Rain on Mayo flat roofs
Castlebar is the wettest of the Mayo towns here at 1,458 mm a year, and Ballina the driest at 1,222 mm. Castlebar gets 462 mm between December and February, when a GRP roof can't be laid. Its driest month between April and September is May, with about 87 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.
