Paris zinc roofers seek Unesco heritage status

Context

The zinc covering the roofs of central Paris has given the French capital's skyline its distinctive grey hue for almost two centuries. The French culture ministry has chosen the zinc roofers as the country's entry for the UNESCO list of Intangible Cultural Heritage.

About

  • The rooftops of Paris are made using zinc and are built in the Mansard roof style.
    • These zinc rooftops were largely installed across Paris during the city’s massive redo during the 1800s under city planner Baron Haussmann. He chose zinc as it was cheap, light, weather repellant, and easy to install.
  • Paris has 128,000 roofs covering a surface area of 32 million square metres, of which 21.4mn are of the traditional zinc-covered variety.
  • Heating Problem: The zinc the covers almost 80% of Parisian roofs has come under criticism for its role in overheating buildings.
    • Darker roofs absorb more solar energy, leading to increased indoor temperatures.
    • The heat retention of zinc roofs contributes to the urban heat island effect
