Interlocking roof tiles

[Nat_]

Hello.

I need to replace a couple of broken concrete tiles on my roof. The problem is that there is no make's stamp on their backs.

They look like Marley ludlow, Redland renown and Sandtoft lindum, but all of those have their stamps. 

Shall I then just measure the size and look for the identical profile and measurements? 

Thanks

Post a picture or two so we can get an idea what they might be.

Are they Redland 49?  Take one off and along to a roofing supplier to match.

They certainly have a Redland 49 look about them. but as @Mr Punter says, find a roofing supplier and take a sample along to match up.

From memory the Redland 49's are slightly curved, they look like Marley Ludlow Plus to me, which are flat from top to bottom

That is exactly what I thought: Redlands are bit curved and mine are not. Thank you.
