Consolidated

What Consolidated does

Consolidated Nederland BV is a family-owned Dutch roofing specialist founded in 1962 and headquartered in Gorinchem, with 251–500 employees and regional offices across the Netherlands. The company manages, maintains, renovates, and upgrades flat and pitched roofs for professional property owners — primarily housing corporations (woningcorporaties), municipalities, healthcare institutions, and educational institutions. Core service lines include daily roof maintenance, planned (planmatig) maintenance, roof inspections against the NEN 2767 standard, renovation and sustainability upgrades (green/blue roofs, solar, circular materials), and a specialized sloped-roof brand (Consolidated Hellend). Production capacity reaches 10,000+ m² of roof surface per week through chain partners, with 20,000 leak reports processed annually and an 8.7/10 customer satisfaction score.

At the center of Consolidated's offering is Dakota, a proprietary roof-management platform used by 1,150+ clients to consolidate roof data, plan inspections, run multi-year maintenance budgets (MJOB), and coordinate all roof partners. The platform integrates with Inscio roof sensors (predictive moisture/temperature monitoring), the Dak App for field data entry, the new Lekkage App for resident self-reporting, and the Klant Informatie Module (KIM) for planned-maintenance communication. Dakota is also piloted with Vastware for ERP/budget integration and uses NL-SfB coding for standardized data exchange. The December 2025 platform renewal rebuilt Dakota on a modern, AI-ready technical foundation.

Consolidated monetizes through a result-oriented cooperation model with three tiers (Support, Advisory, Full-Service), combining day-to-day maintenance contracts, managed renovation projects, and Dakota platform licensing bundled into service agreements. Pricing is outcome-based with full cost transparency (unit prices, material costs, hourly rates disclosed to clients) and savings-share mechanics on multi-year contracts. Revenue is not publicly disclosed, and the company remains family-owned with no identified institutional investors or parent company.

Revenue model

1. Roof Maintenance Services: Day-to-day roof maintenance services including leak repairs, inspections, cleaning, and small repairs.

3. Dakota Platform Licensing: Dakota roof management software is made available to clients as part of the service package, providing data management, inspection tracking, maintenance planning and reporting. Revenue is bundled into service contracts rather than sold separately.
