Epdm roofing sheet (St George's Park BS5)

My mum's shed had a chunk of tree come through the roof. It's got an epdm sheet roof, so I am after a bit of EPDM rubber about 2.5 m long x 80cm and some bonding g glue ..if anyone has leftovers from a project I'd be grateful. Not as grateful as for the fact she wasn't in the shed. 3 of her folding chairs got obliterated, it was quite a branch!!
