Die Dachdecker-Einkauf Nordwest

What Die Dachdecker-Einkauf Nordwest does

DEX eG is a German purchasing cooperative (Einkaufsgenossenschaft) serving roofing contractors (Dachdecker), carpenters (Zimmerer), and specialized trade businesses (Fachbetriebe). Formed in August 2024 through the merger of DENW and DEG Dach-Fassade-Holz eG, the cooperative operates 33 branch locations across North Rhine-Westphalia, Lower Saxony, Bremen, Hessen, and Thüringen, with registered headquarters in Hamm and an administrative office in Weyhe. Members benefit from collective buying power, direct construction-site delivery, and exclusive services such as custom metal fabrication and facade panel cutting performed at the cooperative's own production facilities in Münster and Weyhe.

The cooperative distributes roofing and construction materials across 11 product categories — pitched roof (Steildach), flat roof and insulation (Flachdach & Dämmung), facade, wood (with timber processing services), metals and drainage (with in-house metal fabrication), photovoltaics, smoke and heat exhaust systems, lighting, fasteners and consumables, machinery and tools, and trapezoidal sheet / hall construction. Value-added services include the "12er Service" for scheduled small-materials delivery, the OBIS digital ordering and information platform, custom metal processing, facade cutting operations, maintenance and workshop services, and timber cutting (Abbundservice). The cooperative is part of the ZEDACH eG network, the central purchasing organization for the German roofing trade.

DEX eG generates revenue through product margins on sales to its member-customers, who are simultaneously the cooperative's owners. The go-to-market motion is primarily channel-based via the 33-branch physical network and the OBIS online portal, supplemented by trade fair participation (DACH+HOLZ International), the "Das Dach" member magazine, and social media outreach. Pricing is structured around membership agreements rather than public tiered pricing. Member businesses receive codified codetermination rights, profit participation, and access to exclusive events.
