What Hagmans Tak does
Hagmans Tak is a privately held Swedish roofing and waterproofing contractor founded in 1960, operating through seven regional limited companies (Hagmans Tak Norr AB, Mitt AB, Stockholm AB, Mälardalen AB, Öst AB, Göteborg, and Syd AB) that together employ approximately 100 people across Sweden. The group's core offering is complete waterproofing of flat and low-slope roofs, terraces, courtyards, and green roofs, executed under an exclusive partnership with Mataki for Swedish-climate-optimized tätskikt systems (products such as UnoTech FR and AluShell vapor barriers), with all work backed by the TÄTSKIKTSGARANTIER warranty program covering materials, workmanship, and consequential damages. Adjacent service lines include green roof installations (via VegTech), sheet metal painting, roof safety installations, and recurring service and maintenance agreements; a more recent solar PV integration partnership with Nordic Solar Sweden AB and HSB Värmland extends the offering into energy-efficiency retrofits for housing cooperatives.
The business model is predominantly project-based professional services revenue, supplemented by recurring service and maintenance contracts and energy-efficiency retrofit work. Pricing is custom-quoted per project with multi-year contracts; the go-to-market is enterprise field sales delivered through the seven regional offices, secured via competitive bidding, ramavtal framework agreements, and direct relationships with construction companies, general contractors (e.g., Fastighetsbyggen i Väst AB, NCC), property managers, housing cooperatives (BRFs such as Masthugget and Blixten), municipalities (Strängnäs Kommun), healthcare facilities (Mälarsjukhuset), and industrial clients. The company's competitive positioning rests on six decades of brand reputation, nationwide regional coverage, certified installer talent (authorized through Sveriges Takentreprenörer and Mataki Partner), and ISO 9001/14001/45001 certifications held across the Mitt and Stockholm entities. No revenue, headcount growth, or ownership data are disclosed; the firmographic band of 251–500 employees is inconsistent with the stated ~100 employees across regional offices.
