Del Carmen have consistently excelled in its testing – by any standard. Whether it’s the arduous Norm Francais (NF 228), the equally demanding ASTM American standard or the current European Standard (BS EN 12326) there are test results to show its remarkable consistency over the years.
Del Carmen roofing slates are hewn from one of Spain’s most prestigious slate formations - an ancient and high-density rock celebrated for its uniform texture and exceptional durability. This geological pedigree is what enables Del Carmen slates to consistently surpass these stringent quality and performance tests making them a trusted choice for architects and heritage restorers across the globe. Remarkably, despite this superior origin and performance, we offer the standard selection at a price that remains firmly competitive. In fact, Del Carmen’s standard range routinely outperforms the so called ‘first class’ or ‘prime’ offerings from other quarries, redefining what true quality should look like. Elegant. Enduring. Unrivalled.
As always, as you are choosing a natural product it is recommended to allow a 10% surplus when ordering your slates. This accounts for cutting, breakages and natural irregularities. This precaution ensures full coverage, consistency in appearance and will help prevent delays during the fitting process.
