Degree of roof slant stated in inches rise per foot. The angle
at which a roof slopes. The slope of the roof. The degree of
slope in a roof. Describes the slope or angle of a roof. The
pitch is calculated by the number of inches it rises vertically
for every 12 inches it extends horizontally. Ratio of rise to
width. Angle of the roof sides expressed in a ratio of span to
rise. The tangent of the angle that a roof surface makes with
the horizontal, usually expressed in units of vertical rise to
12 units of horizontal run. The degree of a roof's slope. Inches
of rise per 12: of roof run. Inches of rise per foot of run. For
example, a 45-degree roof has twelve inches of rise for each
foot of run and is therefore called a "twelve pitch" roof. Angle
of inclination with the horizontal of the structure on which
roof coverings are laid. (Low pitch = 4-10Â°, very low pitch â‰¤
4Â°). The angle or slant of a roof surface. The angle or
steepness of a roof. Typically expressed as a certain rise over
each 12 inches of run
