Load Application and Compression of Roof Insulation — A Calculation Guide for Flat Roofs on Which Solar Systems Are Installed

The BSW-Solar specialist group for construction technology has been working on the topic of bearing pressure for years. The current paper presents requirements and solutions for the local load-bearing capacity of the roof structure. Special attention is paid to the compressive stress of the insulation below the base rails of the PV system placed on the roof (linear support) or point-shaped supports. The snow load and the necessary ballasting are the decisive factors for the pressure below the supports.
