A hip roof , hip-roof or hipped roof , is a type of roof where all the sides tilt down to the wall, usually with a fairly sloping slope (although a tent roof with a definition is a hipped roof with a steep slope rising to the top). So the roof of a hipped house does not have a roof or other vertical side to the roof.
The square hip roof is shaped like a pyramid. A hip roof at home can have two triangular sides and two a trapezoid. The hip roof on the rectangular plan has four faces. They are almost always on the same note or tilt, which makes them symmetrical about the midline. Hip roofs often have a consistent level fascia, which means the gutter can be fitted around. The roof often has sloping sideways.

Construction
Hip roof is more difficult to build than a pointed roof, requiring a more complex rafter or frame system. Hip roof can be built on various forms of plans. Each ridge is the center above the rectangle of the building below it. The faces of the roof triangle are called the tip of the hips, and they are limited by their own hips. The "hip" and hip rafters sit in an external corner of the building and up onto the ridge. Where the building has an internal angle, the valley makes a join between the sloping surfaces. They have the advantage of providing a solid and solid appearance to the structure. The roof (slope) may vary.

Use
In modern domestic architecture, hip roofs are usually seen in bungalows and cottages, and have been separated with styles such as American Foursquare. However, the hip roof has been used in a variety of architectural styles and in various structures.
Advantages and disadvantages
A hip roof is self-bracing, requiring less diagonal buffer than a saddle roof. Hip roof is thus much more suitable for storm areas than roof gable. The hip roof does not have large, flat, or slab edges to catch the wind and is inherently much more stable than the saddle roof. However, for the hurricane area, the roof must also be steep; at least 35 degrees from horizontal or steep on the slopes is preferred. When the wind flows over the roof of a shallow hip, the roof can behave like an airplane wing. Lift is then made on the lower side of the wind. The more flat the roof, the more likely it will be. Steeper hips roofs tend to cause winds to break through the roof, breaking the effect. If the roof slopes are less than 35 degrees from the horizontal, the roof will be subject to lifting. Larger than 35 degrees, and not just the wind blowing on it that suffers a stalling effect, but the roof is actually held in the wall by wind pressure.
The possibility of a hip roof loss, compared to a saddle roof on the same plan, is that there is less space in the roof space; access more difficult for maintenance; hip roof is more difficult to ventilate; and no saddle roof with windows for natural light.
Variant
Mansard roof
A mansard roof is a variation on the hip roof, with two different roof angles, the lower one is much steeper than the top.
Tented roof
tent roof is a polygonal hipped roof type with steep slopes rising to the top or intersection.
Gablet Roof or Dutch ivory saddle
Another variation is the English gablet (English terminology) or the roof of the Dutch saddle (US and Australasian term), which has a hips with a small saddle ( gablet i>) on it. This type simplifies roof construction; no tran girder required, but still has a flat wall and a consistent roof.
Hip half-roof
A half-hips, a cut roof or a head of a jewel has a gable, but the top point of the saddle is replaced with a small hip, squaring the top of the saddle roof. The lower edge of the hip half may have a gut that leads back to the rest of the roof on one or both sides. Both the gablet roof and the half-hipped roof are between the pointy type and fully waisted: the gablet roof has a saddle roof over the hips, while the half-hip roof has a hip on the saddle roof.
The half-waisted roof is very common in Denmark, Germany and especially in Austria and Slovenia. They are also typical of traditional wooden frame buildings in the Wealden area of ​​southeastern England.
Half hip roof is sometimes referred to as "Dutch hip", but the term is easily confused with "Dutch gable".
The pavilion roof
Hip roofs on square structures are usually found topping gazebos and other pavilion structures, also known as pyramid roofs.
Helmet Fringe or Roof Helm
The tapered roof is visible at the top of the tower or tower, oriented so as to have four ends of a saddle roof. See the Church of the Blessed Virgin Mary, Sompting, Speyer Cathedral, or Limburg Cathedral.
