The angle made by the roof surface plane with the horizontal plane and expressed as the amount of vertical rise for every twelve inch (12") horizontal run. For instance, a roof that rises four inches (4") for every twelve inch (12") horizontal run, is expressed as having a "four in twelve" slope; often written as "4:12." Expressed as a percentage, the slope would be 33%, which is equal to 4 divided by 12. Also known as the Pitch of a roof. For more information on Roof Slope, click here.
The angle of roof incline expressed as the ratio between the rise (in inches) and run (in inches). Example: a roof that rises 4" for every 12" of run is expressed as 4:12. Run: The horizontal distance from the eaves to the point directly under the ridge.
The angle formed by the roof surface plane with the horizontal plane of the building. Expressed as the amount of vertical rise for every twelve inches of horizontal run. For example, a roof that rises four inches for every twelve inch (12") horizontal run, is expressed as having a "four in twelve" slope; often written as "4:12." Expressed as a percentage, the slope would be 33%, which is equal to 4 divided by 12. Also referred to as the Pitch.
The angle a roof surface makes with the horizontal, expressed as a ration of the units of vertical rise to the units of horizontal length (sometimes referred to as run). For English units of measurement, when dimensions are given in inches, slope may be expressed as a ratio of rise to run, such as 4:12 or as a percent.) See SLOPE.
The angle that a roof surface makes with the horizontal. Usually expressed in units of vertical rise to 12 units of horizontal run.
The angle generated by the comparison between the roof surface and the theoretical finished floor of a building. Typically expressed in inches of vertical rise to 12 inches of horizontal run.
The ratio of rise to base width, usually expressed in inches of vertical rise to 12 inches of horizontal run.
also called the pitch, is the ratio of the rise of the roof to the run of the roof, (i.e. - a roof with a 6 foot rise for every 12 foot of run is a 6/12 pitch, or 22.5 degree slope).
The angle or steepness of a roof. Typically expressed as a certain rise over each 12 inches of run - for example, a 6 on 12 roof rises six inches for every twelve inches of run. Also called Roof Pitch.
