In roof constructions, using wood as a material for load-bearing structural elements in housing, public and other buildings is most common. A historical overview of the development of wooden roof structures is presented, so as the most important inventions that have enabled the manufacturing of a demanding wider range of structures (arch construction, stick construction, assembled constructions, and laminated carriers). The role of the roof structure has changed over time, and is becoming increasingly important for space utilization. The roof consists of a deck and a roof timber (to bear the burden, including the weight of the deck and its own weight). We systematically reviewed the various types of roof structures and described their components. The use of advanced fasteners is characteristic for modern wooden roof constructions. We have found that by selecting the correct timber joints mechanical resistance and stability of wooden roof structures can be significantly increased. We briefly described the traditional and modern wood carpentry joints. We examined and demonstrated a contemporary designed wooden roof structure - from planning to the final assembling. We visited the Kregar firm, where the usage of modern computer-controlled woodworking lines also produces sophisticated carpentry. Among other things, they made the highest standing wooden building in Slovenia - the lookout tower on Planina above Vrhnika.
