Rain on Cork flat roofs
Bantry is the wettest of the Cork towns here at 1,611 mm a year, and Mallow the driest at 1,072 mm. Cork city gets 328 mm between December and February, when a GRP roof can't be laid. Its driest month between April and September is May, with about 72 mm: the best time to have the roof open.
This much rain makes the fall and the outlets matter more than the membrane. Ask what fall the new roof will have: see falls and ponding. Met Éireann's 1991–2020 averages, within 3 km of each town.
