What arlt & hanisch does

Arlt & Hanisch GmbH is a fourth-generation, family-owned German master roofing and building-envelope company headquartered in Sindelfingen, Baden-Württemberg. Founded in 1921 by master roofer Andreas Arlt in Warnsdorf and operating under the Arlt & Hanisch name since 1946, the firm is led today by Christian Hanisch and employs approximately 20 people, comprising roofers (steep and flat roof), carpenters, sheet-metal workers (Flaschner), apprentices, and general laborers. The company delivers a unified 14-service portfolio spanning flat-roof and pitched-roof renovation, carpentry, sheet-metalwork, facade cladding, industrial construction, green roofs, roof windows, terrace and balcony waterproofing, and — increasingly — photovoltaic systems, integrated solar roof tiles, and drone-based roof inspection with digital measurement.

The underlying technical stack is predominantly traditional craft combined with selective modern tooling: high-resolution drone photography, 3D photogrammetric modeling, and thermal imaging are used in the Dach-Check mit Aufmaß service to capture precise roof geometry and condition without scaffolding. All work is performed by in-house teams, with subcontracted specialists (metalwork, scaffolding, landscaping, fire protection) brought in via the Die Hand-in-Handwerker cooperative and a network of regional trade partners. The company is a member of the Dachdeckerinnung Stuttgart and holds the "100 Top Dachdecker" quality seal.

Revenue is generated entirely through project-based, quote-driven professional-services fees for residential, commercial, and industrial clients in the Stuttgart metropolitan area (Sindelfingen, Böblingen, Calw, Ludwigsburg, Esslingen, Enzkreis, Herrenberg, and surrounding districts). The go-to-market is direct-to-customer via website, phone, email, walk-in, and local-SEO city landing pages, supplemented by word-of-mouth referrals through the Stuttgart Roofing Guild and partner network. Pricing is not publicly disclosed; offers are valid for two weeks per the firm's AGB, with adjustments permitted for significant labor or material cost changes. Recurring revenue comes from preventive-maintenance contracts (Dachwartung) and drone inspection, while larger one-off revenue is driven by renovation, re-roofing, and increasingly solar-integration projects.

Core offering

Arlt & Hanisch is a German master roofing company (Dachdecker-Meisterbetrieb) based in Sindelfingen that sells and delivers roof construction, renovation, and maintenance services for pitched and flat roofs. The offering combines in-house roofing, carpentry, and sheet-metal work with complementary services including facade cladding, photovoltaic and solar tile installation, green roofs, roof windows, terraces, balconies, and industrial/commercial roofing. All services are project-based, executed by the company's own workforce of master craftsmen, and supported by drone-based roof inspection and digital measurement.

Product overview

Arlt & Hanisch is a traditional German master roofing company (Dachdecker-Meisterbetrieb) offering a unified portfolio of 14 distinct services. The core offering centers on roof renovation and construction for both pitched (Steildach) and flat (Flachdach) roofs, supported by in-house carpentry (Zimmererarbeiten) and sheet metal work (Flaschnerarbeiten). The company differentiates through solar technology offerings — photovoltaic panels (Photovoltaik), solar roof tiles (Solardachziegel), and roof greening (Dachbegrünung) — which integrate with its core roofing services. Add-on services include drone-based roof inspection with digital measurement (Dach-Check mit Aufmaß), preventive maintenance (Dachwartung), and professional consultation and planning (Beratung & Planung). Complementary offerings cover facades (Fassaden), industrial construction (Industriebau), terraces and balconies (Terrassen/Balkone), and roof windows (Dachfenster). The company operates as a single-service provider with all offerings delivered by in-house teams; there is no modular software platform.

Recent moves9 records

Expansion highlights6 records

Broad incumbents

• Paul Bauder GmbH & Co. KG: Germany's leading manufacturer of flat-roof and pitched-roof systems (membranes, insulation, green roof), supplying many of the materials Arlt & Hanisch installs. Comparable as a key German roofing ecosystem player, although Bauder is a materials maker rather than a service contractor.
• BMI Group (Braas / Icopal): Global roofing and waterproofing group; the German Braas brand is the dominant pitched-roof tile supplier while Icopal covers membranes. Comparable as the broader incumbent in the roofing value chain operating in Germany.
• Creaton GmbH: Major German manufacturer of concrete and clay roof tiles plus roofing system accessories. Comparable as a high-visibility incumbent in the same pitched-roof category Arlt & Hanisch specializes in.
• Wienerberger AG: Vienna-based building materials group with a strong German roof-tile portfolio (e.g., Koramic, Sandtoft). Comparable as a broader roofing-materials incumbent operating across Germany.
• VELUX Group: World leader in roof windows and skylights, deeply embedded in the German renovation market. Comparable because roof-window installation is one of Arlt & Hanisch's listed services and VELUX is the dominant upstream brand.
• Enke-Werk Johannes Enke GmbH & Co. KG: German manufacturer of roof coatings, liquid waterproofing and sealant systems. Comparable as a German specialist incumbent in flat-roof waterproofing, a core service line for Arlt & Hanisch.

Direct peers

• Holzbau Amann GmbH: Mid-sized Baden-Württemberg carpentry / timber-construction firm covering roof structures, roof renovation and energy-efficient building envelopes. Comparable as a similarly sized, multi-trade Southern German Handwerksbetrieb combining carpentry and roofing.

Regional players

• Holzbau Baden-Württemberg (regional Zimmerer / carpentry contractors): Network and members of the regional carpentry trade serving Baden-Württemberg with roof structures, timber framing, and renovation work. Comparable as overlapping regional carpentry and roofing-service peers rather than direct competitors in the same towns.

Others

• Zentralverband Deutsches Dachdeckerhandwerk (ZVDH): National German roofing trade association of which the regional Dachdeckerinnung Stuttgart, an Arlt & Hanisch partner, is a member. Comparable as the industry body shaping standards, training, and referral flows that directly impact small German roofing contractors.
• Holzbau Deutschland - Bund Deutscher Zimmermeister: Federal German carpentry association representing Zimmerer craft businesses. Comparable as the parent trade body for the carpentry (Zimmererarbeiten) service line Arlt & Hanisch operates.
