Thanks, Andy. Since I'll almost certainly be going to glass fibre, does
the same apply?

I suppose I should have said bitumen rather than asphalt, but I dunno
whether resin would stick to it any better, if the chaps says new
decking is required, I'd tend to accept that.

When I EDPM'ed my roof the deck was soggy weetabix anyway, so got replaced.

As I said the spec on mine was decent marine ply, and I'd guess that was
what used. There's no signs of sagging. But of course fixing fresh ply to
that ain't going to cost a fortune.
