Air France planes are parked on the tarmac at Charles de Gaulle-Roissy airport, outside Paris, where flights were cancelled due to the heavy snowfall.
People remained calm during the evacuation of the terminal - described as a precautionary measure taken because of around two feet of accumulated snow on the roof.
Emergency workers were deployed to clear the roof, a task expected to last until around 14.00 GMT, the source said.
A few weeks after the terminal was opened in 2004, a section of the roof of the architecturally-ambitious building designed by Frenchman Paul Andreu collapsed, killing four foreign travellers and injuring six others.
French aviation authorities had announced earlier on Friday morning the cancellation of half of all flights into and out of Charles-de-Gaulle airport until 1:00 pm (midday UK) because of freezing winter conditions.
The flight cancellation meant that some 2,000 passengers were forced to stay overnight at the airport on Thursday, Transport Minister Nathalie Kosciusko-Morizet said.
