What it is Filled

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.

Why it exists Filled

Let an agent handle roofs by form, material, condition, safety of work at height and energy performance.

Distinguishing features Filled

  • Top covering of a structure
  • Form and material decide performance
  • Work on roofs is work at height
  • Key to energy efficiency

What robots and AI may and may not do Filled

Must not

  • Send people onto a roof without fall protection.
  • Work on a roof in high winds or ice.
  • Remove or disturb roofing that may contain asbestos without proper procedures.
  • Overload a roof with equipment beyond its rating.

Only with a human decision

  • Ordering roof repairs or replacement.

May

  • Inspect a roof by drone or sensor and report damage to the owner.
  • Monitor snow load and drainage for the building manager.

Moral aspects Filled

  • Roof work causes many fatal falls.
  • A failed roof exposes occupants to the weather and collapse.

Who is affected

  • Occupants
  • Roofers and workers
  • Passers-by below

Owners Filled

Steward

The building owner.

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.roof
  • Wikidata: Q83180 (https://www.wikidata.org/wiki/Q83180)

Direct properties required Filled

  • pitch: 0-60 degrees - flat roofs have small falls
  • design snow load: 0.5-5 kN/m2 - depends on location

Recognition required Filled

  • Roof form and covering
  • Gutters, flashings and chimneys
  • Twisted spires and special forms
  • The top covering of a building: pitched with tiles or slates, flat with membranes, metal sheets, thatch or green roofs; shelters have simple roofs.

Capabilities and actions required Filled

  • inspect and repair it
  • insulate it
  • install solar panels, with checks
  • work on it safely at height

Hazards and failure modes required Filled

  • Falls during roof work
  • Leaks and damp
  • Storm damage
  • Snow load collapse

Standards and interfaces required Filled

  • Building codes on roofs and loads
  • Work at height regulations
  • Fire classification for roof coverings (EN 13501-5)

Context of use required Filled

  • Keeping weather out and supporting insulation, solar panels and drainage.
  • pitched roofs
  • flat roofs
  • domes and shells
  • green roofs
  • thatched and traditional roofs
  • shelter roofs

Sources Filled

  1. Wikidata item Q83180: roof - identity and sense of the item
  2. Wikipedia: Roof - general description of the item

Open questions

  • 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?
