Roof Slope Degrees Conversion

How to convert roof pitch to degrees.

Roof slope degrees conversion.

Degrees tan 1 43 calculated out this gives an angle of 23 27 degrees. Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials. Also see our page quick reference. Degrees tan 1 slope percent 100 example.

Many different professions use slope in describing an angle. See below after the table for directions on how to convert any roof slope from one form to another even roof slopes not shown in the table. Measure the rise of your roof. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.

Slope as angle for an elevation of 1 m over a distance of 2 m can be calculated as. 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. Let s say it is equal to 1 5 m. Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m.

The following table shows the roof pitch rise in run equivalents for all roof slopes in. Calculate the rafter length substituting these values into the following formula. 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. The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages.

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. For example in construction you may refer to the pitch of a roof or the grade of a slab. Calculate the roof pitch as the proportion of rise and run. To find the angle of a roof in degrees convert.

Degrees to roof pitch rise in run to see a table. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. Example slope as angle. Sangle tan 1 1 m 2 m 26 6.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Sometimes slope is referred to as pitch angle rise incline or grade. It s just a little math.
