On the Properties palette, select or clear Defines Roof Slope. To specify roof pitch, select a slope-defining boundary line, click the numeric slope definition in the drawing area, and enter a value for the slope. You can specify the format of the Slope property in the Project Units dialog.
How do you find the slope of a roof?
The slope of a roof, often referred to as the pitch, is determined by “rise over run” – the roof’s vertical rise in inches for every twelve inches of horizontal length (the run). So a roof with four inches of rise every 12 inches horizontally (run) would have a slope of 4/12 (sometimes displayed as 4:12).
How do you change the slope of a roof in Revit?

What is the average slope of a roof?
The most commonly used roof pitches fall in a range between 4/12 and 9/12. Pitches lower than 4/12 have a slight angle, and they are defined as low-slope roofs. Pitches of less than 2/12 are considered flat roofs, even though they may be very slightly angled.
What is the minimum slope for water flow?
Generally, minimum slope for water to run off is 1% (1/8″ per 1′).
Is a 4/12 pitch roof steep?
4/12 is quite typical. Anything under 3/12 is a low pitch roof. Anything above 6/12 is a steep roof pitch since it becomes harder to walk on the roof.
What does a 4 pitch roof mean?
Roofs require slope for adequate drainage, and even so-called flat roofs must have some incline. A 4/12 roof pitch indicates the roof rises 4 inches in height for every 12 inches, as measured horizontally from the edge of the roof to the centerline.
