Hartsfield-Jackson International Airport plans to spend up to $19 million to fix the roof of the domestic terminal and Concourse T, repairing damage from a 2013 hailstorm.

The airport is seeking Atlanta city council approval for the expenditure. The work is expected to take until the end of 2016 to complete. Airport manager Miguel Southwell said he does not expect disruptions to travelers from the work.

A severe hail storm on March 18, 2013 damaged the roof membrane, “allowing rain water to seep through and enter the buildings,” according to the airport in a document submitted to city council. Temporary repairs have fixed issues after each rainstorm,”but have only served to reduce the amount of leaks.”

The domestic terminal roof project follows other work to fix damage from the hailstorm, including repairs to a cargo building roof that sustained the worst damage, according to Southwell.
