How this is worked out
Roof area is multiplied by the tiles per square metre figure for your tile, then by any waste allowance, and rounded up.
Worked example
- Roof area 60 m²
- 10.5 tiles per m²
- No waste allowance
60 × 10.5 = 630
630 tiles
Assumptions and limits
- Tiles per square metre depends on the tile and the batten gauge used, so take the figure from the manufacturer rather than the default.
- Ridge, hip, verge and valley tiles are counted separately.
