For flat roof drainage where you place your drains scuppers and the final material of the roofing is more important.
Sloped roofs simply drain water and snow better than flat roofs.
The main benefit of inner drains is that the system is hidden from view.
To keep damage like leaks from occurring water should not stand on a flat roof for more than 48 hours.

It s just a matter of gravity because water and other substances are going to pool on a flat roof since there isn t anywhere for it to flow.
The slope should be a minimum of 1 in 80 but in practice a minimum slope of 1 to 40 should be used to allow for deflection of the roof and for normal building tolerances.
Each of these systems has its own pros and cons.
It s the most popular drainage system for the average roof.
For clarity flat roofs actually have a slight slope to allow rain water to drain off the roof but they seem flat when compared with more traditional steeply sloped roofs.

Poor drainage can lead to serious issues with flat roofing from leaks to structural damage.
