What Is a Hip Roof?

A hip roof slopes down toward the walls on every side and has no vertical gable end. A hip is the external line where two sloping roof planes meet. On a rectangular building, a simple hip roof commonly has two trapezoidal slopes and two triangular hip ends meeting at a ridge. On a square building, four triangular slopes may meet at one point, creating a pyramid or pavilion hip roof.

The eaves can form a level line around the building, allowing gutters and overhangs on all sides. Dormers are optional features, not a defining part of a hip roof.

Where Hip Roofs Are Used

Hip roofs appear on many houses, cottages, bungalows, and buildings influenced by French and American Foursquare architecture. They are also used where designers want eaves on all sides or prefer a roof without exposed gable ends. Historical use varies by region and style; “hip,” “pyramid,” and “pavilion” should not be treated as interchangeable names for every roof.

How Hip Roofs Are Built

A hip roof may use engineered trusses or a site-built rafter system with common, hip, and jack rafters. The layout depends on the building footprint, spans, roof slope, loads, and the location of ridges and intersections.

Framing, bracing, sheathing, roof-to-wall connections, underlayment, flashing, ventilation, and the roof covering must follow the engineered design, local code, and product instructions. This is not a safe do-it-yourself framing sequence; a qualified designer and contractor should specify and build the system.

Asphalt shingles, metal, tile, slate, and other compatible coverings can be installed on a hip roof when the slope, deck, and assembly meet the product requirements.

How Long Does a Hip Roof Last?

A hip roof does not have one life expectancy. “Hip” describes the geometry, while service life depends mainly on the roof covering and complete assembly, as well as climate, installation quality, ventilation, flashing, and maintenance.

Compare evidence and warranty terms for the exact covering. A generic claim that every hip roof lasts 50 years—or that any steel shingle automatically extends its life—does not account for the rest of the system.

Advantages

• Wind performance: A properly designed hip roof can reduce some wind pressures because it has no vertical gable ends. An Insurance Institute for Business & Home Safety investigation notes that previous studies generally found hip roofs more wind-resistant than gable roofs and observed more underlayment and decking damage on gable roofs. Roof-cover damage varied less by shape, so sheathing, connections, edges, ridges, and fastening still matter.
• Eaves on every side: Overhangs can shade walls and openings and help keep rain away from the siding. Their energy benefit depends on orientation, depth, latitude, window geometry, insulation, and air sealing.
• Drainage: Sloping planes direct rain toward the eaves on all sides. Snow and ice behavior depends on the slope, covering, temperature, insulation, ventilation, and local snow-load design; the shape does not make snow melt.
• Appearance: The roof creates a balanced profile on many building footprints. Whether that affects resale value depends on the property and market.

Drawbacks

• More framing and cuts: A hip roof usually requires more members and layout work than a comparable simple gable roof, which can increase material and labor costs.
• Detailing: Hip ridges require careful underlayment and cap or flashing details. Intersecting cross-hipped roofs may also create valleys. A simple hip roof does not automatically contain valleys or leak more than every gable roof.
• Attic volume: Slopes on all sides can reduce usable attic volume compared with some gable designs. A dormer may add headroom and light, but usable living space depends on framing, floor structure, egress, insulation, and local code.

Variations of Hip Roofs

A bonnet roof is a related four-sided form with a second, shallower lower slope that often extends over a porch.

Simple hip roof: On a rectangular plan, two trapezoidal slopes and two triangular hip ends meet at a ridge.

Half-hip or clipped-gable roof: A small hip replaces the upper portion of a gable end.

Dutch gable roof: A gable sits above a hipped lower roof, combining features of both forms.

Cross-hipped roof: Two or more hipped sections intersect, often creating valleys that need additional drainage and flashing details.

Pyramid or pavilion hip roof: Four triangular sides meet at one point, usually over a square plan.

Mansard roof: A related hipped form with two slopes on each side: a steep lower slope and a shallower upper slope. Read more about mansard roofs.

What Does a Hip Roof Cost?

There is no reliable national price for “a hip roof” without a project scope. Costs depend on location, roof area, slope, complexity, framing method, covering, access, permits, structural changes, and whether the work is new construction, replacement, or conversion.

Ask contractors to separate framing, sheathing, underlayment, flashing, covering, ventilation, tear-off, disposal, permits, and repairs in their estimates. Comparing itemized local bids is more useful than applying an undated per-square-foot figure to a specific house.
