A 37-year-old man has fallen eight metres from the roof of an Oakhurst residence and sustained multiple injuries to his chest abdomen and limbs.

It is understood that he was a friend assisting the residents with maintenance to the roof.

This is CareFlight’s fourth tasking in 24 hours following similar incidents where people have fallen off roofs in Wahroonga, Dundas Valley and Avalon yesterday.

CareFlight’s Rapid Response Helicopter was tasked at 9:30am and landed 15 minutes later in Hanna Reserve, Oakhurst, where NSW Police escorted the clinical team to the scene of the incident.

NSW Ambulance paramedics were providing initial treatment for the man and CareFlight’s specialist doctor and NSW Ambulance critical care paramedic focused on treating fractures to his arm.

The patient was taken by road ambulance to Westmead Hospital in a stable condition under ongoing observation from CareFlight’s clinical team.

CareFlight’s duty doctor said: “We have noticed a dramatic increase in the number of CareFlight missions involving roof falls. As more people are undertaking home project that put them at risk, CareFlight urges individuals to take appropriate precautions when performing maintenance around the house.”
