Common Editing Operations for Revit Roofs
After creating a roof, you can modify its shape or overhang, cut openings, or align the ridge.
Edit Roof Sketch
Select the roof, then click the Modify | Roof tab and choose the Mode panel options: Edit Trace or Edit Profile.
Make the necessary modifications.
If you want to adjust the roof’s position, use the Attributes palette to edit the Bottom Elevation and Bottom Offset attributes, which control the position of the reference plane. If you receive a warning indicating the roof geometry cannot be moved, edit the roof sketch and check for constraints, such as between the elevation line and the roof’s drawing lines.
Click the finish button to complete editing mode.
Adjust Roof Size Using Shape Handles
This method works for roofs created by trace or face. In an elevation or 3D view, select the roof, then drag the shape handles as needed to resize.
Modify Roof Overhang
When editing the roof footprint, you can adjust the overhang by modifying the properties of the roof boundary line. In sketch mode, select the boundary line of the roof.
On the Attributes palette, find the Suspended option and enter the desired value for the overhang.
Click the finish button to complete editing mode.
Cut Openings in a Stretched Roof
Select the stretched roof, then click the Modify | Roof tab and open the Entrance panel (vertical).
If a prompt appears, go to the View dialog box and select the appropriate plan view to edit the roof’s contour.
The plan view of the roof will appear, with the reference plane defining its boundary.
Draw a closed loop to create an opening.
Complete the closed loop sketch in sketch mode, then click the finish button.
The closed loop sketch becomes a vertical section opening in the roof.
Align the Roof Ridge
You can align roof ridges in 3D or elevation views. To align the ridge in an elevation view, use the Align tool.
In a plan view, add a reference plane by navigating to one of the following tabs and selecting Reference Plane in the Work Plane panel:
- Architecture Tab
- Structure Tab
- System Tab
Click to place the reference plane.
In the drawing area, draw a reference plane that is not perpendicular to the ridge.
Select the reference plane and enter its name in the Attributes palette.
Open the 3D view and click Settings in the Work Plane panel, available under the:
- Architecture Tab
- Structure Tab
- System Tab
In the Work Plane dialog box, select the reference plane you just created and click Confirm.
Now, use the Align tool to align the roof ridge.

Create a Conical Roof
If the roof includes a slope defined by an arc or circle, a conical roof will be created. If needed, the arc or circle can be divided into line segments as shown.
In the drawing area, select the arc.
On the Attributes palette, find the option labeled Number of Complete Segments and specify a value.
If you specify zero line segments (default), a conical roof is created.
