This would depend entirely on the definition of flat, and its origin. Flat rooofs are not flat, and all should have enough slope to run water, generaly 1 to 2% minimum. In our area a flat roof is defined as any roof with less than 3:12 pitch and must have Ice and Water shield or other equivelant materials installed to prevent damage. Usually up to and including a 2:12 Pitch can be protected with a Build Up Roofing system or BUR roof. Another usual material is what we call a Single Ply or Membrane roof. These materials are like a big rubber inner tube being pulled over the roof and can be attached with ballast (rock) or mechanically. Most today are a white material but collored are available from some manufactures. ALWAYS check with your local building official for the actual definition and requirements in your area. Terry

A flat roof is a maintenance nightmare year after year. So many people have made that mistake only to later put a pitched roof over the flat roof to avoid any more hassle.

Those who live in a building with a flat roof have advantages and disadvantages. A flat roof will not cause as many problems with gutters as a sloped roof would. It is also possible to shovel snow right off of the flat roof. However, it is also possible to have too much snow accumulate on this type of roof which can cause a cave-in or sagging. A flat roof may leak more from too much rain. However, in the extreme cold weather, icicles are not much of a problem with a flat roof. Since the water from the snow doesn't drip down as much as on a sloped roof, the icicles don't have a chance to form.
Having a flat roof is more common where there are occasional downpours, but not in regions that are considered rainy. The reason is that the flat roof will hold rain pools causing damage to the roof itself.
