EDPM vs Fibreglass for a flat roof (lemmy.sdf.org)

Hi,

Any of you folks know about EDPM vs Fibreglass roofing.

I need to make a choice for a property extension in the UK. I expect rain, a few hot days, more rain, more rain, and some ice.

The roof won't be load bearing (people won't be walking on it).

Seems like every other website has differing opinions on what's best. I guess because everyone is selling something.

Any impartial opinions on what you'd use?

Cheers

Necropost, but did you choose one in the end?
I've just had to DIY an EPDM, and honestly...It's not horrible to work with, and if done properly shouldn't have any issues.

Every builder I got a quote from recommended fibreglass over EDPM since we are going to have a roof lantern.

The builder I'm going to uses this system: https://www.tuffstuff.co.uk/

Sounds good to me. If you're getting a builder to do it, you're almost definitely better off with whatever system they're happy using.
Everyone will have their preference that they feel most comfortable with.

Honestly, I reckon it's 6 of one, half a dozen of the other. Over 25 years, it'll probably do the same job.
