The Advantages And Disadvantages Of A Mansard Roof

Mansard roofs are roofs that have two slopes, the first of which is extremely steep, almost vertical, and the other which is much flatter and usually cannot be seen from the ground. Mansard roofs were first developed in Renaissance France, and as such have a luxurious and empirical aesthetic that other roofs cannot rival. Understanding the advantages and disadvantages of mansard roofs can help you decide whether or not it is the right fit for your home.

Advantages of Mansard Roofs

  • Future Additions: Because the first slope on a mansard roof is so steep, it can act as a wall if you ever decide to build another floor on top of your home. This allows for greater flexibility in the long run, and makes it cheaper to have such additions done on your home. As a result, mansard roofs are ideal for young couples who are looking to raise a family, but who do not want to purchase a large home right away.
  • Added Space: Even without building an addition on top of your already existing roof, mansard roofs provide extra living space when compared to other types of roofs. Because all four sides of the roof are steeply sloped in a box shape, it is easy to convert the attic space into a loft or an extra bedroom if needed.

Disadvantages of Mansard Roofs

  • Cost: Mansard roofs cost more and take longer to install when compared to other types of roofs. The process of building a mansard roof is fairly complex, and requires more labor and materials when compared to normal gable roofs. This can be prohibitive for homeowners operating under a tight budget.
  • Weather Resistance: Mansard roofs are not ideal for areas that receive heavy amounts of rain and snowfall, because the second, flat slope on the upper portion of the roof does not allow for rapid drainage of runoff. This means that large amounts of water can end up standing on your roof, which can cause leaks and mold growth inside your home.
  • Maintenance: Mansard roofs require much more maintenance when compared to traditional gable roofs, because the flatter portion of the roof collects debris much more rapidly and as such is more susceptible to damage. Though the maintenance is not necessarily grueling or expensive, it is fairly constant, and as such can be a hassle that drives up the long term costs of your roof.
