Smooth tile

Has anyone perhaps found a smooth roof tile/flat tile that is cheaper than the Röben roof tile Bergamo? This costs approximately €13/sqm. We would really like to have smooth tiles, but the cost is about €10k extra on our house. Thank you!

Does your roof have 2,000 m² or something in that size range?

I don't quite understand it either. Is it about the roof covering of a municipal utility building/hospital etc.? There are GU/GÜ prices that are outrageous, but THAT?

For approximately 2,000 sqm and if the cheapest standard tile/brick is included, it would be reasonable. I suspect the roof is more like 150 sqm and the price is more like 13 times overpriced?

Hi, it looks like the client made a mistake with the price in the contract - thank you for showing me that! :D
