It could easily be that there is a *lot* of water in your typical roof. Certainly the water is far from pure, so it's going to be pretty low conductivity.

there's also an amazing amount of metal and other junk in the usual 
composition roof construction.  Nails to hold the shingles on, for instance.

But I think the major absorption will be the moisture in the wood sheathing.

By this logic, a thatch roof in a dry climate is the best thing going.
