Bihler

What Bihler does

Bihler GmbH is a family-owned master roofing company (Meisterbetrieb) headquartered in Pforzheim, Germany, founded in October 1983 by Oliver Bihler. The company provides a comprehensive suite of building envelope services centered on steep-slope (Steildach) and flat-roof (Flachdach) construction, supplemented by specialized trades including lightning protection (Blitzschutz), chimney construction (Kaminbau), sheet metal work (Baublechnerei), painting (Malerarbeiten), mastic asphalt (Gussasphalt), and crane/aerial lift rental. Differentiated service offerings include TÜV-certified bitumen and foil waterproofing, licensed drone-based roof and facade inspections, and a VELUX roof window configurator embedded on the company website. Operations are delivered through an in-house specialist workforce of approximately 45 employees using a proprietary fleet of cranes and lifting equipment, avoiding subcontractor coordination.

The business serves four primary customer segments in the Pforzheim region and surrounding ~50 km radius within Baden-Württemberg: private homeowners (primary segment), architects and planners, property managers and housing cooperatives (including Arlinger Baugenossenschaft), and municipalities. Revenue is generated primarily through project-based roofing and construction services with quote-based pricing, plus incremental crane/lift rental fees. The company markets through a combination of guild membership (Dachdeckerinnung), the IM LOT cross-referral network of architects, planners, and craftsmen, a corporate website with project references, and organic social media (Facebook and Instagram). The firm is a privately held GmbH with no external funding rounds, no parent company, and full ownership retained by founder Oliver Bihler, who serves as Geschäftsführer. Notable project credentials include the Villa Witzenmann heritage renovation (completed November 2017) and participation in the Hugo-Häring-Auszeichnung 2017-winning Picosens research building in Bühl.

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Wienerberger AG: Austria-headquartered, Europe's largest producer of clay roofing tiles and building solutions. Material category overlap with Bihler's Steildach (pitched roof) services and serves the same German construction market, though Wienerberger is a manufacturer/supplier rather than an installer.
• BMI Group (Braas, Icopal): European market leader in roofing and waterproofing systems including pitched-roof tiles and flat-roof membranes. Comparable as the dominant incumbent in the same product categories Bihler installs, though at vastly greater scale and across the full value chain from manufacturing to contractor networks.
• Creaton GmbH: German manufacturer of clay roofing tiles and roofing accessories (part of Wienerberger). Direct material category overlap with Bihler's pitched-roof installation work; serves the same Dachdecker channel through which Bihler sources roof tiles.

Regional players

• Holzbau Amann GmbH: Baden-Württemberg-based timber construction and carpentry firm. Comparable as a regional Handwerksbetrieb in the same broader building envelope and construction trades ecosystem, serving architect-driven projects in southern Germany.

Others

• Paul Bauder GmbH & Co. KG: German manufacturer of bitumen, foil, and PIR insulation roofing systems used in flat-roof and steep-roof applications. Direct material overlap with Bihler's TÜV-certified bitumen and foil installations; Bihler is a product training partner for Bauder's Liquitec and PIR systems.
• Sika Deutschland GmbH: Specialty chemicals company providing waterproofing membranes, sealants, and roofing systems used in flat-roof applications. Comparable as a supplier-side participant in the same flat-roof waterproofing market Bihler services with its TÜV-certified bitumen and foil work.
• VELUX Group: Global leader in roof windows and skylights, integrated into Bihler's website via the VELUX Dachfenster-Konfigurator. Comparable as a complementary product category sold and installed through roofing contractors, with a direct existing partnership providing Bihler quote leads.
• Rheinzink GmbH & Co. KG: German manufacturer of titanium-zinc and metal roofing/façade systems. Highly comparable on Bihler's Baublechnerei (sheet metal) and metal roofing service line, supplying the material category Bihler works with in its in-house workshop.
