the article considers the problem of determining the reliability and residual life of roofs of residential buildings, taking into account an integrated approach, which includes determining the reliability of each element taking into account physical wear and tear and calculating the reliability of the “roof” system using graph theory. Five two-story residential buildings in the Ryazan region were selected as objects for evaluation: in the city of Skopin and in the city of Ryazan. When examining the roof structure, typical damage was revealed: the absence (including fragmentary) of the roof covering, biological damage to the wood by the bark beetle, rot, warping of the boards and others. To assess these damages in determining physical deterioration (by external signs), departmental standards were used, the reliability of roof structures as a system of interconnected elements was determined on the basis of graph theory. It has been established that the roofs of two of the five buildings have reached an inoperative state, and the residual life for the roofs of three buildings ranges from 1 to 14 years.
