Mansard Roofs Pros and Cons


Mansard roofs, also known as French roofs, are a popular architectural style that originated in France during the 17th century. They are characterized by their distinct double-sloped design, with the lower slope being steeper than the upper slope. This unique roof style offers both advantages and disadvantages, which we will explore in this article.

Pros of Mansard Roofs

1. Increased Living Space: One of the main benefits of mansard roofs is that they provide additional living space in the form of an attic. The steep lower slope allows for more headroom, making it ideal for converting the attic into usable living space such as bedrooms, offices, or playrooms.

2. Versatility in Design: Mansard roofs offer great design versatility. The upper slope can be designed with various materials such as shingles, metal, or tiles, providing the opportunity to match the roof with the overall architectural style of the house. Additionally, the steep lower slope allows for the installation of dormer windows, adding aesthetic appeal and natural light to the attic.

3. Energy Efficiency: The double-sloped design of mansard roofs allows for better insulation, resulting in improved energy efficiency. The attic space created by the lower slope acts as an additional layer of insulation, keeping the house cooler in summer and warmer in winter, which can lead to energy savings and reduced utility bills.

4. Increased Property Value: Mansard roofs are often considered an attractive feature in real estate. The added living space, design versatility, and energy efficiency they offer can increase the overall value of a property, making it more appealing to potential buyers.

Cons of Mansard Roofs

1. Cost: Building a mansard roof can be more expensive compared to traditional roof styles due to its complex design and additional construction requirements. The cost of materials, labor, and maintenance may be higher, which is an important consideration for homeowners on a tight budget.

2. Maintenance Challenges: The unique design of mansard roofs can make maintenance and repairs more challenging. The steep angles and dormer windows require special attention during inspections, cleanings, and repairs. Additionally, the complex design can make it harder to find contractors with experience in working with mansard roofs, potentially leading to higher costs for maintenance and repairs.

3. Limited Weather Resistance: Mansard roofs may have a lower resistance to extreme weather conditions such as high winds and heavy snowfall. The shallow upper slope and steep lower slope can make the roof more susceptible to damage. Proper reinforcement and regular inspections are necessary to ensure the structural integrity of the roof.


Mansard roofs offer several advantages, including increased living space, design versatility, energy efficiency, and increased property value. However, they also have their drawbacks, such as higher costs, maintenance challenges, and limited weather resistance. Before deciding on a mansard roof, it is important to carefully consider these pros and cons and consult with a professional to determine if it is the right choice for your specific needs and budget.
