A hip roof is a roof that slopes down on all four sides to the eaves, with no vertical triangular gable walls at the ends. Where two sloping planes meet at an outside corner, they form a sloped ridge called a hip, which gives the roof its name. If you are asking what is a hip roof because it came up in a listing, an insurance form or a roofing quote, the short answer is that it is a compact, self-bracing roof shape that generally performs better in high wind than a gable roof, at the cost of more complex framing, a higher price per square foot and less attic space. Hip roofs are common on Front Range ranches, prairie-style homes and many newer two-story builds. This guide explains how a hip roof is built, the main types, the terms on a quote or report, typical costs and lifespans, maintenance, common problems, how it compares with a gable roof and what an inspector checks.

Hip Roof Defined

On a simple hip roof over a rectangular house, the two long sides slope up to a horizontal ridge, and the two short ends slope up to meet the ends of that ridge. The four sloped corner lines running from the ends of the ridge down to the corners of the house are the hips. On a square house, all four planes meet at a single peak, a form often called a pyramid hip.

FEMA’s guidance on sloped roof systems treats gable and hip shapes as the two basic forms of sloped roof, which it defines as a pitch of 3 inches of rise per 12 inches of run (3:12) or steeper. The defining difference is the ends. A gable roof leaves a tall, flat triangular wall at each end; a hip roof replaces that wall with another sloped roof plane. Our companion explainer on gable roofs covers the two-slope alternative, and the comparison table later in this guide sets the two side by side.

Because every wall sits under an eave, a hip roof wraps the house in a continuous overhang. That is good for shading walls and windows and for keeping rain off siding, and it gives the house a lower, more horizontal look than a gable of the same pitch.

How a Hip Roof Is Built, Step by Step

Hip roofs can be stick-framed with rafters on site or built from a set of engineered trusses. The sequence is similar either way, but there are more distinct pieces than in a gable roof.

1. Wall plates are set. All four exterior walls carry a top plate at the same height, since the roof bears on every side.
2. The ridge and common framing go up. In a stick-framed roof, common rafters run from the long walls up to a ridge board. In a truss roof, standard trusses fill the middle of the house where the ridge is full height.
3. Hip rafters or hip trusses form the corners. In stick framing, a heavier hip rafter runs diagonally from each end of the ridge down to each outside corner of the house. In truss framing, a girder truss near each end carries a series of step-down hip trusses with flat tops that get progressively shorter toward the end wall.
4. Jack rafters fill in. Shorter jack rafters, or the truss equivalents, run from the end walls and side walls up to the hip rafters, each cut to a different length.
5. Sheathing covers the frame. Plywood or OSB is cut and fitted to each triangular and trapezoidal plane. FEMA’s mitigation guidance notes that sheathing layouts for hip roofs should follow the engineered wood industry’s recommended patterns, and that sheathing adds structural strength to the framing beneath it.
6. Underlayment, flashing and covering follow. Underlayment goes over the deck, flashing goes at walls, chimneys and penetrations and the covering goes on. Hips and ridges get special cap shingles or trim. Our roundup of roof underlayment picks compares products commonly used under shingles and metal.
7. Ventilation is installed. With no gable walls for vents, hip roofs rely on soffit intake vents and exhaust through the ridge, hip vents or roof-mounted vents.

The sloped ends brace the roof in every direction, which is why hip roofs are often described as self-bracing. The price of that strength is complexity. Every jack rafter is a different length, the hips need careful cuts and the sheathing and shingles must be trimmed along every hip line. Our guide to roof trusses explains how girder and step-down trusses carry those loads.

Main Types of Hip Roofs

Terms You Will See on a Quote or Inspection Report

• Hip. The sloped outside corner where two roof planes meet.
• Hip rafter. The framing member under each hip line, usually heavier than common rafters.
• Jack rafter. A shortened rafter running from a wall plate to a hip (or from a ridge to a valley).
• Girder truss and step-down trusses. The truss-framed equivalent of hip framing; the girder truss carries the shorter trusses near each end. Never cut or alter these members without an engineer.
• Ridge. The horizontal peak; on a hip roof it is shorter than the house is long.
• Valley. The inside corner where two planes meet on a cross-hip or a hip with additions. Our guide to roof valleys covers open, closed and woven valley details.
• Hip and ridge cap. Special shingles or trim that cover the hip and ridge lines.
• Pitch. Rise per 12 inches of run, such as 4:12 or 6:12.
• Square. 100 square feet of roof surface, the trade’s pricing unit. Hip roofs need more waste allowance than gables because of the angled cuts.

How to Tell Whether a House Has a Hip Roof

Roof shape is easy to misread on houses that mix forms, and it sometimes matters, for example when an insurance application, appraisal or roofing bid asks for it. A few quick checks settle it.

1. Walk around the house. If every exterior wall ends at an eave, with gutters at the top of each wall, the main roof is a hip. If any wall rises into a tall triangle of siding under a sloped roof edge, that section is a gable.
2. Look at the corners. On a hip roof, sloped lines run from the corners of the house up toward the ridge. Those lines are the hips, usually covered with a row of cap shingles.
3. Count the ridge length. A hip roof’s ridge stops short of the end walls. On a gable roof, the ridge runs the full length of the house.
4. Check the attic. From the attic hatch, a hip roof shows diagonal hip rafters or a girder truss with shorter step-down trusses near each end, and the roof slopes down toward you at the end walls instead of meeting a vertical wall.
5. Note combinations. Many homes have a hip main roof with a gable over the garage or a front porch, or a gable main roof with a clipped (half-hip) end. Describe each section separately on forms that ask for roof geometry.

If the answer affects insurance pricing or a wind-related discount, a roofer or inspector can document the geometry with photos, which is usually more persuasive than a homeowner’s description.

Hip Roof vs. Gable Roof

FEMA’s mitigation handbook notes that gable ends are subject to increased wind pressure in high winds and suggests considering moderate-sloped hip roofs with a 4:12 or 6:12 slope during design. That guidance is aimed at hurricane regions, but the principle carries to any site with strong winds: a roof with no tall flat end wall gives wind less to push against.

Pros and Cons of a Hip Roof

Advantages

• Better wind resistance. The four-sided shape braces itself and avoids the flat gable wall that wind can push or pull out of place.
• Continuous eaves. Every wall is shaded and protected from rain, and gutters can run around the whole house.
• Even snow and water shedding. Every side drains to an eave, so there is no single wall carrying all the runoff.
• Lower visual profile. The roof can look smaller and more horizontal, which some neighborhoods and HOAs favor.

Drawbacks

• Higher cost. More framing pieces, more sheathing waste and more cut shingles push up the price.
• Less attic space. The sloping ends reduce headroom and storage, and a hip roof is harder to convert to living space.
• More seams. Every hip is a line that must be capped, and cross hips add valleys, which are common leak points.
• Ventilation takes planning. A short ridge limits ridge vent length, so exhaust may need supplementing with other roof vents.

Typical Costs and Lifespan

Hip roofs typically cost more than gable roofs of the same footprint and pitch, both to frame and to reroof, because of the extra cuts, waste and labor. How much more depends on the number of hips and valleys, pitch, covering, access and local labor. The ranges below are typical, not quotes.

As with any roof, lifespan depends on the covering rather than the shape. Typical ranges are around 20 to 30 years for asphalt shingles and several decades for metal, shortened by hail, strong sun and freeze-thaw cycles at altitude.

Maintenance and Common Problems

Hip and ridge cap damage

The caps along each hip and the ridge sit at the highest-exposure lines on the roof. FEMA’s guidance for improving shingle wind performance recommends applying asphalt roof cement beneath shingles along eaves, rakes, hips and ridges to better attach them. Missing or lifted cap shingles after a windstorm are one of the most common hip roof repairs.

Valley leaks on cross hips

Wherever two roof sections meet, a valley carries concentrated runoff. Poorly flashed or worn valleys are a frequent source of leaks, especially where debris collects.

Snow in valleys and ice at the eaves

FEMA’s Snow Load Safety Guide notes that valleys at the intersection of sloping residential roofs accumulate greater snow depth than the rest of the roof, and that chimneys, dormers and other irregularities collect drifts. Because a hip roof has eaves on every side, ice dams can form along all four edges when attic heat melts snow that refreezes at the cold overhang. ENERGY STAR explains that a well-ventilated, air-sealed attic stays cold in winter and reduces ice damming. For overload warning signs, see our guide to roof snow load.

Under-ventilated attics

The short ridge and lack of gable walls mean ventilation has to be designed deliberately. Blocked soffits or too little exhaust can lead to heat buildup in summer and frost or condensation in winter. Our overview of roof vent types explains which exhaust options suit a hip roof.

What a Home Inspector Checks

The ASHI Standard of Practice requires a home inspector to inspect roofing materials, roof drainage systems, flashing, and skylights, chimneys and roof penetrations, and to describe the roofing materials and how the roof was inspected. On a hip roof, an inspector typically looks at:

• Hip and ridge caps for missing, cracked or lifted pieces
• Shingle condition across all four planes, including hail bruising and granule loss
• Valleys on cross hips for wear, debris and flashing condition
• Gutters and downspouts on every side
• From the attic: hip rafters or girder trusses, signs of sagging, staining at hips and valleys and ventilation balance
• Any evidence that trusses have been cut or altered

Depending on pitch, weather and safety, the inspector may walk the roof, use a drone or binoculars or view it from a ladder, and the report should state the method.

Front Range Notes

Wind is the most relevant regional factor. Foothills areas in Boulder and Jefferson counties see strong downslope winter windstorms, and a hip roof’s lack of tall gable walls is a genuine advantage there, provided the caps and edges are well fastened. Hail affects every roof shape on the Front Range, so the covering and its impact rating matter more than whether the roof is hip or gable. Snow loads are set by local building departments and rise with elevation; on hip roofs the main snow concerns are valleys and the eaves on all sides, where sliding snow can land on walkways, decks and entry doors. Snow guards or careful placement of entries can help on steeper hip roofs.

When to Call a Roofer or Inspector

Call a qualified roofer after a major wind or hail storm, if cap shingles are missing, if ceilings stain near a valley or exterior corner or if ice dams form regularly along the eaves. Buyers should make sure the roof and attic are covered in the home inspection and consider a dedicated roof evaluation for older or storm-exposed roofs.

More Questions About Hip Roofs

Are hip roofs better in high winds?

Yes, hip roofs generally perform better in high winds than gable roofs, because all sides slope and there is no tall flat gable end for wind to push against. Many hurricane-region building guides favor hip shapes for this reason.

Wind performance still depends on how the roof is attached. Hurricane straps, correct nailing of decking and shingles rated for high wind matter as much as shape. Some insurers in wind-prone states offer premium credits when a roof is documented as a hip roof during a wind mitigation inspection.

Does a hip roof have an attic?

Yes, a hip roof usually has an attic, but the sloped sides leave less usable headroom and storage space than a gable roof of the same footprint. The hips cut into the space at each end.

Converting a hip roof attic into living space is harder and often requires changing part of the roof to a gable or adding dormers. A hip roof attic still needs proper insulation and ventilation, which can be tricky because there are no gable walls for vents. Soffit and ridge vents usually handle airflow.

Can you put solar panels on a hip roof?

Yes, solar panels can go on a hip roof, but the triangular and trapezoidal faces offer less continuous area than a large gable plane. Installers often fit fewer panels or use several roof faces.

Because more faces may receive sun at different times, a hip roof may benefit from microinverters or optimizers. The federal residential clean energy credit for solar ended for systems completed after December 31, 2025, so homeowners should check state and utility incentives before pricing a project.

How do you ventilate a hip roof?

A hip roof is usually ventilated with continuous soffit vents for intake and ridge vents or hip vents for exhaust. Because hip roofs have a short ridge, exhaust area can be limited.

Roofers may add special hip vents, low-profile box vents, or powered vents where ridge length is not enough. Balanced intake and exhaust help prevent attic heat buildup, condensation and ice dams. Insulation must not block soffit vents, and baffles keep the air channel open at the eaves.

What is a hip and valley roof?

A hip and valley roof combines hips with one or more valleys, usually because the home has an L-, T- or U-shaped footprint. The valleys form where two roof planes meet in an inside corner.

This design adds visual interest and wind resistance but increases cost and leak risk. Valleys collect water and snow, so they need careful flashing or woven shingles and should be checked during roof inspections. More hips and valleys also mean more labor and material waste when the roof is replaced.
