Do you need a new roof structure, canopy, or a wooden structure? Roof structures can be made of timber, metal, or concrete, but the most widely used material is timber. Wood is a natural material with the size, hardness, and weight in harmony, which reflects on the space where it’s used as it’s breathable and regulates humidity. A roof structure has to carry its own weight and the weight of snow and rain, too. The most used type of timber for building a roof structure is spruce, while larch and oak are not used that often. Freshly cut timber is a good option for open roofs, but timber has to be dried, with no more than 20% of moisture, in case of a closed roof. A wooden roof structure can be made by an experienced carpenter. The structure itself is made of roof beams, and includes eaves and ridges, while the secondary roof structure includes cross girders, purlins, and batten joints. Parts of the structure which will be exposed to the elements, are coated with protective lubricants. However, before you make any changes to an existing roof structure, have a designer or structural analysis engineer take a look and give their opinion. Generally speaking, we recommend you always do your research on applicable regulations in your local council or another authority to avoid any unpleasant surprises.
