Advantages of Mansard Roof

The main advantages of a mansard roof are:

  1. As mansard roofs have vertical slopes, they provide additional space compared to other roof types like hip or gable roofs.
  2. Mansard roofs can be used for both rural and urban areas. Mansard roofs are more popular in urban areas because they give an option to expand upwards, as there is not enough space to expand the building horizontally due to land constraints.
  3. Mansard roofs allow more light and better heat distribution within the building. 
  4. Mansard roof is an element of French architecture that gives an elegant and modern look to the building structure.
  5. Mansard roofs help save costs by eliminating the need to construct separate rooms or attic spaces. They also save heating costs by evenly distributing heat inside the building.

Disadvantages of Mansard Roof

The disadvantages of mansard roofs are:

  1. Mansard roofs add to the total square footage of the building. They come with different tax values, building permits, and restrictions based on the area. Before planning to have a mansard roof for the building, it is necessary to enquire about the permit requirements.
  2. Mansard roof construction is time and labor-intensive compared to other roof construction.
  3. Construction of mansard roof is very complex, hence requires experienced professionals to work.
  4. Mansard roof is not ideal for extreme weather conditions like heavy snow and rainfall as its slope arrangement is not ideal for drainage.
  5. These roof types demand high maintenance and repair costs, as they possess less resistance to extreme weather conditions.
