The unique shape of a mansard roof all but guarantees that you will pay more for labor and installation costs during your roofing project. Here’s what you need to know if you are replacing your mansard roof:
Some roofing materials like asphalt shingles are not suitable for mansard roofs because they will fall off the steep sides of the roof.
Heavy materials like concrete or clay tiles also cannot be installed on a mansard roof due to the steep pitch of the mansard roof design.
Lightweight metals (like aluminum) that interlock, composite shingles, cedar and other types of wood shake are all suitable for a mansard roof. The costs of these materials are:
It’s typical for labor to account for 60% of your total roofing project cost. However, if your home has a mansard-style roof, you’ll likely pay even more. That’s because the bottom slope of a mansard roof is very steep and difficult to access during a roof installation. Your roofer will have to take more time and safety precautions to complete the project, increasing labor costs.
If you are getting a new roof installed on your mansard roof, your roofers will need to remove and dispose of your old shingles. Most roofing materials can be recycled, so talk to your contractor and local recycling center to discuss what facilities exist in your area.
The majority of roofing companies will dispose of your old roof materials for you (for an extra fee), but if you do need to dispose of the old roof yourself, it typically costs $30 to $50 to dispose of a truckload of old roofing shingles at your local solid waste management center.
Due to its box-like shape, a mansard roof covers more square footage than a common gable roof. This means that you’ll pay more for roofing materials than someone with a smaller roof.
Dormers are a common feature on mansard roofs as well. If your mansard roof has dormers, you’ll likely pay more labor costs because your roofer has to take more time to install roofer around these features.
Other roof features like chimneys, skylight windows or multiple tiers of a mansard roof will lead to higher installation costs.
Perhaps most importantly, the nearly vertical side of the bottom half of a mansard roof means that your roofer will need to take extensive safety precautions during your new roof installation.
Your contractors cannot stand on the side of your mansard roof like they can stand on roofs with a lower slope, so it will take longer for your roofers to complete the installation. Talk with a local roofing expert before you start your roofing project so you know what to expect.

Mansard roofs offer a very specific look that dates back to the 16th century. However, despite being a long-standing, traditional style that can create a spacious living area, mansard roofs can also be difficult to maintain. Here’s what you should know:
The unique shape of a mansard roof lends to durability issues under harsh weather conditions, especially in colder climates.
The upper slope of a mansard-style roof is almost flat, so snow can pile up, potentially causing roofing shingles or tiles to fall off the side. Heavy rainfall and hail can also cause roofing materials to detach from the roof.
Mansard roofs are also vulnerable to ice dams. Warm air from the lower levels of the home rise up into the peak and sides of the mansard roof (the steep sides of the mansard roof also serve as the interior walls of the upper level). This uneven air flow leads to unwanted condensation on the interior and ice dams on the exterior of the roof.3
The lifespan of your mansard roof will depend primarily on the type of shingles you have. Wood shake and aluminum (metal) roofing are two suitable materials for mansard roofs. Wood shake and cedar roofs tend to last between 35 and 40 years. Metal roofing lasts 40 to 75 years.
Synthetic shingles are also a good option for mansard roofs since they will not fall off the steep side of a mansard roof the way asphalt shingles will. Synthetic shingles last 30 to 50 years.
There are three types of mansard roofs:
A mansard roof is very similar to a gambrel roof (also known as a curb roof). The structure of gambrel and mansard roofs are nearly identical, a gambrel roof just has less extreme slopes.
On gambrel roofs, the top portion of the roof is slightly steeper and the bottom section of the roof is slightly less steep than on a mansard roof. This creates more of a transition between the upper and lower roofing sections.4
Mansard roofs that are installed or insulated poorly can cause your home to be less energy-efficient, causing you to use more electricity. To maintain the greatest energy efficiency, you should insulate the wall behind the mansard box (the shape the mansard roof creates by encapsulating the walls of the upper level of your home).
Have an expert check that your roof has proper ventilation and insulation to maintain the energy efficiency of your home. Installing a metal roof can also lock in heat air in the winter and cool air in the summer, reducing your energy consumption.

A new roof isn’t cheap. Luckily, you don’t have to pay for the entire cost of your roofing project upfront. You can finance a roofing installation on your mansard roof with home equity loans or home improvement loans. Depending on the circumstance, your home insurance or home warranty may cover the cost of your new roof installation.
Talk with your roofing contractor about your financing options. Most roofing companies have connections with third-party lenders and banks to get you the best deal on your roofing financing.
The national average cost of a professional roof cleaning is $400. However, if you have a mansard roof, you will almost certainly pay more. The large surface area, as well as the steep sides of a mansard roof, means that your roof cleaner will have to take more time and precautions to complete the job.

Although mansard roofs have their downsides, if your home has a mansard roof, you should consider yourself lucky. Mansard roofs have a unique and classic appearance, despite being more difficult for roofers to work on.
Unfortunately, you will likely pay more for roofing repairs and installations on a mansard roof than other roofing types. However, it is still worth it to replace your roof when necessary. A new roof will increase the value and sustainability of your house, so don’t be hesitant to complete roofing work when necessary.
Mansard roofs provide extra living space in the upper levels of your home. This french style roof has been in use for centuries and is valued for its unique, classic appearance. Replacing your mansard roof can be a great investment, as almost all roof replacements can increase the value of your home.
In short, mansard roofs are not ideal for solar panels. The extreme angles of the roof make it difficult for the panels to receive consistent amounts of sunlight as the seasons change, limiting how much electricity your solar system can generate. If you do install solar panels on your mansard roof, we recommend mounting them at an angle on the top of your home. We do not recommend installing solar panels on the vertical side of a mansard roof. The extreme pitch makes it nearly impossible to install solar properly.
Unfortunately, mansard roofs have poor weather resistance, are difficult to install and costly to maintain. The extreme steepness of the roof makes it difficult for roofers to perform repairs, driving up costs.
