I'm trying to understand difference between roofing method/material for my extension kitchen but can't find any in mentioning.

Its 22*10 ft extension, I've allocated 6 x 10ft for skylight glass roofing on the right side which is supposed to be closed yard concept, but not sure what roofing for the inner part of kitchen, cement vs roof tiles?

Any recommendation on pros and cons of each? Or maybe no difference, just design?
