Updated 2026 · Independent cost guide
Tile coverage is set by how many of each tile fit in a square metre, which depends on the tile type and how it is gauged. Enter your roof area and pick a tile and this works out the tiles, ridge tiles and battens you need, plus a wastage margin so you do not run short halfway up the roof.
How many tiles do you need?
Estimate for ordering and quote-checking. Coverage depends on the exact tile and the batten gauge your roofer sets, so always confirm against the manufacturer’s fixing data for your chosen tile.
