I thought I'd just look online for some galvanised corrugated metal
sheets, around the same dimensions at the old asbestos, but I find
there are many products out there, including corrugated bitumen sheets.

Can anyone offer some advice on a good option here.

The modern equivalent of the corrugated galvanised metal, is a squared
box section, galvanised and painted in various colours. It comes in two
thicknesses, get the thicker one - less chance of it denting. Also get
the special self sealing bolts/screws for it.

You can get plain or ready insulated underside.

A very easy DIY job, with probably no need to cut the sheets. If you do
need to, the maker suggests cutting with a scissor like implement, which
will seal the cut edge with galv..

I did both my garage and workshop roofs with it, 10 years ago - no
complaints here.
I agree, excellent stuff and quick to fit. I did the roof and walls of a
blockwork shed last year, put 50mm celotex "seconds" under the wall
panels and between the rafters, then plasterboard'ed. It's now a very
snug shed! A couple of years before I replaced part of the asbestos wall
panels on a much larger shed and hope to finish it this year, but the
timber battens are rotten so it's a larger job.
