After about 30 years the shed roof needs re-felting - one side has slipped
due to the wind and sun.

Originally it was nailed with galvanised nails. Where it was nailed it has
now torn.

Is there a better way using glue nowadays?

There are several options... the traditional three layer felt would use
a nail prep layer (a hessian re-enforced felt) random nailed, and then
underlay and top felt layers hot bonded with tar or glued to that.

My personal preference is using torch on felt (usually a modified /
rubberised bitumen style like SBS felt). Just two layers - a 2mm
underlay, and then a 4mm mineral finish top coat. Sticks like the
proverbial to a blanket, and very quick and easy to apply so long as you
have or can borrow a decent sized blow torch.

Bitumen paint. It's cheap & works pretty well. Nailing is asking for failure.

What do you do with the bitumen paint on an old felted shed roof? Paint
over the felt? Use it to stick joins or seal nails? prime?

Do you expect to live another 30 years? ;-)

Would you expect that to last 30 years? Mine was made like that and has
needed a few repairs - apparently were the adhesion had failed.

It's glue. Stick the felt down with it.

I have not had any indication of loss of adhesion with the torch on
stuff I have used so far. So I would expect it to last toward the upper
end of what you can expect from felt in general. However none of the
jobs I have done with it are 30 years old yet, so I can't say for
certain from personal experience.

If looking for maximum life, then two layers of undercoat would probably
help.
