roof
Let an agent handle roofs by form, material, condition, safety of work at height and energy performance.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle roofs by form, material, condition, safety of work at height and energy performance.
The covering on the top of a building or structure that protects it from weather, with forms such as pitched, flat, domed and hyperbolic-paraboloid roofs, and materials such as tile, slate, metal or thatch.
What it is for: Keeping weather out and supporting insulation, solar panels and drainage.
It can be inspect and repair it; insulate it; install solar panels, with checks; work on it safely at height.
Distinguishing features
Top covering of a structure
Form and material decide performance
Work on roofs is work at height
Key to energy efficiency
What it looks like
The top covering of a building: pitched with tiles or slates, flat with membranes, metal sheets, thatch or green roofs; shelters have simple roofs.
Physical character
pitch: 0-60 degrees - flat roofs have small falls
design snow load: 0.5-5 kN/m2 - depends on location
How it is recognised
Roof form and covering
Gutters, flashings and chimneys
Twisted spires and special forms

Work safety
Safety measures.
- What fall protection is required for roof work? boundary
- Should a professional do it? action
Fragile surfaces
Rooflights.
Fragile
Fragile surfaces.
- Are there fragile rooflights or sheets? boundary
- Are they marked? boundary
What the second pass must settle
- Should roof types be separate entries?
- How should roof condition be recorded?
- The registry entry has merged aliases such as public transport shelter; should they be split off?
