The Health and Safety Executive has been called in after a 61-year-old fell 16-feet to his death.
Martyn Richardson was working on a barn roof at Hazels Farm, on Hollins Lane, in Kingsley, when it broke away and caused him to fall onto a concrete surface.
The Midlands Air Ambulance, two land ambulances, a paramedic officer and a BASICS doctor were sent to the scene.
But paramedics were unable to save his life and he was pronounced dead at the scene.
Now an inquest has been opened into Martyn’s death at Stoke’s civic centre.
North Staffordshire assistant coroner Sarah Murphy said: “He was working on a barn roof when it broke away causing him to fall five-metres and land on a concrete surface.
“He suffered a significant head injury and was pronounced dead at the scene. There is reason to suspect the death was unnatural and an inquest will be necessary. The family will be given a progress update in six weeks time.”
A cause of death was given as a traumatic head injury.
West Midlands Ambulance Service was called to the scene at 2.42pm on May 15.
A spokesman said: “Crews found a man in a critical condition and despite their best efforts nothing could be done to save him and he was confirmed dead at the scene.”
