Although there are several ways to frame a "flat" roof,
none of them result in a truly flat roof. Even in mostly
dry Southern California, where I have been production framing
for over 15 years, you have to create a slight slope to get
rid of rain water from the heavy, sudden storms we get.
Otherwise, the water will pond and eventually cause leaks.
To give the illusion of a perfectly flat roof, many designers
add a low parapet around the perimeter of the roof, which
conceals the slightly pitched roof behind. The roof surface is
designed to direct water to one or more drains behind
