Freddie, no.
I became interested in insulation some years ago, when I discovered closed cell insulation, I saw the benefits and gutted my first house, lining the walls and ceilings with inch thick polystyrene, glued to the walls to avoid breaks in the insulation. It worked very well indeed, reducing my fuel bills way below those of the five other identical houses in our row.
The only downside, was where I had nailed the plasterboards, the nails conducted the heat through the polystyrene into the wooden joists forming a cold patch under the plaster and after a while you could see each nail head as a grey spot.
At the time, the sprayed foam had a bad press, because of the way it was/and is applied. I would not recommend sprayed foam under tiles or slates, because of that.
However, covering a roof totally with five inches of polystyrene and then laying two inches of light weight re-in forced concrete over that does an almost perfect job.
