GRP is the ultimate. 

Loses against copper and lead. (Until it gets nicked).

...and plastic coated steel (less likely to be nicked).

Personally I'd make use of the unusually high parapet wall to hide plastic coated steel sheeting when viewed from ground level.  So long as the detail between the wall and sheets is done correctly steel would give a leak-free roof for much longer than I'd be likely to worry about it.

EPDM sheeting can often be supplied as a large single sheet, unlike felt which will have seams even if it is laid using heat to seal the joins.  The guy who did my shed roof said he'd done his own shed with a single sheet over 20 feet long.  He did say it nearly killed him getting it onto the roof. :-)

I did my own shed roof with EPDM in 2021. I think it was a 4m x 6m sheet and yes, it was a pain in the bottom. But hopefully I won't have to do it again!

(Unlike shed felt, which seemed to need replacing every 5-7 years.)

OP -I would guess that the people you invite around to quote will all have their own favourite roofing sheet material, so be prepared for different opinions !

Also down to the skill of the people undertaking the work.

How is the quote any advice 

casper_gutman

For 25% extra I'd go for the fibreglass from the two options, if I could afford it. Did you ask about the possibility of increasing the slope a bit to avoid water pooling? It might add a few quid more, but could be worth considering to avoid issues later.

As Casper says.
