Elro Duurzame Daken

What Elro Duurzame Daken does

Elro Duurzame Daken B.V. is a Dutch specialist contractor founded in 1987, headquartered in Apeldoorn, that designs, develops, builds, renovates and maintains sustainable flat and slightly sloped roofs. The company works with bitumen, EPDM, PVC and high-durability membranes (including Wédéflex materials with a proven 42-year lifespan) and offers a full roof lifecycle stack: green roofs, energy roofs (solar, including a lightweight panel system at 50% of conventional weight), circular roofs, retention roofs, parking roofs, and 24-hour emergency leak repair. Roof safety, fall protection and inspection services are delivered through the Elro Dakveiligheid and Zcure brands, including BRL 9935 certified fall protection systems.

Elro sells exclusively to professional B2B clients: housing corporations, municipalities, healthcare institutions, pension funds, institutional investors, and real estate managers. It does not serve individual consumers or new-build general contractors. Go-to-market is enterprise field sales built around Result-oriented Cooperation (RGS), a contractual model that replaces transactional performance obligations with multi-year 'result agreements' spanning 3-20 years, layered with NEN 2767-based inspections, multi-year maintenance forecasts (MJOP), and 24/7 emergency response. The company operates from five Dutch branches (Apeldoorn, Alkmaar, Gorinchem, Son and a Dakveiligheid office) and one German branch.

Elro is the flat-roof anchor of the Carefos group (formed 2021 with Batavorum Capital), which also includes Weijerseikhout, Volting, ZCure, Stekelenburg Glas, Duits Isolatie and (since 2024) Eurocover, Infinity Repair and Zaanstad Dakwerken. Group headcount exceeds 400 specialists, with Elro alone at ~200 employees as of January 2025. Revenue is generated through professional services (project-based renovation and installation), subscription/recurring revenue (multi-year maintenance contracts), and project + recurring inspection revenue in roof safety. Pricing is not publicly disclosed; cost structures suggest experienced roofers earn up to €4,000 gross/month and werkvoorbereiders €3,000-€5,000. The company holds ISO 9001, ISO 14001, VCA, KOMO, BRL 9935 and VGO-keur certifications, and was named best training company in the Dutch roofing industry (Gouden Brander 2025) by TECTUM.

Scale indicators5 records

Recent moves9 records

Expansion highlights6 records

Broad incumbents

• Koninklijke Heijmans N.V. Large Dutch construction and infrastructure company that operates broadly in building and renovation, including roofing and building envelope services. Comparable because it targets the same Dutch institutional and housing clients with overlapping capabilities, though as part of a much wider portfolio.
• Koninklijke BAM Groep N.V. Major Dutch construction group active across residential, commercial, and infrastructure. Comparable because it competes for the same Dutch housing corporation and institutional renovation budgets, including flat-roof and building envelope work, though its roofing activity is not the company's sole focus.
• Koninklijke VolkerWessels N.V. Large Dutch construction and real estate development group with extensive building envelope and renovation capabilities. Comparable because it serves the same Dutch institutional client base and competes for similar renovation, maintenance, and sustainability upgrade contracts.
• BMI Group (Braas Monier Icopal): International roofing and waterproofing manufacturer supplying membranes, shingles, and systems used by contractors including Elro. Comparable because BMI products compete with Wedéflex and other bitumen/EPDM/PVC systems Elro installs, and BMI is a major counterparty in the same flat-roof supply chain.
• Kingspan Group plc: Global building envelope specialist offering insulation, roofing membranes, and integrated wall/roof systems. Comparable because Kingspan competes in the same flat-roof and insulation market Elro addresses, especially as energy-efficiency and circular-economy requirements push integrated envelope solutions.
• Carlisle Companies Incorporated: US-based manufacturer of EPDM, TPO, and other commercial roofing membranes through Carlisle Construction Materials. Comparable because its membrane systems directly compete with and supply the Dutch flat-roof contractor market Elro serves.
• Soprema Group: International waterproofing and roofing specialist producing bitumen, synthetic, and liquid-applied membranes. Comparable because Soprema products are used in projects similar to Elro's, and the company operates in the same European flat-roof and building envelope market.
• TBI Holdings B.V. Dutch family-owned construction group with divisions in residential, non-residential, and infrastructure. Comparable because TBI competes for the same Dutch housing corporation and institutional renovation work, including building envelope and roofing scopes.
• Sika AG: Global specialty chemicals company producing roofing membranes, sealants, and waterproofing systems used by flat-roof contractors. Comparable because Sika's products are direct alternatives to those Elro specifies and install, including TPO and liquid-applied systems.

Others

• Vebidak: Dutch trade association for bituminous and plastic roofing companies of which Elro is a member. Comparable because Vebidak's members are the same peer contractor set Elro competes with, providing a useful industry consortium context rather than direct competitive overlap.
