The roof structure supports the roofing tiles and forms part of the building's structure. The wooden roof structure is the most frequently employed. It is constructed in several ways; frequently as a triangular wood construction (rafter and collar tie). The crucial role is played by well-made wooden connections between structural elements. The quality planning and execution of wooden roof frames with wooden connections that are characteristic of the local environment are of the utmost importance. New wooden roof frame designs are also possible (glued laminated beams, trusses).
The doctrine of renovating stone buildings using reinforced concrete angled slabs with reinforced concrete bond beams was quite frequent decades ago. A reinforced concrete shell is earthquake resistant, but is unsuitable during an earthquake when combined with stone walls. Examples of the roof structure slipping off the building are frequent. The building is damaged severely by such slippage. When renovating, reconstructing or building new buildings with a stone roof, it is better to employ wooden roof support structures. A wooden roof frame is more dynamic during an earthquake and does not exacerbate the swaying of the building during earthquake accelerations. It should be mentioned that changes to the construction of the building are only possible on the basis of a comprehensive project design and the acquisition of a building permit.
