Organizational and technological solutions for installing polymer membrane roofs in subzero temperature conditions

Abstract

In conditions of sharp cold spells, typical for Arctic and similar regions, the installation of roofing requires the use of special materials and technologies capable of maintaining their operational properties at sub-zero temperatures. This paper examines organizational and technological solutions related to the use of polymer membrane roofing systems, including PVC (polyvinyl chloride), TPO (thermoplastic polyolefin), and EPDM (ethylene propylene diene monomer) membranes. A comprehensive analysis is provided of the physical and mechanical properties of these materials, with emphasis on their frost resistance, elasticity, long-term watertightness, and durability under mechanical stress. Special attention is paid to the practical aspects of installation during the winter season, including weld temperature ranges, base surface preparation, storage and transportation conditions, and measures for ensuring installation quality under strong winds, precipitation, and limited daylight hours. The article identifies key challenges encountered during cold-climate roofing operations, such as reduced seam strength due to temperature deviations, increased defect rates from poorly prepared substrates, logistical complexities, and labor shortages. Technological procedures and process maps are presented that help mitigate these risks, including preheating methods, use of protective coverings, precise control of welding equipment settings, and targeted worker training. The article emphasizes the importance of an integrated approach to project design, logistics, and work organization to ensure the high reliability and long-term performance of polymer roofing membranes in freezing climates. The study concludes with a rationale for optimal solutions that align material properties with construction process requirements.
