Hip Roof Ridge Support

This article describes and illustrates the different types of support that prevents roof sagging and wall bulging at buildings including definitions of collar ties rafter ties and structural ridge beams.

Hip roof ridge support.

A square hip roof is shaped like a pyramid. Ridge beam sizing is based on the span of the beam between supports and the amount of roof load supported by the beam. A dutch hip roof is a combination of both the hip roof and gable roof features. Some of these can support the roof and prevent ridge sagging and wall spreading.

Please note i have not drawn the gable end framing yet which will obviously support the ridge beams. It is sometimes also referred to as a dutch gable roof precisely because it contains both roof style features. I am putting up a 20 x40 one level building that will have a conventional hip roof w 6 12 pitch there will be ceiling joists 2x8x12 secured in the center and hung from the ridge beam by 2x4 s. The second picture is the coop design i am using for a reference.

Collar ties rafter ties tension beams structural ridge beams. The gable portion of a dutch hip roof is usually placed at the end of the roof ridge and sits on top of the plane of the hip roof. Note the 2x6 beam in the center of the room to support the 2 roofs. The most classic type of house roof is a gable roof which has two roof planes and a triangle topped wall at either end known as a gable wall.

A variation on this is the hip roof which has no gable walls. The first picture is the coop i am building. Instead it has an additional roof plane at each end of the central horizontal ridge. Does this seem adequate to hold this roof up without having a load bearing support wall in the interior.

Ridge beams are required by code if the roof slope is less than 3 in 12 irc section r802 3. 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 although a tented roof by definition is a hipped roof with steeply pitched slopes rising to a peak.
