Is A Mansard Roof In Wisconsin A Good Idea? (Pros And Cons)  

There are several different types of roofs based on their design. As a homeowner living in the Midwest, you know that hip and gable roofs dominate the skyline. While these are fairly common, if you want to stand out there is another popular roofing design: the mansard roof. 

With its distinctive double-slope design and European flair, mansard roofs can transform an ordinary house into an architectural standout. But before you get carried away with their elegant appearance, it’s important to know whether this French-inspired design can handle Wisconsin’s harsh winters and varied climate. Let’s explore if a mansard roof is a practical choice for your Wisconsin home.

What Is a Mansard Roof?

A mansard roof, also known as a French roof, is a four-sided design with two slopes on each side. The lower slope is significantly steeper than the upper slope, often with dormer windows to maximize attic space. 

For homeowners with an interest in history, this style originated in France in the 17th century, and it became popular in the U.S. during the Second Empire architectural movement in the 19th century.

Despite being one of the oldest styles, mansard roofs are still in high demand. These roofs are often chosen for their elegant aesthetics and practical use of space. However, they also come with specific challenges, especially in climates like Wisconsin’s, which experiences heavy snowfall, freezing temperatures, and occasional severe storms. 

Pros of Mansard Roofs: Is It Worth It? 

Without wasting much time, let us move straight into the facts. If you are planning to install a new roof, a mansard roof can be a great option, and it’s not just because of its aesthetic appeal. Here are some advantages of mansard roofs: 

Increased Living or Storage Space

One of the biggest advantages of a mansard roof is the extra space it provides. Unlike traditional gable or hip roofs, which have sloped attic areas that limit headroom, a mansard roof allows for a full upper floor.

This is because, unlike most pitched roofs that have a triangular top, a mansard roof has a rectangular top, i.e., it extends vertically, allowing more room. This makes it an excellent choice for homeowners looking to add more living space or create an additional storage area.

Aesthetic Appeal & Property Value

If we have to describe a mansard roof in one word, it would be vintage. Mansard roofs are visually striking and look classic, often adding a sophisticated, historic charm to a home. Their unique appearance can increase curb appeal and property value, making them a desirable feature for buyers who appreciate distinctive architecture.

Versatility for Future Expansion

If you’re planning to expand your home in the future, a mansard roof offers remarkable flexibility. The distinctive steep lower slope creates a natural framework for expansion, making it possible to add a full extra story without major structural overhauls. This adaptability can be great for growing families or homeowners who want to keep their options open for future living space needs.

Plus, adding dormer windows to a mansard roof is notably easier compared to other roof styles. The steep angle of the lower slope creates perfect opportunities for dormers, which not only bring in natural light but can transform what might otherwise be awkward attic space. 

Cons of a Mansard Roofs

As we see, the mansard roofing system carries both aesthetic and functional benefits. But with a pleasing design comes certain problems too. 

Snow Accumulation & Ice Dams

Wisconsin winters are known for heavy snowfall and ice buildup, which can pose a challenge for mansard roofs. The nearly flat upper slope can allow snow and ice to accumulate. Since the pitch is not as steep, it increases the risk of leaks, structural stress, and ice dams. Without proper insulation and drainage, this can lead to expensive repairs.

Higher Installation and Maintenance Costs

Mansard roofs tend to be more expensive to build than traditional gable or hip roofs due to their complex design. The need for additional materials, labor, and potential custom-built dormers can drive up costs. Additionally, maintaining a mansard roof can be more difficult, as repairs and replacements often require specialized expertise.

Challenging Weather Durability

While mansard roofs are built for durability, their design can make them vulnerable to extreme weather conditions. High winds, common in some parts of Wisconsin, can put pressure on the steep slopes, potentially causing shingle damage or leaks. Proper materials and professional installation are essential to lower these risks.

Limited Roofing Material Options

Mansard roofs often require high-quality materials like slate, metal, or asphalt shingles. The steep lower slope means materials must be carefully selected for longevity and water resistance. Certain roofing materials may not be well-suited for the Wisconsin climate, leading to higher costs for appropriate selections.

How to Make a Mansard Roof Work in Wisconsin

If you love the look and functionality of a mansard roof but are concerned about Wisconsin’s weather, there are steps you can take to improve its longevity and performance:

Choose Durable, Weather-Resistant Materials

• Opt for high-quality shingles or metal roofing panels for better snow and water resistance.
• Consider installing a standing seam metal roof on the upper slope to prevent ice buildup.

Ensure Effective Drainage

• Install high-capacity gutters and downspouts to manage rain and snow runoff.
• Regularly clear debris from gutters to prevent water damage.

Schedule Regular Roof Inspections

• Annual professional inspections can find signs of minor issues before they become worse problems.
• Regular maintenance, especially before and after winter, will extend the life of your mansard roof.

Other Popular Roof Styles

If a mansard roof isn’t right for you, here are some alternatives to consider: 

Flat Roof

Flat roofs are a modern and cost-effective option often found on commercial buildings and contemporary homes. They provide usable rooftop space for gardens, patios, or solar panels. However, they require excellent drainage systems, as standing water can cause leaks. In Wisconsin, flat roofs must be built with proper insulation and waterproofing to withstand heavy snow and rain.

Gable Roof

Gable roofs are one of the most common roof types in Wisconsin. Their triangular shape allows for excellent water and snow runoff, reducing the risk of leaks. Gable roofs are simple to build and offer great ventilation, but they can be vulnerable to high winds, especially if not properly braced.

Hip Roof

A hip roof features slopes on all four sides, creating a stable and durable design. This structure makes it more resistant to strong winds and heavy snowfall, making it a great choice for Wisconsin’s harsh winter storms. Hip roofs also provide consistent eaves around the home, improving energy efficiency and water drainage. However, they can be more expensive than gable roofs due to their complex construction.
