A defective roof covering with permanent water ingress, which had already damaged the roof and supporting structure in some areas, impaired the daily use of the Interspar RUM supermarket in Innsbruck. The requirements for a roof renovation: A new, durable roof covering adapted to the climatic conditions (snow, ice & wind) as well as the upgrading of the safety equipment on the roof according to current standards. In search of a complete solution including structural analysis, building physics, works planning, site concept and on-site production, the choice fell on BEMO and its 360° Service.
