Interlocking roof tiles

[puntloos]

So I'm quite tempted to go for the interlocking roof tile - it's quite cost effective for what you get, and it seems elegant enough... 

 

But am I missing ay downsides?

 

FWIW th tiles I'm primarily thinking of are:

 

Forticrete Minislate

Edgemere Concrete roof tiles

Not sure if it is a locality thing but in fenland concrete tiles age badly and very quickly,  driving down any road you can easily spot concrete,  clay , slate just by the thickness of crap sitting on top of the tiles.

We went with a slate-effect interlocking clay tile. Much harder smoother surface than concrete, thinner edge, much more slatey-looking

My roof is done with Edgemere Riven finish.  It's a slightly thinner version of the standard Edgemere tile and with a riven finish to make it look just a little bit like slate.  It was the only concrete tile that the planners would accept here having tried to get me to use slate.

Availability might be a consideration. Few years ago it was easier to get hold of clay

We specified Sandtoft 20/20 interlocking clay tiles in ‘Antique’ for a forthcoming project.  Dark grey / black clay.
