That wasn't so bad - the damage was concentrated on one of the transepts (the short 'arms' of the cross-shaped floor plan) and took out the roof but not the walls. The damage was repaired in four years at a cost of only a few million pounds. This is much worse.

Also, York Minster (like, I suspect, Notre Dame) has world-class stonemasons and glaziers with expertise in medieval building methods, which certainly helps with the restoration.
