When you re arranging for repairs or roofing material your calculations will be way off if.

Often you express roof pitch as the ratio between the rise and the run in the form of.
Outside of the u s a degree angle is typically used.
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.
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.
As a reminder please don t forget to add height of rafter thickness of roofing material and ridge vent to the number that you ll get using our calculator.

Roof pitch calculator results explained.
The pitch of a roof determines the height of the ridge board that runs the length of the house.
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.
Angle the angle of a roof is the same as the roof s slope except instead of being.
Rafters are nailed to the ridge board and run down to overhang the exterior wall.
