But such a low slope holds snow and water much longer than a steeply pitched roof and therefore needs a very different material to stay watertight.

To add a pitched roof to something as large as a mall or other similar sized edifice would be incredibly costly and it s just easier to stick with a flat roof in those cases. Commercial roofs are flat roofs because they are much more cost effective compared to pitched roofs. Shingling these types of roofing systems is usually not a good idea. By far the biggest advantage of using a flat roof is the expense.
