Anyone give a rough guide as to costs - felt, membrane, glass fibre?

I have been thinkig about flat rooves. I'd go one piece EPDM. Call up a
few people and ask about a price for the job.

Quite easy to DIY, but whoever does it will have to overboard
the existing plywood decking with another layer of ply or
OSB3 because the water-based adhesive needs a clean substrate.

Must admit to wondering why the existing can't be cleaned, if in good
condition?

"You must ensure that the decking is completely dry and clear of any
surface debris before applying the ClassicBond EPDM Deck Adhesive. Of
course, installation couldnt be easier making this product ideally
suited for both amateurs and professionals alike".

Yoiu can also get a primer for the job.

But if it's been felted before, it'll have asphalt on the deck, which
"nothing" sticks to, and it's difficult to get it off completely.

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.
