The first concrete interlocking tiles to be introduced to the market, they are cheap, simple to lay and resistant to adverse weather conditions. These tiles have two channels, either smooth or granular in finish and are available in a variety of colours. However, the Redland 49 is cambered whilst the Marley Ludlow is flat. These tiles cannot be laid together due to a difference in how they interlock, yet can be laid on the same roof providing they are on separate slopes.
