Apparently mostly roof damage, unclear how much damage inside.
Just thinking of ignition sources. Big buildings typically have their HVAC units on their roof. A fire needs an ignition source and where there are moving parts, belts, circuit breakers, etc there are things that can ignite when they aren't operating properly. Other common causes of roof deck fires IMO are attributed to people working on the roof (i.e. discarded cigarettes or workers using heat when laying tar on some roofs, sometimes welding or saws creating sparks, etc), but since this fire was at night that wasn't the first thing that jumped to my mind.Why would you believe the HVAC might be the root cause?

<maga voice> Oh, come on, how does it work with no sun... </maga voice>Rooftop solar arrays can also be a problem…even at night.
So, ncsulol fans.Raleigh FD said it was caused by natural gas.
