Scientists said it was the first such space rock ever to have been found so close to the French capital and one of only about 60 meteorites to have landed in France in the past four centuries.
It is thought the meteor struck the house a few weeks ago when the Comettes were on holiday, which explains why they did not hear it crash landing.
They were only made aware of its presence when the roof started leaking.
"We got the roof tiler round and he was astounded," said Martine Comette, 32. "He said: 'You need to be Superman to break a tile like that! It must be a meteorite.'"
