On Mon, 01 Nov 2004 10:20:50 +0000, a particular chimpanzee named The
Natural Philosopher randomly hit the keyboard and produced:

You can either insulate the ceiling joists, in which case we need to
know the dimensions of them, or you can turn your 'cold roof' into a
'warnm roof. which is more than just laying down some insulation stuck
between the rafters.

A lot more. In fact, completely stripping the felt, battens and
tiles, insulating OVER the rafters, then counterbattening over that.

A warm roof is NOT one where any part of the rafters are below the
internal temperature of the building.
