Height Of Roof Feet

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.

Height of roof feet.

If your goal is to only calculate the roof height do not enter any numbers in wall height field and only use building width and roof pitch fields. The total run is the distance from the peak to the edge of the roof which in this case is the total width divided in half which is equal to 10 feet or 120 inches. For example if the peak is 4 feet and the total roof with is 20 feet the total rise is 4 feet or 48 inches. A 1 in 12 roof pitch roof rises 1 inch for every 12 inches of run.

For example if the roof rises 4 feet and the span is 16 feet twice the run then the pitch is 4 16 or 1 4. Carpenters measure roof pitch as inches of rise per 12 inches of run. Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure. The first step in a free roofing estimate is measuring the roof dimensions.

Rafters are nailed to the ridge board and run down to overhang the exterior wall. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. You will need to express this size in terms of square feet.
