DEX eG

What DEX eG does

DEX eG is a registered cooperative (eingetragene Genossenschaft) and the leading purchasing cooperative for roofing and construction materials (Dachbaustoffe) in Germany, formed in August 2024 through the merger of DENW (Deutsche Dachbaustoffe Genossenschaft) and DEG Dach-Fassade-Holz eG. The cooperative is member-owned and serves professional tradespeople — primarily roofers (Dachdecker), carpenters (Zimmerer), and metalworking trades (Klempnerhandwerk) — across 33 branch locations in five German federal states: North Rhine-Westphalia, Lower Saxony, Bremen, Hesse, and Thuringia. Governance is exercised through a supervisory board (Aufsichtsrat) and management board (Vorstand), with the Generalversammlung as the highest decision-making body. DEX eG is a member of ZEDACH eG, the central purchasing cooperative of the German roofing trade.

The cooperative's product portfolio is organized into 11 product worlds (Produktwelten) covering Belichtung (roof windows/daylighting), Befestigungsmittel & Verbrauchsmaterial (fasteners/consumables), Fassade (facade systems), Flachdach & Dämmung (flat roof/insulation), Holz (wood/timber), Maschinen & Werkzeuge (machines/tools), Metalle & Entwässerung (metals/drainage), Photovoltaik (solar), Rauch-Wärme-Abzug (smoke/heat vents), Steildach (pitched roof), and Trapezblech & Hallenbau (trapezoidal sheet/hall construction). Operational differentiators include in-house metal processing (bending, profiling, and special fabrication), large-format facade panel cutting at facilities in Münster and Weyhe, wood cutting and Abbund services, and the 12er Service — a scheduled auto-replenishment program for fasteners and consumables delivered directly to member business premises. The OBIS online ordering and information portal serves as the digital procurement channel.

DEX eG generates revenue through wholesale sale of building materials to members and customers, supplemented by project-based service fees from metal processing, cutting, Aufmaßservice, and logistics/site delivery. Distribution is exclusively domestic, executed through direct sales at branches, the OBIS self-serve portal, and site delivery to construction projects. Public pricing is not disclosed; pricing is member-restricted, and the company is not publicly traded.
