What is the cheapest roof to get?!

[ellythefish]

I have planning permission for an agricultural building to replace the roof with new box profile sheeting and turn it into a cafe.

Someone just mentioned to me that concrete tiles might be cheaper! Is this true? Any info on how much it roughly costs per meter square for tiles vs sheeting would be much appreciated as I cant find out this on google anywhere, and although i could find some tile prices i cant find out how many tiles you would need per meter square to start with!
All the tile companies assume you knwow these things.

thanks!

Concrete interlocking tiles start at approx £6 / m2.

You'll need to consider the construction though. is the building traditional construction (i.e. rafters) or steel frame (i.e. purlins). It might cost more to create a structure onto which tiles can be fixed than to install sheeting if its the latter.

For the non-trade buyer decent concrete tiles pan out at between £1 to£1.50 each. It's normally about 10 tiles to a square metre and the weight is about 50Kg per sqm. You need to add in the weight of battening, felt and any other sub-structure needed.

The Marley and Redland websites will give you precise information.

Box profile sheeting would probably be the cheapest option, as you can get it made to measure up to a certain length, it also comes doubled skinned with the foam insulation between the sheets so it is only a matter of screwing the sheets on with a screw gun.

Cheapest roof may well be a pole in each corner & a tarpaulin
