None fitted here. Building control were stressy about maintaining a 50mm gap between the insulation and the membrane but ignored the lack of soffit vents.

Not even ridge vents?

No. Mind, these are Marley rolled concrete tiles so hardly an airtight fit. They did fit plastic eyelashes to discourage birds and insects at the eaves.

The standard cast iron are of a very poor design, unlike the SD1 which are pretty good. But on a P5, I'd be worried about increased noise.
I've a feeling many of these sort of progs get paid to feature a particular product or service.

In those days - and later - most cars had cast iron exhaust manifolds. Far cheaper to make than mild steel, which would have to be fabricated.

Thought it was more as a secondary waterproof layer for when a tile/slate slips/breaks or the wind is in the "wrong" direction and blows water up and under the tiles/slates.
Also keeps the atmospheric fall out out of the loft.

Sarking has no single meaning beyond being something under the tiles or slates.
Mostly in the UK its there to stop tiles blowing off.
It can do other stuff as well, though.

So is this a 'warm' roof with the insulation up at the tile level? And they didnt insist on venting it?
Ther is a certain login in that internal moisture simply won't get past all that foil and tape, compared to e.g. rockwool. So the need for massive vents to prevent rafter rot is not there

Dry blowing snow for example. We once had 2" of snow in an unfelted (Edwardian built) loft.

Argh, I'd forgotten about dry powder snow! Bastard stuff follows the air flow and is capable of doing so through door jams, ie around 2 x
90 degree bends. We've had the roofs stripped, breathable membrane laid and reslated powder snow is no longer a problem in the lofts, even with the "Beast from the East". Same can't be said for a couple of the older doors and windows though.- Vote on answer

A house is being renovated/ modified down the road from us. The work has being going on some time, we?ve been away since end of May and it had been going on for some weeks then, they are about to tile the roof by the looks of things now. It has new looking sarking felt.

I don't think it's anything to do with cost; just that the further north and west you go, the wilder the weather.

Victorian barn and farmhouse here, mid Herts. have timber sarking. Relatively small slate (9"x18") roof may be linked. Interesting boards: about 9" wide and barely 5/8" thick. Unwarped so must have been carefully cut.

Very true. Sarking is more important than ties in a cavity brick wall. ;-)

Its not unheard of round here either. My business partner's place has timber sarking boards, and that is a fairly conventional 1930s semi in Southend.
