The roofs are the finishing touch that shape its overall appearance.
Beyond the overriding aesthetic messages, they provide a strong and stable finish without which any construction would be unthinkable. The type of roof depends on the configuration of the building, the climatic features, the architectural impact they aim to achieve, the presence of superstructures or parts of the building extending above the roof. The options for the shape of roof structures, the types of coverings and the method of water drainage are many and keep getting more complicated. If we restrict the scope of analysis in residential construction to the most common options, the choices are generally limited to two – pitched or flat. These groups are named according to their most typical feature – the slope of the roof planes.
Sloping roofs – these are characterised by a significant slope, which can vary within certain limits. According to the BDS in Bulgaria, pitched roofs are defined as those with a slope of more than 7%. The types of coverings for them are extremely varied – from the traditional and time-tested tiles, through smooth or profiled sheets, all the way to thatch and reeds.
FLAT COVERS – although it may not sound like it, they also have a slope. Although very small, it serves to channel water in a particular direction (towards the funnels). It varies from 1 to 7% (0.5 – 4°). Flat roofs must have a continuous (so-called ‘seamless’) covering or have absolutely watertight joints.
