Replacing a ?tin? roof, any pointers?

Unless you are going to do something like putting insulation on the walls (I imagine you are not) and replacing that sliding door (with a wall and a decent door) then you won?t be wanting to heat the space, and without that there is little point in insulating the roof.
I would have thought a reflective (white?) outer layer with 40 or 50mm insulation, as suggested by Down and beyond, would be about right.

Wrong wrong wrong wrong wrong.

Minimum 75 mm close cell insulated roof cladding panels (or 100mm if you can get them) with some trickle vents in a vented rigde will make a world of difference. You would be shocked how much.
Insulate the floor if you can or at the least run some pallets out on the floor and deck over them so that you have a cold well. Hang a heavy curtain over the door and stick a 100w tube heater in there as background heat and you'd be amazed.
I have a barn set up like this but worse, with hit and miss open boarding on the leeward side and I can sleep in there all year round in a summer sleeping bag.

How do we post photos up on here? I'll put up some examples.

Where do you live? Go round to any structural steel or cladding contractors and start buying up all the offcut or damaged Kingspan panels you can find. Agri contractors putting up farm sheds. Offer to empty their waste skips. You'll soon have enough. You'll also find all the flashings, foam tape and half used tubes of sealant you could ever need. They are literally giving it away.

Personally I'm fed up with second-hand stuff, and would rather buy brand-new panels and do it right. We're always in this situation trying to save money pointlessly and we can afford it. And I agree, it would make a lot of difference if done properly. My landlord put a new slate roof on our building last year - I live on the top floor, so this room and my bedroom have a sloping roof with no airspace above, unlike my living-room, which has a loft above. Until last winter it's always been pretty cold in my bedroom and in here, but as they took all the slates off they were able to fit insulation panels before they put new ones on. This winter I haven't even put my thick quilt on and hardly have the heating on - I'm sat in a t-shirt now, and I can tell how much difference it would make in there.

The problem. it's about 6m X 5m in plan with a central spine about 1.5m higher. Don't discuss the timbers! A-frame at each end and one (almost) in the middle with longitudinal beams across the span. Incidentally, it's a lot tidier and cleaner since these photos were taken :)

Worth bearing in mind that Castleton is in a conservation area, so you may need planning permission to re-clad the roof.
https://www.peakdistrict.gov.uk/looking-after/living-and-working/your-community/conservation-areas

It would certainly be worth investigating this before buying any materials as planning officers can be hard work, particularly if you get off to a bad start...

The best approach is probably to speak to the conservation officer who covers the area and get their view on what sort of thing might be acceptable. Technically, they will want to charge you for a pre-app consultation for this, but you might find that they are just pleased you want to talk to them and have an off-record discussion for free. Once you know the sort of thing they will accept, choose your preferred product and provide a sample with the planning app and hopefully they will accept it.

I doubt that they will be interested in the construction details (unless it's listed), it will be the appearance that they care about, but you might still be able to blag anything as an improvement  :LOL:

Now come on, if you think I made a mistake tell me straight.
I might be sad for a while, but I'll get over it!
