The results of field surveys of the condition of building facades are presented. It has been established that cracking and peeling are among the priority defects of decorative plaster surfaces of building facades. The value of stresses of paint coverings from the action of temperature is estimated depending on the roughness of the cement substrate. To assess the stress state of the coverings, the SCAD Office software module was used. The calculation model is a shell finite elements with a size of 0.1 × 0.1 mm. Roughness modeling in the substrate was performed by changing the mesh type at the substrate-paint contact points. The effect of surface roughness on the value of stresses and the probability of cracking of coatings has been studied. An uneven allocation of stresses in the zone of contact between the coating and the surface was revealed. In the cold season, compressive stresses arise in the coverings. In the zone of contact with the surface, a concentration of compressive stresses is observed, and tensile stresses also arise in places where the relief of the surface changes. Under the action of tensile stresses in the period from March to September, tensile stresses arise in the coverings. The probability of coverings cracking is estimated.
