Analysis of technologies for installing roofs on flat coatings using the floating method

Abstract

The article analyzes the current state of technologies for the installation, improvement, and restoration of flat roofs using the partial-melt method for bitumen–polymer roll materials, which remains one of the most widely applied techniques in construction practice. A range of technological factors affecting the quality of the completed roofing system is identified, including temperature regime, condition and preparation of the substrate, type and properties of roofing materials, burner movement speed and spatial position, weather conditions, and worker qualification. The study examines key process deviations that lead to defects, damage, or premature deterioration of the roofing structure. Current regulatory requirements governing structural solutions and working conditions are reviewed.

A literature analysis is presented, covering research by Ukrainian and international scholars, including V. Zhvan, S. Sovach, as well as recent experimental developments by E. Díez Jiménez, M. Fernández Muñoz, A. Barragán García, and others. Technological solutions are classified according to the level of mechanization, types of materials used, and organization of the technological process. Special attention is given to various heating methods – gas burners, infrared radiation, and their inherent limitations.

The study identifies major shortcomings of existing approaches, such as high labor intensity, low mechanization, fire hazards, and risks of compromised waterproofing. Although available studies contribute to improving the method, they remain incomplete, fragmented, and do not form a comprehensive system of technological guidelines. The research highlights the need for further investigation of the relationships between heating temperature, depth of bitumen softening, uniformity of heat distribution, and adhesion to the substrate.

The paper substantiates promising directions for enhancing the partial-melt roofing technology with regard to improving installation quality, operational durability, safety, and overall efficiency.
