Roof Style
What Is a Hip Roof?
Also called: hipped roof, hip-and-valley roof
A hip roof slopes upward on all four sides, the planes meeting at sloped ridges called hips, with no vertical gable end walls. The shape's low, self-bracing geometry makes it the most wind-resistant common roof form — the reason it dominates hurricane-prone coastlines.
In plain English
Where a gable roof shows a triangle wall at each end, a hip roof slopes there too — every side of the house gets a roof plane leaning into it. From above it reads as a rectangle of slopes meeting at angled ridges (the hips), like a low pyramid stretched along the house.
How hip roof works
The aerodynamics explain its storm record: with no flat end wall to catch wind and eaves at a uniform height bracing the structure all around, wind loads resolve into the roof from every direction — studies and insurance data after hurricanes consistently favor hips, and some coastal insurers price hip versus gable explicitly. Costs run higher: more complex framing, more cutting waste in the covering, and hips plus valleys to detail. Attic volume and ridge-vent length shrink versus an equivalent gable, so ventilation design works harder. For metal systems, hip roofs showcase the trim work — hip caps run down every corner, and shingle-style interlocking profiles wrap the geometry cleanly.
Why it matters for your roof
If you're on the coast or in open-plains wind country, roof shape is a structural decision: hips measurably outperform gables in extreme wind, and your insurer may already price that difference. Everywhere else, it's an aesthetic with real framing-cost and ventilation implications.
Common problems
More linear feet of hips and valleys to flash and cap; reduced ridge length constrains ridge venting; complex versions (hip-and-valley plans) concentrate water where slopes intersect.
Don't confuse it with
Not to be confused with the "hips" themselves — the sloped external corners where planes meet — versus the roof form as a whole.
- Hip vs gable roof
- Hip vs pyramid roof (a hip on a square plan)
- Hip vs Dutch gable (hybrid)
Regional & climate notes
Most relevant in: High-wind and hurricane-prone regions.
Frequently Asked Questions
Why are hip roofs better in hurricanes?
No flat end walls to catch wind, uniform eave bracing on all sides, and geometry that resolves uplift into the structure — post-storm studies and insurer pricing both reflect the advantage.
Is a hip roof more expensive to build or roof?
Yes, moderately: more complex framing, more covering waste from angled cuts, and more hip/valley detail work than an equivalent gable.
How do you ventilate a hip roof?
Shorter ridges mean less ridge-vent length, so designs lean on generous soffit intake plus hip-adapted or supplemental exhaust to keep the attic loop balanced.
