Station Commander Ian Smith, who was at the scene said: “This was an intense fire located in the roof of the building and fire crews worked hard in challenging conditions.
“The fire was behind a number of voids which meant access was difficult and led to this being a very protracted incident. The whole of the roof was damaged by the blaze.”
