Ridge Height Of Roof

Angle the angle of a roof is the same as the roof s slope except instead of being.

Ridge height of roof.

Rafters are nailed to the ridge board and run down to overhang the exterior wall. The finished ridge beam height z above the top of the wall will be m plus the y 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 for example if the slope is 4 in 12 and the run is 12 feet the ridge beam height m will be 4 feet.

Determining the ridge beam height. Height of rafter or top chord of truss. A timber frame roof has rafters and a ridge beam as with stick framing but the ridge is a large structural beam that the rafters sit on top of or sometimes fit into notches cut into the beam. Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

Carpenters measure roof pitch as inches of rise per 12 inches of run. The pitch of a roof determines the height of the ridge board that runs the length of the house. With this design the ridge beam bears much more load weight than the ridge board on a standard stick framed roof.
