Hip Roof Joints

Here we consider two types of hipped roofs see picture.

Hip roof joints.

A hip roof on a rectangular plan has four faces. Hip rafters are the diagonal rafters that span from the ridge at the top down to the corners of the roof. Unit run of the hip. The longer sides have a trapezoidal shape while the sides at the front and back have a triangular shape and are called hip ends.

The slope or slant of the roof is almost always the same and hence they are symmetrical at their centerlines. Hip roofs tend to be stronger than gable roofs but there is an increased cost in building a hip roof as it s a more complicated structure that requires more building materials and effort. 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. The procedure for the erection of a simple hip roof.

If the wall plates are all square of equal lengths then the hipped rafters would form a pyramid shape like the picture above normally a roof is rectangle and there are more yellow common rafters. While hip roofs are stronger and more wind resistant they can be prone to leaks due to the increased level of joins required so care must be taken to provide proper water protection at all joints. As a follow up to my previous post on a 18x25 hip roof can i place an lvl beam 18 span so that the ceiling is now essentially split into 2 sections each one 18 wide and 12 5 long. Advantages of prefabricated hip roof trusses.

Hip roofs on houses could have two triangular sides and two trapezoidal ones. Thus a hipped roof house has no gables or other vertical sides to the roof. Firstly premade hip roof trusses span a longer distance and can do without the presence of inside weight bearing walls. But here it will be different since the hip rafter doesn t lie at 45 degrees to the commons.

They are almost always at the same pitch or slope which makes them symmetrical about the centerlines. Secondly prefabricated hip roof trusses are much less expensive than stick roof framing since they come in short lengths of 2 4 stock. The procedure for the erection of a simple hip roof. A hip roof hip roof or hipped roof is a type of roof where all sides slope downwards to the walls usually with a fairly gentle slope.

A regular hip roof sits on a rectangular plan with four faces. Now i can hang 2x6 ceiling joist 12 5 long from the external wall to the lvl beam. In a hip roof with equal pitches the unit run of a hip or valley rafter is 17 inches for every 12 inches of run in the main roof. This is different from the huge framing members used for conventional framing of the ceilings and rafters.
