How do you slope a flat roof for drainage?
For drainage purposes, the current building codes require a minimum two percent slope or a one-fourth unit vertical for every 12 units horizontal. In other words, the roof must slope one-fourth of an inch for every 12 inches. The slope is barely noticeable to the naked eye.
How do flat roofs drain rain water?
What do Drainage Systems do? A low-slope roof tilts slightly downhill from its center or from one side, so water rolls off to parapet scuppers and down the hopper (downspout). The scuppers are the openings in the outside walls, specifically designed to allow water, but not debris, to wash off your roof.
What is a scupper gutter?
Scupper Gutters are used to provide an outlet through parapet walls or gravel stops on flat and built-up roofs to drain excess water. They can use them in conjunction with gutters and downspouts to divert the flow to the desired location.
Do gutters have to be sloped?
Without the gutter slope, water will simply pool in your gutters and will not flow towards the downspouts. Too much of a slope poses its own problems, however.

Do roof drains need to be insulated?
Storm water piping is also susceptible to condensation and should be insulated from the roof drain bowl to a point where the piping turns from horizontal to vertical. In any event, the storm water piping should be insulated for a minimum of 30 ft. from the roof drain.
Where do flat roof drains go?
Drainage pipes are placed under the roof or in the parapet wall to make sure that the space looks good and no pipes are visible. This drainage system is usually placed in the centre of the roof or where the slope is directed. These are most appropriate for large roofs.
