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

Some people report that fibreglass gets brittle and cracks. Thoughts?

Are you thinking fiberglass sheet like corrugated tin? I am talking about GRP roofing material that is a competing product to EPDM. Everything will eventually crack and fail, fiberglass lasts longer before compromising failure.

GRP yeah.
