The cathedral in Leon, Spain, a slightly older gothic church, was the scene of a very similar fire when a badly grounded lightning set the wooden roof on fire in May, 1966.

The damage wasn't as pronounced thanks to the stone used for the top, which was chosen for its lightness but had the added benefit of having volcanic-like properties. And especially thanks to a local mason who made the call to pull the fire brigade and sacrificed more of the wooden roofing to prevent the water weight from making the vault collapse.

I haven't found much info in English but here's a detailed account in a Spanish blog: http://cosinasdeleon.com/el-incendio-de-la-catedral-de-leon/
