What Pelti-Ässät Oy does
Pelti-Ässät Oy is a Finnish roofing contractor founded in 2002 and headquartered in Vantaa, specialising in flat and low-slope roofing across bitumen, sheet metal, tile, and PVC systems. The company operates under two principal service brands: Kattokorjaamo (Roof Repair Workshop), the customer-facing maintenance and repair operation launched in 2025, and Kate-Ässät, the core contracting unit handling bitumen and sheet metal roof installation and renovation. Service portfolio spans the full roof lifecycle: new installation, renovation, preventive maintenance (SUJUVA annual contracts, JATKOTURVA+ extended warranty up to 20 years), expert condition assessments using TTS-PRO certified inspectors and Electric Leak Detection (ELD), polyurea coating, snow and ice removal, fire barrier inspection, and ancillary services including solar PV and green roof installation.
The company generates revenue through a mix of one-time project contracts (new installation and renovation, approximately €5 million annual revenue disclosed) and recurring maintenance subscriptions, plus professional-services revenue from inspections and long-term planning (PTS). Direct enterprise sales drive acquisition, with named account managers bidding on competitive tenders and securing framework agreements. Primary customer segments are Finnish housing cooperatives (taloyhtiöt) and construction firms and property developers; secondary segments include commercial and industrial property owners and professional property managers. Named enterprise clients include Kojamo, Hoas, Lumo-Kodit, Retta Management, Lidl, Skanska, Peab, Varte, and Toivo Group, with the company having served 2,700 customers and completed 9,700+ maintenance assignments across 3 million m² of roof area over its history.
Operations are concentrated in Uusimaa with selective coverage in Varsinais-Suomi and Keski-Suomi. The company holds RALA qualification, Ekokompassi environmental certification (grade A), Green Building Council Finland membership, and sources fossil-free electricity; carbon footprint has been reduced 41% over approximately three years toward a 2030 carbon-neutrality target. Leadership comprises CEO Jorma Laakkonen (with responsibility for bitumen roofing operations), Business Directors Mika Karsikas (bitumen roofing) and Miika Nygård (roof maintenance), and Sales Manager Pekka Järvelin, supported by approximately 34 employees. The company is privately held with no disclosed institutional investors or parent entity.
