Watertown isn't on the hook for all the roof repair costs to the new arena building.
In March of last year, sliding snow and ice damaged other equipment.
The city believed it to be a design flaw and went back to the Rochester engineering firm it hired.
The firm, Stantec, will pay $100,000 of the $134,000 repair bill.
In all, renovating the arena cost the city $11 million - more than half a million dollars above the original estimates.
