What Onduline does

Onduline is a privately-held French-founded international manufacturer of lightweight roofing and waterproofing systems, established in 1940 and headquartered in Paris. The company designs and produces bitumen-based corrugated roofing sheets (ONDULINE systems family including CLASSIC, EASYFIX, EASYLINE, EASYSTYLE), tile-look strips (ONDUVILLA), asphalt shingles (BARDOLINE), waterproofing membranes (BITULINE, BITUSMART), underroofing sheets (ISOLINE, ONDUTISS, Corotop), drainage membranes (FONDALINE), wood sandwich insulation panels (ONDUTHERM), polycarbonate daylighting (ONDUCLAIR), green roof systems (ONDUGREEN), and natural slate (ARDUVAZ). Its products use recycled content of 45-51% with measured carbon footprints, and are certified to ISO 9001/14001/50001 standards with FLL and Broof accreditations.

The company's business model is built on multi-channel distribution through country-specific websites, local teams, stockists (DIY stores, building supplies, timber merchants), online partners, and direct sales to professional contractors and project owners. It serves a hybrid customer base spanning residential DIY consumers, professional contractors and builders, agricultural facilities, commercial and industrial buildings, institutional/hospitality projects, and historical/heritage building restoration — supported by wholly-owned subsidiaries across France, the UK, Turkey, Ukraine, Spain, Vietnam, the Balkans, and beyond. Onduline manufactures in Sakarya (Turkey) and Pasuruan (Indonesia), the latter opened in November 2024, and maintains operations in more than 30 countries.

Revenue is generated primarily through hardware sales of roofing materials and integrated roof systems (SIATE family) sold via distributors and direct enterprise channels. Pricing is not publicly disclosed and is set by local dealers. The company has no public listing, no external PE/VC ownership evidenced in the data beyond a 2017 investment from Access Capital Partners, and is controlled through its French parent ONDULINE SAS with wholly-owned regional subsidiaries. The current CEO is Patrick Destang.

Direct peers

• IKO: Global manufacturer of bitumen-based roofing shingles, waterproofing membranes, and roof insulation systems. IKO competes head-to-head with Onduline across corrugated bitumen sheets, asphalt shingles (BARDOLINE equivalent), and flat-roof membranes in Europe, North America, and EM.
• BMI Group: European roofing group (formed from Braas Monier + Icopal) offering pitched and flat roofing systems including bitumen membranes and tiles. BMI directly overlaps with Onduline's ONDULINE, BITULINE, and ONDUVILLA product families across multiple European countries.
• Carlisle Construction Materials: US leader in single-ply EPDM/TPO membranes and roofing systems with growing international presence. Direct overlap with Onduline's BITULINE flat-roof waterproofing membrane line and compete for the same commercial/industrial roofing projects.
• Bauder Ltd: European manufacturer of bitumen-based flat-roof membranes, green roof systems, and insulation. Closely comparable to Onduline's BITULINE and ONDUGREEN product families and competes directly in UK, Germany, and other European markets.
• Tegola Canadese: Italian manufacturer of bitumen shingles and integrated roof systems with strong European presence. Directly competes with Onduline's BARDOLINE shingles and ONDUVILLA tile-look products across Mediterranean and Eastern European markets.
• Atlas Roofing Corporation: North American manufacturer of asphalt shingles, polyiso insulation, and underlayments. Product overlap with Onduline's shingle and rigid insulation panel ranges makes Atlas a relevant benchmark for system pricing and channel strategy.

Broad incumbents

• GAF Materials: North America's largest roofing manufacturer (Standard Industries) producing asphalt shingles, TPO membranes, and roof systems. While primarily US-focused, GAF's scale and system breadth in bitumen and polymer-modified roofing set a competitive benchmark against any global lightweight roofing player.
• CertainTeed (Saint-Gobain): Saint-Gobain's roofing division producing asphalt shingles, underlayments, and integrated roof systems. Competes with Onduline in residential asphalt shingles and overlaps in commercial membrane and insulation product lines.
• Owens Corning: Global building materials manufacturer with significant roofing (asphalt shingles) and insulation businesses. Comparable to Onduline in roofing distribution channels and overlaps with ONDUTHERM wood/insulation sandwich panels.
• Wienerberger: Austrian-based global leader in clay roof tiles and a growing roofing systems provider following acquisitions of Mejny, Creaton, and others. Competes with Onduline in pitched-roof coverings and increasingly in integrated roof solutions in Europe.
