Jackson County officials say the roof that blew off the high school gym Thursday night was supposed to withstand 150 mile-per-hour winds.
Jackson County High School principal Chuck Breidert told News 2 that was his understanding of the roof's specifications.
Thursday night's winds peeled away the roof that was installed just over a year ago. They also tore away two air ducts attached to the gym ceiling.
When the air ducts tore away, two gaping holes of at least two-by-four feet were left in the roof.
One of the air ducts crashed to the gym floor while the other got caught in the supports for one of the main basketball goals.
"Thank God there was no one at the gym," Principal Breidert told News 2.
As the top of the gym peeled away, it also dislodged the roof's HVAC unit about 20 feet, wrapping it in shredded material.
School officials believe the HVAC unit, including the ducts, is about eight or nine years old.
Principal Breidert told News 2 he been outside the gym an hour earlier unloading kids bussed from an out of town school event.
According to Jackson County Schools Director Joe Barlow, the district paid the Belfor Company $182,000 for new roof.
The national company has a Hendersonville office.
It had numerous representatives and workers at the site by Friday morning.
Those there directed comments to the company's corporate office, but Belfor has not responded.
School officials believe Belfor subcontracted the roofing work.
Barlow told News 2 insurance will take care of the damage, except for a $500 premium.
