Flat/Low Slope Roof

Flat/Low Slope Roofing

A roof that is nearly flat or slightly pitched is called a flat roof or low slope roof – No roof should be dead flat because it must have at least a slight slope to drain. … This means that for every horizontal foot, the roof level goes up less than 3 inches vertically.

Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof. Flat roofs, or “low–slope” roofs, are also commonly found on commercial buildings throughout the world.
