A hip roof is a type of roof that has four sides, with two slopes on each side meeting at the ridge.
The hip roof's unique design provides excellent weather protection and structural support. The roof's four sides can be made of various materials, including asphalt shingles, metal, and clay tiles.
A hip roof's shape is formed by the intersection of two slopes, known as hip ridges. These ridges are typically made of wood or metal and are designed to support the weight of the roof.
Hip roofs are often used in areas with high winds or heavy snowfall due to their ability to withstand extreme weather conditions.
Roof Design
A hip roof's design is heavily influenced by its slopes, which create a seamless look with no flat ends or gables. These smooth angles meeting at one spot require careful planning and precise measurements during construction.
In regions with heavy snowfall, a steeper pitch is often recommended to allow snow to slide off easily. This is crucial for preventing water pooling and damage over time.
A well-designed hip roof should provide reliable protection against the elements, including rain, wind, and snow. Proper ventilation helps regulate the temperature in the attic, preventing moisture buildup and potential damage to the roof structure.
Simple Design
A simple hip roof design is a great choice for areas prone to strong winds, like hurricanes or heavy storms. It offers excellent protection against these elements.
The simple hip roof design consists of four sloping sides that meet at a ridge in the middle. This creates a symmetrical appearance.
Each side of a hip roof descends from the peak, creating smooth angles that meet at one spot. This seamless look requires careful planning and precise measurements during construction.
A hip roof is like an umbrella without any bends – it's a simple yet effective design that protects against Mother Nature's elements.
Pyramid
Pyramid hip roofs offer excellent protection against strong winds and are commonly used in areas prone to hurricanes or heavy storms.
The pyramid hip roof form creates a symmetrical appearance and is an ideal choice for smaller buildings like bungalows or gazebos.
Its symmetry also gives it great stability against strong winds, making it a popular choice for homes in areas with harsh weather conditions.
The steep slopes of a pyramid hip roof limit usable attic space, but the benefits of its design make it a worthwhile trade-off for many homeowners.

Roof Types
A hip roof is a type of roof that's commonly found on homes and buildings. It's characterized by its dual slopes on either side of a central ridge.
One of the most common types of hip roofs is the gable hip roof, which features two gable ends that meet at a central ridge. This design is popular due to its simplicity and ease of construction.
The pitch of a hip roof can vary depending on the design and location of the building. A steeper pitch is often used in areas with heavy snowfall to ensure the roof can handle the weight.
Gable
The gable roof is a classic choice for many homes, and it's easy to see why. It's a simple and straightforward design that can be found in many different styles of architecture.
One variation of the gable roof is the gablet roof, also known as the Dutch gable roof. This type of roof has a hip with a small gable above it, which simplifies the construction process.
The gablet roof has some advantages over traditional gable roofs. It doesn't require girder trusses, making it a more cost-effective option for builders.
This design also allows for level walls and consistent eaves, which can be a plus for homeowners who value a sense of symmetry in their home's exterior.
Comparing Gable and Other Roof Styles
Gable roofs are less expensive to build compared to hip roofs, mainly due to their simpler design and fewer materials required.
A gable roof's triangular shape, with two slopes meeting at a ridge in the middle, is a distinctive feature that sets it apart from other roof styles.
Hip roofs, on the other hand, have slopes on all sides, meeting at the top to form a horizontal ridge, and are more expensive to build.
Each roof style has its own advantages and disadvantages, and understanding these differences is crucial when deciding which type to choose.
Gable roofs don't offer the same wind resistance as hip roofs, but their straightforward design makes them cost-effective.
The main difference between a gable and hip roof is the presence of gable ends, with gable roofs having two and hip roofs having none.
Roof Components
A hip roof is made up of several key components, each playing a crucial role in its overall structure and functionality. The most prominent feature of a hip roof is its four sloping sides, which meet at a ridge in the middle.
The four sides of a hip roof are typically covered with roofing materials such as shingles or tiles, which are designed to withstand various weather conditions. These materials are usually installed in a specific pattern to ensure proper water runoff and prevent leaks.
The ridge of a hip roof is the highest point where the four sides meet, and it's often reinforced with additional structural support to ensure the roof's stability and longevity.
Plan View
Looking at a roof in plan view can be a great way to visualize its layout. You can see the hip-rafter run as the hypotenuse of a 90° triangle with equal sides.
A Speed Square can be used to lay out both sides of the hip rafter on the plate, making it easier to establish the correct measurements. This involves measuring from point A where the layout line meets the inside edge of the top plate to the layout of the nearest king-common rafter.
The run of the hip rafter is calculated using the measurement from point A to the nearest king-common rafter. This calculation is then used to determine the length of the hip rafter.
In a simple hip roof design, the slopes are usually equal in length, creating a symmetrical appearance. This design offers excellent protection against strong winds and is commonly used in areas prone to hurricanes or heavy storms.
The magic in a hip roof lies in its slopes, which create no flat ends or gables – only smooth angles meeting at one spot.
Design Considerations
A hip roof's design requires careful planning and precise measurements during construction.
The slope of a hip roof should be calculated to ensure proper drainage and prevent water pooling, which can lead to leaks and damage over time.
Regions with heavy snowfall often require a steeper pitch to allow snow to slide off easily. Conversely, areas prone to high winds may need additional reinforcements to ensure the roof remains secure.
Proper ventilation is essential for a hip roof design, helping to regulate the temperature in the attic and prevent moisture buildup.
A well-designed hip roof should provide reliable protection against the elements, including rain, wind, and snow.
The magic in a hip roof lies in its slopes, which create no flat ends or gables – only smooth angles meeting at one spot.
Hip roofs make up for their gentler slopes with better stability, making them well-suited for areas with high winds and heavy snow.
A hip roof's main benefit is its self-bracing design, with all four sides having an inward slope that helps make it durable and structurally stable.
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 space in the attic, which can be converted into living areas.
The lower roof angle of a mansard roof is typically much steeper than the upper one, creating a distinctive look that's both functional and visually appealing.
Tented
Tented roofs are a type of polygonal hipped roof with steeply pitched slopes.
They rise to a peak or intersection, creating a unique and visually interesting design.
A key characteristic of tented roofs is their steeply pitched slopes, which can be a challenge to navigate during construction.
However, the end result is often worth it, as tented roofs can add a touch of elegance and sophistication to a building's design.
In terms of functionality, tented roofs can also provide additional space and storage, particularly if the tented area is designed with a clear roof or skylights.
Common-Rafter Pitch
If you're framing a roof, you'll want to get the common-rafter pitch just right. This is the angle at which the common rafters meet the ridge beam. To keep things simple, you can use the layout from the sidewalls and create a mirror image on the end walls.
The distance from the short point of the hip rafter's seat cut to the jack-rafter layout mark is also the run of the jack rafter to the short point of the bevel cut. This is a key measurement to get right.
To calculate the lengths of the jack rafters, use the common-rafter multiplier. This will give you the exact lengths you need for each rafter. The plumb cut is then made with your saw set at a 45° bevel, creating the jack rafter's bevel cut.
Here are the key measurements to keep in mind:
- Distance from the short point of the hip rafter's seat cut to the jack-rafter layout mark
- Run of the jack rafter to the short point of the bevel cut
- Common-rafter multiplier (for calculating jack rafter lengths)
Figure Length
To get the length of your rafters, you need to find the run first. For common rafters, lay out the jack rafters on the top plate and measure from point A to the jack-rafter layout mark. This measurement is equal to the run of the jack rafter.
For hip rafters, mark the hip-rafter layout on the top plate and measure back to the nearest king common. Multiply this distance by the square root of 2 (1.414) to get the hip-rafter run.
Once you have the run, you can use a multiplier to get the rafter length. For common rafters, multiply the jack-rafter run by the common-rafter multiplier. For hip rafters, multiply the hip-rafter run by the hip-rafter multiplier.
Here's a quick reference guide to help you remember the multipliers:
This will help you get the length of your rafters quickly and accurately.
Selecting Materials
Choosing the right roofing materials is crucial for a hip roof. Asphalt shingles are a popular and affordable option, but they may not last as long in extreme climates.
Asphalt shingles are relatively easy to install, making them a great choice for DIY enthusiasts. However, their lifespan can be shorter than that of metal or tile roofing.
The size of your hip roof will influence the type and quantity of materials needed. A larger roof will require more materials, while a smaller roof will require less.
Remember, the right materials will make all the difference in the durability and appearance of your hip roof.
