Annotation: The paper is devoted to the problem of choice of technologies of repair of flat unventilated roofs of industrial building. The analysis of the organizational and technological documentation and literature has shown that in the reconstruction of industrial roofing repair work is done in the case of insufficient information on the state of the roof, excluding the features of the technology works and the impact of weather conditions and climatic factors. Methodology allowing is defining effective technical and economic decisions of repair taking into account the level of defects and damages of roofs is offered. The essence of the proposed technique is to select the technology of repair on the basis of models of technical and economic indicators. Multivariable models are estimating influence of level of defects and damages on the technical and economic parameters of studied repair roofs are presented. Coefficients of repair of roofing works with the evaluation criteria – the complexity and cost are identified. The critical level of defects, in which the choice of roofing repair method is determined by comparing the estimated cost, complexity and maintenance-free life of routine maintenance to overhaul the entire roof, is proposed. The index of the present value including a maintenance-free service life is shown. The method can be applied not only for repair non-ventilated flat roofs of industrial buildings, but also in the repair of roofs of civil and administrative purposes.
Keywords: technology of repair of roofs, the index of the present value of defects and damages, multivariable models of a cost and a labor, the coefficient of repair of roofing works, the critical level of defects, the index of the present value.
