Posted By: Pile-o-StoneWhen we stripped our roof, we fitted TLX Gold multifoil insulation on top of the rafters (this is a breather membrane and mutifoil in one product, with a 75mm air gap and 25mm celotex between rafters and 100mm celotex beneath the rafters.

And presumably ventilated?
Posted By: tonyReroofing triggers part L1b of the building regulations and though never enforced the require the insulation to be upgraded as part of the works.I'm in a conservation area, so if I can't physically fit enough insulation in I can apply to not have to meet the building regs. No idea if the council would accept this or not.

Charli, are you only prepared to do insulation on the 'cold side' - in the voids where it won't have to disturb ceilings etc.? Are you going for 'best you can', or have you got an overall Plan? How about drawing it out, estimating U values (or calculating - it's easy) for each area, and looking for 'weak spots'? Don't forget to calculate (and discount for) the timber fraction (the amount of the 'insulation' that's wood).
Posted By: WillInAberdeenWe got more interest from joiners than from roofers about insulation.
For the small triangle attic area, just add lots more mineral wool on top of the ceiling, joiner does this later, or DIY. Maybe need to add ventilation slates to compensate for loss of gaps between slates. (Edit: this would often be done with vents in the soffits, but you hardly have any soffit between the windows! Do you need any work on the timber, repairs to fascias bargeboards etc? Joiner does this while scaffolding is up. Take opportunity to paint?)
