Roof Assembly Naming

The roof assembly naming structure will follow the Assembly Naming Template
Reference Assembly Naming- Walls, Floors, Ceilings, Roofs for more information

Flat & Low-Sloped Roofs:

Modeled as a single element in Revit with variable truss layer, causing all layers above the truss to follow the truss slope. The layers below the truss will stay flat. The slope is achieved through points.
Per Andrew and Jeff, in cases where the is a low slope (flat) roof, the top cord of the truss will be sloped as a Forum default . The alternative is to slope the top insulation (Other possibilities exist).

Pitched Roofs:

Modeled as two elements in Revit, using two assemblies: one for the roof and one for the ceiling. Revit requires separate modeling for pitched roofs and their corresponding ceilings.
Pitched Roof Assemblies contain a Revit Roof and a Revit ceiling with identical names for consistency and tagging.
Example: While the roof and ceiling names for RW-1 are the same in Revit, the roof is comprised of asphalt shingles, membrane, sheathing, and a top chord of truss. The ceiling is comprised of the bottom chord of truss, batt insulation, resilient channels, and gypsum board. Both the roof and ceiling make up the RW-1 assembly.

Ceilings:

The first 'Structure' layer of the ceiling typically corresponds to the bottom chord of the truss, usually constructed using 2x4's, resulting in an actual thickness of 3.5 inches.

Assembly Name: RW05-2HR-INT(SHTG)-INT(GYP)

Per Andrew, RW-5 is used primarily as a "horizontal assembly" to cap a 2-hour shaft or room and very rarely as a roof, so it does not need roof finishes.
RW-5 is considered a ceiling only and does not have a corresponding roof in Revit
