The 911 call was made from the Hill School around 11:40 a.m. Monday.
According to Cathy Skitko, the Communications Director at the Hill School, two roofers who work for RL Sensenig fell through the roof of the building.
It took officials about an hour to finally free the injured worker. The severity of the injuries sustained in the fall are unclear at this time.
The other worker died as a result of the fall.
The identities of victims have not been released.
The building being worked on is the power facility for Hill School and is located on the outskirts of the campus. It is not an academic building.
The roofers were working on a part of the building that is not in use at this time.
Skitko released a statement saying "The Hill School expresses their most sincere sympathy and concern to the family of the man who died in this tragic accident."
