Thickness, slope angle, and overhang length of the roof.
Thickness: The thickness of the roof.Slope Angle:
Rise/Run: Specifies the angle of the in standard ratio format. For English units the ratio is X over 12 (X/12). For metric the ratio is X over 100(X/100).
Slope: Specifies the angle of the roof. The higher the angle, the steeper the roof slope. Adjusting this value will alter the Rise/Run.
...
Note: This parameter changes the slope of the entire roof. To change the slope of one facet, use the Edit Slope Angle tool.

The Roof Components properties allow for the setting of different Materials to each component of the roof. The components available are as Top, Bottom, Gable and Fascia
