What Is a Cross Hipped Roof? Structure, Design, and Performance
Also called: cross-hipped roof, cross hip roof, crosshipped roof
Cross hipped is a roof design where two or more hipped roof sections intersect at right angles, forming an L- or T-shaped structure with hips running along the junctions.
In plain English
A cross hipped roof is a roof type featuring two or more hip roof sections that intersect at right angles, forming an L, T, or similar configuration. Each section has sloping sides that meet at hips, creating a complex, multi-faceted roof geometry.
How cross hipped works
Cross hipped refers to a complex roof structure formed by the intersection of two or more hipped roof sections at right angles, creating a configuration with multiple hips, ridges, and valleys. Each hipped section features slopes on all sides, meeting at a central ridge or at the intersection points, while the eaves run along the perimeter. The geometry of a cross hipped roof typically results in an L-shaped or T-shaped building footprint, with the roof planes intersecting to accommodate the underlying structure.
Functionally, cross hipped roofs are valued for their enhanced water drainage and snow shedding capabilities, as the multiple slopes and valleys efficiently direct runoff away from the building. The intersecting hips and ridges contribute to improved wind resistance compared to gable roofs, distributing loads more evenly across the structure. However, the complexity of the roof pitch and intersecting slopes can reduce usable attic space and increase framing requirements.
Cross hipped roofs are commonly used in residential and institutional buildings with irregular or multi-wing layouts, where architectural design calls for the integration of multiple roof sections. Their structural efficiency and weather performance make them suitable for regions with varied climate conditions, though careful attention to flashing and valley construction is essential to prevent water infiltration.
Why it matters for your roof
This term matters because it affects how a roof is designed, installed, evaluated, or maintained. It also affects how homeowners, contractors, and specifiers evaluate roof durability, cost, risk, and long-term value.
Benefits
COMPLEX ROOF GEOMETRY
Cross hipped roofs feature intersecting hip sections, creating multiple roof planes for architectural interest and structural complexity.
ENHANCED DRAINAGE PATHS
The intersecting hips and valleys of a cross hipped roof promote efficient water runoff, reducing the risk of water pooling.
IMPROVED WIND RESISTANCE
The inward-sloping hips and reduced gable ends provide better wind deflection and increased stability in high-wind conditions.
INCREASED USABLE ATTIC SPACE
The cross hipped configuration often results in larger, more functional attic or upper-level spaces compared to simple hip roofs.
Limitations
COMPLEX JUNCTIONS
Cross hipped roofs require precise framing at intersecting hips, increasing structural complexity and risk of misalignment.
DRAINAGE CHALLENGES
Multiple valleys in cross hipped designs can impede water runoff, raising the risk of localized ponding and moisture intrusion.
SNOW LOAD ACCUMULATION
Intersecting hips and valleys can trap snow, concentrating loads and increasing structural stress in cold climate regions.
LIMITED ATTIC USABILITY
The intersecting roof planes of cross hipped structures reduce usable attic space and complicate ventilation pathways.
Common problems
COMPLEX DRAINAGE PATHS
Intersecting hips in cross hipped roofs create multiple valleys, increasing the risk of water pooling and drainage failure.
WIND UPLIFT AT INTERSECTIONS
The geometry of cross hipped roofs produces turbulent wind zones at hip intersections, elevating the risk of shingle or tile uplift.
SNOW ACCUMULATION IN VALLEYS
Cross hipped roof valleys trap snow and ice, leading to excessive localized loads and potential structural stress or leaks.
DIFFERENTIAL SETTLEMENT STRESS
Irregular load distribution from intersecting hips can cause uneven structural settlement, resulting in cracking or roof deformation.
Where you'll see it
COMPLEX BUILDING FOOTPRINTS
Cross hipped roofs are ideal for buildings with L- or T-shaped layouts, providing continuous weather protection over intersecting wings.
ENHANCED WIND RESISTANCE
This roof type is suitable for regions prone to high winds, as the intersecting hips reduce uplift risk compared to gable designs.
TRADITIONAL ARCHITECTURE
Cross hipped roofs complement Colonial, Craftsman, and Tudor styles, supporting authentic architectural detailing and period-appropriate curb appeal.
IMPROVED ATTIC VENTILATION
The multiple hips and valleys of a cross hipped roof allow for strategic placement of vents, enhancing attic airflow in multi-wing homes.

Frequently Asked Questions
What is a cross hipped roof?
A cross hipped roof is a roof design where two or more hipped roof sections intersect at right angles, forming an L or T shape. This style provides added stability and effective water drainage.
How does a cross hipped roof improve drainage compared to other roof types?
A cross hipped roof improves drainage by featuring multiple sloping sides that direct water efficiently toward the eaves, reducing the risk of pooling and leaks compared to flat or gable roofs.
Why is a cross hipped roof important for certain building designs?
A cross hipped roof is important for complex building layouts because it provides enhanced stability, effective water drainage, and improved wind resistance, making it ideal for homes with multiple wings or intersecting rooflines.
How does a cross hipped roof affect a building’s resistance to wind and water infiltration?
A cross hipped roof offers good resistance to wind and water infiltration due to its sloped design, which helps shed water efficiently and reduces wind uplift compared to gable roofs, enhancing overall durability.
How do you measure the total roof area of a cross hipped roof for material estimation?
To measure a cross hipped roof, divide it into simple geometric shapes (rectangles and triangles), calculate each section’s area, and add them together to determine the total roof area for material estimation.
What factors should be considered when choosing a cross hipped roof for a residential building?
When choosing a cross hipped roof, consider structural complexity, drainage, wind resistance, attic ventilation, construction costs, and compatibility with your home's layout and local climate conditions. Proper design ensures durability and weather protection.
