Use the true sloped area — run plan measurements through our roof area calculator first if you only have the footprint. 5% waste suits a simple gable; allow 7.5–10% where hips, valleys and cut-ups eat tiles.
Coverage
9.7 /m²
Nominal tiles per square metre at standard headlap — 65 mm for plain tiles, 75 mm for interlocking.

Tiles to order

Rounded up. Order in full packs and keep the spares for future repairs.
Coverage varies with headlap, gauge, exposure and the exact tile profile — always confirm against the manufacturer's datasheet before ordering. Field tiles only: ridge, hip, valley and eaves fittings are ordered separately.
Tile coverage isn't a property of the tile alone — it's the tile at a particular headlap. The same plain tile covers 60 per m² at a 65 mm lap and needs more at the longer laps used for low pitches and exposed sites. Most bad orders come from using a coverage figure quoted at the wrong lap.
The presets here use standard nominal coverage for the common UK formats. For anything else — pantiles, slate-format interlocking, reclaimed tiles — take the coverage figure straight off the manufacturer or merchant datasheet and use the custom option.
