Ridge Height Of Roof

Height of rafter or top chord of truss.

Ridge height of roof.

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. Angle the angle of a roof is the same as the roof s slope except instead of being. Carpenters measure roof pitch as inches of rise per 12 inches of run. A 1 in 12 roof pitch roof rises 1 inch for every 12 inches of run.

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. Height of roofing materials including plywood shingles and ridge vent on metal roof add height of purlin insulation if any metal roofing and ridge vent building with trusses and metal roof. With this design the ridge beam bears much more load weight than the ridge board on a standard stick framed roof. Roof pitch calculator results explained.

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. Rafters are nailed to the ridge board and run down to overhang the exterior wall. If your roof pitch was 5 12 and you measured the half measurement to center of 14 feet then your height to the ridge off the top of end wall of house is 5 83 feet.
