Blistering, bubbling, or cracking

On a warm day, this moisture gets heated up as it’s traveling through from above or below the roof surface. The heat makes the volume of water to exceed the permeability of the roof’s coating film or roof ply, which forces the coating to separate at its weakest points, creating blisters. 

Sagging

A sagging flat roof ceiling is a result of a change in your roof’s surface level. It usually emanates from moisture accumulation or added weight to the flat roof. If a flat roof carries more weight than it’s intended to, the structure will inevitably dip.
