Revit Roof Modeling Techniques

Introduction

• 23 different roof types are modeled in the video.
• A previous video, covering 10 roof types, was successful.
• Viewers should visit the website for more in-depth Revit courses.

Modeling a Shed Roof

• Use the "Roof by Footprint" tool (Architecture tab, Build panel).
• Adjust the base level (e.g., Level 2).
• Use the "Pick Walls" command for roof selection.
• "Define Slope" is unchecked for simple shed roofs.
• Adjust overhang for preferences.
• Use "Extend into Wall Core" for complex roofs.
• Define roof slope in properties or visually.
• Attach the roof to walls using "Attach Top Base" and the Tab key.

Modeling a Gable Roof

• Simple gable roof modeling.
• Use the "Pick Walls" command, same settings as shed roof.
• Select opposing longer sides and activate "Define Slope."
• Set desired slope, forming lowest points of the roof.
• Attach all walls to the top base after roof creation.

Modeling a Flat Roof

• Use the "Pick Walls" command, setting overhang to zero.
• Activate "Extend into Wall Core" for wall integration.
• Elevate the roof using the top offset option in the properties panel.

Modeling a Hip Roof

• Same "Pick Walls" approach as previous roof types.
• Activate "Define Slope" as all sides have slope.
• Adjust slope as needed.
• Attach all walls to the top base of the roof after creation.

Modeling a Hip and Valley Roof

• Same steps as hip roof.
• Valleys where roof sections intersect.
• Can incorporate gable roof designs for complexity.

Modeling a Jerkin Head Roof

• Start with a hip roof structure.
• Use "Plate Offset from Base" to raise opposing roof sides.
• Creates the distinctive "Jerkin Head" style.

Modeling an M-shaped Roof

• Use the "Roof by Extrusion" tool.
• Select plane to extrude the roof from.
• Define roof level and extrusion start.
• Sketch an "M" shape profile.
• Adjust overhang as needed.
• Press Finish to confirm extrusion.
• Attach the roof to walls.

Modeling a Mansard Roof

• Begin with a larger floor plan.
• Use "Roof by Footprint" tool, adding a set of lines with overhang and defined slope.
• Add another set of lines inside, with a higher slope (e.g., 60-70 degrees).
• Adjust the slope of all lines for the desired steepness.
• Create a second roof for the lower section with a smaller slope.
• Use the Move tool to position the lower roof correctly.
• Attach the roof to the walls using "Attach Top Base".

Modeling a Saltbox Roof

• Build upon a gable roof foundation.
• Use the "Plate Offset" option on one side to adjust elevation.

Modeling a Sawtooth Roof

• Use the "Roof by Extrusion" tool.
• Define plane, desired level, and sketch a repeating profile.
• Use alternating steep and shallow angles.
• Adjust scale if needed.
• Attach the roof to the walls using "Attach Top Base".

Modeling a Dropped Eaves Roof

• Use the "Pick Walls" command, defining overhang and slope.
• Leave "Define Slope" unchecked for remaining sides.
• Creates dropped eaves on the un-sloped sides.
• After creation, attach the roof to the top base.

Modeling a Butterfly Roof

• Favorite design of the presenter.
• Use the "Pick Walls" command with the "Define Slope" option.
• Sketch a butterfly shape.
• Adjust overhang as required.
• Attach walls to the roof's top base.
• Create the dip (butterfly effect) by using a negative slope value and a positive base offset.

Curved Roof

• Create using the "Roof by Extrusion" tool.
• Model an arc on a chosen plane.
• Adjust the arc's shape with offset and angle changes.
• Remove arc ends to create a smooth curve.
• Align the extruded curve with the project.

Clerestory Roof

• Two roof sections joined by a wall.
• Position the wall first.
• Create two separate roofs.
• One roof with overhang and "Define Slope" unchecked.
• Other roof with "Define Slope" activated.
• Trim and extend the roofs to meet at the wall.
• Attach the wall to both roofs.

A-Frame Roof

• Roof that forms a house structure.
• Start with a single level.
• Use the roof tool to make a rectangle.
• Select sides and activate "Define Slope" with a steep slope.
• Add interior walls and attach them to roof and base.

Combination Roof

• Similar to Mansard, with steep top, shallow bottom.
• Create the shallow bottom roof first (e.g., slope 5-10 degrees).
• Then the steeper top roof (e.g., 45 degrees).
• Adjust position in floor plan view.

Cone Roof

• Simple cone shape.
• Use the roof tool, selecting a low overhang and a steep slope angle.

Dome Roof

• Create using a "Dome Mass" family.
• Load the family using the "Insert" tab.
• Adjust diameter and height of the dome mass.
• Position on the appropriate level.
• Convert to a roof using the "Roof by Face" tool.

Dutch Gable Roof

• Gable with an additional gable protruding.
• Create a basic gable roof.
• Leave a gap using "Pick Lines" with offset.
• Create the secondary roof section with "Pick Lines."
• Optionally uncheck "Define Slope" for sides.
• Properly position the second roof section.
• Add a wall to the middle and attach to both roofs.

Pyramid Hip Roof

• Hip roof on a square floor plan.
• Four sloping sides forming a pyramid.

Gambrel Roof

• Combines gable and mansard roof styles.
• Start with a basic gable and overhang.
• Create a gap with "Pick Lines"; extend gap sides and delete middle segment.
• Create a second roof section with a less steep slope (e.g., 20 degrees).
• Mirror the second roof section (using the mirror tool).
• Position the second roof correctly.
• Attach all walls to the base and roof sections.

Hexagonal Roof

• Create a hexagonal floor plan.
• Use the roof tool with "Define Slope" on all sides.

Monitor Roof

• Gable roof with a smaller gable on top.
• Start with a basic gable roof.
• Add a smaller rectangle in the middle of the footprint.
• Create a new roof on top using "Pick Lines".
• Define a slope for the smaller roof section.
• Add walls and attach to the small gable and the base.
