CROSS Safety Alert
Snow loads on agricultural and other building structures
Snowfalls in 2010, and in the early part of 2011, caused a significant number of agricultural and associated buildings in Scotland, and a small number in the North of England, to partially fail or to collapse.
The likely causes include the build-up or drifting of snow on roofs, the age of the buildings, weaknesses in original design or construction, and lack of maintenance. In some cases, snow depths of 50-60cm on roofs were reported.
Note: this Safety Alert was published by SCOSS (Standing Committee on Structural Safety). Since March 2021, SCOSS is integrated under the name Collaborative Reporting for Safer Structures (CROSS).
