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.
Tap the button to start measuring and lay your device on an angle roof to measure pitch and angle and animate the diagram.
On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.
Angle the angle of a roof is the same as the roof s slope except instead of being.
Roof pitch designations are comprised of two numbers indicating a ratio.
So use the 12 inch level as a constant run and 18 inch ruler as a variable rise.
While measuring tap to hear the spoken angle continuously as it changes.
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.
Or the colon can replace the slash as in 2 12 or 7 12.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
To convert between american roofing ratios and pitch degrees follow these steps.
