The Mansard roof is among the most popular types of roofs across the world. This particular roof consists of four sides, two of which have slopes, and have no gables.
The lower of the two slopes are very steep, practically like a vertical wall, while the upper of the two slopes consists of a low pitch that is hard to see from the ground and is simply there to permit proper flow of water off the roof.
Recognizing a Mansard Roof
When it comes to identifying a mansard roof, there are two things to be on the lookout for a double pitch and steep slopes, or sides. Sometimes, homes with steep sides accompanying a single plane roof can often be mistaken for a mansard roof. Easily so, since the mansard roof’s upper slope is not visible by someone standing on the ground looking up at the building and roof.
Further, a barn roof may also be mistaken for a mansard roof. However, the main difference between these two roofing styles is the fact that the barn roof, which is also known as a gambrel roof style, consists of two sides with steep slopes while the mansard roof, of course, has steep slopes all the way around. You could call the barn roof a curb gable roof due to only two sides of the roof having steep slopes and the mansard roof a curb hip roof because of all sides having slopes.
Throughout Germany as well as France, the gambrel roof and the mansard roof are considered on in the same – all are mansard roofs.

Today’s Use of the Mansard Roof
More often than not, the mansard roof is used on apartment buildings, Neo-eclectic homes as well as restaurants. It is recommended that the mansard roof not is used in areas with heavy snowfall, as the weight from the snow could cause an unnecessary force on the low slope section of the roof creating a strain – and eventually, a break – in the bracing of the roof.
And, if we were to be true to ourselves, most buildings that incorporate the mansard roof aren’t actually using the entire mansard roof design. In fact, many buildings – such as those in big cities like New York City – simply use the mansard roof design as a façade on the front of the building for appearances only and are simply flat surfaces rather than building the entire roof in the mansard style.
Essentially, this keeps those passing by from noticing the heating, air conditioning and ventilation equipment that is installed on the rooftop of the buildings.
