While measuring tap to hear the spoken angle continuously as it changes.

16 12 roof pitch angle. In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally. You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof. Roof angles and rafter plumb cuts. Pitch angle incline slope they all can be used to refer to the steepness of a roof.

The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. A 12 12 pitch roof has a pitch angle of 45. 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. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Find the inverse tangent of the pitch to find the angle in degrees. Tap the button to start measuring and lay your device on an angle roof to measure pitch and angle and animate the diagram. Roof pitch defined and explained.

Or the colon can replace the slash as in 2 12 or 7 12. With a mobile device a button will appear. Locate its tangent or tan and follow the left row for you to read its corresponding degree. Divide the first part of the ratio by 12 to work out the pitch.

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. What degree angle is a 12 12 pitch roof. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Roof pitch designations are comprised of two numbers indicating a ratio.

Roof pitch is used to describe the slope or angle of the roof. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.
