Hip Roof Joints

A regular hip roof sits on a rectangular plan with four faces.

Hip roof joints.

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. 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. Now i can hang 2x6 ceiling joist 12 5 long from the external wall to the lvl beam. 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.

This is different from the huge framing members used for conventional framing of the ceilings and rafters. Here we consider two types of hipped roofs see picture. The procedure for the erection of a simple hip roof. 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.

A square hip roof is shaped like a pyramid. Rick arnold frequent contributor to fine homebuilding and the journal of light construction presenter at jlc live the katz roadshow the remodeling show. 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 hip roof on a rectangular plan has four faces.

Unit run of the hip. Secondly prefabricated hip roof trusses are much less expensive than stick roof framing since they come in short lengths of 2 4 stock. 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. Hip rafters are the diagonal rafters that span from the ridge at the top down to the corners of the roof.

For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17. The slope or slant of the roof is almost always the same and hence they are symmetrical at their centerlines. Hip roofs on houses could have two triangular sides and two trapezoidal ones.

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. 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. 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.
