A hip roof design is a type of roof where four sloping sides meet at the top, forming a ridge. This design is commonly used in traditional and modern architecture.
Hip roofs are often associated with a more rustic or country-style aesthetic, but they can also be found in sleek and contemporary designs. The key to pulling off a hip roof is to balance the shape with the surrounding architecture.
The advantages of a hip roof include improved structural integrity and better weather resistance. This is because the four sides of the roof provide additional support and help to distribute the weight of the roof evenly.
A well-designed hip roof can also add visual interest to a building, making it stand out from more traditional roof designs.

What Is a Hip Roof?
A hip roof is a type of roof where all four sides slope downwards to meet at a single point. This distinctive layout is visually appealing and valued for its ease and resilience.
Hip roofs are often found on structures that require strength and stability, such as church steeples and suburban houses.
Variations of Hip Roofs
Hip roofs are incredibly versatile, and their various forms can add unique character to a building. A pavilion roof, also known as a pyramid roof, is a classic example of a hip roof on a square structure.
There are several types of hip roofs to consider, including the mansard roof, which features two different sloping angles on each side. The lower angle is much steeper than the upper angle, giving the roof a distinctive look.
A tented roof has multiple steep sides that slope up to a peak, often seen in church steeples. The Dutch gable roof is a variation of the hip roof, with a small gable section on the upper portion of the roof.
Here are some of the main types of hip roofs:
- Pavilion or Pyramid Roof: A square building with a hip roof that creates a pyramid shape.
- Mansard Roof: A roof with two sloping angles on each side, with the lower angle much steeper than the upper angle.
- Tented Roof: A roof with multiple steep sides that slope up to a peak.
- Dutch Gable Roof: A hip roof with a small gable section on the upper portion of the roof.
- Half-Hip Roof: A combination of a gable and hip roof, with a small hip roof section that slopes toward the ridge.
Types You Should Know
A hip roof is a great choice for your home, but did you know there are various types to consider? Let's explore some of them.
The Pavilion or Pyramid Roof is a common hip roof on a square building, creating a pyramid shape. It's a simple yet elegant design that's perfect for modern homes.
The Mansard Roof has two sloping angles on each side of the roof, with the lower angle much steeper than the upper angle. This design adds a touch of sophistication to any building.
Tented Roofs have multiple steep sides that slope up to a peak, often seen on church steeples. They add a sense of grandeur and drama to any structure.
The Dutch Gable or Gable Roof is a hip roof with a small gable section on the upper portion of the roof. This design combines the best of both worlds, offering a unique look and extra space inside.
The Half-Hip Roof, also known as a Clipped Gable, is a harmonious blend of hip and gable roofs. It's a great option for those who want a traditional look with a modern twist.
Here are the main types of hip roofs you should know:
- Pavilion or Pyramid Roof
- Mansard Roof
- Tented Roof
- Dutch Gable or Gable Roof
- Half-Hip Roof (Clipped Gable)
- Dutch Hip Roof (Hip and Valley Roof)
Mansard
A mansard roof is a variation on a hip roof, with two different roof angles, the lower one much steeper than the upper.
This unique design allows for more living space, often used in attic conversions or additions.
The steeper lower angle of a mansard roof provides more headroom and makes it easier to walk around in.
This is especially useful in areas where space is limited, such as in urban or historical neighborhoods.
In contrast to other hip roof variations, a mansard roof's steep lower angle can be a distinctive feature of a building's design.
This can add character and visual interest to a building's exterior.

Advantages and Disadvantages
A hip roof is a great design choice, but like any other, it has its advantages and disadvantages. One of the main advantages is that it's self-bracing, requiring less diagonal bracing than a gable roof.
Hip roofs are also much more resistant to wind damage than gable roofs. This is because they have no large, flat, or slab-sided ends to catch wind, making them inherently more stable. I've seen this firsthand in areas prone to high winds, where hip roofs have withstood the test of time.
A different take: Gabled Roof Definition
However, for a hurricane region, the roof also has to be steep-sloped; at least 35 degrees from horizontal or steeper in slope is preferred. If the roof slopes are less than 35 degrees from horizontal, the roof is subject to uplift.
One of the main disadvantages of a hip roof is that there is less room inside the roof space, making access for maintenance more difficult. Hip roofs are also harder to ventilate and don't have a gable with a window for natural light.
Here are some key points to consider:
- Self-bracing, requiring less diagonal bracing
- More resistant to wind damage
- Steeper slope required for hurricane regions (at least 35 degrees from horizontal)
- Less room inside the roof space
- Harder to ventilate
Design and Construction
Designing a hip roof requires precision and patience, much like crafting an origami masterpiece. The material selection is critical to ensure durability in various weather conditions.
Hip roofs are designed to be self-bracing, with all four sides having an inward slope that makes them durable and structurally stable. This design is particularly beneficial in areas prone to high winds, heavy snow, or other severe weather.
The framing of a hip roof involves a ridge board at the top where the roof faces meet, while hip rafters follow along the line at each connection point. This support system helps distribute weight evenly, making the roof better equipped to handle varying weather conditions.
Here are the key components of a hip roof framing system:
- Ridge board: the top plate where the roof faces meet
- Hip rafters: follow along the line at each connection point
- Common rafters: connect to the ridge board at the top and the eave or fascia at the bottom
- Jack rafters: installed in the area where the roof slopes down
Tented
A tented roof is a type of polygonal hipped roof with steeply pitched slopes rising to a peak or intersection.
These roofs can be quite dramatic, making a bold statement in any architectural design.
Tented roofs are characterized by their steeply pitched slopes, which can be a challenge to construct, but the end result is well worth the effort.
Construction
A hip roof can be constructed on a wide variety of plan shapes, with each ridge central over the rectangle of the building below it. The triangular faces of the roof are called the hip ends, and they are bounded by the hips themselves.
The hips and hip rafters sit on an external corner of the building and rise to the ridge. Where the building has an internal corner, a valley makes the join between the sloping surfaces, and is underlain by a valley rafter.
Hip roofs have the advantage of giving a compact, solid appearance to a structure. The roof pitch (slope) may vary.
Here are some key aspects to consider when constructing a hip roof:
- Plan shapes: Hip roofs can be constructed on a wide variety of plan shapes, including square, rectangular, and uniquely shaped buildings.
- Ridge placement: Each ridge is central over the rectangle of the building below it.
- Hip ends: The triangular faces of the roof are called the hip ends, and they are bounded by the hips themselves.
- Valley formation: Where the building has an internal corner, a valley makes the join between the sloping surfaces, and is underlain by a valley rafter.
The construction of a hip roof requires precise measurements and skilled craftsmanship, which might translate to slightly higher labor costs.
Frequently Asked Questions
What is the difference between a gable and a hip roof?
A gable roof has two triangular slopes, while a hip roof has four slopes that all meet at the roof's peak. This key difference affects the overall design and functionality of each roof style.
