When the architects at the Harris Partnership, Manchester, were designing the new Aldi supermarket store for the historic market town of Knutsford, they knew natural slate would be a fitting covering to match to the existing 17th and 18th century listed buildings on the high street. They therefore contacted Stoneleaf Slates for technical assistance on the roofing of a low 23 degree pitch which forms a large part of the roofscape.
The Stoneleaf Celtic Grey was selected to not only provide a traditional looking finish but also due to the flexibility from the quarry to produce the 500×300 slates at the right headlap required for the low pitch, to ensure a watertight roof was installed.
Complete Roofing Systems were appointed as the roofing contractor and were happy working with the Celtic Grey slates. In speaking with both the site manager and the new store manager for Aldi, it seems this is another successful installation of Stoneleaf roofing slates.
