Underestimation of snow loads can result in premature failure, high maintenance costs, resource damage, and, in some cases, safety issues. Don't know what this translates to in terms of depth of snow, but what is more critical is the way the snow behaves - if an initial coat has slightly melted and then turns to ice, and then is overlain by a second coat, then 'depth of snow' is irrelevant.

The snow map, which has been reproduced in Figure 1, divides the country into a number of zones, according to the predicted intensity of the 1 in 50 year snow event. A revised UK and Eire ground snow load map has been produced building on an EC funded European Research Group study. Typically for the UK the average design wind load is 1200 N/m2 and the snow load 600N/m2 however using the average may cause the glass to be over specified or even worse underspecified for the task.
