Hi,

Would simply leaving the bottom board off the attic, and replacing with
a shorter one, so there is a small gap work?
(obviously there would have to be a carrier over this to keep the tar-paper
off and provide a vent.)

Difficult to know without seeing a picture. It might be well worth
finding a local roofing specialist and paying them for an hour of
advice, if you're going to spend a lot of time and money on this.

Probably wise, thanks.

If the roof was insulated with polystyrene or similar boards on the top,
would this not greatly help?

It's easier to add insulation above the ceiling if you're not using
the loft space as a room.

The entire roof (at the very least one side) needs re-doing.
So, all the slates/tar-paper are going to be up, and the bare boards are
going to be available.

That was why I was wondering if it might not be a good idea to stick a
layer of insulation in at that time, to allow the option of using the
attic as a room, plus to increase the insulation of the whole house
by the attic warming up a bit.

All that needs doing is relatively minor work round the edges...

If the attic was to then be converted into a room, there would be the
option of also adding insulation inside, for really good insulation.
(paying attention to proper ventilation to avoid condensation)
