A layer of felt on the upper roof lifted off, allowing water to pour into the premises.
Over 50 buckets have had to be used to collect water pouring in to the St Brigid's boxing club in Kildare Town.
Speaking to Kfm, club founder Paddy Phelan said it has endured a "massive amount of water damage" following the recent storm.
A layer of felt on the upper roof lifted off, allowing water to pour into the premises.
"We are in serious trouble," he said.
"We won't know what damage is done to the ring until the plastic is lifted off."
Paddy said the punching bags are also soaked, which can result in "rot" from the inside out.
Some training is still going ahead tonight in cordoned off areas.
Locals are advised to keep an eye on the club's social media pages for an update.
