QUESTION

How do I use the automatic roof tools to create some of the basic kinds of roof styles?


ANSWER

Automatically creating the basic roof styles in Home Designer can be easy using the Roof panel of the Wall Specification dialog. The Pitch value set in the Build Roof dialog only sets the default pitch for all roof planes in a plan. This default value can be overwritten by specifying a different pitch on the Roof tab of an individual wall's Wall Specification dialog.

For this tutorial we will begin by creating a basic 40' x 30' enclosed rectangular structure as in the image below.  Use this basic plan when making the changes on any of the following instructions.


In this article, we will show you how to create the following roof styles automatically:


HIP ROOF

A hip roof has a roof plane built over every exterior wall in the plan that does not have another wall drawn above it, as shown in the image below.

 



To create a hip roof

  1. By default, a Hip Roof will be automatically be created on our 40' x 30' structure without making any changes.


  2. Select Build> Roof> Build Roof  to display the Build Roof dialog.


  3. The Roof panel of this dialog will allow you to change the default Pitch of the entire roof, its Min Alcove setting, and the Roof Overhang values.

    Note: If you are using Home Designer Pro, place a checkmark in the "Build Roof Planes" option at this time. Whenever you want to regenerate the roof planes after making changes to roof directives it is necessary to place a checkmark in this setting unless you have the Auto Rebuild Roofs setting turned on.


  4. Go to the Materials panel to be able to change the default Roof material, as well set the material for that of other roof aspects, such as the Gutter.


  5. Click OK to apply any changes made in this dialog to rebuild the roof with the new settings.

     

    The floor plan view of a standard hip roof will look like the image above.

GABLE ROOF

If a wall does not have a roof plane bearing on it, then it is a gable wall.




To create a gable roof

To create a basic gable style roof, we need to tell the program to not build a hip roof plane over the two 30' walls in our plan

  1. Use the Select Objects  tool to select the left 30' wall to select it, then click on the Open Object  edit tool to display the Wall Specification dialog.


  2. Select the Roof panel, and place a checkmark in the Full Gable Wall option, then click OK.




  3. Follow the same steps for the right 30' wall.


  4. If you have Auto Rebuild Roofs* enabled in the Build Roof dialog, then your plan will update automatically, otherwise select Build> Roof> Build Roof  to display the Build Roof dialog, then click OK to rebuild the roof.

    *Auto Rebuild Roofs is not available in the Home Designer Essentials version of the program, so you will need to build the roof manually using the process above.

    Note: If you are using Home Designer Pro, place a checkmark in the "Build Roof Planes" option at this time. Whenever you want to regenerate the roof planes after making changes to roof directives it is necessary to place a checkmark in this setting unless you have the Auto Rebuild Roofs setting turned on.




    The floor plan view of a standard gable roof will look like the image above.  We have indicated the two walls that should be defined as Full Gable Walls to create this roof style.

SHED ROOF

A Shed Roof is a single, sloping roof plane.

 


 

To create a shed roof

First, we need to tell the program to not build a hip roof plane over the two 30' walls in our plan, set one wall to be a High Shed/Gable wall, and we will also lower the Pitch on the roof so it is not so steep.

  1. Use the Select Objects  tool to select the left 30' wall to select it, then click on the Open Object  edit tool to display the Wall Specification dialog.


  2. Select the Roof panel and place a checkmark in the Full Gable Wall option, then click OK.


  3. Follow the same steps for the right 30' wall.


  4. Finally, use the Select Objects  tool to select the upper 40' wall, click on the Open Object  edit tool, select the Roof panel, place a checkmark in the High Shed/Gable Wall option and click OK.




  5. Next, select Build> Roof> Build Roof  to display the Build Roof dialog.


  6. Set the Pitch (in 12) value to 4", then click OK to apply the change and rebuild the roof with the new setting.

    Note: If you are using Home Designer Pro, place a checkmark in the "Build Roof Planes" option at this time. Whenever you want to regenerate the roof planes after making changes to roof directives it is necessary to place a checkmark in this setting unless you have the Auto Rebuild Roofs setting turned on.





    The floor plan view of a standard shed roof will look like the image above with a single roof plane.  We have indicated the two walls that should be defined as Full Gable Walls, and the wall that should be specified as a High Shed/Gable Wall, to create this roof style.


GAMBREL ROOF

A gambrel, or barn style, roof has two pitches on each side of the ridge.  The first (lower) pitch on either side is steeper than the pitch near the ridge.



 

To create a gambrel roof

To create a basic Gambrel Roof, we need to tell the program to not build a hip roof plane over the two 30' walls in our plan, as well as to set the appropriate Lower and Upper Pitches for the two 40' walls.

  1. Use the Select Objects  tool to select the left 30' wall to select it, and click on the Open Object  edit tool to display the Wall Specification dialog.


  2. Select the Roof panel, and place a checkmark in the Full Gable Wall option, then click OK.


  3. Follow the same steps for the right 30' wall.


  4. Use the Select Objects tool to select the upper 40' wall, click on the Open Object edit tool, select the Roof panel, and specify the Lower pitch as 24" in 12.


  5. Place a checkmark in the Upper Pitch option and set its pitch as 6" in 12.


  6. Change the In From Baseline value to 60" so that the second pitch will begin 5' in from the top plate.

    The Start at Height will adjust automatically based on the other values entered.




  7. Click OK to apply these changes and close the dialog.


  8. Follow this same procedure for the remaining 40' wall.


  9. If desired, experiment with alternate pitches and overhangs. Also, try varying the height at which the second pitch begins so that you can see the effect it has on your gambrel roof design.


  10. If you have Auto Rebuild Roofs* enabled in the Build Roof dialog, then your plan will update automatically, otherwise select Build> Roof> Build Roof  to display the Build Roof dialog, then click OK to rebuild the roof.

    *Auto Rebuild Roofs is not available in Home Designer Essentials version of the program, so you will need to build the roof manually using the process above.

    Note: If you are using Home Designer Pro, place a checkmark in the "Build Roof Planes" option at this time. Whenever you want to regenerate the roof planes after making changes to roof directives it is necessary to place a checkmark in this setting unless you have the Auto Rebuild Roofs setting turned on.





    The floor plan view of a standard gambrel roof will look like the image above.  We have indicated the two walls that should be defined as Full Gable Walls, and other two walls that need to have the Upper, Lower Pitch and distance in From Baseline to create this roof style.

GULL WING ROOF 

A gull wing style roof has two pitches on either side of the ridge, where the first pitch is shallower than the second.

 

 

To create a gullwing roof

First, we will need to tell the program to not build a hip roof plane over the two 30' walls in our plan as well as to set the appropriate Lower and Upper pitches for the two 40' walls.

  1. Use the Select Objects  tool to select the left 30' wall to select it, and click on the Open Object  edit tool to display the Wall Specification dialog.


  2. Select the Roof panel and place a checkmark in the Full Gable Wall option, and click OK.


  3. Follow the same steps for the right 30' wall


  4. Use the Select Objects tool to select the upper 40' wall, click on the Open Object edit tool, select the Roof panel and specify the Lower pitch as 6" in 12.


  5. Place a checkmark in the Upper option and set its pitch as 12" in 12.


  6. Change the In From Baseline value to 60" so that the second pitch will begin 5' above the top plate.




  7. Click OK to apply these changes and close the dialog.


  8. Follow this same procedure for the remaining 40' wall.


  9. If desired, experiment with alternate pitches and overhangs. Also, try varying the height at which the second pitch begins so that you can see the effect it has on your gambrel roof design.


  10. If you have Auto Rebuild Roofs* enabled in the Build Roof dialog, then your plan will update automatically, otherwise select Build> Roof> Build Roof  to display the Build Roof dialog, then click OK to rebuild the roof.

    *Auto Rebuild Roofs is not available in Home Designer Essentials version of the program, so you will need to build the roof manually using the process above.

    Note: If you are using Home Designer Pro, place a checkmark in the "Build Roof Planes" option at this time. Whenever you want to regenerate the roof planes after making changes to roof directives it is necessary to place a checkmark in this setting unless you have the Auto Rebuild Roofs setting turned on.





    The floor plan view of a standard gull roof will look like the image above.  We have indicated the two walls that should be defined as Full Gable, and other two walls that need to have the distance in From Baseline to create this roof style.

    Notice that in floor plan view, this roof style can look identical to the gambrel roof, so it is important to verify that you have your upper and lower pitches set correctly, and verify with a camera view.

HALF HIP ROOF

A half hip roof has two gable ends, but at the top of each gable is a small hip that extends to the ridge. It is a combination of gable and hip roof styles in which a hip roof plane builds upward from a partial gable wall.

 


  

 

To create a half hip roof

We need to tell the program to not build a hip roof plane over the two 30' walls in our plan

  1. Use the Select Objects  tool to select the left 30' wall to select it, and click on the Open Object  edit tool to display the Wall Specification dialog.


  2. Select the Roof panel, and place a checkmark in the Full Gable Wall option


  3. Check the box next to Upper pitch, then specify the Upper pitch as 3" in 12.


  4. Set the In from Baseline value at 108" and click OK.




  5. Follow the same instructions for the right 30' wall.


  6. If you have Auto Rebuild Roofs* enabled in the Build Roof dialog, then your plan will update automatically, otherwise select Build> Roof> Build Roof  to display the Build Roof dialog, then click OK to rebuild the roof.

    *Auto Rebuild Roofs is not available in Home Designer Essentials version of the program, so you will need to build the roof manually using the process above.

    Note: If you are using Home Designer Pro, place a checkmark in the "Build Roof Planes" option at this time. Whenever you want to regenerate the roof planes after making changes to roof directives it is necessary to place a checkmark in this setting unless you have the Auto Rebuild Roofs setting turned on.



     


    The floor plan view of a standard half-hip roof will look like the image above.  We have indicated the two walls that should be defined as Full Gable Walls, and other two walls that need to have the Upper Pitch and distance in From Baseline to create this roof style.

    The top and bottom walls can be left at the default value set in the Build Roof dialog for their pitch.

MANSARD ROOF

A mansard roof is a hip roof with two slopes on the roof sections above each of the four walls. The second slope begins at the same height above each wall. The upper slope is usually quite gentle and the lower slope, much steeper.

 


 

To create a mansard roof

To create a Mansard style roof, we will need to change the Roof tab of the Specification dialog for all four walls in the .plan file.

  1. First, using the Select Objects  edit button, select the left wall and click on the Open Object  edit tool to display the Wall Specification dialog.


  2. On the Roof panel:



    • Under the Pitch heading, specify a Lower pitch of 24"

    • Place a checkmark next to Upper and specify a pitch of 1/4"

    • Put 60" for in from Baseline value.


  3. Click OK, and repeat this process for the remaining three walls in the plan.


  4. If you have Auto Rebuild Roofs* enabled in the Build Roof dialog, then your plan will update automatically, otherwise select Build> Roof> Build Roof  to display the Build Roof dialog, then click OK to rebuild the roof.

    *Auto Rebuild Roofs is not available in Home Designer Essentials version of the program, so you will need to build the roof manually using the process above.

     


    The floor plan view of a standard mansard roof will look like the image above.  We have indicated that all four walls should have their Upper and Lower Pitches defined, along with an in From Baseline distance, to create this roof style.
