Dachdecker-Einkauf Sud eG

What Dachdecker-Einkauf Sud eG does

Dachdecker-Einkauf Sud eG (DE Süd) is a registered cooperative (eingetragene Genossenschaft, eG) headquartered in Mannheim, Germany, founded in 1970 and operating as a specialized wholesale distributor (Bedachungsfachhändler) for the roofing and construction trades. The company serves professional roofers (Dachdecker) and carpenters (Zimmerer) across Germany with a catalog of more than 25,001 SKUs spanning roofing systems, raw construction and facade materials, construction chemistry, fastening systems, outdoor/landscape products, tools and machinery, and workwear. DE Süd distributes products from over 100 manufacturer brands — including Velux, Roto, Lamilux, BMI Braas, Wienerberger, Rockwool, Erlus, Prefa, and Makita — alongside an own-brand private label line (DEG Eigenmarke) covering sealants, adhesives, insulation foam, waterproofing membranes, and bitumen primers.

DE Süd operates a hybrid distribution model combining 30+ physical branch locations across Germany with a login-gated B2B e-commerce platform that exposes only individualized, account-based pricing with applied discounts. The proprietary IDS-Schnittstelle interface connects customer tradesmen software (Handwerkersoftware) directly to the online shop for automated ordering and data synchronization, creating moderate software-based switching costs. Beyond core product distribution, DE Süd monetizes engagement through a Prämienshop reward points program, a Mietservice equipment rental service, Schulungen training/education programs, and a Handwerkersuche contractor referral tool. The company is a member of the ZEDACH eG cooperative purchasing group, which aggregates procurement leverage and shared services among affiliated German roofing wholesalers. The company also serves France in addition to its German home market.

DE Süd is privately held under member-cooperative governance, has 251-500 employees, and reports no external funding rounds, M&A, or leadership-change events in the available data set. Distribution partnerships with leading manufacturers constitute the primary commercial moat, supplemented by branch density, software integration, and private label depth.
