Joly S.A.S.

What Joly S.A.S. does

Joly S.A.S. is a privately-held French family construction company founded in 1926 and headquartered in Saint-Marcel (Eure), specializing in building envelope works for public and industrial clients. The company is led by Pierre Edouard Quettier, who assumed ownership in 2011 from his father François Quettier, continuing multi-generational family control under a SAS (Société par Actions Simplifiée) structure with €390,000 share capital. Operations are organized around four service lines: Couverture (roofing in slate, terracotta, zinc, copper, stainless steel, and titanium), Bardage (facade cladding in steel, zinc, copper, polycarbonate, wood, and Trespa terracotta), Étanchéité (waterproofing of flat roof terraces via bitumen, gravel-surfaced, PVC, and accessible systems), and Développement durable (green roofs and integrated photovoltaic panels). Adjacent offerings include maintenance, handling/crane services, and equipment rental through the JOLY RENT subsidiary.

The group's technical backbone is an in-house transformation workshop equipped with CNC machinery (4ml electric shear, 4ml hydraulic press brake, CNC standing seam profiler, large-format panel saw) and an integrated design office producing execution plans and dimensional calculations. A wholly-owned subsidiary structure (Joly Etanchéité for sealing, Joly Services for maintenance, Joly Rent for equipment rental) enables a one-stop-shop delivery model. The firm employs roughly 50–70 people across the group, is ranked among the top 100 roofing companies in France by XERFI-Plimsoll among more than 10,000 sector firms, and serves clients across Normandy and Île-de-France.

Revenue is generated through project-based B2B contracts for new construction, renovation, and maintenance, with pricing set per project scope and materials rather than via published rates. Customers are predominantly public institutions (colleges, schools, hospitals, mairies) and industrial/commercial owners (garages, retail, hospitality, manufacturing, heritage buildings), with no single anchor account dominating the disclosed portfolio. The 2022 receipt of a France Relance grant for workshop modernization evidences recent capital investment to sustain custom-fabrication capability, while the addition of sustainable solutions (green roofs, solar integration) signals alignment with public-sector energy-efficiency mandates.

Direct peers

• Soprema: Soprema is a leading French manufacturer and contractor of waterproofing, roofing, and insulation systems. Directly comparable as a vertically integrated building envelope specialist; serves the same public/institutional and industrial customers as Joly across France.
• SMAC (Smac Group): SMAC is one of France's largest specialty contractors focused on roofing, waterproofing, and building envelope works. Directly comparable to Joly in core service offering (couverture, étanchéité, bardage) and customer segments, but operates nationally at significantly larger scale.
• Etandex: Etandex is a French specialist in waterproofing, roofing, and structural sealing for buildings and infrastructure. Directly comparable on étanchéité and couverture services for public and industrial clients; regional footprint overlaps with Joly's Normandy/Île-de-France base.
• Technitoit: Technitoit is a major French roofing, façade, and home renovation franchise with national coverage. Comparable on roofing and ITE service offerings; competes with Joly for the residential and small commercial renovation segment across France.

Broad incumbents

• SPIE France: SPIE is a major French multi-technical building services provider covering electrical, mechanical, and façade/roofing maintenance. Comparable on building envelope maintenance services for public and industrial clients but operates as a broad incumbent with multi-trade scope beyond Joly's roofing focus.
• VINCI Construction France: VINCI Construction is one of France's largest building contractors with capabilities spanning roofing, waterproofing, and envelope works. Comparable on large public/institutional tenders but operates nationally and internationally at a fundamentally different scale than Joly's regional specialty focus.
• Eiffage Construction: Eiffage is one of France's largest construction groups with significant roofing, cladding, and envelope capabilities through its subsidiaries. Comparable on public/institutional building envelope projects but operates as a broad incumbent with multi-region and multi-trade coverage that dwarfs Joly's scale.
• Sika France: Sika is a global specialty chemicals company with a strong waterproofing and roofing systems portfolio in France. Comparable on waterproofing membranes (PVC, bitumen) and sustainable roofing solutions; competes indirectly via material supply and contractor networks.
• Saint-Gobain France: Saint-Gobain is a global building materials leader with a broad façade, roofing, and insulation portfolio. Comparable through its ITE and cladding product lines serving the same public/industrial renovation market, but as a broad incumbent rather than a specialized regional contractor.

Emerging players

• RenoStyle / Renovimo (regional renovation networks): RenoStyle and similar French regional renovation networks focus on residential roofing, ITE, and energy retrofit. Comparable on residential and small commercial envelope renovation work; competes with Joly's residential segment in Normandy and Île-de-France.
