayrshire. The private property was purchased in 2017 and the current owners sought to undertake a full refurbishment to the four-storey home with cellar.

The 500m2 pitched roof features a half turret with six dormers and sweeping/curved valley details. It had been refurbished over time and the property was habitable. However, as an extension had been built, the property was tiled in two types of Welsh slate, which in turn, didn’t provide the desired uniform appearance of traditional Scottish Ballachulish slate, as is used in vernacular architecture of the area.

After discussions with Historic Environmental Scotland (HES), the architects specified SIGA 120 random diminishing slate from SIG’s 120 Excellence range as it is now widely considered as a credible alternative to some historic Scottish quarries, and as such, has been used on many listed buildings. It also provides a readily-available alternative to long-discontinued domestic British slates.

The Excellence range a close match for texture, colour and size to Ballachulish Slate, without the slightest compromise on quality; a superlative quality stone with very low wastage. It comes with a 75-year extended warranty when fitted in line with BS 5534 code of practice for Slating and Tiling.

UK Roofing Award winning, DM Roofing (DMR) of Kilmarnock which specialises in listed and historic buildings was chosen by main contractors, G Middleton of East Kilbride for the full refurbishment of all roofs to the property. SIG Roofing’s Linwood branch supplied the materials to site.
