Question concrete tile roof insulation

We are considering the purchase of a house with a 25 yr old tile roof made of concrete. From the attic, we cannot see any sign of insulation, just tiles and even a lot of light between the tiles.

Can this possibly be waterproof? There is insulation on the floor of the attic but nothing underneath the tiles. You can actually touch the tiles while standing in the attic.

Please any information would be helpful.

Roof insulation

It is not recommended that the underside of the roof be insulated. Insulation is placed on attic floor to keep heating in the rooms below. Insulating roof will trap heat and humidity in attic and result in moisture problems.

Question

Interesting! Now about question: Much of the house has open beam ceilings and we can see evidence of water damage along several of the beams. Would you at least install the tiles over black roofing material (don't know what you call it ) used with conventional shingles?

nothing goes under the tile, all the holes that you see are part of the ventilation for the attic. as to water damage, ask the owner, if you are a serious buyer, they cant withold info anymore. g/l
