Detail of a rooftop with skylights and snowThe mansard roof is an old French design, which is why they are sometimes referred to as “French roofs” in America. Created by the architect Francois Mansart, a mansard roof consists of four low-angled pitch sides that suddenly shoot up to a high-angled pitch, and then level out with a flat top. These are being seen in more and more modern homes.



The design is meant to add a good deal of attic space to the home, because of it’s high pitched sides and flat top. This is a very economical use of the space, similarly to flat roofs, but it eliminates some of the issues of water damage that such flat roofs face. Also, the flat top is usually made into a great patio or garden.

Elegant look

The mansard roof has quite a unique aesthetic, one that definitely differentiates a home. The high-angled pitch sections of the roof are meant to contain dormer windows, which are classy. The different angles of a mansard roof give the eye a lot to look at, and give an interesting appearance.


Typically, mansard roofs are incredibly long lasting. The different angles on the roof are effective in dealing with most water runoff, and they are usually made with a good deal of support to make them very durable. While they cost a bit more, they make avery good bang for your buck!



Because of the high-angled pitch portions of the roof, snowfall will usually be stacked onto the low-angled pitch sections. This can put a tremendous amount of weight on those parts of the roof, and lead to big damages if they are not supported correctly. Best not to use mansard roofs in snowier regions.

Flat part

The flat part of the roof can be very practical, and have lots of great uses that make it an exceptional addition of your home. However, it falls victim to many of the problems that a totally flat roof face. The standing water on the top of the home will have to be watched to make sure no lasting water damage is done. And, like a flat roof, it will require rubber sealing.

Complex construction

The various angles and different sections of a mansard roof make it more challenging to construct than other types of roofing. It’s not necessarily hard to do, but will take more time to measure and align everything correctly. If these alignments are off, it could lead to further home damage. This means it will also cost a bit more in labor for construction.
