Flat roofing systems are those with an extremely low level of pitch (just enough to facilitate drainage). These are largely popular among industrial and commercial structures, perhaps because they are generally more durable (especially for large spaces), can accommodate structural changes fasters, and are much easier to install and maintain. That being said, residential homeowners are also known to use them - albeit in lesser numbers and most typically in arid to semi-arid regions.
Flat roofs have certain key characteristics that make them stand in stark contrast to pitched or sloped roofs. This includes a low, almost-flat slope (generally less than 1 inch and a maximum of 2 inches) per foot, specific drainage systems (like downspouts, gutters, or scuppers) integrated within the roof), the presence of insulation and reflective coatings and the presence of secondary equipment such as HVAC units, solar panels or other electricals. These roofs are typically made from materials that can maintain their tensile strength, do not band, and prevent the accumulation of substances such as bitumen, PVC, TPO and EPDM.
