Hip Roof Ridge Beam

The first step in the process of erecting the hip roof is to get the ridge beam into place at the top of the roof.

Hip roof ridge beam. These are the measurements of the walls once covered with my sheathing and create the actual rectangle of the roof line. 16 10 6 feet. A structural ridge beam is a horizontal beam placed at the peak or ridge of a roof and is designed to carry much of the live and dead loads or weight of the roof structure by itself. This answer is useful.

6 feet plus 1 5 inches 73 5 inches for the ridge board. The rafters bear most of the weight of the roof. Ridge beams are required by code if the roof slope is less than 3 in 12 irc section r802 3. Determining the ridge beam height if you know the slope x in 12 you want to use for your roof framing design you can use it along with the run r to determine the height of the ridge beam.

Subtract the shorter wall length from the longer wall length and add 1 5 inches for the length of the ridge beam or board. The loads on the ridge beam are carried by vertical posts at the beam ends down through the building structural walls to the building foundation. Arguably the 4 diagonal boards the hip rafters are holding up the ridge board on their own but simply for load bearing purposes place supports under the ends of the ridge board and possibly one in the middle depending on. For example if the slope is 4 in 12 and the run is 12 feet the ridge beam height m will be 4 feet.

Span is 16 0 to center of posts supporting ridge beam. The ridge board holds them in place. Let s say i m building a shed that measures 10 feet by 16 feet. Live load 30 psf dead load 14 psf dead load manually increased for roof slope total load 44 psf.

Duration of load is 1 15 snow tributary length 12 0 exclude outer 6 ft of rafters which bear on outside walls. Ridge beam sizing is based on the span of the beam between supports and the amount of roof load supported by the beam. This answer is not useful. A ridge board or beam runs through the tops of rafters or trusses from end to end along a gable roof tying those framing members together.

As you can see the ridge board or ridge beam is holding up the jack rafters at the top of the incline. Place the 4 6 common rafters in their designated positions along the 2 longest walls and nail them firmly to the wall with a nail gun. A ridge beam is a structural member used to support the ends of the rafters at the ridge transferring it s loads to posts or gable end walls.
