Rathscheck Schiefer und Dach-Systeme

What Rathscheck Schiefer und Dach-Systeme does

Rathscheck Schiefer und Dach-Systeme is a Mayen/Eifel, Germany-based manufacturer of premium natural slate products for roofing and facade applications, founded in 1793 and operating as a wholly-owned subsidiary of the diversified Werhahn Group (also owner of Zwilling). The company sources and processes natural slate from three wholly-owned Spanish subsidiaries — Grupo Cafersa S.L. (acquired 2008), Pizarras Castrelos S.A. (acquired 2013), and Pizarras La Baña S.A. (acquired 2023) — all operating in the Valdeorras/León region of northwestern Spain, which hosts Europe's premier slate deposits. Following the 2019 closure of unprofitable Moselschiefer mining at the historic Katzenberg site in Germany, Spanish production now anchors raw material supply.

The product portfolio spans over 25 specialized deck types (Altdeutsche Deckung, Rechteck-Doppeldeckung, Horizontale Deckung, Dynamische Deckung, etc.) sold under established brands including InterSIN (blue-grey slate), MONUMENTUM (premium traditional German covering), ColorSIN (red and green tones), ROCANEX (natural stones), and Moselschiefer (garden and landscaping). The patented Rathscheck Schiefer-System enables faster rectangular slate installation and flush-integrated photovoltaic mounting, forming the basis for the Rathscheck Solar line (Indach-PV at 4 cm or 9 cm installation heights, plus the 2025-launched Aufdach-PV rooftop system). Specialized proprietary tools (BlattSklent, FixSklent, ThermoSklent, DrillSklent) and the 2026-launched UltraRechteck-Deckung — a single-layer rectangular covering at approximately 22 kg/m² requiring only 11 stones per square meter — round out the install-side offering.

Rathscheck operates a hybrid go-to-market combining (i) specialist building material merchants (Fachhändler) as primary resellers, (ii) a network of certified slate roofers (Schieferdecker) supported through the Lehrverleger on-site training service, (iii) direct consultation for building owners via the Bauherrenberatung service, and (iv) an Architect Portal with BIM data, specification templates, and continuing-education webinars. Pricing is project-based at approximately EUR 22–85 per square meter for standard slate coverings up to EUR 80–150+ per square meter for premium MONUMENTUM and ColorSIN products, with photovoltaic systems priced as integrated hardware packages. The company employs 251–500 staff and distributes across at least 10 European countries (Germany, France, UK, Belgium, Austria, Switzerland, Denmark, Netherlands, Luxembourg, Poland).
