High winds may have played a factor in the accident, police said. The National Weather Service in Fort Worth observed winds up to 23 mph, and Dallas/Fort Worth Airport reported gusts of 29 mph at 7 a.m. Friday.
Police responded to a 911 call at about 7:05 a.m. and attempted lifesaving measures, including an automatic electronic defibrillator and CPR.
The man, who has not been identified, was deemed to be dead by Hurst firefighters, the release said.
The man was working with a roofing contractor, said Assistant Chief Billy Keadle, Hurst police spokesman.
Apparently the victim and another employee had discussed whether the wind conditions made it unsafe to use a ladder, Keadle said.
The victim had been working on a building near the conference center when he fell, according to authorities.
The Tarrant County medical examiner's office is investigating.
