The paper presents results of studies conducted in an agricultural village about the types of roofing materials appearing on buildings. Particular attention was given to buildings covered with asbestos. Based on surveys, an inventory of roof surfaces, assessing their technical condition and calculations have shown that in the village up 30.3% of the buildings have coverage of asbestos-cement boards. On 33.8% boards were found occurrence of fungi and moss and cracks that contribute to the release of asbestos fibers into the environment. Own measurements of boards weight were shown that during 17 years of use, the loss of boards weight in the village area in total amounted 3853.82 kg. Were noted a high awareness of the rural population about the dangers of asbestos on human health and the environment whilst absence of financial resources associated with the need to disposal of asbestos as a hazardous material.

The paper presents analysis of existing concrete tiles roofing on outbuildings in selected localities of the Pińczów district. On the basis of the observations on the spot it was established that concrete tiles constitute 18% of all roof coverings in the investigated area. It is the most frequently used on livestock housing. It was noticed that of all concrete tiles, 81% are the products manufactured using traditional methods, directly on the construction site. Water absorption by weight was determined for selected concrete tiles in order to assess the technical state of existing concrete tiles roofing. The tests of water absorption by weight revealed about 1.6% lower water absorption for tiles mass produced by industry than for traditionally manufactured ones. The tiles utilised on buildings for more than 40 years were characterised by even 0.7% increase in water absorption by weight in comparison with non-utilised tiles. ...
