Should a flat roof be perfectly flat?
No. It normally needs designed falls to move water towards drainage points.

Flat roof pooling water: is it a problem?
Some flat roofs retain small amounts of water temporarily, but persistent deep ponding can indicate falls, outlets, deflection or drainage issues.
What to do next
A sensible first check
✓ Observe how long water remains after rain
✓ Check outlets from a safe location for obvious blockage
✓ Look for internal staining or membrane damage
✓ Do not walk on a roof to inspect it unless competent and safe
When should you act?
Persistent ponding combined with leaks, sagging or visible membrane distress should be assessed.
This page is general guidance, not a diagnosis. If the issue involves immediate danger, active water near electrics, fire, gas, structural instability, unsafe working at height or another urgent safety risk, use an appropriately qualified professional or emergency service rather than relying on online advice.
