Jacobi Walther Roof Tiles

What Jacobi Walther Roof Tiles does

Jacobi Walther Roof Tiles is a privately held German manufacturer of clay roof tiles (Tondachziegel) operating through three legal entities — Jacobi Tonwerke GmbH, Dachziegelwerke Bilshausen GmbH & Co. KG, and WALTHER DACHZIEGEL GmbH — with roots dating to 1859 and approximately 400 employees across two manufacturing sites in Bilshausen and Langenzenn. The company is family-led, with managing directors Helmut Jacobi, Max Nikolaus Jacobi, Lucas Jacobi, Günther Reese, and Dominic Wilhelm Jung holding leadership across the group, and positions itself as one of the strongest and most experienced medium-sized firms in the German clay roof tile industry, with over 165 years of continuous operating history.

The core product portfolio spans twelve or more clay tile formats — including Flachdachziegel (J11v, J13v, W4v), Flachziegel (Stylist), Hohlfalzziegel (Z5), Romanische Pfanne (Marko), Doppelmuldenfalzziegel (Z2, Tradition), Hohlpfanne (H1, H2), Krempziegel (K1), and Biberschwanzziegel — each available in multiple surface treatments and color series. In 2024 the company extended into building-integrated photovoltaics with two complementary offerings: the Stylist-PV solar roof tile, developed in partnership with autarq GmbH to embed solar cell technology into the Stylist flat tile, and the J160-PV indach (in-roof) solar module. Multiple tile models carry certified hail resistance at classes 4 and 5 from the IBS-Institut, and the company maintains a Biber Manufaktur workshop for custom heritage tile production.

Revenue is generated through hardware sales of tiles, accessories (ceramic and non-ceramic — ridge tiles, verge tiles, storm clips, snow guards, mounting systems), and solar tile packages, distributed exclusively through a network of specialist building materials dealers (Fachhändler) and roofing trade partners across Germany, with additional export presence indicated by country-specific websites for Denmark, the Netherlands, Romania, Poland, and Italy. Pricing is dealer-quoted and project-specific with no public price list. The company supports dealers and contractors with a suite of digital planning tools — a mobile technical app, snow load and wind suction calculators, drone-based roof measurement, and free sample tile ordering — and serves customer segments including homeowners, roofing contractors, architects, specialist dealers, and heritage building conservation projects.

Revenue model

1. Clay roof tiles (Tondachziegel): Core revenue from manufacturing and selling clay roof tiles in a wide variety of forms (e.g., Flachdachziegel, Hohlfalzziegel, Doppelmuldenfalzziegel, Biberschwanzziegel, Krempziegel, Romanische Pfanne, Reformziegel, Trendziegel) and surface finishes/colors. Tiles are sold through a network of specialist dealers and directly to roofing contractors. Revenue is one-time per project, though repeat orders from ongoing construction activity drive recurring demand.
2. Building-integrated photovoltaic / Solar roof tiles: Stylist-PV and J160-PV solar roof tile solutions that integrate solar modules into the roof surface. These higher-value products combine clay tiles with PV technology and are sold alongside standard tiles or as replacements. Revenue is generated from tile-plus-solar package sales, typically project-based.
3. Accessories (Zubehör): Ceramic and non-ceramic accessories including ridge tiles (First), hip tiles, verge tiles (Ortgang), valley tiles (Kehlziegel), snow guards, storm clamps, sanitary vents, and solar mounting systems. Accessories are sold as complements to roof tile purchases and generate additional per-project revenue.

Partnerships

Three partnerships are on record, tiered core and minor.

• autarq GmbHcoreTechnology or Integrationautarq GmbH (Brüssower Allee 87, 17291 Prenzlau) provides the solar cell technology integrated into Jacobi's Stylist-PV solar roof tiles. The partnership enables Jacobi to offer building-integrated photovoltaic solutions where the solar module is seamlessly combined with the Stylist clay tile. Customer inquiries for Stylist-PV are forwarded to autarq for processing and installation. autarq handles the PV-specific technology while Jacobi provides the structural clay tile base.
• ADOBE Architekten + Ingenieure GmbHminorImplementation/ SI/ Consulting PartnerADOBE Architekten + Ingenieure GmbH from Erfurt planned the renovation of a historic listed building in Nebra with Stylist-PV solar roof tiles, including an emergency-power-capable inverter, battery storage system, and electromobility charging system.
• Dachdeckerfachbetrieb Fehse GmbHminorImplementation/ SI/ Consulting PartnerDachdeckerfachbetrieb Fehse GmbH (Lützower Str. 17, 06642 Memleben) installed over 1,000 Stylist-PV solar roof tiles on the historic listed building in Nebra.

Others

• Autarq GmbH: German BIPV technology provider that supplies the solar cell technology for Jacobi's Stylist-PV roof tiles. Listed as a partner rather than a competitor, but represents adjacent/comparable capability in building-integrated photovoltaics.

Direct peers

• Laumans GmbH: A traditional German clay roof tile manufacturer with a heritage positioning and product range overlapping Jacobi's portfolio (interlocking tiles, plain tiles, heritage formats). Competes for the same heritage/denkmalgeschützte renovation segment.
• Creaton (Terreal Group): A leading German manufacturer of clay roof tiles, part of the European Terreal Group. Competes head-to-head with Jacobi in clay tile formats, colors, and heritage/denkmalgeschützte restoration segments, with overlapping dealer distribution in Germany.
• Erlus AG: A German clay roof tile manufacturer based in Bavaria, with a comparable premium positioning, broad tile portfolio (including flat and interlocking tiles), and similar dealer-driven distribution model focused on the German market.
• Nelskamp Dachziegel: A German roof tile manufacturer producing both clay and concrete tiles, with overlapping product categories, dealer network distribution, and a similar mid-market residential focus. Provides direct competition across multiple tile formats.
• Braas (BMI Group): One of the largest German clay and concrete roof tile manufacturers, directly competing with Jacobi across flat tiles, interlocking tiles, and complete roofing systems. Operates as a division of the international BMI Group, offering comparable product breadth and dealer distribution.
• Röben Tonbaustoffe: A German manufacturer of clay building products including roof tiles. Competes with Jacobi in the clay roof tile market with a comparable heritage positioning, color and surface variety, and dealer-based distribution.

Emerging players

• Tesla (Solar Roof): A large-scale entrant in building-integrated photovoltaics targeting aesthetic solar roofing at residential scale. While currently US-focused, Tesla's entry into European aesthetic-PV would compete directly with Jacobi's BIPV value proposition.
• Meyer-Haake Dachbaustoffe: A smaller German roof tile manufacturer offering clay and concrete tiles. Overlaps with Jacobi on clay tile formats but operates at a smaller scale, typically competing in regional German markets rather than nationally.

Broad incumbents

• Wienerberger AG: The world's largest producer of clay bricks and a major European roof tile manufacturer (including clay and ceramic roofing). Competes with Jacobi in clay roof tiles while also serving broader masonry and building envelope markets with much greater scale and geographic reach.
