This is the shocking moment which shows black smoke ripping through the roof of a house in Welling. 

A house in Sidmouth Road was believed to have been struck by lightning at 7.40am today (June 20).

Four fire engines and around 25 firefighters were called to the scene. 

The video, taken by a passerby, shows firefighters working to put the fire out.

A fire engine is visible next to the house with blue lights on and sirens flashing.

It appears that Sidmouth Road is also covered in the smoke coming from the house fire.

The roof of the semi-detached house was partially damaged by the fire, London Fire Brigade has confirmed.

Residents escaped the building before fire crews arrived and no injuries were reported.

The fire was under control by around 9am.

A spokesperson for London Fire Brigade said: “This morning four fire engines and around 25 firefighters attended a fire on Sidmouth Road in Welling.

“The roof of a semi-detached house was partially damaged by the fire.

“Residents had left the building before crews arrived and there are no reports of any injuries.

“Crews deployed a 32m Turntable Ladder as an observation platform.

“This allowed the Incident Commander to monitor the fire in the roof from above, whilst firefighters tacked it from the inside.

“The Brigade’s 999 Control Officers took seven calls reporting the fire, the first received at 7.40am.

“Firefighters had the incident under control by 8.57am.

“Crews from Plumstead, Greenwich and Bexley attended the incident.

“It is believed the fire may have been started by lightning striking the roof.”
