Detailed Information on Publication Record

The aim of paper is to provide information on the defects of roofing and roof structure on Apartment house Kaplice. Roof cover is Beronit fiber-cement template cover. The roof template is 400 x 400 mm (square with corrugated corners). The roof was laid according to design documentation and documented invoices 10 years ago. The roof as a whole, as a result of very serious defects, does not fulfill its function (protection of the object from weathering). The rainwater penetrates into the attic and affects the wooden elements of the roof structure. Wooden elements of truss construction, in particular formwork and rafters in the ridge area, are infested with mold. The Czech Mycological Society confirmed the attack of wood mold elements, testing the samples taken. One sample from the inside face of the roof formwork has higher mold values, and the other sample has even high mold values. The attic space can only be ventilated through the opening windows and the roofing is designed as unpaved. During the ten-year lifetime of the roofing, one repair was carried out, which further aggravated the condition. The detected state of the roof is emergency and the implemented measure in the form of capturing penetrated water into plastic containers is not enough to stop the deepening of destructive roof processes. Temporary repairs to roof roofing did not benefit, and on the contrary, it is one of the main factors causing cracking and shading of roofing patterns and thus the penetration of rainwater into the soil.
