In general, roofing and roofing materials are characterised as being 'low-slope' or 'steep-slope.' Low-slope is generally considered in the industry as a roof with a 'rise-over-run' of two feet in 12 ('2:12') or less. (Flat roofs are de facto considered to be in the 'low-slope' category). Steep-slope would be any roof with a rise-over-run relationship of greater than 2:12 (>10[degrees]). In general, steep-slope roofs are far more common in residential applications, while low-slope roofs are more common in commercial applications, although this is certainly not a hard-and-fast rule.
