Sustainable Industrial Roof Renovation in the Rhineland with HERTALAN® EASY COVER and Induction Technology.
Repeated leaks in an industrial roof in the Rhineland, allowing water to penetrate the building and electrical systems, led to operational restrictions and failures in the warehouse systems. As a result, the property owner commissioned an expert to inspect the affected roof areas and develop a renovation plan. Shortly thereafter, a hailstorm severely damaged the flat roof of one of the warehouses, which had been sealed with a well-known PVC membrane. The membrane was literally shattered—a phenomenon known as shattering. Swift action was now imperative to prevent further damage and potential financial losses.
All roof areas, including the undamaged sections, were analyzed, and two renovation concepts were developed. These primarily involved the removal and complete renewal of the damaged roof sections, while the intact areas were preserved with the addition of extra insulation and an additional sealing layer. The plan also included the installation of an emergency drainage system. The execution of the work was entrusted to the certified roofing company Artur Renker Bedachungen from Wuppertal.
Industrial Roof Renovation in the Rhineland – Efficient, Sustainable, and Durable.
The project stakeholders opted for a renovation using large-scale HERTALAN® EASY COVER EPDM membranes, which are characterized by outstanding weather and aging resistance as well as permanent elasticity. As a result, the membranes can even withstand severe hailstorms. The fastening was carried out using an induction process, ensuring wind resistance without penetrating the roof surface.
The decision to forgo a complete demolition of all roof surfaces and instead preserve and reinforce the undamaged sections led to a significant reduction in costs, project duration, and construction waste. As a result, the overall environmental footprint of the renovation project was considerably lower. This was further supported by the partial direct refurbishment on the existing roofing using the circular HERTALAN® sealing system and the return of approximately 400 m³ of saturated mineral wool insulation to the manufacturer for recycling.
In their conclusion about this project, Carsten and Axel Renker agree: “The HERTALAN® membranes, combined with mechanical fastening via induction, are undoubtedly a forward-thinking sealing system. Sustainability is becoming increasingly important for both industrial and private builders. The system not only impresses with its decades-long service life but also with its ability to be dismantled for reuse or nearly pure recycling. Additionally, we are thoroughly convinced by the manufacturer’s qualification programs and the competent, reliable on-site support during construction. This allowed us to safely renovate the total area of approximately 17,000 m². We would gladly do it again at any time!”
