NORMAN, Oklahoma - The Norman Fire Department said damages to a burger restaurant are estimated at $1.5 million.

S&B's Burger Joint caught fire and the roof collapsed as firefighters battled the flames. The owner said he is now trying to figure out his next step.

“I've never had anything like this happen,” said owner Shannon Roper. “This was a great store and a great town and it's just kind of depressing.”

Smoke started pouring from the restaurant around 4:30 a.m. and flames were coming from the second floor before too long. The older building combined with added water weight made the roof collapse during the fire.

“About 2,000 gallons a minute coming down on the structure in the windows, it certainly makes it extremely heavy inside the structure,” said Norman Fire Deputy Chief Jim Bailey.

This location is one of seven S&B Burger Joints. 

Bailey said the fire did $1 million in damages to the building and another $500,000 to what was inside.

“We were actually just planning some festivities with the music festival that's coming and so I don't really know what the next steps are,” Roper told News 9.

Luckily no one was inside at the time of the fire and no firefighters were hurt in the roof collapse. Right now, the building is not safe for fire investigators to go inside yet. Crews will have to actually pull the walls down first.

“It's just a building and a business, I mean we can rebuild it,” Roper explained.

Bailey said this fire does not look suspicious, but fire investigators will determine the exact cause.
