| Summary: | There are several possibilities how to deal with a roof drainage. From an architectonic point of view an improper and unsuitable system is chosen in a majority of cases which may be as a logical consequence the beginning of upcoming problems. One of these problems is typically connected with either a roof location near the parapet wall, or in the corner of a flat roof. Another one is generally represented by a roof drainage solution with a side inflow for the drainage system that goes through the parapet wall construction. This solution is represented by a useful space
increase in a layout of the building and an installation of a rainwater drainage core is not necessary in such cases. In case more of negative effects accumulate, such as an improper thermal insulation quality or insufficient thickness of the thermal insulation, significant problems may appear hand in hand with using of the building. These problems are generally represented by a moisture appearance in the inflow area. What more, this is not always detected and a major cause can be determined very hardly. This article deals with possible solutions for the wooden construction failure caused by the moisture that may emerge as an improper inflow layout consequence.
