I am trying to create a blended extruded roof or ceiling element in Revit. As far as I can tell, this isn't possible. I created a generic model and used a extruded blend which works but I wanted to see if there was a way that I could make it so it is recognized as a roof or ceiling that walls will connect to?

Sure it's possible with Variable Thickness Layer and shape editing using Modify Sub-Elements tool.
Create a Mass for your blended shape.
Then use Roof by Face, create roof.
Then attach walls to roof.
Can you post an image of the shape of the generic model?
Hi @Anonymous
Do you have an image of the roof or something similar that you would like to re-create in Revit. It will help us guide you better.

Example workflow:
1. Open Edit Assembly dialog box for an OOTB Basic Roof Type, such as Basic Roof: Generic 9".
2. Make the Structural layer a variable thickness layer (e.g. place a check in the "Variable" box)
3. Create a flat roof slab using that Roof Type (e.g. DO NOT define any slope)
4. Select the flat roof slab and click Modify Sub Elements from the Contextual Tab.
5. Shape the roof into your "sweep blend" shape using Shape Editing.
Hi @Anonymous
Below is a screencast for creating a sweep blend roof:
Steps:
Open a project.
On the ribbon, click (Model In-Place).
Architecture tab: Build panel-Component drop-down (Model In-Place)
In the Family Category and Parameters dialog, select a Roof category for the element, and click OK.
Create a Swept Blend Form
The shape of the swept blend is determined by the starting shape, the ending shape, and the 2D path that you specify.

@Viveka_CD: Well, in that case, @Anonymous could do the same thing with a mass and apply his roof type to its faces.
Bottom line: a sweep-blend roof is achievable with Revit.
Yes, I agree with you @barthbradley
It's the OP's choice on how he intends to create this roof.

Yep--just like I mentioned............![]()
Aside from using a mass and roof by face, you can join walls to in-place roof if you want to keep what you already have done.
you are telling that you have already done it as generic model.
all what you need to do is change the category to roof or ceiling.
check below shot.
