How To Convert Roof Pitch Into Degrees

To do this simply convert the rise and run as a fraction to a decimal form eg.

How to convert roof pitch into degrees.

In other parts of the world where metric is used degrees are actually commonly used for roof pitch because the base 10 nature of the standard units converts cleanly with a simple tool. Note the other number it will be vertical where the line of the roof intersects. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. Line up the level so that the 12 on one end lines up with the peak.

Here is a handy conversion chart to convert roof pitches to degrees in case you don t have time for all that math. 8 12 pitch 33 75 degrees. Hip rafters are different. Select inches to enter decimal inches or millimeters for metric.

However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement. First convert the pitch to a slope. When determining the angle of a hip use 16 97 instead of 12 in the formula above. With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch.

Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. How to convert roof pitch to degrees to find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope. Directly measure roof pitch angle and calculate pitch and angle on phone or tablet. What you need to do is find the peak of your section of roof from the side on a ladder.

Roof pitch and corresponding angles. Rise run rise run slope. The chart shows plumb cuts so to get the level cut remember that 90 plumb cut level cut. If that line is for example 9 then your ration will be 9 12.

Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof. If a roof or ramp rises 4 in a length of 12 the pitch is 4 in 12 which is 18 43 or 33 33 grade enter base length to calculate rise and diagonal for current pitch angle. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
