Hip Roof Geometry

It is sloped on all sides with the slopes meeting in a peak if the structure is square.

Hip roof geometry. N s or e w for a gable roof. The slope or slant of the roof is almost always the same and hence they are symmetrical at their centerlines. Red triangles are common rafters blue triangles are hips. Or with the ends sloped inward toward a ridgeformed by the adjacent sides if the structure is rectangular.

A hipped roof is sloped in two pairs of directions e g. From your average hip roof calculator to something more specific like a hip roof rafter calculator there is plenty to consider with this kind of calculation. One major factor to consider on a hip roof is that there is often very little peak or ridge area at the top of the roof. See above cross hipped.

A hip roof on a rectangular plan has four faces. You could layout the roof full scale with each framing member drawn to it s actual width if the walls are not yet framed. The hip refers to the external angle formed where two adjacent sides meet. They are almost always at the same pitch or slope which makes them symmetrical about the centerlines.

Thus a hipped roof house has no gables or other vertical sides to the roof. See above dutch gable gablet. The result of joining two or more hip roof sections together forming a t or l shape for the simplest forms or any number of more complex shapes. Here we consider two types of hipped roofs see picture.

A regular hip roof sits on a rectangular plan with four faces. Pt2 in depth mixed pitch hip and valley roof cutting math theory and technique series. However a four sided roof is usually a hip roof. Hip backing angle 15 4 for a good straight fascia add an extra inch or 2 to the tails of all your rafters total length.

Using geometry draw out the triangles representing each framing member to calculate dimension all of the theoretical lengths of the rafters. The reverse hybrid of a hipped and a gable roof. Hip roofs on houses could have two triangular sides and two trapezoidal ones. Hip roofs when you think of a roof that just has a front and a back that is usually a gable roof.

Here you can calculate hip roof parameters by hip raise and base parameters. 1 pyramid hip roof roof base is a square roof sides are identical isosceles triangles 2 hip roof roof base is a rectangle two sides are identical isosceles triangles and two sides are identical trapeziums. A hip roof has no vertical ends. The longer sides have a trapezoidal shape while the sides at the front and back have a triangular shape and are called hip ends.

A hybrid of a gable and a hipped roof. N s and e w compared to the one pair of direction e g. A square hip roof is shaped like a pyramid. To do this your best bet is definitely finding a good hip roof construction calculator so that you can work it all out in a timely and simple fashion.
