Dakdekkersbedrijf Admiraal BV

What Dakdekkersbedrijf Admiraal BV does

Dakdekkersbedrijf Admiraal BV is a Netherlands-based, family-owned roofing and facade contractor founded in 1978 by brothers Gerard and Piet Admiraal and currently led by second-generation owner Rory Admiraal. The company specializes in flat and sloped roof waterproofing systems (bituminous membranes, EPDM, PVC/TPO, shingles, corrugated sheets) and steel and aluminum facade systems (sandwich panels, trapezoidal/sinusoidal profiles). Its technical capabilities span torch-applied and cold-adhesive membrane installation, mechanical fastening, integrated green/solar/air-purifying roof assemblies, fall protection system installation, and BIM-coordinated design using Autodesk Revit LT, with execution carried out by in-house crews.

The company sells exclusively to commercial and institutional clients — property developers, housing corporations, healthcare institutions, cultural venues, retail chains, and industrial owners — across North Holland, South Holland, Utrecht, and Flevoland, with maintenance-contract roof inspections extending nationwide. Pricing is quote-based with a 10-year warranty on completed work; revenue is project-based and episodic, supplemented by recurring maintenance contracts. Customer acquisition is entirely direct, driven by telephone inquiries, general contractor relationships (BAM, Dura Vermeer-De Nijs, Vorm Bouw), and reference projects such as EYE Filmmuseum, Hotel Arena Amsterdam, Theater De Stoep, Theater De Kampanje, and C&A Amsterdam.

The business is privately held under BV structure (restructured from VOF in 2012), with no institutional investors, no subsidiaries, and no M&A activity. Operating certifications include VCA* (occupational safety) and ISO 9001 (quality management), both obtained in 1997. The firm maintains a workforce of approximately 7 employees and participates in vocational training via TECTUM, having been recognized as best training company (Gouden Brander) in 2018.

Scale indicators3 records

Recent moves11 records

Expansion highlights5 records

Broad incumbents

• IKO: International waterproofing and roofing systems manufacturer (bitumen, EPDM, PIR insulation). Comparable as a competing systems supplier active in the Dutch and broader European roofing market, with vertically integrated contracting capability in some regions.
• BMI Group: International roofing and waterproofing group (formerly Braas Monier / Icopal). Comparable because Admiraal uses BMI-owned Icopal membranes as a primary system across its projects, and because BMI operates integrated roofing contracting and systems businesses across Europe that compete for the same institutional envelope work.
• Carlisle Construction Materials: Major North American/EU manufacturer of EPDM (Resitrix) and bituminous membrane systems. Comparable because Carlisle is Admiraal's premium EPDM supplier (Hotel Arena, other projects) and competes in the same waterproofing systems category across European institutional and commercial projects.
• Kingspan Group: Global building envelope manufacturer of insulated sandwich panels (KS900), PIR insulation, and integrated roofing/wall systems. Comparable as a supplier of the same sandwich panel and insulation systems Admiraal installs and as a broader incumbent capturing value across the roofing and facade value chain.
• Derbigum: Belgian-rooted bituminous membrane manufacturer and waterproofing systems provider with strong Benelux presence. Comparable because Admiraal uses Derbigum membranes on projects and Derbigum operates its own contracting and systems business in the same Dutch/Belgian market.
• Soprema: Global waterproofing manufacturer of bituminous, synthetic, and liquid-applied membranes. Comparable as a systems supplier and competitor for the same commercial/institutional waterproofing projects that Admiraal bids on, with greater geographic reach across Europe.

Direct peers

• Oranjedak: Largest Dutch roofing contractor, operating nationally across flat and sloped roofing, facade, maintenance, and safety systems. Directly comparable as a Dutch commercial/institutional roofing contractor with a similar service mix (bitumen, EPDM, fall protection, maintenance contracts), but operating at materially larger scale.
