Water Puddling or Standing On Flat Roof
Deterioration or leaking may occur if water stands on a roof too long. A little puddling is acceptable provided that it is not too deep.

Gravel voids can cause a roof to leak, shorten it's life expectancy and deteriorate the tar or building paper.
Flat type roofs often have leaves and other debris that gathers on them overtime. If the leaves and debris are not occasionally removed, the drains may get clogged or restricted by the debris. If water builds-up, leaking may occur and if the water builds up high enough, it can cause structural damage.
Blisters on a flat roof may result in leaking if they get popped. Just stepping on them when doing work or maintenance on the roof may pop them.
