What is a Mansard Roof?

Mansard is a type of roofing that is known to have two slopes on every side of it, with the lower slope being considerably steeper than the upper. If you look at a cross-section of it, you might mistake it for a gambrel roof, but it actually differs a lot from it if you display the same profile on all sides. That’s because gambrel roofing only has two sides, and a traditional Mansard roof has four.

The History of Mansard Roofs

The Mansard roof was popularised back in the 17th century by a famous architect named Francois Mansart. During that time, this style of roofing was unheard of, so Mansart used it as his own distinctive style when making houses and buildings. He used it extensively when building chateaus and grand townhouses that caught the attention of many people. For that reason, the style was eventually named after him, even though he wasn’t technically the one who created it.

The true creator of the Mansard-style of roofing was Pierre Lescot. Back in the year 1550, Lescot used this particular style on a part of the Louvre Museum in Paris, France. While it became a bit popular for a short period of time, Mansart’s use of the style made it an exceedingly fashionable feature in many architectural masterpieces in France and the rest of Europe. Eventually, Mansart’s architectural designs spread like wildfire, and it even reached other western countries, including Canada and the United States of America. Aside from their aesthetic features, Mansard roofing systems were generally favoured by many people during that time because it’s relatively easy to repair when damaged due to their design.

Mansard Roof vs Other Roofing Styles

Mansard roofs feature a distinctive design with two slopes on every side of it. Other roof covering types like the gable-style roofs only have one slope on the front and back of the home. It also doesn’t come with a slope or overhand on the sides. In a hip-style roof, on the other hand, there’s also one consistent slope of the roof, but it exists on all four sides of the home rather than only on two like the gable. The reason Mansard roofs are compared to these two styles is that those two are much more commonly used today than the Mansard. 

Advantages of Mansard Roofs

Despite Mansard roofs being rarely used in building construction compared to its former popularity, it still has many advantages that other styles may or may not have. Some of the most notable advantages of Mansard roofs include the following:

  • Customizability – Due to the unique slope of Mansard roofs, they make home customisation a lot easier to pull off. The sloops are nearly vertical, making it easier to add additional floors to homes with Mansard roofs.
  • Extra Attic Space  – In most homes, attics take up the topmost area of the structure. However, compared to a standard gable or hip roof, the Mansard offers significantly more attic space due to its shape.
  • Better Lighting – The shape of the Mansard roof’s slopes offers many advantages in terms of space and utility. If you use dormer windows on the entire length of the bottom slope of the roof, you put more natural light inside the building, which in turn makes it seem a bit more spacious than it is.
  • Lower Heating Costs – Unlike other roofing styles, Mansard roofs allow heat to be evenly distributed throughout the top of your house. That’s because the flat top of the roof is able to direct and concentrate most of the heat on it instead of spreading it out across the wider roof. This helps reduce heating costs.
  • Aesthetic Value – The appeal of a house can be extremely subjective, but you can’t deny just how magnificent and elegant the design of a house built with a Mansard-style roof over it. It makes any house look more sophisticated, similar to the effect it had on French architecture during the Renaissance period.

Disadvantages of Mansard Roofs

Of course, along with the advantages also come with some disadvantages that even the Mansard roof has. It’s by no means a perfect roof design. Here are some of the most common and pressing disadvantages.

  • Weather Resistance – Honestly, Mansard roofs aren’t exactly the most functional. They’re actually quite unsuitable in areas with extreme weather conditions. The almost flat slopes mean that it will not cope well with heavy rainfall, which can result in leaks on the roof. When it’s snowing, the weight of the snow can be too much for the flat top to bear and could even result in the entire roof collapsing.
  • High Installation Costs – Mansard roofs are on the more expensive side of things when it comes to installation. The complexity of the design will lead to a high installation cost compared to other simpler roof designs. Since Mansard roofs aren’t as common as they were before. Not a lot of contractors are familiar with how it’s constructed and designed.


Mansard roofs proved to be quite revolutionary in terms of their design and construction back when they were first introduced. It still remains one of the most elegant-looking roof covering types still used today. But with more modern and efficient designs being used and developed, the Mansard style has become more of an iconic piece of architecture than a practical choice for construction.
