TS 12814

TS 12814 is a occupational standard focused on the profession of wood roof construction, maintenance, and repair, defining the role and the core professional characteristics expected from the person performing it. Wood roofing work involves the assembly of load-bearing roof elements, the application of roof details and coverings, routine maintenance, and repair of damaged sections, so it depends on both craftsmanship and structural awareness.

Technical scope of the occupation

The standard covers the basic tools and equipment used in the profession, together with the measurement and evaluation of the qualities a practitioner should possess. In practical terms, this means the document addresses the professional framework around the job rather than only the work product itself. For wood roofing, accuracy in measurement, familiarity with materials, correct joining practices, and attention to safe working methods are central to reliable performance.

General technical context for wood roofing

From a general engineering and construction perspective, timber roofs rely on a structural system that transfers loads safely through rafters, purlins, supports, and related components. The work calls for understanding roof geometry, spans, fastening methods, moisture-related behaviour of wood, and the relationship between structural members and covering details. TS 12814 positions this occupation within a defined vocational framework and focuses on the competencies relevant to wood roof construction, maintenance, and repair.
