These types of roofs have special requirements. Unlike steep-sloped roofs, which rely on gravity to shed water, flat roofs depend on drains and rely on a waterproof membrane to protect the property. Actually, the term 'flat' is misleading here — no roof should be completely flat or you'd find yourself living under a small lake. "Low slope" is a more accurate description of what's commonly called a flat roof. Low slope roofs should have at least a 1/4 inch of slope per foot (preferably more) so that water can flow downhill to drains and then to the ground.
