Recent rain has shown my flat roof is leaking. It's part of a
conversion built about 30 years ago. Very nicely built - the correct
lie etc and marine ply decking, and lead flashing. Think it is three
layer. Size approx 5x5 metres.

Any of the modern alternatives better? Membrane or fibreglass? And a
rough idea of relative costs would be nice too.

Access is easy, but it's never walked on etc except for any
maintenance.

How about old fashioned lead ?

Care to guess what that would cost? And likely to reinforce the roof which
wasn't designed for it?

Zinc would be cheaper. But noisy in the rain.
