BASIX recognises the following roof types:
Flat ceiling and pitched roof
- Pitched roof (slope > 10°) with roofspace
- Flat/horizontal ceiling
Raked ceiling / Pitched or skillion roof
- Pitched or skillion roof (slope > 10°)
- Ceiling lining parallel to roof
Flat ceiling / Flat roof
- Flat roof (slope ≤ 10°)
- Flat/horizontal ceiling
Tip: Providing roof insulation will reduce your ceiling insulation requirements.

If your dwelling has another dwelling above (such as a granny flat), you are not required to describe the ceiling and roof type. If the dwelling has part of the ceiling with a dwelling above and part with a roofspace above, describe the ceiling with a roofspace above only. |
