Roof Tile Calculator
Work out how many roof tiles you need from the roof area and the tile type. Use the true (sloped) area — get it from the Roof Area Calculator — and add a breakage allowance and the ridge tiles.
Ridge/hip tiles are counted at about 3 per running metre.
Clay tiles break in handling & laying; 5–10% is typical, more for country tiles.
mangalore (interlocking clay) · incl. 10% breakage.
Buy a little extra and keep spares from the same batch — colours drift between batches, and you will want matching tiles to replace breakages over the years. See the clay roof tiles guide.
A planning estimate. Coverage (tiles per m²) varies by maker and profile — always confirm the exact figure from the manufacturer’s data sheet before ordering, and take off the ridge/hip lengths from the drawings. Fixing a tiled roof is work at height for a roofing contractor.
