You could insulate under the roof rather than over the ceiling. My loft
storage has the roof insulated precisely because the above-ceiling
insulation was compressed under some chipboard.


funny this should come up, I was pondering this just last night.

Our loft is pretty much boarded out but I'd like to increase the insulation
up there. Don't want to take up the boarding really - and we use it for a
fair bit of storage...storage of some stuff that I'd prefer not to have in
the loft suffering extremes of temp :-(

Hence I was pondering insulating the roof somehow.

Not looking to spend a fortune on this, but what are the options for
making the roof space a bit cooler in the summer and a bit warmer in the
winter? I'm not looking to turn this into a usable room - just make it a
little more stable in temp. Currently roof is just slate - no felt or
anything just bare slates so we get a fair amount of dirt/dust in there
as well. Cutting down on that would be a bonus.

Of course, if it was a bit warmer up there I could start by grand plan
of the uber trainset in the loft (ha, as if that's ever going to happen!)

Anyone else done this and not had the roof rot away etc?
