It took about eight weeks to completely replace the building’s roof, which was leaking for several years, officials said.
The $650,000 repair job, sponsored by Councilwoman Karen Koslowitz, was initially scheduled to begin in November, but the renovations were delayed until all city work permits were approved, the library said.
The repairs were scheduled to take about six weeks, but lasted a little longer due to the rain, the library said.
While the building remained closed, patrons were able to use the mobile library twice a week.
The branch, at 108-19 71st Ave., provides numerous family programs and is among the five busiest in the borough, lending out about 389,000 items per year, library officials said.
On June 15, the branch will follow its regular Thursday schedule, from noon to 8 p.m., the library said.
