Alongside Cromar’s flat roof coatings, we stock both new and reclaimed tiles for pitched roof work — new stock for full re-roofs and extensions, reclaimed tiles for matching an existing roof exactly.
Concrete and clay tiles for full re-roofs, extensions and new builds.
Browse New TilesSalvaged tiles for repairs and extensions that need to match an older roof.
Browse Reclaimed TilesBring a sample tile or a clear photo in to the yard and our team will help you match it, or source the closest equivalent if we don’t have it on the shelf. Stock changes regularly, so it’s always worth calling ahead for reclaimed tiles in particular.
