IDE Flachdachbau GmbH is a specialized German roofing and waterproofing contractor delivering flat roof construction, thermal insulation, green roof installations, and leak sealing across commercial, industrial, and residential sectors. As the lead WordPress developer, I designed and developed an authoritative, craft-centered digital presence engineered to highlight certified German trade craftsmanship (Meisterbetrieb), showcase industrial-scale projects, and generate qualified B2B and private renovation inquiries.
Project Snapshot
- Client: IDE Flachdachbau GmbH (Flat Roof Construction & Waterproofing Specialists)
- Role: Lead WordPress Developer
- Type: Trade Contractor & High-Intent B2B/B2C Lead Generation Website

The Objective & Challenges
- Communicating Technical Authority & Craft Standards: Flat roofing requires precision engineering and strict compliance with German building codes (DIN standards, thermal envelope regulations/EnEV). The site needed an authoritative, modern industrial look that immediately conveys reliability to commercial developers and private homeowners alike.
- Distinct Service Specializations: Flat roofing covers diverse specialized techniques—bituminous waterproofing, synthetic membrane sealing (PVC/FPO), green roof greening (Dachbegrünung), and thermal insulation. The service architecture needed to explain these distinct services clearly without technical overwhelm.
- Reference Projects & Social Proof: Building contractors and architects evaluate trades through photographic proof of completed work. The site required an intuitive, visual gallery engine to showcase completed residential terraces, logistics centers, and industrial roofs.
- Frictionless Project Inquiry Funnel: Transforming site visitors into qualified consultation requests by capturing key project parameters (roof size, new construction vs. refurbishment, urgency) at the initial inquiry stage.
