For a Victorian mansard roof, you'll want to choose a roof covering that's up to the task. Traditionally, slate tiles were used, but they can be quite heavy and might not be the best fit for this unique roof design.

Francois Mansart may not have invented the roof style, but he certainly made it famous. The roof design first appeared in Europe in the mid-16th century, with Pierre Lescot incorporating it into a wing of the Louvre Museum around 1550.

Mansard roofs soon made their way across the Atlantic, becoming popular for colonial-era homes in the Northeast. They were a staple in French architecture, and their popularity continued to grow.

By the mid-19th century, interest in French architecture surged, and Mansard roofs were installed on many government buildings and stately homes. You can see an example of this in the distinctive four-story Mansard roof on the Germania Life Insurance Company building on Park Avenue in New York City.
